I enjoyed the author's description of basic Ayurvedic Medicine (TAM) principles and philosophy; as for the monographs of herbs and their actions not so much. I own the 2nd ed. and found many problems with the Materia Medica of the book. When the authors describe Basil (Ocinum spp.)they misrepresent the plant as Tulsi which is actually Holy Basil (Ocinum Sanctum)- one of the most used plants in TAM; the adaptogenic qualities of Tulsi are not present in other types of Basil. Another misrepresentation is Hibiscus (Hibiscus Rosa-Sinesis) for which they use the wrong species of plant (actually Hibiscus sabdariffa) and the wrong part of the plant used (the flower is not used as the book says but the calyx); Wikipedia also states the Hibiscus Rosa-Sinesis flower is used to shine shoes and in devotions to the god Devi, not specifically for beverages as the Hibiscus sabdariffa. Yes I did like the descriptions of TAM doshas and philosophy but if you wish to try the herbs mentioned in the book I recommend finding another book like those by Tillotson, Murray, Pizzarno, Gladstar, Hoffman or even Penny C. Royal for more dependable herbal monographs.
