The oil is a pale olive or pale yellow, mobile liquid.
The flavor of this oil is surprisingly weak, a fact which is due to the water-solubility of carvone.
The oil has a very warm, slightly green-herbaceous odor, penetrating and powerful, truly reminiscent of the odor of the crushed herb.
The flavor is equally warm, almost biting, spicy-herbaceous, somewhat bitter.
In perfumery, the oil finds some use for its peculiar herbaceous-green effect in lavender-fougére or even in jasmin compositions.
Spearmint Oil is used primarily in flavors for toothpaste, chewing gum, candy, mouthwashes, etc. where it has attained great popularity as a modifier for peppermint.
Spearmint Oil is produced by steam distillation of the flowering tops of the plants, which are partially dried prior to distillation.
