Lạc – món ăn vị thuốc chữa xuất huyết giảm tiểu cầu Thứ Hai 1.11.2010 | 16:39 (GMT + 7) (LĐO) - Bữa cơm mùa đông với muối lạc lạ miệng giúp bạn có thể ăn 2 3 bát cơm ngon lành. Vừa là thực phẩm chế biến được nhiều món ăn lạc còn là một vị thuốc quý trong chữa bệnh. Lạc rất có ích trong chữa bệnh Lạc rất có ích trong trị bệnh. Lạc rang là món khoái khẩu cho cánh mày râu bên bàn nhậu. Lạc rang muối cũng là món ăn hấp dẫn các bạn sinh viên. Theo đông y lạc rang còn rất có ích trong trị bệnh xuất huyết giảm tiểu cầu. Dùng lạc rang chín 180g hoặc lạc nhân sống 150gchia ra 3 lần ăn hết trong ngày ăn liên tục 1 tuần giúp tăng tiểu cầu trong máu đối với bệnh nhân bị xuất huyết giảm tiểu cầu. Nếu tiểu cầu trong máu vẫn còn giảm thì cần tiếp tục ăn. Khi ăn hoặc chế biến vị thuốc không nên bỏ vỏ lụa của lạc. Vì vỏ lụa có tác dụng cầm máu rất tốt có khả năng cầm máu gấp 50 lần lạc nhân dùng tốt cho các bệnh xuất huyết trong ngoài bệnh máu chậm đông ngoài ra có thể kích thích tủy xương tái tạo tiểu cầu máu làm giảm thời gian xuất huyết tăng cường khả năng co lại của mao mạch. Vỏ lụa của lạc có tác dụng cầm máu tương đối tốt đối với bệnh xuất huyết giảm tiểu cầu thiếu máu do khả năng tái sinh gặp trở ngại mao mạch giãn nở xuất huyết do di truyền xuất huyết đường tiêu hóa chảy máu răng ngoại thương. Trong vỏ cứng của củ lạc có chất luteolin có tác dụng hạ huyết áp chất beta - stosterol có tác dụng hạ mỡ máu. Ngoài ra các bộ phận của lạc dùng làm thuốc rất quý. Cây lá củ nhân và màng bọc ngoài của nhân dầu lạc... có những tác dụng như dưỡng huyết bổ tỳ nhuận phế hóa đàm và chữa được một số căn bệnh như thai phụ bị phù loét dạ dày và hành tá tràng... Không phải thực phẩm nào cũng có ích với tất cả mọi người. Lưu ý những người có thể hàn thấp đình trệ và tiêu chảy kiêng ăn lạc. Ăn nhiều lạc rang quá sẽ dễ bị động hỏa (người cồn cào khó chịu dễ cáu giận). Tuyệt đối không ăn lạc đã bị nấm mốc.

Hồng - vị thuốc quý

By leukaemia

Hồng - vị thuốc quý

Hồng là loài cây ăn trái được trồng ở nhiều vùng nước ta. Quả hồng thường được chia thành "hồng ngọt" và "hồng chát" (còn gọi là "hồng ngâm"). Nhiều bộ phận của quả hồng cũng như cây hồng có thể dùng làm thuốc". Phấn ở quả hồng (thị sương) có công hiệu thanh nhiệt nhuận táo tan đờm giảm ho là vị thuốc tốt dùng chữa viêm niêm mạc miệng lưỡi viêm rát họng ho do phế nhiệt. Núm cuống quả hồng còn gọi là tai hồng hay thị đế có tác dụng giáng khí trị nôn ợ hơi. Thuốc Đông y có bài "Thị đế thang" "Thị đế tán" nổi tiếng chữa nôn ợ hơi thở nóng... khá hiệu nghiệm. Lá hồng có tác dụng hạ huyết áp cầm máu diệt khuẩn tiêu viêm kéo dài tuổi thọ. Uống trà lá hồng lâu ngày sẽ làm cho mạch máu mềm đi chữa xơ cứng động mạch và trị mất ngủ. Dưới đây là một số ứng dụng cụ thể từ quả hồng và cây hồng: - Tăng huyết áp: Lấy quả hồng tươi ép lấy nước (thị tất) hoà với sữa hoặc nước cơm uống ngày uống 3 lần mỗi lần nửa chén. Có tác dụng dự phòng "trúng phong" (tai biến mạch máu não) do tăng huyết áp. - Chứng ưa chảy máu (hemophilia - huyết hữu bệnh): hồng khô 30g ngó sen 30g hoa kinh giới 15g đem sắc uống. Khi uống hoà thêm 10ml mật ong mỗi ngày 1 thang liên tục trong 15 ngày (một liệu trình) nghỉ vài ngày rồi lại uống tiếp liệu trình khác cho tới khi khỏi. - Chữa tiểu tiện ra máu: Lấy thị đế (tai hồng) đem thiêu tồn tính (rang to lửa hoặc đốt cho đến khi mặt ngoài cháy đen như than nhưng bên trong vẫn giữ nguyên màu) sau đó nghiền mịn cất đi dùng dần. Ngày uống 2 lần vào lúc đói bụng mỗi lần 6g chiêu bột thuốc bằng nước cơm hoặc cháo loãng. - Trĩ nội đại tiện xuất huyết: Lấy quả hồng khô 12g sắc uống hoặc nấu cháo ăn ngày 2 lần. Cũng có thể lấy quả hồng khô rang vàng tán mịn uống ngày 3 lần mỗi lần 6g. - Chữa các loại xuất huyết bên trong (chảy máu dạ dày ho ra máu do lao trĩ nội...): Lấy lá hồng rụng mùa thu rửa sạch phơi khô nghiền mịn ngày uống 3 lần mỗi lần 5g. - Chữa ban xuất huyết do giảm tiểu cầu: Cũng lấy lá hồng rụng mùa thu rửa sạch phơi khô nghiền mịn ngày uống 2 lần vào buổi sáng và buổi tối mỗi lần 3g liên tục trong 1 tháng. - Chữa nấc: Lấy cuống quả hồng 3 - 5 cái thêm 5 lát gừng sắc uống. Nếu thêm khoảng 5 - 6g đinh hương càng tốt. - Kiết lỵ viêm ruột: Lấy hồng khô thái nhỏ phơi khô sao vàng rồi tán thành bột mịn để uống dần ngày uống 3 lần mỗi lần 5g chiêu bằng nước đun sôi. - Lưỡi môi lở loét: Lấy thị sương 10g bạc hà 5g hai thứ trộn lẫn với nhau đem nghiền mịn bôi vào chỗ môi bị lở rất mau khỏi. Hoặc chỉ cần lấy thị sương ngày bôi 3 lần vào chỗ bị lở vài ngày cũng sẽ khỏi. - Da bị dị ứng: Quả hồng còn xanh 500g giã nát thêm 1.500ml nước vào trộn đều phơi nắng 7 ngày bỏ bã phơi tiếp trong 3 ngày nữa rót vào lọ dùng dần hàng ngày lấy bông thấm thuốc bôi vào chỗ da bị dị ứng 3 - 4 lần. - Thổ huyết ho khạc ra máu: Hồng sấy khô tán bột ngày dùng 3 lần mỗi lần 3g. - Viêm da lở loét: Vỏ quả hồng 50g đốt toàn tính tán nhỏ trộn với mỡ lợn bôi. - Tránh thụ thai: Núm cuống quả hồng 50g sấy khô tán nhỏ chia đều thành 6 gói trước và sau khi hành kinh uống 1 lần mỗi lần 1 gói liền trong 3 chu kỳ. Quả hồng tuy bổ nhưng không phải ai cũng dùng được. Theo kinh nghiệm của đông y người tỳ vị hư hàn có đàm thấp bên trong tiêu chảy đang bị cảm lạnh không được ăn hồng; sau bữa ăn có món tôm và cua không nên ăn hồng; ăn ngay một lúc quá nhiều hồng có thể dẫn tới đau trướng bụng buồn nôn tiêu chảy... Đặc biệt khi đói bụng không nên ăn quá nhiều hồng nhất là hồng chưa thật chín và ăn cả vỏ. Bởi vì khi vào dạ dày một số thành phần trong quả hồng có thể kết hợp với dịch vị tạo thành những chất kết tủa không tan; lúc đầu chỉ nhỏ như hạt mơ dần dần có thể to như nắm tay gọi là "thị thạch" (sỏi hồng).

Cơ quan này tiến hành khảo sát nước uống sau khi hóa chất này được phát hiện trong nước giải khát tại Hoa Kỳ.

Các hãng sản xuất nước ngọt từ 15 năm nay đã biết được rằng chất bảo quản sodium benzoate (còn gọi là chất chống thối) sẽ tạo ra benzene nếu kết hợp với acid ascorbic (còn gọi là vitamin C). Vì thế các nhà dinh dưỡng học và người tiêu thụ đặt câu hỏi tại sao đến bây giờ benzene vẫn có trong nước giải khát?

TP.HCM: Benzen trong không khí... quá cao!

Trong khuôn khổ hội thảo chất lượng xăng dầu và ô nhiễm môi trường Trung tâm Dịch vụ phân tích thí nghiệm công bố một kết quả nghiên cứu của các nhà khoa học về tình hình ô nhiễm benzen toluen xylen trong không khí trên địa bàn thành phố. Kết quả nghiên cứu dựa trên việc lấy mẫu trên một số trục đường giao thông chính tại thành phố.

Theo đó nồng độ benzen trung bình là 33 6mcg/m3 không khí cao gấp 6 72 lần tiêu chuẩn của Tổ chức Y tế thế giới. Nếu dựa vào kết quả này để tính toán nguy cơ mắc bệnh bạch cầu khi phơi nhiễm benzen trong không khí cao gấp 5 4 lần giá trị chấp nhận tối đa (1mcg/m3).

Điều này đồng nghĩa với việc đã có dấu hiệu báo động ô nhiễm benzen trong không khí ven các trục đường giao thông chính của TP Hồ Chí Minh. Cũng theo tính toán của các nhà khoa học thì cảnh sát giao thông có nguy cơ mắc bệnh bạch cầu cao gấp 540 lần so với người không bị phơi nhiễm benzen.

Acai Berry Research For Leukemia Cells Treatment 

The acai berry research study conducted by the University of Florida brought some significant results related to the abilities of the fruit. According to the study the acai berry pulp can be effective in killing 35 to 86% of leukemia cells in an individual.

According to the research the extracts from acai berry have the ability to trigger a self-destructing mechanism that is sufficient to kill a considerable percentage of the leukemia cells in the body. Though the research needs further study to confirm the actual benefits of acai in treating the cancer it definitely encouraged the experts to advance further in the direction.

In the acai berry research conducted by the lab in the university as many as six different acai berry extracts were prepared and each extract was prepared in seven varying concentrations. Out of them four acai berry extracts were found to kill up to 86% of leukemia cells when applied for exact 24 hour time period. The research had proved the fact that increased consumption of fruits on regular basis can help in decreasing the chances of cancer apart from heart diseases and other problems.

Acai berry is known to be the rich source of antioxidants. In the next section you can learn about a research study on this aspect of acai.

According to the acai berry research the fruit contains 8g protein per 100g which is equivalent to the amount of protein found

Acai Berry Research Proves Great Amount Of Antioxidants In Acai Fruit 

Texas A&M University made one of the initial attempts to conduct acai berry research and deliver some good analysis about the fruit. One of the studies conducted by the experts in the university proves that the human body capably absorbs the important antioxidants present in acai berry. It should be noted that these experts were among the first ones to study the nutritional and antioxidant aspects of the fruit.

Aging is one of the many issues that can be solved with the help of antioxidant quality of acai berry. This is because the antioxidants are of great help in fighting against the damage caused by free radicals and inflammation that can otherwise accelerate the process of aging.

In this particular acai berry research 12 volunteers were given acai berry in the form of juice or pulp. Analysis of blood and urine samples of the volunteers after 24 hours displayed an increase in the activities of antioxidants in the body. Anthocyanins and antioxidant flavonoids are among the antioxidants that are readily absorbed from acai extracts by the human body.

It has already been proved that acai berry has up to 30 times more anthocyanins as compared to red wine. With such inspiring results being delivered one can obviously have enough reasons to trust this super food.

Acaiberry-information.com happens to be the informative guide about acai berry and various health benefits associated with it. The information available on the websites has been compiled from the various sources of acai berry research and thus can help one get familiar with some good aspects of the fruit. Information related to recommended amount of acai berry products acai berry solutions for various health issues different forms of the fruit and other things can be obtained using the website.

The acai berry research programs have proved that 100g of acai berry fruit contains as much as 14g of fiber.

Can Acai Berries Really Help To Fight Cancer?

By leukaemia

Can Acai Berries Really Help To Fight Cancer?

Whilst scientists are keen to investigate and prove the benefits of so-called "super foods" we - the consumer - are keen to reap the rewards of these investigations. With the acai berry s popularity soaring scientists have been working overtime to see just what it is that this unique fruit can do for as. As the multitude of proven tangible benefits offered by the humble acai berry mount almost daily so the popularity of the berry grows even quicker in response.

It was with great excitement that I read a University of Florida study on the effects of the acai berry upon leukemia cells. The lab tests executed by the boffins in the Florida labs showed that extracts from acai berries triggered a self-destruct response in up to 86% of leukemia cells tested. The tests were it seems in direct response to some of the claims made by manufacturers distributors and retailers of acai-based products. Stephen Talcott is quoted in the article as saying:

Acai berries are already considered one of the richest fruit sources of antioxidants. ... This study was an important step toward learning what people may gain from using beverages dietary supplements or other products made with the berries.

Acai berries are not alone in having the properties necessary to attack leukemia in controlled lab tests. Grapes guavas mangoes and many other fruits contained the antioxidants which were identified as being responsible for the startling results. Berries - and acai berries in particular - are renowned for having a very high ORAC (Oxygen Radical Absorbance Capacity - the measure used to determine the antioxidant capacity of different foods) rating and may be particularly effective at combating the cells.

The type of antioxidant that produces this behavior is the anthocyanin. Anthocyanins are particularly effective against molecules called ‘free radicals which are harmful to some of our body s cells. Free radicals are produced either as by products of the body s functions or introduced into our system by pollutants such as cigarette smoke and gas fumes. At the very extreme free radicals can actually change the DNA of a cell and thus introduce a cancer into the body.

Talcott went on to explain that although the test results were very encouraging and showed good activity against the cancer cells it did not necessarily mean that acai berries could prevent or cure leukemia in people. When active leukemia in people was considered there are too many variable factors that come into play which may influence the antioxidants chemical activity. This is of course not to say that it doesn t help against leukemia cells in humans just that scientists are unable to prove anything as yet.

This is undoubtedly a very exciting discovery but why has it taken until now for scientists to uncover the potential benefits of acai berries? Stephen Talcott again:

One reason so little is known about acai berries is that they re perishable and are traditionally used immediately after picking. Products made with processed acai berries have only been available for about five years so researchers in many parts of the world have had little or no opportunity to study them.

It is generally recognized that an increased consumption of fruit and vegetables of most types can be closely associated with a decreased risk of contraction of a number of afflictions including heart disease and cancer. Finding that the acai berry is super-charged with the necessary antioxidants is a very exciting step toward to making the world a healthier place.

Studies Show Cancer Cells Die With Acai Berries

By leukaemia

A recent University of Florida study has demonstrated the cancer fighting benefits of an extract from the acai berry. This extract has proven effective on cancer cells which have been unaffected by other therapies which have been tried. This is only the first of many planned studies on the effects of acai berries on cancer.

When testing leukaemia cells with the extract from this berry a staggering 86% of the cells self-destructed. Although the benefits of acai berries were already known as a great source of antioxidants this has been an astounding discovery. An assistant professor at University of Florida s Institute of Food and Agricultural Services has confirmed that 86% in not an exaggeration.

There may be other fruit-based antioxidants and other compounds which are effective against leukaemia and other cancers but all of the research done so far is preliminary since there are many other factors which must be accounted for in these studies. The data from the University of Florida acai study however shows great promise thus far.

In Australia the acai berry has swiftly grown in popularity as have diets rich in this fruit noni goji and mangosteen. One sees a lot of promotions for juices and other products made from these fruits. These fruits not coincidentally have also been shown to be high in antioxidant content.

A study from March of this year in Brisbane Australia focused on the differences between the antioxidants sourced from olive leaves and those occurring in these tropical fruits and juices. This study showed some antioxidant properties to be present in olive leaves but those done on acai berries have been more conclusive in their results.

The most interesting of these studies are of course the ones which have been done on fruits and cancer. U.S. researchers are working tirelessly to find a cure for cancer especially leukaemia. Australia is doing the same in regard to cancer research. Leukaemia is the top disease related cause of death in children aged 20 and younger worldwide. For this reason leukaemia research is a priority for many nations around the globe.

So far all of the research is still preliminary and there is much more to be learned about the anti cancer properties of these fruits. The acai berry for example contains nearly 75 chemical compounds and the exact properties of many of these are as yet unknown. The acai berry is a difficult fruit to study due to its extremely short shelf life.

The acai berry is roughly the same size as a blueberry and is dark purple when ripe. They contain a single seed and decompose rapidly if not frozen or used straightaway. Since this berry is native to the Amazon River basin freezing these berries for a long trip is not always a viable option.

The most accessible option for importing into Australia is the acai powder which results from the pulp being dehydrated and freeze-dried. The resulting powder is easier and cheaper to export and can be used to make pure acai supplements that have all the nutritional benefits of the original fruit. Moreover the freeze-dried powder has all the health-giving properties of the berry itself.

Although studies are only preliminary for now the hope that one day leukaemia and other cancers will be cured is still alive. The sad fact is that leukaemia strikes more children than adults. For the children who suffer from this disease the day that such a cure is found will be a great day indeed.

    catsears

    This next edible weed only occurs in one small area here - down where the old house was that we initially lived in when we moved to Chandler in 1988. Plantain occurs there as well but nowhere else on our property. This is interesting to me and one possible reason I found was that it this plant prefers low phosphate and potash soils - so maybe the soil in that area is low in these nutrients.

    Binomial name: Hypochaeris glabra
    Common name : Catsears flatweed false dandelion

    catsear name because the tip of the leaf is a bit like the feline ear

    Identification:

    Catsears is also called flatweed - indicating it s growth habit. The rosette is about 500mm diameter. There is a tap root but it pulls out readily. It has long narrow leaves 200-250mm x 50mmwide with smooth or wavy margins and rounded end (compared to dandelion which is much more irregular) It is way more common than dandelion as well here. One variety is hairy another is smooth. The leaves on the variety I have feel bumpy to touch and have sparse fine hairs along the leaf margin and the midrib this indicates that they are H. glabra. The flower stem is 700mm long hollow and hard to break. About half way up it branches 4 or 5 times and bears a dandelion type flower.

    History :

    This plant has probably been eaten by humans for a longtime and is eaten in the Mediterranean area today especially in Sicily and Crete where it is seasoned with oil and fried with garlic and other ingredients. The pollen is an important food source for bees although it is somewhat deficient in certain amino acids.

    Nutrition :

    Nothing much definite - John Kallis (ref below) reports that it probably contains high levels of Calcium Phosphorus and Copper. The flowers contain lutein and carotenoids. The leaves also would have carotenoids and polyphenols with high antioxidant activity. The phosphorus report is a little surprising as elsewhere on the net I found a report that it tends to grow on low phosphorus and potash soils.

    What parts to eat:

    Cut young leaves with a pair of scissors - a little sap exudes that discolors the end - trim this off before cooking. Blanch to remove any bitterness and treat as a spinach substitute . The young flower stalks and flowers are edible as well although we have not tried them. Similarly the tap root can be dried ground and used as a coffee substitute. Once again we have not done this either.


    Pubmed search :

    Catsears is associated with a disorder in horses called stringhalt. Horses affected by it have evidence of nerve damage in the hind legs. However the quantities eaten by a horse would of course be way more than humans would eat but nonetheless it is a consideration I guess. Otherwise not much else found.

    Conclusion :

    Another of the edible weeds - there are some gaps in knowledge but I think it is safe enough to eat on a regular basis. We find the taste a bit bitter with some aftertaste whereas Tim Low and John Kallis in the reference books I use
    report that it is tasty and palatable - we need to experiment more with harvesting this plant and be more selective of very young leaves.

    garden - general

    As I am working fulltime for the next few weeks I have less time to prepare my blog items as per usual - I have a few almost ready that need further workup.

    Here s a few photos from around our yard some of which I plan on explaining later especially the lessons learnt constructing them.

    The first is a general backyard view - the south of our house with my workshop and 2 of the aquaponics systems with vegetable garden beside.

    Another photo is of the root cellar made to look like an old mine site.
    Beside that is a container that has had a facade painted by our daughter (who is really talented with art things) to make it look like an old Maori Whare (house)

    The other photo is of the backyard dunny -story about this later. 12 mm of rain overnight here and more today - most welcome.

    Shepherd s purse

    Binomial name: Capsella bursa-pastoris
    Common name : Shepherd s purse

    Identification:

    It occurs in autumn and winter on our property (SE Queensland). The basal rosette is like dandelion and sowthistle but the leaves are quite narrow with some shallow regular serrations and with sparse in number very fine hairs along the edge of the leaf. There is a core string like dandelion
    and catsears if you try and pull a leaf
    apart. The seed spikes are quite distinctive with seed pods that look like small hearts.


    History:

    Originally from Eurasia but now cosmopolitan. Probably it has been used by humans for a long period - seeds were found in an archaeological site in Turkey dating from 5800B.C. In ancient Greece it was used as a laxative and in the middle ages as a haemostatic agent (to stop bleeding). In a certain part of China it is used as a substitute for bok choy in wontons. It is sold in Asia as a vegetable and a larger variety has been developed.

    Nutritional:

    (per 100gm leaves)
    omega 3 fatty acids 233 mg
    RAE (retinal A equivalent) 433mg
    B carotene 5 200IU Vit C 104mg (an orange is about 80mg) + some minerals.
    These levels are very similar to Spinach (Spinacea oleracea) apart from the omega 3 fatty acids which is 138mg for spinach.

    ref : Kallas J Edible Wild Plants - Wild foods from Dirt to Plate Gibbs Smith 2010

    What parts to eat:

    young leaves in a salad older leaves as a potherb ( reduces alot when boiled) taste is reported as peppery - it is really only mildly so in the plants we have growing.

    Medical: (Pubmed - search term Shepherd s purse)

    Not much to report - undoubtedly though it has excellent anti-oxidant activity by virtue of the RAE and carotenoid content. There was a report of several pigs dying from nitrite poisoning from eating weeds with Shepherd s purse implicated ( abstract 60). Not medically related but interesting was a use of Shepherd s Purse for bioremediation of contaminated soil (it worked well). Another abstract indicated that it inhibited melanocyte activity and thus may have a skin whitening effect (abstract 26).

    Conclusion:

    Another quite nutritious edible weed however there are lots of questions - if it stops bleeding externally what effect does it really have internally. I would like to see some proper trials on this especially with regard to blood pressure if it does indeed cause vasoconstriction. John Kallis in his book indicated that a serve of this weed gave him a slight headache for 5 hours - I would be concerned that this was related to an increase in blood pressure.
    So - just eat a few leaves mixed in with other greens would be my advice until there is some decent evidence available.

    Stinking Passionfruit

    Binomial name : Passiflora foetida
    Common name : Small passionfruit or stinking passionfruit

    the foetida part of the binomial name refers to the smell of the foliage when it is crushed.


    This is another weed in my property that I leave now as the small yellow fruit are quite sweet to eat ( the pulp part). It is a seasonal weed being present in summer and is not too invasive on my property. It seems quite happy growing in a couple of quite dry areas.

    Identification:

    It is a vine like normal passionfruit with soft pale green velvety leaves.
    The fruit is enclosed in 3 small spidery bracts - the ripe fruit is yellow
    with a thin skin and drops to the ground. I have found some chewed fruit
    on the ground so no doubt some furry friends like it as well. The bracts exude a sticky substance with digestive enzymes that can trap small insects.It is considered to be a protocarnivorous plant because of this ability but it is uncertain if the plant derives any benefit
    from it.

    History and Uses:

    The leaves are eaten in Asia - cooked or steamed with rice
    The Vietnamese use the leaves to make a tea for insomnia.

    Parts to use

    pulp from ripe seeds as substitute for normal passionfruit.
    leaves - do contain cyanide and thus should to be cooked.


    Medical (pubmed and Scirus) reports:

    One scientific article of interest I found was a report of an extract of the stem being used as a skin whitening agent.

    An extract of this plant inhibited 2 enzymes (MMP-2 and MMP-9) involved tumour growth and spread thus it many have an anticancer effect.

    It may also have an insect repellant effect (ermanin -a flavonoid component was found to do this).

    A leaf extract also was found to have considerable antibacteral action against Strep viridans and 3 other important human pathogens.


    Conclusion:

    The pulp of the fruits as mentioned is sweet to eat. We have not used the leaves at all but it seems they can be utilised as a potherb. Posted by Tom at 6:00 PM 1 comments Labels:

    Lesser Swinecress

    This weed is prolific at present mainly in an area of our lawn that died back after grass grubs proliferated after a wet spell towards the end of summer.

    binomial name : Coronopus didymus
    common name : Lesser Swinecress

    Identification:

    This is an annual plant that I mainly see in winter. It belongs to the brassica family which is not surprising as it has a really pungent mustard taste that I find not unpleasant. It forms a dense mat about 0.5m radius and about 10cm high with small leaves a little like carrot. The distinctive feature is the flowering stem which protrudes from the leaf stalks which are hairy and has multiple tiny bilobed seeds arranged in a linear fashion.






    History :

    Not much to report apart from it being used in Brazil as a traditional medicine for illnesses characterised by inflammation and pain. Cows that eat pasture with Coronopus apparently have tainted milk.

    Nutritional :

    Not much information but it would have flavonoids saponins tanins and mustard oils. No doubt other phytochemicals as well.


    Uses:

    The pungent raw leaves add real bite to salads and sandwiches or as a garnish. It can be cooked as a potherb. We have only nibbled on this weed when out in our yard. A chef into spicy foods would find this weed most interesting probably.

    Medical (pubmed) reports :

    1.An extract of Lesser swinecress was found to a have an anti-inflammatory effect in the mouse paw and pleural models ( the tissues are "irritated" by exposure to noxious chemicals and the effect of Coronopus was to reduce this inflammation).
    2.Another study used an extract of Coronopus in gamma irradiated mice- it was found to have a protective effect against radiation.
    3.Finally a study from 2005 showed that an extract of Coronopus had significant antiallergy antipyretic hypoglycemic and hepatoprotective effects.


    Conclusion:

    Another interesting edible weed that is usually overlooked and simply pulled out.

    Tom

    one of these photos is from google images this time as I was unable to get a good shot of the seeds (camera problems)

    orchard update

    Cleared (mowed) orchard.
    Spread sulphate of potash fertiliser pellets nutritech gold ( trace elements) around each fruit tree.
    Mulched with hay (the round bales we bought during the week).

    Ate some cumquat off the tree -they have become really sweet again after being quite sour last year -probably due to more diligent fertilising. Picked 1 papaya for further ripening inside to beat the possums/fruit bats.
    Almost ready - tamarillos and a bunch of bananas.
    Collected about 8 chokos from vine as well -such a prolific plant.

    Tropical peach and nectarine in blossom with lots of bees around them. The peach even has some small fruit already.

    Decommissioning a Swimming Pool

    We have a large inground swimming pool that is rarely used now that our children are grown and have left home. The pool has become a bit of a "bugbear" - requiring ongoing maintainence and expense that we would like to avoid. The pump for example probably uses upwards of $80/month of electricity.
    My solution has been this:

    Parts - 100 pvc stormwater pipe elbows and T fittings
    75x38 treated pine timber
    galvanised bugle head timber screws
    Roll of Bird Wire
    Heavy duty tarpaulin

    My pool shape is like a large clover so it made things difficult
    Using the PVC pipe a lattice was made - at about 900mm centres - lengths of pipe ("arms") were cut t sections inserted and elbows fitted at each end . These arms were then laid across 2 planks and when the right position was determined the length of the each leg was calculated using a measuring stick to the bottom of the pool. When these were fitted I also screwed the pine rails on to hold everything together before gently removing the planks to let it all settle into place. ( It took 2 times - the first I didn t lock it together enough and it all twisted fell over and sank! I actually didn t fit all the " feet" and rails before removing the planks)
    With the lattice in place it was simply a matter of attaching a few infill rails and a border of timber around the outside
    Completion was a layer of bird wire and a heavy duty tarpaulin to exclude any light. Pool pump is now turned off Anne doesn t need to clean the chlorinator anymore and we will reduce our electricity consumption.
    This leaves the pool in a state whereby it can be quickly recommissioned by someone down the track if we decide to move. We can also use this now as a rainwater tank with a bit more modification - inflow pipework etc.
    Cost: $1230

    Common Bittercress

    This is a small inconspicuous edible weed

    binomial name : Cardamine hirsuta
    common name : common bittercress splitting jenny or flickweed

    latin cardio - heart shaped and hirsuta- hairy - the first few leaves on the young plants are slightly hairy and heart shaped.
    The hairs are very indistinct on the plants here and I really cannot fathom why it would be called hairy. Also the heart shaped leaves are a bit of a stretch as well.

    Identification:

    This weed is of the mustard family and is quite common in the lawn at present (winter) in several areas but mainly where the grass has thinned out somewhat. It has pinnate leaves in a rough looking rosette and that also occur on the one or more flowering stems. It has distinctive seed pods about 2cm long that look like tiny pods of peas. These explode when touched if ripe thus spreading the seed. Height to about 15 cm on my property.

    History :

    Not specifically mentioned although Hammurabi from 2000 BC mentioned mustard as a medicinal drug.

    Nutritional :

    No information but undoubtedly has Vit A/carotenoids and Vit C and other phytochemicals that would be beneficial to us when eaten.

    Uses :

    It is not bitter in spite of the name and can be added to salads or stews - due to the small size the complete plant should be used by simply dicing up the stems leaves and seed pods.

    Medical : no reports relevant

    Garden - update




    Current projects - mulching and general tidying up especially near the root cellar and preparing two beds for sweet potatoes. Between these two beds I am going to erect a frame for growing Madagascar beans.

    Collected 2 round bales of mulching hay today after Garden Club Committee meeting - the cost was certainly right at only $10/bale. I have already spread 40 normal bales of sugar cane mulch past week that I collected from Jacobs Well area - this cost $4.50/bale.

    Pictures of current produce - our brassicas are doing really well with minimal caterpillar problems. We have lots of chicory radicchio lettuce carrots kale snow peas and beetroot almost ready as well. The cabbage in the picture is a sugarloaf.




    Also photo of Madagascar bean seeds - we have grown them for the first time this year on a fence near the vegetable patch but they really need something more "dedicated". We didn t get around to eating any of these beans so I hope the effort will be worthwhile.

    Thickhead

    Yet another edible weed that is also quite common here:

    binomial name : CRASSOCEPHALUM CREPIDIOIDES
    common name : Thickhead ebolo redflower ragleaf
    from Greek krasson = thick forceful kephale =head + Latin- crepido = fountain or base

    IDENTIFICATION:

    An erect or straggling annual herb with leaves that are soft drooping and alternate along the stem. The leaf shape is variable with new leaves generally elliptical and larger lower leaves lobed at the base. All leaves have toothed margins and are 20 x10cm approx.
    The plant grows about 1m high with a single stem for about 1/2m before dividing multiple times and has
    clusters of orange red flowers that mostly droop downwards. Seeds are dispersed by wind. Thickhead favours disturbed soils and is common in unkempt gardens (such as mine usually!)

    HISTORY and USES:

    Origin - from East Africa and Madagascar - seems to have reached Brisbane in the 1950 s. Stock - including poultry eat this plant
    Wildlife - native finches have been seen to be eating Crassocephalum seeds at the Kedron brook and no doubt this occurs elsewhere.
    Herbal uses : Kenya - indigestion a decotion for headaches. Uganda - leaves used on fresh wounds to help healing. Tanzania - leaves smoked for sleeping sickness.


    NUTRITIONAL:

    100gm - water 80gm energy 268 kJ (64 Cals) protein 3.2gm carbo 14gm fat 0.7gm Vit A 36 Total Phenols 183 ( Brussels sprouts ~250) mineral - Ca Fe Mn Na K Mg amino acids including threonine and tyrosine Vit C (122mg/100gm)

    warning:
    does contain pyrrolizidine alkaloids.

    WHAT TO EAT:

    top 2 young leaves in a salad or for boiling as a potherb
    The leaves are eaten in many parts of the world - it is quite aromatic and is often described as having a carrot like aroma and flavour.
    The raw leaves add a unique taste sensation to salads in moderation - the flavour is not reduced by boiling
    It is a commonly used herb in Africa especially in soups and stews
    In Nigeria it is lightly blanched excess water is drained off and the leaves are cooked with tomato onion and peppers

    PUBLISHED MEDICAL REPORTS:

    1. In a 2005 trial in Japan an extract of Thickhead had a potent anti-oxidant and protective effect on the liver in rats given carbon tetrachloride ( a liver toxin) - three strong free radical scavenging chemicals were identified including quercertin.
    2. A different species of Thickhead has been shown to have anti- inflammatory effects - blocking the Cox pathways that is also used medically by such drugs as Celebrex.
    3. An extract of Thickhead has been shown to exhibit anti- mutagenic activity - ie against cancer cells forming - but less than Solanum nigrum.
    4. Thickhead extract has exhibited significant blocking action against Tumour necrosis factor Cox 1&2 and other inflammatory pathway.
    5. Similarly an extract has shown inhibition of melanoma in a mouse model.

    CONCLUSION:

    It certainly has a strong flavour - but not unpleasant.
    Try a few small young leaves in a salad or as a garnish.
    Boil a few leaves amongst other greens such as silverbeet or spinach but don t eat too often in view of the report of the pyrrolizidine alkaloids.

    fruit trees planted today

    Here s details of the fruit trees we bought from Forbidden Fruits Nursery and planted today

    1. Wampi : Clausena lansium

    tall slender tree with large lobed bright green leaves that are aromatic when crushed. Sprays of white flowers that develop into brown fruits that have a grape like greenish flesh which is high in Vitamin C

    2. Star Apple : Chrysophyllum cainito

    round fruit with shiny green or purple skin. The flesh is white tinged with purple and divided into segments by shiny dark brown seeds. Flesh is soft sweet and juicy

    3. Hill Gooseberry : Rhodomyrtus tomentosa

    Evergreen tree to 3m with masses fo pink flowers. Produces many small sweet purple/green edible berries.

    4.
    Soursop: Annona muricata

    Semideciduous tree. Large fruits with slightly acidic white juicy pulp

    5. Natal Plum Carissa macrocarpa

    Bush to 2.5m perfumed flowers and delicious red fruit

    6. Cherry of the Rio Grande: Eugenia aggregata

    Small tree with glossy green and waxy leaves to 3-4 m White flowers followed by deep purple plum sized fruit that has a sweet cherry flavour

    7.
    Quince Cydinia oblonga (smyrna variety)

    Deciduous tree with large green leaves and large pale yellow fruit. As we are ex Kiwis we like this fruit from our childhood days and have sometimes managed to buy it in Brisbane from growers in the Stanthorpe area. The fruit needs to be cooked.

    8.
    Thornless Blackberry : Rubis canadensis

    Planted in a specially prepared berry patch beside our raspberry and (yet to be planted) blueberry

    also planted was a Pomegranate
    :Punica granatium

    Some of these trees will be fruit fly prone and will need netting when the time arrives for that.

    Incidentally our tropical peach is bursting out in blossom and some fruit is already developing so I will be netting that in the next week or so after most of the blossom has dropped and the fruit has set.

    Commelina diffusa


    Here s another edible weed on our property:


    Binomial name : COMMELINA DIFFUSA
    common names: wandering jew or scurvy weed
    Commelina = prussian blue of the flower diffusa = spreading

    Identification:

    Commelina is a slender and brittle trailing plant -the stems are easily broken.
    It has green pointed leaves and bears small blue flowers with three rounded petals. It roots readily from nodes and broken off pieces .
    There are other commelina sp in Australia but the above seems to be the commonest around Brisbane.

    This is a common "weed" on our property - it is a native to south east Queensland and elsewhere. Look alikes are : Tradescantia flumenensis and Commelina benghalensis. Trad flumenensis has a white flower and is thus readily identified. Commelina benghalensis is also called Hairy Commelina -it has brown hairs on the stem and larger leaves than the native species.
    It occurs where the forest canopy is disturbed and declines when the bush canopy becomes mature. It recently "took off" on a portion of our property when we removed some Casaurina.

    History and Uses:

    In China CD is used for fevers and as a diuretic . A dye is also obtained from the flowers for use in painting.
    There is no evidence it was eaten by the Aborigines. Captain Cook supposedly gave it to his crew to help prevent scurvy.
    As a ground cover it provides shelter for small lizards frogs and native bees are attracted to the flowers. The early settlers also ate this weed to prevent scurvy - hence the name scurvy weed.

    Nutritional:

    The common name suggests one component which is of course Vit C - about 40mg/100gm ( an orange is about 55 mg/100gm or about 70mg /fruit)
    The moisture content is quite high at about 88% and it has about 5% carbohydrates (ie a few kilojoules of energy)
    It also contains some niacin and riboflavin in modest amounts
    Thus as it contains Vit C and B vitamins it will have a useful anti- oxidant effects.


    What parts to eat:

    Terminal leaves and flowers in a salad or cooked as an ingredient in boiled leafy vegetables.

    Published Medical reports :

    CD extract has been reported to exhibit antimicrobial and anti-inflammatory activity in vitro.
    Another study indicates that an extract of CD has antifungal activity . This study also demonstrated an anti-oxidant effect.

    Conclusion:

    Taste wise it is unremarkable when mixed with other salad items but the blue flowers do add a touch of colour.
    Medically - safe to eat - modest Vit C and other vitamins . Probably useful anti-oxidant and anti-inflammatory activity.
    No warnings apparent.

    Club visit to Byron Bay area

    Garden club visit to Byron Bay:

    We had a great weekend away with about 20 people from our garden club -Tamborine Sustainable Gardeners Society.

    The start was at the Mullimimby Community Garden where we were shown around by Jeanette. The community garden is relatively new and is a place where locals can grow food learn from others about gardening social network and participate in developing a sense of community. Right beside there was a local market which was also excellent with lots of stalls of local produce organic type products foods etc. This small town is well placed for a sustainable future with good soil good rainfall and climate.

    Treatment of Leukemia

    By leukaemia

     

    Treatment of Leukemia

    A common white flower could revolutionize the treatment of leukemia and save thousands of lives scientists have claimed. 


    An extract from the white flower commonly known as Baby s Breath can boost the efficiency of anti-cancer drugs by a million times according to experts. They found that molecules called saponins extracted from the Gypsophila paniculata plant appear to break down the membrane of cancer cells .This makes it much easier for antibody-based drugs known as immunotoxins to attack the cancerous cells. As a result immunotherapy used to treat certain types of leukaemia and lymphoma is increased in potency by over one million-fold . The discovery has been made by scientists working for the charity Leukaemia Busters based in Southampton Hants.


    The charity is run by David and Bee Flavell whose son Simon Flavell died with an incurable form of childhood leukaemia in 1990 aged ten. Scientists carried out the work at the newly refurbished Simon Flavell Leukaemia Research Laboratory at Southampton General Hospital. Dr David Flavell said: "I am usually careful about the words I use with things like this but this discovery could truly revolutionise the way these antibody-based drugs work and it will save lives. "And this doesn t just apply to leukaemia there is a really big possibility this can be used for many cancers too. "This is a potentially very important discovery that could allow us to kill leukaemia cells in the patient much more effectively with much lower doses of immunotoxin. 
    "The challenge now is to establish how best to apply this laboratory discovery to the treatment of patients. "We are all excited at the major advance this could represent for immunotoxin treatments for leukaemia." The next step is to take the findings from the test tube and into clinical trials to turn it into a treatment that can be made available to patients. If that is successful - a process that could take between three to five years - then thousands of leukaemia patients could benefit from lower doses of drugs. 
    The breakthrough has come as a result of 12 months of research and testing in collaboration with scientists based in the German capital Berlin. Dr Flavell added: "We still need to do laboratory-based work to further develop this discovery into a practical and safe treatment for patients and money is the key to achieving this. "Leukaemia Busters scientists and doctors have worked tirelessly day and night over many years and have relied on the generosity of donations to fund a great deal of its work. The name Leukaemia Busters and its logo were both devised by Simon Flavell before he died. The youngster was a great fan of Ghost Busters.
