Rosemary oil

Description

An evergreen shrub, Rosemarinus officinalis, with a minty aromatic smell that is native to the Mediterranean region. Rosemary leaves have been crushed, then distilled to form oil, since ancient times. The leaves contain camphor and oxygenated monoterpenoids. Rosemary oil is slightly greenish, evaporates slowly and is a strong solvent. It has been used as a retardant in oil painting but excess amounts can make the colors sticky and cause darkening. Rosemary oil was also used in perfumes, soaps, medicine and in tanning leather.
