If you or a friend or a family member take ginkgo biloba, St. John’s wort, garlic, saw palmetto, milk thistle, chondroitin sulfate and glucosamine or echinacea, you need to read this article.
There is a great quote at the end of the article; “There is a name for alternative medicines that work… It’s called medicine!”
