Geraniol

Geraniol is a monoterpenoid alcohol (C₁₀H₁₈O) that serves as the primary component of citronella oil and is a major constituent of rose and palmarosa essential oils. Its sweet, floral aroma—often described as rosy with waxy citrus undertones—makes it one of the most widely used compounds in the perfume and flavoring industries.

Beyond its aromatic appeal, geraniol plays fascinating roles in nature: honeybees produce it to mark nectar sources and hive entrances. It functions as an effective natural insect repellent, particularly against mosquitoes. In biochemistry, geraniol is a crucial precursor in the biosynthesis of other terpenes and cannabinoids. Research has explored its neuroprotective and antioxidant potential, making it of interest for neuroprotective applications.
