Guaiol is a naturally occurring sesquiterpene alcohol found in several plant species, including cypress, pine, and guaiacum. It possesses a distinct woody and pine-like aroma. Guaiol is classified as a terpene and has been used in traditional medicine for its potential therapeutic properties.

.Guaiol has demonstrated various potential health benefits. It has been investigated for its antimicrobial, anti-inflammatory, and antioxidant effects. Guaiol has also shown potential as an analgesic and anxiolytic agent.It shares a common biosynthetic pathway with cannabinoids in cannabis plants. It is derived from the same precursor, geranyl pyrophosphate (GPP), that is also involved in the production of cannabinoids. This shared biosynthetic pathway suggests a potential relationship between guaiol and cannabinoids. Furthermore, guaiol is one of the many terpenes found in cannabis and contributes to the aromatic profile and potential therapeutic effects associated with different cannabis strains. It is believed that the presence of guaiol, along with other terpenes, may contribute to the entourage effect, where the combined action of multiple compounds in cannabis, including cannabinoids and terpenes, leads to enhanced therapeutic effects.
