Pepper Oil Black (aromatherapy)

Oil of Black Pepper is an almost water-white or pale greenish-gray, mobile liquid which becomes more viscous on ageing. Its odor is fresh, dry- woody, warm-spicy, reminiscent not only of the odor of dried black pepper, but also of elemi, cubeb and other essential oils of high terpenesesquiterpene content. The flavor of the oil is surprisingly flat, somewhat dry-woody. At high concentration, the taste is slightly bitter. When more dilute, it presents only a mild spiciness. The essential oil has no pungency at all since the pungent principles of black pepper are not distillable with steam.
