Citronellol, or dihydrogeraniol, is a natural acyclic monoterpenoid. Citronellol is closely related to geraniol and has a floral, citrusy odor. There are two main types of citronella that contain citronellol as an active constituent: Ceylon and Java, named because of citronellol’s probable origin in Sri Lanka.

Citronellol is found in the stems and leaves of lemongrass in the form of citronella oil. It is also found in the oils of rose, geranium, chamomile, sandalwood, and catnip. 

Citronellol is commonly used in insect repellent products and is classified by the EPA as a minimum risk pesticide.¹ Citronellol’s balanced aroma also makes it a popular addition to many household and skin care products, including candles, perfumes, deodorants, and soaps. 

Citronellol has been researched for its potential use as an anti-tumor, anti-inflammatory,² and blood pressure regulating agent.³ The proven anti-inflammatory properties of citronellol could help reduce the formation of cancer cells, specifically lung cancer.⁴ 

Citronellol is likely found in cannabis strains including Amnesia Haze, Great White Shark, and Island Sweet Skunk.
