Rosemary Gladstar books, any any of them are a bookshelf necessity
Book of Massage or any other book on Massage and Reflexology
Sweet and Natural: Desserts Without Sugar, Honey, Molasses, or Artificial Sweetener by Janet Warrington, this is a super one, but there are other wonderful cookbooks on this subject I plan on getting for myself.
Herbal Antibiotics, natural remedies for Treating Drug-resistant bacteria - by Stephan Harrod Bhuner (A Story Medicinal Herb Guide)  A very good book to explain why antibiotics are not working like they used to…composition of plants vs single cell antibiotics…..and what to use to combat what the modern antibiotics and treatments cannot.
