Used in perfumery for its fresh, green, slightly citrusy aroma, perillene enhances fragrances in soaps, detergents, and cosmetics. It serves as a flavoring agent in food products due to its subtle minty and herbaceous notes. In aromatherapy, it is valued for its potential calming effects. Perillene also shows promise in research for its antioxidant and anti-inflammatory properties, making it of interest in natural product development and functional ingredients.
