Elemi resin is a pale yellow substance, of honey-like consistency. Aromatic elemi oil is steam distilled from the resin. It is a fragrant resin with a sharp pine and lemon-like scent. One of the resin components is called amyrin.[2]
Elemi resin is chiefly used commercially in varnishes and lacquers, and certain printing inks. It is used as a herbal medicine to treat bronchitis, catarrh, extreme coughing, mature skin, scars, stress, and wounds.[2] The constituents include phellandrene, limonene, elemol, elemicin, terpineol, carvone, and terpinolene. In high doses, elemicin can cause irritation, so its concentration in cosmetics does not exceed 1%.[4]
The seed kernels are used for food, both raw and cooked. An edible oil can be extracted from the seeds, and the pulp can be stewed but is somewhat insipid. The young shoots can be boiled and eaten as a vegetable.[2]
History of the name
The word elemi has been used at various times to denote different resins. In the 17th and 18th centuries, the term usually denoted a resin from trees of the genus Icica in Brazil, and before that it meant the resin derived from Boswellia frereana. The word, like the older term animi, appears to have been derived from enhaemon (ἔναιμον): the name of a styptic medicine said by Pliny to contain tears exuded by the olive tree of Arabia.[5]
