Micheal Murray and Pizzorno are some of the most prolific natural medicine authors out. They are also founding fathers of the Bastyr College of Naturopathic Medicine; a very well respected institution. I am a medical student myself and found this book to be just as in depth (and much more useful) as many of my biochemistry/nutrition class notes! The authors give SPECIFIC (and refreshingly moderate) recommendations for a variety of illnesses, and back up their recomendations with very extensive references from various journals. They also describe the etiology of the illness very well, telling the reader WHY they have the problem they do...very few books for laypeople of any type do this. I cannot give this book high enough praise. It has certainly changed the way I will treat my own patients.
