Mosby's Handbook of Herbs & Natural Supplements by Linda Skidmore-Roth (2001, Paperback)

I think that overall this is a good book. It does contain some medical basis as it does not recommend anything really for pregnant women or kids ect unless it has been extensively test. However, natural products are not extensively tested because the don't make anyone a lot of money. This book is useful if you want to convince you doctor to let you try something more natural for things since it does contain the latest research. Good luck on that. Sometimes you have to be your doctor and educate yourself.
