This book is brilliant!  When I was required to post in 'areas of focus', I was a bit frustrated to not find a match to choose.  'Alternative Medicine, although an aspect of this work, does not do it justice.
Mr. Buhner speaks from the plce of deep experiential knowledge in the realms of the heart as an 'organ of perception'. 
If you work in the realm of Herbal study, or have a focus of deeping our connections- to the natural world- through the heart, I highly recomend this book!
