Aroma therapy is an essential part of traditional Chinese Medical System, Ayurveda, Unani, Tibetan and to some extent Homeopathy, Allopathy, Naturopathy and many other traditional therapies or Alternate Systems Medicines. Aroma therapy can also relieve stress-related problems, insomnia, headaches, various skin diseases and infections. This therapy helps remove most of the digestive disorders, respiratory and asthmatic problems, nasal blockage, menstrual problems, etc. In this book I have tried to explain in reasonable and requisite details, variables uses of essential (aromatic) oils in health and disease. In addition, other uses like massage, bath, inhalation, sexual stimulation, beauty enhancement, upkeep of body in general, local applications (of course when diluted with another vehicle), scents, fragrances, hair oils, cosmetics etc.
