A piney, woody alcohol-based terpene found in cannabis and cypress pine, studied for potential anti-inflammatory properties.
Guaiol is a sesquiterpenoid alcohol found in cannabis, guaiacum (lignum vitae wood), and cypress pine. Unlike most terpenes, which are oils, guaiol is a terpene alcohol with a liquid consistency. It produces a piney, woody, rose-like aroma and has been used in traditional medicine for centuries.
Guaiol has been studied for anti-inflammatory, antimicrobial, and insect-repellent properties. The guaiacum wood from which guaiol takes its name has been used in traditional Caribbean and South American medicine for treating arthritis and other inflammatory conditions. Modern research has explored guaiol's potential as an anti-cancer agent, with studies showing it may inhibit cell growth in certain tumor lines. A study in Oncotarget found guaiol enhanced the anti-tumor effects of conventional chemotherapy drugs in non-small cell lung cancer models.
Guaiol appears in strains like Blue Kush, Liberty Haze, Pennywise, and Jean Guy. It typically appears as a minor terpene but contributes to the complex woody-floral notes found in many popular strains. As cannabis terpene research expands beyond the most abundant compounds, guaiol is receiving more attention for its potential contribution to the therapeutic properties of whole-plant cannabis preparations.
