The most common of these is liquid storax, a brown or gray semifluid substance of an agreeable aromatic odour and balsamic taste, sometimes used in perfumery, and in medicine as an expectorant.
A yellow aromatic honeylike substance, resembling, and often confounded with, storax, is obtained from the American sweet gum tree (liquidambar styraciflua), and is much used as a chewing gum, called sweet gum, and liquid storax. Cf. Liquidambar.
