Terpinol is obtained by boiling terpin hydrate with dilute mineral acids. It occurs as an oily body with a hyacinthine odor. Insoluble in water, but readily soluble in alcohol and in ether.

Terpinol is a valuable bronchial stimulant, and may be used for the same diseases of the respiratory passages for which terpin hydrate is recommended.

It is best given in capsules, in doses of about 2 grains (0. 12 Gm.) each, repeated from four to six times a day.
