Cultivation:
Requires a very well-drained soil and a sunny position. Plants are only hardy on the south coast of England, where they succeed from Torbay westwards. A monocarpic species, the plant lives for a number of years without flowering but dies once it does flower. However, it normally produces plenty of suckers during its life and these take about 10 – 15 years in a warm climate, considerably longer in colder ones, before flowering. This plant is widely used by the native people in its wild habitat, it has a wide range of uses. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – surface sow in a light position, April in a warm greenhouse. The seed usually germinates in 1 – 3 months at 20°c. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle and grow them on in a sunny position in the greenhouse until they are at least 20cm tall. Plant out in late spring or early summer, after the last expected frosts, and give some protection from the cold for at least their first few winters. Offsets can be potted up at any time they are available. Keep in a warm greenhouse until they are well established


Edible Parts:
Leaves; Root; Sap; Seed; Stem.

Edible Uses: Drink.You
The heart of the plant is very rich in saccharine matter and can be eaten when baked. Sweet and delicious, but rather fibrous. It is partly below ground. Can be dried for future use or soaked in water to produce a flavourful beverage. Seed – ground into a flour. Flower stalk – roasted. Root – cooked. Sap from the cut flowering stems is used as a syrup. The sap can also be tapped by boring a hole into the middle of the plant at the base of the flowering stem. It can be fermented into ‘Mescal’, a very potent alcoholic drink.

Medicinal Actions & Uses:-
Antiseptic; Diuretic; Laxative.

The sap is antiseptic, diuretic and laxative.

Disclaimer:The information presented herein is intended for educational purposes only. Individual results may vary, and before using any supplements, it is always advisable to consult with your own health care provider.

Other Uses
Brush; Fibre; Miscellany; Needles; Paper; Pins; Soap; Thatching.

The leaves contain saponins and an extract of them can be used as a soap. It is best obtained by chopping up the leaves and then simmering them in water – do not boil for too long or this will start to break down the saponins. A very strong fibre obtained from the leaves is used for making rope, coarse fabrics etc. To make hair brushes and brushes for cleaning, the dried matter of a dead and rotten leaf was knocked free from the fibres, which were then bent in two. the upper end of this brush was wrapped with a cord and the bent portion was covered with a cloth. The loose fibres were cut to the right length and hardened by burning the ends. A paper can also be made from the fibre in the leaves. The thorns on the leaves are used as pins and needles. The dried flowering stems are used as a waterproof thatch and as a razor strop.

Green Tea May Help Reduce Risk of Certain Cancers

[amazon_link asins=’B00DE4NPV0,B003D4F2US,B01G0S3Y44,B0042IMPTU,B000GG0BNE,B00PFDH0IC,B000WB1YSE,B0016BFR4G,B0017T2MWW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ebebe9be-5c8d-11e7-ae93-dd4a39e89aff’]

Researchers in Japan have said drinking green tea may be an important health resource to reduce the risk of developing certain types of cancer.

The study appearing in the American Journal of Epidemiology suggests drinking five or more cups of the antioxidant-rich beverage can reduce the risk of developing blood cancer by 42 percent. The same amount of green tea was also associated with a 48 percent lower risk of lymph system cancer, according to Reuters.

Researchers followed 19,749 men and 22,012 women with no previous history of cancer over a period of nine years for the study.

WebMD notes that previous research has linked the tea to fighting heart disease, lowering cholesterol and preventing diabetes and dementia.

“Taken altogether, the evidence certainly suggests that incorporating at least a few cups of green tea every day will positively affect your health. It’s not going to cure anything and it shouldn’t be consumed as a drug, but it can complement the rest of the diet,” Tufts University scientist Dr. Diane McKay tells WebMD.

Researchers involved with this study say further work is needed to confirm the health benefits of drinking green tea, and to determine whether daily consumption might prevent certain cancers.

Mediterranean Diet Cuts the Risk of Depression by 30%

Consuming plenty of olive oil, nuts, fruit and vegetables – like those living in warm countries by the Med – means you’re less likely to be hit by the blues, according to researchers.

A study of 10,000 people found that those who ate these foods most regularly were found to be have a much sunnier outlook on life.

The diet traditionally favoured by natives of countries such as Greece, Spain and Italy is high in unsaturated fatty acids and antioxidants. It is also low in red meat and dairy products while alcohol, particularly red wine, is encouraged – but in moderation.

Sunshine food: Regularly consuming, nuts, fish, fruit and vegetables – like those living in warm countries by the Med – can cut the risk of depression by 30 percent

A Mediterranean diet is already thought to improve heart health and stave off cancer.
Dieticians believe it appears to improve the flexibility of cells lining the walls of blood vessels, particularly in the heart and circulatory system.
The latest study was inspired by the lower risk of suffering mental disorders in Mediterranean countries than in Northern Europe.
Dr Almudena Sanchez-Villegas and colleagues studied 10,094 healthy Spanish men and women between 1999 and 2005. For the project, they filled in food diaries and their adherence to a Mediterranean diet was checked on nine main points.
These included frequency of consumption of mono-unsaturated fatty acids, moderate intake of alcohol and dairy products, and low intake of meat. High intakes of fruit, nuts, cereals, vegetables and fish were also important.

The Mediterranean diet is high in unsaturated fatty acids and antioxidants. Wine is encouraged, but in moderation
After more than four years of follow-ups, there were 480 new cases of depression, 156 in men and 324 in women.
Those who followed the Mediterranean diet most closely had a greater than 30 per cent reduction in the risk of depression compared with those who had lowest scores.

The figures did not change even when adjusted for other markers of a healthy lifestyle, such as being married, said a report in the Archives of General Psychiatry.
Dr Sanchez-Villegas admitted: ‘The specific mechanisms by which a better adherence to the Mediterranean diet could help to prevent the occurrence of depression are not well-known.’

However, the diet is known to keep arteries healthy, fight inflammation and repair cell damage, she said.
‘The role of the overall dietary pattern may be more important than the effect of single components,’ added the academic, of the University of Las Palmas de Gran Canaria and University of Navarra.

There may be ‘a fair degree of protection’ from the combination of the omega-3 fatty acids found in fish with other natural ingredients in olive oil, nuts, fruit and plant foods.

Last year, U.S. researchers found strict adherence to a Mediterranean diet could help stave off Alzheimer’s and premature death.
A team from the UK, Greece and Spain also found it helped prevent the development of asthma and respiratory allergies in children.
Other research shows taking fish oil every day in pregnancy can cut the risk of post-natal depression.

Extend Your Life Span with this Antioxidant

[amazon_link asins=’B00LPW9X32,B01N3746GJ,B01CD3UVAK,B002G75WZI,B01N3LZY3O,B0727KR2X6,B01GS6Q300,B003Q8SAZU,B005JAT50C’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’5174151b-5758-11e7-897d-754ae1d70843′]

In 2003, research showed that resveratrol, a powerful polyphenol and anti-fungal chemical, was able to increase the lifespan of yeast cells. The results ignited flames of hope for an anti-aging pill. According to the findings, resveratrol could activate a gene called sirtuin1, which is also activated during calorie restriction in various species.
Since then studies in nematode worms, fruit flies, fish, and mice have linked resveratrol to longer lives. Other studies with only resveratrol have reported anti-cancer effects, anti-inflammatory effects, cardiovascular benefits, anti-diabetes potential, energy endurance enhancement, and protection against Alzheimer’s.

Resveratrol is found in grapes and red wine, and has particularly been associated with the so-called ‘French Paradox‘ — the low incidence of heart disease and obesity among the French, despite their relatively high-calorie diet and levels of wine consumption.
