Warm, nutty Salvia sclarea, one of the most commonly used essential oils, is distilled from the flowers and leaves of plants grown in the Mediterranean area. The herb was regarded as a cure-all in Roman times and has a long history of use both as a food and a medicine. When evaporated into the air or used in a bath or massage, Clary Sage has a strong, euphoric, relaxing effect. Aromatherapists employ clary sage to promote a calm sense of well-being in cases of mild depression, nervous fatigue, insomnia and convalescence from illness. It makes a soothing addition to body care products and is considered a valuable PMS aid. Avoid use with alcohol, pregnancy and driving.
