Anise essential oil, Pimpinella anisum, possesses a fragrant aroma similar to licorice. Anise seed oil is used in massage formulations to help alleviate muscular aches and pains. Anise is also a useful expectorant. When used in soap, anise is said to mask human odors, making it a good addition to fisherman's or hunters soap.
