Geraniol is an acyclic monoterpene alcohol with a sweet, rose-like aroma that makes it one of the most widely used terpenes in the fragrance and flavoring industries. It is the primary component of rose oil, citronella oil, and palmarosa oil, and is found naturally in geraniums, roses, and lemon. Geraniol has been used in perfumery for centuries and holds GRAS status from the FDA.

Recent research has revealed geraniol's remarkable neuroprotective potential. Studies published in Neurotoxicology demonstrated that geraniol protected dopaminergic neurons in models of Parkinson's disease, reducing oxidative stress and inflammation in brain tissue. Additional research has shown broad-spectrum antimicrobial activity against various bacteria and fungi, as well as significant antioxidant properties that may help combat cellular aging.

In terpene blending, geraniol provides an elegant, sophisticated floral character that elevates blend quality. Its high boiling point means it persists longer than many other terpenes, providing lasting aroma. Geraniol pairs beautifully with linalool for complex floral profiles and is commonly found in strains like Harlequin, Afghan, and Amnesia Haze.
