Saw Palmetto is best known for its use in decreasing symptoms of an enlarged prostate (benign prostatic hypertrophy, BPH). Saw Palmetto is used for treating certain types of prostate infections. It is also used sometimes with other herbs to treat prostate cancer.
Some people use Saw Palmetto for colds and coughs, sore throat, asthma, chronic bronchitis, chronic pelvis pain syndrome, and migraine headaches. It is also used to increase urine flow (as a diuretic), to promote relaxation (as a sedative), to enhance sexual drive, and to promote hair growth.
