Welcome to Blue Moon Herbs! This website is designed to provide information about Essiac and Rene Caisse, the Canadian nurse who developed this indigenous herbal remedy from the Native Americans that shared it with her. We have recreated the original Essiac formulae with the emphasis on replicating what Rene Caisse was doing, rather than trying to change it. We have everything from the dried herbs to books by Sheila Snow and Mali Klein, the world's authorities on Essiac. We also have books, seeds, tea-making supplies, and everything Essiac! Below are some of our featured products.
