Liquid Storax: a resinous juice; obtained from a large tree with angular leaves like those of the maple, and a round fruit com-posed of a number of pointed seed-vessels, called by Ray styrax aceris folio, by Linnaeus Liqei-dambar styraciflua, a native of Virginia and Mexico, and lately naturalized to our own climate. The juice called liquidambar is said to exude from incisions made in the trunk of this tree, and the liquid storax to be obtained by boiling the bark or branches in water.
Two sorts of liquid storax are distinguished by authors: one, the purer part of the resinous matter that rises to the surface in boiling, sepa-rated by a (trainer, of the consistence of honey, tenacious like turpentine, of a reddish or ash brown colour, moderately transparent, of an acrid unctuous taste, and a fragrant smell, faintly resembling that of the solid storax, but somewhat disagreeable: the other, the more impure part, which remains on the drainer, untransparent, in smell and taste much weaker, and containing a considerable proportion of the substance of the bark. What is most commonly met with under this name in the shops, is of a weak smell, and a grey colour, and is supposed to be an artificial composition.
Liquid storax has been employed chiefly in external applications. Among us, it is at pre-sent almost wholly in disuse.
