Oil of turpentine; Spirits of turpentine. The trees from which the varieties of common turpentine met with in commerce are procured, are inhabitants of the forests of the colder regions of Europe and North America, and most of them are cultivated in the British isles ; they are placed in the Natural family Conifera. {Pina- cece Lindley,) and in the Linnaean class and order Monoecia Monadel- phia. Preparation.— Common Turpentine, Terebinthina vulgaris, is procured in America, by cutting off the outer bark near the root of the tree, and mak- ing an incision through the inner bark into the wood ; as the turpentine ex- udes, it flows into a hole dug in the earth, whence it is removed into casks. Volatile oil of turpentine, is an article of the Materia Medica in the Lond. and Edin. P s. being always prepared by the manufacturer on the large scale. The Dublin College gives the following formula for its'preparation. Common turpentine, by weight Ibv.; water, by measure ibiv.; distil the oil from a copper alembic; yellow resin will remain after the distillation. This oil is further directed to be purified ; Oleum Terebinthina purifica- turn, L. E.—reclificalum, D. (Oil ol turpentine, by measure Ibij. (Oj.; L. E.); water, by measure ibiv. (Oiv.; L.

Physical Properties.—Oil of turpentine is a transparent, colour- less, limpid fluid ; of a peculiar, penetrating, balsamic odour ; and a pungent, bitter, disagreeable taste. Sp. gr. '872 at 50°F. Chemical Properties.—It is composed of C20 H16. It is very soluble in ether, less so in alcohol, and very sparingly soluble in warer. Exposed to the air it gradually absorbs oxygen, thickens and becomes yellowish. It boils at 314°, and cooled down to—17° it de- posits white crystals slearoplen, which are heavier than water. Oil of turpentine is very inflammable, burning with a heavy, yellowish flame, and much smoke ; in chlorine gas it takes fire spontaneously. Therapeutical Effects.—As the most effectual remedy we pos- sess for the expulsion of tape-worm, oil of turpentine stands deserved- ly in high repute. It operates as a specific poison to the parasite, causing its immediate death, and afterwards, in consequence of its cathartic properties, expelling it from the body. It has been also used with much benefit in the form of enema for ascarides in the rec- tum. (See, Cathartics, Diuretics and Stimulants.) Dose and Mode of Administration.—As an anthelmintic; for adults, f|ss. to f§ij.; for children, f3i. to f§ss. It may be given either floating on the surface of water, or made into an emulsion with mucilage, (of which it requires equal portions,) or with yolk of egg, (one to every ounce.)—Enema Terebinthina:, D.
