Thomas Cowan, M.D., has studied and written about many subjects in medicine including the heart, autoimmune disease, nutrition, anthroposophical medicine and herbal medicine. He is the author of Human Heart, Cosmic Heart and Vaccines, Autoimmunity and the Changing Nature of Childhood Illness, and Cancer and the New Biology of Water all published by Chelsea Green; as well as the principal author of The Fourfold Path to Healing; and co-author (with Sally Fallon) of The Nourishing Traditions Book of Baby and Child Care.

Dr. Cowan has served as vice president of the Physicians Association for Anthroposophic Medicine and is a founding board member of the Weston A. Price Foundation®. He also writes the “Ask the Doctor” column in Wise Traditions in Food, Farming, and the Healing Arts (the Weston A. Price Foundation’s quarterly magazine) and has lectured throughout the United States and Canada.

In 2016, he and his family launched Dr. Cowan's Garden, a company that makes and sells organic vegetable powders to help people diversify their vegetable consumption. He has three grown children and lives and practices medicine in San Francisco.

Let me first say that I love the new book, your most recent interview on Dr. Mercola’s site, and have been using Dr. Cowan’s Garden products for almost 2 years.   I am also a huge fan of Dr. Zach Bush who we have interviewed who did the intro to your book.  Shameless plug for his product Restore which I credit as the key to eliminating my seasonal allergies.
