Lavender is a set of flowering plants, including the species Lavandula angustifolia, that is grown in many parts of the world. Lavender essential oil is widely used in aromatherapy and aromatherapy massage in attempts to relieve conditions such as anxiety, disturbed sleep and pain. Capsules containing preparations of the oil or powder from dried lavender are also used by many for oral consumption. A number of clinical trials have been conducted to assess the effectiveness of lavender for these and other conditions.
