α-terpineol, terpinen-4-ol and 4-terpineol are three closely related monoterpenoids. The aroma of terpineol is compared to lilacs and blossoms. Terpineol is often found in cannabis varieties with high levels of pine, which unfortunately mask the fragrant aromas of terpineol.
Terpineol, especially α-terpineol, has calming, relaxing effects. It also exhibits antibiotic, AChe-inhibitory as well as antioxidant and antimalarial properties.
