This book is an excellent introduction to alternative medicine. While I would not agree with everything contained in the book, I think this book has information which will be helpful to most. You can combine many alternative therapies with conventional medicine to aid healing. The majority of the book covers alternative medicine approach for the most common ailments. I found the chapter on weight loss helpful.

I suggest you read Tom Cowan‘s website to see if this is what you are looking for. Start with Nourishing Traditions first.
