Aromatherapy uses essential oils. These have plant-derived fragrances. Almost all aromatic plants contain essential oils. The alleviating effects of fragrances have been known for decades. In 1928 the French chemist Rene Gattefosse developed a healing method on the basis of natural plant scents. Since then, more and more discoveries have been made in the field of aromatherapy. The skilled application of the oils activates the healing power of the body and increases your feeling of well-being. The essential oils can function in two ways, depending on the way in which they are used: affecting the brain directly by binding to nerve endings in the nose; and acting locally when applied to skin.
