Also known as alpha-terpinolene, this terpene possesses potential mildly to moderately sedative effects. It naturally occurs in rosemary, sage, lilac, conifer trees, apple trees, and tea trees. It’s also a natural constituent of many essential oils. This terpene possesses potential antifungal and antibacterial properties and may be useful in calming the central nervous system.

It displays potential sedative properties, so it may be used in aromatherapy through essential oils like tea tree oil. Unlike terpenes like phellandrene, which have an energizing effect, this terpene may reduce anxiety and calm the mind. It’s also often found in lilac-scented body lotions and oils.

What are the effects of terpinolene? 

What is terpinolene good for? Researchers have investigated the potential antifungal, antibacterial, and sedative effects of this terpene. 

Antifungal properties

Terpinolene-rich tea tree oil is one of the most studied essential oils for its potential antifungal properties that extend from ringworm to toenail fungus. A 2015 study published in the Journal of Applied Microbiology found a link between tea tree oil and antifungal activity in the fungus that attacks wine grapes known as Botrytis cinerea. 

Another study conducted in 1996 by the Skin Pharmacology Society found that tea tree oil may effectively combat certain yeast fungi and conditions like dandruff and fungal infections of the skin.  

Antibacterial effects

One 2010 study published in Natural Product Research looked at the antibacterial and antimicrobial properties of an essential oil containing terpinolene. The researchers revealed that the oil containing this terpene at six percent (6%) inhibited the growth of Bacillus subtilis. This bacterium is found in soil and the gastrointestinal tract of humans.   

Sedative effects

One 2013 animal study featured in the Journal of Natural Medicines revealed that the essential oil that contained terpinolene acted as a sedative after being inhaled by the subjects.

Characterized by a piney but not overpowering scent that bears a hint of sweet fruity fragrance, these strains are known for their relaxing, anti-anxiety, and pain-relieving effects. Despite being present in small quantities in several hemp strains, this terpene contributes to the overall qualities of each strain by working in synergy with cannabinoids. The theory that suggests that hemp’s compounds work synergistically to maximize its healing benefits is known as the entourage effect.
