There are a stack of threads on this site where users have experienced nasty side effects from saw palmetto. Here is just one for example:

Many stores sell supplements containing saw palmetto. I would avoid these products at all costs.
Some supplements also have a hidden ‘proprietary blend’ where the ingredients are not listed.
Avoid these supplements … chances are that the proprietary blend will include saw palmetto.
Many supplement suppliers claim that saw palmetto helps to ‘nourish’ , ‘protect’ the prostate etc, but
if you research this site you will see for yourself the true damage that saw palmetto can cause.
