Some of the most important pioneers of aromatherapy are René-Maurice Gattefossé, Jean Valnet, Marguerite Maury, Micheline Arcier, Robert T. Tisserand, Dr. Lawless and Shirley Price. Over the years, they and many others have continued to discover new areas in which herbal essences can contribute to fighting disease, so that aromatherapy has countless indications now. A short list of the first-discovered applications of essential oils can serve as an example: heal wounds, regulate blood pressure, strengthen the immune system and alleviate depression. Moreover, the research conducted by Professor Rovesti (University of Milan), Dr. Gatti and Dr. Cayola proved the holistic effects of essential oils as early as the 1920s. As the aromatherapy specialist Bernd Griasch explains, “Essential oils affect the body’s functions as well as the mind and the soul. Therefore aromatherapy is the perfect solution to the quest for a holistic therapy”.
