Herbs
have a longer history of use than any other form of medicine, and
more than 25% of existing medicinal drugs are extracted from, or have
originated from, plant materials. Up to three-quarters of medicines
taken globally are herbal representing a vast collective of information,
which is now attracting substantial research.
It should be remembered that just because
a product is considered natural, this does not automatically make
it safe. Herbs can have side effects, contraindications, and potential
interactions with orthodox medicines or nutritional supplements.
They are a potent form of medicine and should be used with practitioner
guidance to ensure both safety and maximum therapeutic benefit.
Recent studies demonstrate that
St Johns Wort can be significantly
more effective than Prozac in major depressive disorder
(Fava, et al, 2005)
Side effects of St Johns Wort
are at least ten-fold lower than recorded with synthetic antidepressants
(Schulz, 2006)
Combining Black Cohosh and St Johns
Wort is significantly superior to placebo in alleviating
menopausal symptoms and depression (Uebelhack, 2006)
A review of 19 studies states that
Black Cohosh extracts appear to ease menopausal symptoms
(Low Dog, 2005)
Single doses of Gingko biloba improved
performance in tests of attention and memory in
healthy young volunteers, but six week courses had no effect suggesting
that tolerance develops in young,
healthy adults (Elsabagh, et al, 2005)
Six week courses of Gingko benefited
mental flexibility in late stage menopausal women
who had previously performed poorly (Elsabagh, 2005)
However results of studies are often
inconsistent, indicating the need for further study. This may be
partly because western medicine does not take sufficient account
of the individuality of the patient. Traditional medicine assesses
each person, and the addition of these diagnostic skills enables
the practitioner to choose the most effective herb for the person,
rather than prescribing for the condition.
We utilise both Western herbs and the
Three Treasures range of Chinese medicine patent remedies. Assessment,
and choice of herbal remedy, is made by clinical history, physical
examination, the traditional methods of tongue and pulse diagnosis,
and the most recent western knowledge.
