Liquidambar orientalis, commonly known as oriental sweetgum or Turkish sweetgum, is a deciduous tree in the genus Liquidambar, native to the eastern Mediterranean region, that occurs as pure stands mainly in the flood plains of southwestern Turkey and on the Greek island of Rhodes.
The hydrocarbon styrene is named for Levant styrax from this species (Liquidambar orientalis), from which it was first isolated, and not for the genus Styrax itself; industrially produced styrene is now used to produce polystyrene plastics, including Styrofoam.
Diluted with a suitable carrier oil, it is used externally in traditional medicine for abrasions, anxiety, bronchitis, catarrh, coughs, cuts, ringworm, scabies, stress-related conditions and wounds. It is a different product than the benzoin resin produced from tropical trees in the genus Styrax.
