Source, History, and Preparation.a Thymol was discovered by Caspar Neumann in 1719. It was purified, in 1853, by M. Lallemand, who gave it the name "thymol," and ascribed the formula (old notation) C20H14O2, the same being accepted at the present day as correct, corresponding to C10H14O of the new notation. Thymol is a phenol (iso-propyl-meta-cresol), and is isomeric with carvacrol (iso-propyl-ortho-cresol). It is found in oil of thyme, oil of horsemint, and oil of Carum Ajowan, De Candolle (Ptychotis Ajowan), a plant from the East Indies; the thymol of commerce being derived from thyme oil. The yield of thymol from this source, however, is comparatively small and quite variable (from less than 1 to 38 per cent; see Amer. Jour. Pharm., 1882, p. 521). Larger quantities of thymol occur in the oil of horsemint (see Monarda). Thymol exists in oil of thyme, associated with two hydrocarbons of greater volatility, cymol (C10H14), and thymene (C10C16)
