Germacrone is a sesquiterpene and key bioactive constituent of many essential oils. [1] It was first detected in essential oil of Geranium macrorrhizum (bigroot geranium) in 1927. [1] More recently and famously, it has played a major role in essential oils extracted from Curcuma L., which is a genus in the ginger (Zingiberaceae) family spanning over 100 species including turmeric (C.longa) and other rhizomatous herbs. [2] Plants with essential oils high in germacrone are found in many countries around the world. [1]

Germacrone is associated with a wide range of potential beneficial properties, including anti-inflammatory, antitumor, antibacterial, cough-suppressant, vasodilator, and hepatoprotective activities, among others. [1] For instance, germacrone is largely credited for the anti-inflammatory properties of C. xanthorrhiza, or Java gingera popular Indonesian medicine. The same goes for the antifungal effects of Myrica gale (sweetgale) essential oil and the broad-spectrum antibacterial activity of Asarum caulescene (wild ginger) essential oilAn extracted oil from fruits of Eugenia uniflora (Surinam cherry) exhibited 27.5% content of germacrone that is believed to largely fuel cytotoxic effects against human prostate, liver, and breast tumor cells. [1]

In mice, germacrone has been shown to prolong or provoke sleep alongside hexobarbital, possibly due to depressant effects on the central nervous system. [1]

Germacrone was found to protect mice against lethal infection from influenza A (H1N1 and H3N2) and B by inhibiting the “attachment/entry step and the early stages of the viral replication cycle” in a dose-dependent fashion. [3] In addition, when working in combination with oseltamivir, it “exhibited an additive effect on the inhibition of influenza virus infection, both in vitro and in vivo.” [3]

On a somewhat different note, germacrone has also displayed the ability to improve the skin penetration of minoxidil, a hair growth promoter, and also acted as an “anti-androgen, thereby introducing a more effective topical treatment strategy for androgenic alopecia.” [4] Androgenic alopecia is another way of saying male or female pattern baldness. Co-application was more effective than either treatment alone due to the ability of germacrone to enhance the absorption of minoxidil. [4]

The efficacy of germacrone’s abilities are exceeded only by their diversity, and we’re curious to see future studies that explore potential synergistic interactions with cannabinoids.
