A thick oily liquid, C10H13.OH, of a strong taste and disagreeable odor, obtained from oil of caraway (Carum carui).

Carvacrol, or cymophenol, C6H3CH3(OH)(C3H7), is a constituent of the ethereal oil of Origanum hirtum, oil of thyme, oil obtained from pepperwort, and wild bergamot. It may be synthetically prepared by the fusion of cymol sulfonic acid with caustic potash; by the action of nitrous acid on 1-methyl-2-amino-4-propyl benzene; by prolonged heating of five parts of camphor with one part of iodine; or by heating carvol with glacial phosphoric acid or by preforming a dehydrogenation of carvone with a Pd/C catalyst. It is extracted from Origanum oil by means of a 50% potash solution.
