Humulene is one of the main terpenes in hops, from which it gets its name. Humulene is also called alpha-caryophyllene. Like beta-caryophyllene, humulene is a cannabinoid and sesquiterpene, although it does not contain a cyclobutane ring. Humulene is a powerful anti-inflammatory and an anti-pain compound. It also has anti-cancer properties. Humulene is unique because, like THCv, it acts as an appetite suppressant, showing promise for weight loss treatments.

The antibacterial activity of basal fir oil (Abies balsamea) seen to be effective with Staphylococcus aureus. At 2.6 microg/mL, humulene was shown to have a minimum inhibitory concentration, the most potent of all the terpenes evaluated in the study.

Humulene was shown to be a good anti-inflammatory across a wide range of inflammatory markers. Its effects were comparable to dexamethasone in rat and mouse models. Humulene has been shown to have rapid onset and relatively good absorption with both oral and topical administration routes. In airway allergic inflammatory routes, humulene was shown to be effective orally or through aerosol.

Humulene was elucidated to be potent against several solid tumor cell lines. The molecular mechanism involves producing reactive oxygen species, or free radicals, and depleting natural antioxidants in the cells. Humulene was also shown to work synergistically with beta-caryophyllene in delivering the molecule to cancer cells, thus increasing the cytotoxicity of humulene on several cancer cell lines.

Humulene was shown to be toxic against early third-stage larvae of the malaria, dengue, and filariasis mosquito vectors, An. stephensi, Ae. aegypti, and Cx. Quinquefasciatus. Also humulene was proven to be a repellant to the adult mosquitos as well. In addition humulene was only toxic to non-pathogenic aquatic organisms, Diplonychus indicus and Gambusia affinis at much higher levels than those used against the mosquitos.
