Saw Palmetto and PCOS
Saw palmetto (also know as sabal palmetto) is a reddish brown-to-black berry growing on a 6'-8" palm tree (Serenoa repens). The fruit of this palm have been part of the diet of natives of the southeastern U.S. for hundreds of years.
It is widely used for the treatment of enlarged prostate glands in men. It is thought that prostate glands become enlarged primarily because of a metabolite of testosterone, called dihydrotestosterone, or DHT. Women with PCOS (polycystic ovarian syndrome) also tend to have higher levels of testosterone and DHT than other women. Therefore, what works for men may work for women.
How does it work in women?
One of the most troubling symptoms of women with PCOS is hirsutism (too much hair, in the wrong places). Hirsutism is thought to be mostly due to excessive levels of androgenic hormones. Examples of androgens are testosterone, androstenedione, and DHEA.
Testosterone is the main androgen were concerned about. Its normal for men to have a lot of testosterone and for women to have some. In both men and women, testosterone is converted into a more potent hormone called DHT (dihydrotestosterone). DHT is the hormone in your skin that stimulates hirsutism, which is male pattern hair growth. If you can reduce DHT, you may be able to reduce hirsutism (hair growing where you don't want it) or male pattern hair loss (restoring hair where you do want it).
Saw palmetto appears to reduce DHT in three different ways:
* Inhibits DHT production;
* Inhibits the binding of DHT to its cell receptors;
* Promotes the breakdown of DHT.
Testosterone is converted into DHT by an enzyme called 5-alpha-reductase. 5-alpha-reductase is inhibited by saw palmetto, and thus less DHT is produced and hirsutism may be reduced.
Saw palmetto may be helpful in another way. A high level of estrogen may inhibit the elimination of DHT. Some women with PCOS have estrogen levels that are too high. It is reported to have an anti-estrogenic effect, thus helping with the removal of DHT.
There have been many studies of men with testosterone disorders that demonstrate the effectiveness and safety of saw palmetto. There arent yet any studies of hirsute PCOS women. However, naturopathic physicians using these herbs for PCOS are seeing consistently favorable results.
Because of possible hormonal activity, it is not recommended for women who are pregnant or breast-feeding.
