The most comprehensive and scientifically accurate guide on Kratom today. Unlike virtually all of the books on Kratom which aren't much more than 34-page term papers turned into "books," this is a comprehensive guide to the subject. It is carefully researched and written by an expert in human physiology, Dan Chiras, author of over three dozen books, including a college textbook, Human Biology. The coauthor, Linda Stuart-Chiras, holds a BS in biochemistry and has been a registered dietitian.. This book covers health benefits of Kratom, types of Kratom and their effects, possible side-effects, how to determine a safe dose, how to purchase from reliable companies, growing Kratom in your home, how to use it safely, avoiding dependence and addiction, and where it is legal and where it is not. It's easy to read, full of great information for Kratom beginners and individuals already familiar with this medicinal herb.
