Terpenes (general)


terpene profile
Written by Cara Wietstock

Alpha-Terpineol is the terpene responsible for the antifungal activity in Melaluca alternifolia, commonly called tea tree.

This week we will explore alpha-Terpineol. This aromatic molecule is reminiscent of the forest. It mixes the common aromas of pine and clove. The moniker terpineol can be found labeling any combination of four monoterpene alcohol isomers. It occurs naturally in more than 150 plants alongside cannabis. Oftentimes, terpineol occurs as α-Terpineol. It also generally shows up alongside pinene, which has a very pungent aroma. This is why it is harder to detect this terpene in cannabis using the senses alone. 

Because of its delightful scent, it is often used in the perfume and soap industries. α-Terpineol is responsible for the familiar pine aromatics in a well grown batch of Jack Herer flowers. This terpene is also found in White Widow, OG Kush, and Girl Scout Cookies.


α-Terpineol is found in:

  • Tea tree
  • Clary sage
  • Coriander
  • Lilac
  • Lime blossoms
  • Lemon
  • Star anise
  • Mandarin orange
  • Rosemary
  • Lavender
  • Juniper
  • Eucalyptus


This terpene is currently being studied as a(n):

  • Antibiotic
  • Antioxidant
  • Anti-tumor
  • Sedative
  • Anti-inflammatory
  • Antimalarial
  • Anxiolytic
