Terpineol (α-terpineol, β-terpineol, γ-terpineol and Terpinen-4-ol) is a very common terpene found in numerous plants around nature, with its pleasant smell being used in many soaps, lotions and perfumes. It carries a distinct pine, smoke-based aroma that some compare to lapsang souchong tea. It occurs naturally in lilacs, pine trees, lime blossoms, eucalyptus sap, cajuput oil and petitgrain oil.
Terpineol in particular has been shown to assist with cancer, as well as having antibiotic, antioxidant, antimalarial and sedative effects. Strains containing high terpineol include Jack Herer, White Widow, GSC and OG Kush.
