Herbal
Menopause Remedies Ineffective
Recent media headlines state, "Except for an herbal remedy developed by American
Indians, most of the exotic berries, teas, herbs and oils frequently taken by
women to ease menopause symptoms have been ineffective in clinical trials."
If the health concerns of women were the main interest of the research, the media
would have written headlines that state, "Researchers at Columbia University
and George Washington University have found a safe and effective alternative
to synthetic drugs." Researchers examined the results of 29 independent studies
on alternative treatments for hot flashes and found excellent support for the
effectiveness of the herb Black cohosh.
Women are rightly fearful of synthetic hormone replacement therapy (HRT) since
Government scientists at the National Institutes of Health abruptly halted the
nation's biggest study on HRT in July 2002, saying long-term use of synthetic
estrogen and progestin drugs increase a women's risk of breast cancer by 26%,
her risk of a heart attack by 29%, and her risk of stroke by 41% (SOURCE: JAMA.
2002;288:321-333).
Black cohosh
Black cohosh, a member of the buttercup family, is among the most popular of
alternative treatments for menopause. Most clinical studies involved a concentrated
brand called Remifemin, manufactured and sold as a natural prescription drug
in Germany since the mid 1900's, first by Schaper and Brummer (GmbH) and more
recently by GlaxoSmithKline. Black cohosh has been used safely and effectively
in Germany for almost 50 years with no evidence of any serious side effects,
contraindications, or drug interactions.
Benefits
In several clinical trials, Black cohosh has been shown to provide significant
improvement in 86% of all patients within 4 weeks of onset of therapy. Studies
show that Black cohosh reduces menopausal symptoms of hot flashes, perspiration,
headache, vertigo, heart palpitations, ringing in the ears, nervousness, irritability,
sleep disturbances, weariness, and depressive moodiness, while increasing motivation
and emotional stability. A recent study also suggests that black cohosh may protect
animals from osteoporosis (Phytomed 1996/7;3:379-85). Human studies have not
confirmed this action.
How
much is needed?
The recommended amount is 20-40 mg twice per day. The best-researched extract
provides 1 mg of deoxyactein per 20 mg of extract.
Side
effects
Very large amounts (over several thousand milligrams daily) of this herb may
cause abdominal pain, nausea, headaches, and dizziness. In large scale clinical
trials, none of the patients in clinical trials receiving Remifemin discontinued
taking the supplement due to side effects. There are no known drug interactions
with Black cohosh. Black cohosh is considered to be similar to Estriol, the
healthy, protective estrogen, because it acts as a weak or partial antagonist
to Estradiol (which is associated with increased risk of breast, ovarian, and
endometrial cancer). Black cohosh is not recommended for pregnant or breast-feeding
women due to lack of clinical studies on these women.
