Benzoin is made from the resin of a small tree growing in tropical Asia. It has a delicate, balsamic odor and is used in skin care products to heal dry, chapped skin and wounds. When combined with other respiratory oils, it helps with coughs, colds, asthma and bronchitis. Benzoin is warming to painful joints and helps with rheumatism and gout. It is anti-inflammatory and antiseptic.
