Camphor brings a fresh, terpenic aroma to various fragrance compositions. It occurs naturally in several plants, including basil (camphor chemotype), camphor sage, and cardamom essential oil. Its primary natural source remains the camphor tree, which belongs to the same species as Ho Wood essential oil.
Camphor is a trigeminal ingredient, meaning it activates the trigeminal nerve, which handles motor and sensory functions in humans. This property gives camphor its characteristic cooling sensation in the nose when inhaled. It is widely used in perfumery to add freshness and clarity to compositions.
