This book is unfortunately incomplete, although its intentions are good. Most people are combination types--kapha-pitta, vata-pitta, etc. but the book ignores this necessary fact in its presentation, and acts as though every person is a pure type. After a long, difficult search, I found this subject addressed AFTER the main body of the material--and not in any convenient or helpful manner. Both authors totally ignored my phone calls and emails asking for help on this issue, which doesn't do anything to inspire confidence or a positive attitude toward the book. Frawley is a prolific author and should do more than just present an overview, which would require a live teacher to make sense of the material.
