This is the most up-to-date encyclopedia of aromatherapy available today, with over four hundred entries covering more than 200 medical conditions and 82 essential oils. It explains the properties of essential oils and the health conditions that benefit from them. There is also advice on hazardous oils. There are recipes and formulae for baths, creams and tonics. All the entries are comprehensive and fluently written, and provide an easy-to-understand introduction to a wide range of topics.Called “the aromatherapist"s Bible” by The Aromatherapy Quarterly, the A-Z has sold over 300,000 copies worldwide, which explains why it has earned and kept its place among the handful of indispensable reference books on aromatherapy.
