Fo-Ti the longevity herb
The Chinese have been practising longevity medicine for thousands of
years and now their secret's out. The root of the Polygonum multiflorum
evergreen known to the Chinese as He-shou-wu and commonly known as Fo-ti
has always been highly regarded in the Far East as an aphrodisiac. However
research is showing that not only does Fo-ti increase the quality of life
but it combats infertility, fatigue, atherosclerosis, high cholesterol,
immune disorders and even slows the aging process.
Look younger and live longer with Fo-ti
Historically Fo-ti has been used to fight infertility and prolong the
quality and length of life itself. Indeed its Chinese common name He-shou-wu
is said to have been the name of a Tang Dynasty man whose infertility
was cured by the herb and according to tradition his unusually long life
and libido was attributed to its anti-aging effects. Fo-ti has often been
compared to Ginseng but unlike its cousin has not been subject to rigorous
experimental study in humans. However we do know that it contains active
substances called anthroquinones such as chrysophanic acid, rhein and
emodin thought to be responsible for its vasodilatory and immunosuppressive
effects. Phospholipids like lecithin and tannins have also been identified
in high amounts which are well known for their fat emulsifying, cholesterol
lowering and cardiotonic actions. It has also been established that the
anthraquinone glycosides rhein and emodin act to stimulate bowel movements
and are most likely responsible for its laxative effect. The pro-longevity
action of these anthroquinones is thought to be a combined result of their
augmentation of cellular immunity and growth of blood cells, alleviation
of atherosclerosis (hardening of the arteries), high blood pressure and
cholesterol and their long term regulation of blood sugar.1 All this is
good news for those fighting the effects of aging but more and more mature
and healthy men and women are cashing in on the herb's cosmetic enhancements
by restoring colour to greying hair, moistening the skin which reduces
wrinkles and even improving the condition of their teeth. Senior citizens
too can profit from Fo-ti's rejuvenating and mobility-increasing action
because it nourishes the joints in particular sinew and cartilage. Even
where illness or old age is not a problem Fo-ti is effective as a preventative
for common ailments like constipation and even as a flu remedy.
Herbal Viagra?
Fo-ti's effects on sexual disorders are well established. Its enhancement
of libido in both sexes has made Fo-ti a household name in China for thousands
of years. Couples can benefit from its pro-sexual effects where poor libido
or even genital dysfunction is suspected. Certainly its aphrodisiacal
properties have been verified again and again in scientific studies which
have proven its ability to combat erectile dysfunction in males by dilating
capillaries, increasing micro-circulation and hence blood supply to the
penis whilst preventing premature ejaculation very much like the Viagra
drug. But its action on the sexual glands is not confined to men because
Fo-ti exerts a direct action in the pleasure centres of the brain and
vasodilatory effect on the genitals in both sexes increasing arousal in
the short term and inducing endocrine changes which improve fertility
in the longer term. Furthermore it also seems lubricate the vagina thus
protecting against infection, discharges and dryness.
Healthy Hearts and Minds
Health professionals are increasingly turning to Fo-ti to treat neuropsychiatric
disorders because of its buffering effects on stress. It is indicated
for a plethora of nervous and metabolic illnesses like adrenal insufficiency,
neurasthenia (nervous exhaustion or weakness), symptoms of dizziness or
insomnia, nerve injuries such as sciatica and even psychiatric conditions
like split personality.2 Recently it has featured in the 3rd edition of
the Life Extension Foundation's "Disease Prevention and Treatment"
guide as an adjunct to drug therapy protocols in Parkinson's disease because
of its ability to stimulate the production of the brains "pleasure
transmitter" dopamine. This brain chemical is grossly deficient in
Parkinson's disease and may well be implicated in deficient libido too
given Fo-ti's pro-sexual action in the sexually disinterested. Dopamine
is essential for the proper arousal and motivation to face new learning
situations and without it we suffer from depression and an inability to
handle stress. Fortunately Fo-ti also improves adrenal response to stress
by regulating the turnover of the stress hormones adrenaline and noradrenalin.
All of this goes a long way to explaining how the herb combats nervous
exhaustion. It also has a proven track record as a natural sedative for
insomnia.1 and to this end seems to behave as an adaptogen by stimulating
activity where it is lacking and tranquillizing where it is in excess.
But it is its medicinal action in cardiovascular health that has attracted
most recent attention. Fo-ti whole root has been shown to lower serum
cholesterol levels, according to animal and human research, as well as
to decrease hardening of the arteries or atherosclerosis.3, 4. Studies
on mice have shown that it inhibits blood triglycerides and has an ability
to reduce enlarged "fatty" livers such as that occurring in
cirrhosis .5 What's more it has been shown to have efficacy as a vasodilator
against hypertension, angina pectoris and even lowers the incidence of
coronary heart disease.
Preliminary research in the West suggests that fo-ti also plays a role
in a strong immune system and has antibacterial action against many infectious
agents like mycobacterium tuberculosis (TB) and shigella flexneri. It
has even been used successfully in cases of malaria.6 Furthermore the
two laxative agents in Fo-ti - emodin and rhein - have shown promising
anti-tumour and anti-cancer activity as well. More recently researchers
have isolated a flavinoid called catachin (also found in green tea notorious
for its life extension properties) that has powerful anti-tumour and antioxidant
effects and which may account for Fo-ti's anti-aging reputation.
The net effect of Fo-ti use is complex but appears to supply a mild depressant
action to the immune and cardiovascular responses whilst invigorating
the mind and libido, and this makes it a popular choice among cheeky elderly
folk. With its myriad benefits on mental, cardiovascular and gerontological
health Fo-ti certainly seems to be a tonic for poor condition both inside
and out for the young or old. Unfortunately there is a dearth of human
clinical trials to support these contentions at present but in the face
of overwhelming supporting anecdoctal and historical data Fo-Ti has already
secured its place as an important revitalizer and aphrodisiac among the
performance conscious.
How to take it
Fo-ti is widely available in health food stores and apothecaries and
usually comes as processed powdered root from which a tea can be made
by boiling 3-5 grams in a cup of water for 10-15 minutes. Three or more
cups of this should be drunk each day until improvements in vigour are
noticed. If you cannot tolerate the taste capsules containing 500mg of
the powered herb are widely available and doctors may suggest taking five
of these three times per day.7 Fo-Ti root herbal extracts are usually
standardised for 10% chrysophanics and 1.9% reveratrol and come in tablets
or capsules of varying strengths. The unprocessed roots may cause mild
diarrhoea and taking more than 15g may cause numbness in the arms and
legs. At the time of writing there are no known drug interactions
