Saw palmetto, also known as sabal or Serenoa repens, is a plant native to the southeastern part of North America. It has been valued for centuries as a food source and for medical purposes, such as its ability to act as a sedative and a tonic. As with any homeopathic remedy or pharmaceutical drug, saw palmetto side effects may exist. For example, it may increase the chance of bleeding, which could be detrimental for people with hemophilia or other blood clotting disorders.

As a homeopathic remedy, most practitioners consider saw palmetto to be relatively safe. Saw palmetto side effects are typically mild. Some people who have used the plant for medical purposes have claimed that it caused dizziness, constipation, nausea, diarrhea, headaches, and vomiting. There have been reports that it causes impotence in men, although the reports have not been scientifically proven. In fact, many of the saw palmetto side effects occurred in equal numbers as experienced by people who consumed a placebo or sugar pill.

How long does it take for saw palmetto to damage the liver?

I don't think it would cause such serious damage if it's taken for a short term right?

I took saw palmetto for my prostate for three months, but I only took a 300mg capsule several times a week.

I actually have several other family members and acquaintances who I know take saw palmetto for various reasons. I don't think they know about the potential risk of the supplement. I've never heard any of them mention experiencing any side effects.

Why aren't there more studies being done on this herb? It's a very popular herb.

@literally-- I didn't experience any sexual side effects but I only used saw palmetto extract for a very short time. I did experience nausea and some allergic reactions though. This is why I quit and I'm glad I did.

My friend used saw palmetto supplements for over a year for hair loss. He developed lots of problems after that, mainly erectile dysfunction and gynecomastia. He thinks that saw palmetto is responsible for it because he hasn't taken any other supplement or medication in this time frame.

Has anyone else experienced saw palmetto side effects like impotence?
