This book was a refreshing read on the many alternative medicine techniques that Dr. Weil has researched and practiced. Some of the items he discusses include how ‘traditional medical doctors’ can be pessimistic - creating bad vibes in their patients - rather than trying to explore more optimistic (ie. alternative and/or natural) treatment options. He also discusses more ‘natural ways of improving our health,’ including altering diet and natural cleansing techniques (ie. avoiding toxins and using tonics). He also has inserted many inspiring personal accounts he has collected from his patients throughout the book.
