"I think it is better to use a natural product [saw palmetto] rather than something cooked up in a chemical lab."

I disagree. In the U.S., so-called "natural" herbals have been tested and found to contain lead, pesticides, contaminating additional herbs and/or pharmaceuticals (some of them banned). Some of them don't contain the herbs they are supposed to contain.

I specify "in the U.S." because here the lack of testing, purity and certification of so-call herbals and dietary supplements is a damn shame.

"Natural" is not a protection. There are natural things that can make you miserable, destroy your health or kill you. American Poison Control centers have handled thousands of poisonings involving so-called natural or herbal dietary supplements.
