This has been my herbal bible since 1999. I am so grateful I purchased this book and learned how to use it. I refer to it for just about everything now. As an herbal educator, this book has given me all the information I needed to develop my skills, learn the language of plants, and translate that into actionable practices to help myself, my family, and others reach our optimum health. I highly recommend it to anyone, at any level who wants to learn how to use plants in synergistic combinations for alternative healing practices.
