Lavender essential oil has been known for its antiseptic, anti-microbial and analgesic properties. When inhaled through vaporised air lavender also acts as a sedative and relaxant, helping to reduce feelings of stress. Lavender has also been noted for its ability to accelerate wound healing although scientific evidence to back this up is patchy. Lavender has also been promoted as a topical agent for the relief of itchy skin after research found the oil may inhibit parts of the allergic pathway.
