Is saw palmetto or ginkgo good to take to help lower high blood pressure?

Q: Does Saw Palmetto or Ginkgo impact BP or heart beat frequency?

A: Commonly reported side effects of both Ginkgo and Saw Palmetto involve the gastrointestinal system such as nausea, vomiting and diarrhea. High blood pressure and heart arrhythmias have been reported with Saw Palmetto use but it is not clear if the cause was the Saw Palmetto or other factors. The FDA does not strictly regulate herbal products so different brands vary widely in purity and strength. Be sure to discuss with your doctor any herbs or supplements that you plan on taking.
