Spearmint Tea May Reduce Hirsutism in PCOS
Researchers at the
Suleyman Demirel University Medical School in Isparta, Turkey had been
receiving "major complaints" from the local men that drinking mint
tea was interfering with their libido and reproductive function.
To find out what
might have been the problem, the medical school added peppermint to the
drinking water of rats. The rats drinking the peppermint had a significant
reduction in their testosterone and an increase in follicle stimulating hormone
(FSH) and luteinizing hormone (LH).
Bear in mind that
elevated testosterone and disordered FSH and LH levels are primary sources of
difficulty for women with polycystic ovary syndrome.
Just recently, the
medical school completed a study of 21 women who had excessive hairiness.
Twelve of them had PCOS and the other 9 had hirsutism of unknown origin.
The women took a
cup of spearmint tea twice a day for 5 days in the follicular phase (first
half) of their menstrual cycles. The tea was made by pouring boiling water on
1-2 teaspoons of dried spearmint and leaving it for 5-10 minutes, then
straining and drinking the tea.
After treatment
with the spearmint tea, the women had a significant decrease in free
testosterone and increase in LH, FSH and estradiol hormones. There were no
significant decreases in total testosterone.
The distinction
between "free" and "total" testosterone is important.
Testosterone hormone is either bound to a carrier protein, or it is not. The
unbound testosterone is biologically active while the bound hormone is not
active. "Total" testosterone includes both bound and unbound hormone.
The interesting
point about this study is that the spearmint tea reduced the "free",
biologically active testosterone. It is the free testosterone that contributes
to hirsutism, acne and other PCOS problems. If free testosterone can be
reduced, the symptoms will tend to diminish.
The researchers
state that "spearmint can be an alternative to antiandrogenic treatment
for mild hirsutism."
Although we
haven’t yet seen the details of these studies, it wouldn’t hurt to drink
spearmint or peppermint herbal teas to see if they have any beneficial effect
on your symptoms.
