Aromatherapy 101 is the starting point. In Aromatherapy 101 we start at the beginning and systematically go through everything you need to know to safely and effectively use essential oils every day. You learn how essential oils can be used to enhance the health and happiness of yourself, your family and friends. If you only intend to use essential oils privately this may be the only course you ever need to take. On the other hand, if you are intending to incorporate them into a business venture, continuing on with the Aromatherapy 201 course may be appropriate.
