The Evidence
There has been a number of scientific trials of saw palmetto for treating an enlarged prostate. Findings show that using saw palmetto relieves many of the symptoms of enlarged prostate including nighttime urination, frequent urination and overall quality of life.Saw palmetto has also been proposed to treat other health problems. The evidence for these treatments is not as good. These treatments include male-pattern baldness and hair loss and underactive bladder. The limited studies available are inconclusive about these two applications of saw palmetto.
The herb has also been proposed to treat prostatitis though this evidence suggests that saw palmetto does not work for this condition.
