Saw Palmetto has been used for years as a way to treat benign hyperplasia of the prostrate. Increased DHT levels will increase prostatic tissue and a natural cure has been sought after. The same DHT is associated with minaturization of hair follicles in male pattern baldness. Testosterone converts to DHT and saw palmetto has claims of acting as a DHT blocker. But is there any evidence to support such claims?
Can saw palmetto act as a DHT blocker?
There are several studies that show that Saw Palmetto has no efficacy at all for benign prostatic hyperplasia.
"In a double-blind trial, we randomly assigned 225 men over the age of 49 years who had moderate-to-severe symptoms of benign prostatic hyperplasia to one year of treatment with saw palmetto extract (160 mg twice a day) or placebo. "
"In this study, saw palmetto did not improve symptoms or objective measures of benign prostatic hyperplasia. (ClinicalTrials.gov number, NCT00037154.)."
Another study for prostatitis showed:
CP/CPPS treated with saw palmetto had no appreciable long-term improvement. In contrast, patients treated with finasteride had significant and durable improvement in all various parameters except voiding.
However in contrast to BPH there are a few studies that show that Saw Palmetto
has shown an increase on hair growth.
"Saw palmetto (Serenoa repens) has been used as a natural treatment for androgenetic alopecia and has a similar mechanism . Review Novel agents for the treatment of alopecia."
Semin Cutan Med Surg. 1998 Dec; 17(4):276-83.
"Interestingly, in a recent study, it was found that 38% of males with AGA which received Serenoa repens at 320 mg every day for 24 months showed increased hair growth. The authors concluded that it could be used as an alternative treatment for mild to moderate AGA and that it is more effective than finasteride in this respect . "

A third study showed that Saw Palmetto plus Pumpkin Seed had some synergistic effects on BPH.
"IPSSs in groups B, C and D were significantly reduced (P < 0.05) after 3 months of treatment (Table 2). IPSS of group B was decreased by 12.0 points (58.0% change), from 20.7 to 8.7 after 12-month treatment. IPSS of group C was also decreased by 9.2 points (50.3% change), from 18.2 to 9.1. The average IPSS of group D showed a constant decline from the beginning (19.0) to the end of the 12-month treatment (4.7) by 14.3 points, indicating 75.3% improvement in voiding symptoms. In particular, BPH status of group D was improved from moderate (8~19) to mild (≤7) according to IPSS. The reduction of IPSS after 12 month treatment was highest in group D, however, there was no significant difference among the groups."
