Herbs to Prevent Breast
Cancer, Heart Disease and Menopausal Symptoms
"Red clover dietary supplements are sold as a phyto 'plant]estrogen
source and a 'natural' form of 'Hormone Replacement Therapy.]" So wrote
Dr. Fugh-Berman and F. Kronenberg in the journal Menopause, vol. 8,
2001. That certainly perked our interest, not only because of our search
for plant sources for menopausal problems but also because we knew Dr.
Fugh-Berman when we were researching Tamoxifen for a major publication.
We disagreed, by the way, but still feel that she is one of the better
physicians around.
We still respect her,
but her report notes some studies that she admits are invalid for
various reasons. We usually prefer to cite studies that are valid and
helpful for our readers.
So we did our own
researching and collected reports from the following:
Chemical Res. Toxical.
Atherosclerosis
Nutr. Metab. Cardiovasc. Dis.
Ann. Ital. Med. Int.
J. of Agric. Food Chem.
J. of Clin. Endocrinol. Metab.
Proc. Soc. Exp. Biol. Med.
One report observed
that there were plants that affected estrogen receptors (ER) in the
breast and those that affected progesterone receptors (PR), some having
effects that promoted and others that discouraged cancer cell growth.
"The highest
estrogen-receptor-binding herbs that are commonly consumed were soy,
licorice, red clover, thyme, tumeric, hops, and verbena.....In general,
we found that ER-binding herbal extracts were agonists 'inducers], much
like estradiol, whereas PR-binding extracts were neutral or
antagonists."
We should explain here
that the principle behind the anti-cancer drug Tamoxifen as well as
estrogen-binding plants is that they occupy the estrogen receptor, thus
preventing the activity of the woman's own estrogen and thereby reducing
the risk of breast cancer.
We concluded from the
report that the PR-binding plants were safer than the ER, though both
had anti-cancer effects. PR-binders included oregano, verbena, turmeric,
thyme, red clover and damiana.
Another study, this
time of cardiovascular risk, was done on women measuring the elasticity
of their large arteries 'a good test of risk] before and after taking
red clover. They observed that there...."was significant... improve'ment]
with red clover isoflavones 'ingredients.]"
Another report,
evaluating plant extracts for the potential treatment of menopausal
symptoms, found that red clover, chasteberry and hops had potentially
the strongest effects of the plants tested. The scientists were
surprised, as were we, that the ingredient with the most potent effect
was genistein in the red clover. This is a factor present in soy as
well.
