Healing Spices by Bharat B. Aggarwal, PhD. (Sterling 2011) is a terrific 331 page book on “How to use everyday and exotic spices to boost health and beat disease”. There are four or five pages on each of 50 spices. It's great. And in the back of the book, there are twelve pages listing health conditions and the best healing spices. For Alzheimer's disease, which my mum and her two sisters had, he lists 13 healing spices: black pepper, cocoa, coconut, curry leaf, fennel seed, marjoram, oregano, pomegranate, saffron, sage, sesame seed, sun-dried tomato and tumeric.
