Oleum Cari Oil of Caraway, U.S.P. -- (Syn., Ol. Cari., Caraway Oil; Br. Oleum Carui; Fr. Essence de Carvi; Ger. Oleum Carvi, Kummelol, Carvon.) This volatile oil, obtained by steam distillation from the dried ripe fruit, should yield not less than 50 p.c. of carvone, and is a colorless, pale yellow liquid, characteristic odor and taste, soluble in 8 vols. of 80 p.c. alcohol, sp. gr. 0.905, dextrorotatory; contains a ketone -- carvone (d-carvone, carvol), CHO, at least 50 (50-65) p.c., a terpene -- carvene (d-carvene, citrene, hesperidene, d-limonene), CH, 35-50 p.c., and an alcohol, CHOH, etc. Carvone may be obtained by treating the oil with alcoholic solution of ammonium sulphide, decomposing the resulting crystals with potassium hydroxide; it is a viscid, yellowish, oily liquid, creosote odor and taste, closely related to menthol and myristicol, identical with thymol, cuminic alcohol and carvacrol, this latter being the product of distilling a mixture of caraway oil and potassium or sodium hydroxide (thus expelling carvene), decomposing residue with sulphuric acid, rectifying; useful in toothache, by inserting it into cavity. Should be kept cool, dark, in well-stoppered, amber-colored bottles. Dose, mij-5 (.13-.3 cc.).
