Dr. Bowling's book is a fist-rate description of the terrain of alternative medicine. Unlike other MS-specific books about alternative medicine, his is based on a review of published literature rather than on personal experience, anecdote and fancy.
Part of Dr. Bowling's accomplishment is that he has managed to catalogue a diverse and hard-to-define area. More imortantly, it describes, in succint and easy-to-understand and language, the published research that is available on about 40 different areas of alternative medicine.
Don't buy the book thinking there is a cure for MS to be found in its pages. On the other hand, if you are looking for a starting point for understanding alternative medicine, then this book is a useful resource.
