A floral, rose-like terpene found in cannabis and geraniums, studied for potential neuroprotective and antioxidant effects.
Geraniol is a floral terpene with a sweet, rose-like aroma that also carries notes of citrus and stone fruit. It is one of the primary aromatic compounds in rose oil, geraniums, and lemongrass. In cannabis, geraniol appears as a minor terpene that adds floral complexity to certain strain profiles.
Geraniol has attracted scientific interest for its potential neuroprotective, antioxidant, and anti-inflammatory properties. A study in Naunyn-Schmiedeberg's Archives of Pharmacology found geraniol demonstrated neuroprotective effects in a mouse model of neuropathic pain. Additional research has explored anticancer properties, with geraniol showing the ability to inhibit tumor growth in several in vitro studies. The terpene is also a natural insect repellent, used commercially in citronella products.
Cannabis strains with higher geraniol levels include Amnesia Haze, Great White Shark, Afghani, Lemon G, and Harlequin. Geraniol-rich cannabis tends to have a distinctly floral, sweet aroma that stands out from the more common earthy or citrus profiles. This terpene is particularly prized in craft cannabis and small-batch artisanal products where aromatic complexity is valued.
