What is Linalool?

Linalool is a monoterpenoid and has been described as having floral and lavender undertones. Varieties high in linalool promote calming, relaxing effects. Linalool has been used for centuries as a sleep aid. Linalool lessens the anxious emotions provoked by pure THC, thus making it helpful in the treatment of both psychosis and anxiety. Studies also suggest that linalool boosts the immune system; can significantly reduce lung inflammation; and can restore cognitive and emotional function (making it useful in the treatment of Alzheimer’s disease).

CannaGlobe Key Cannabis Terpenes Linalool

The terpene linalool is made within the same shiny, resin-filled glands (trichomes) covering cannabis flowers as THC and CBD. Linalool is also found in over 200 plant species aside from cannabis. Some of the plants in which linalool is commonly found include: coriander, basil, oregano, green tea, nutmeg, sage, thyme, lemons, and mandarin oranges. However, linalool is perhaps most recognizable in lavender and is known for lavender’s pleasant, floral scent. In addition to its appealing aroma, linalool has been linked to a number of health benefits.

Anti-inflammatory and pain-reducing effects

Linalool exhibits properties associated with an anti-inflammatory agent. According to an animal study published in the Journal of Phytomedicine in 2002, linalool plays a “major” role in anti-inflammatory activity. A 2003 study found that mice given a linalool dose of 25 to 75 mg/kg displayed significant pain reduction.

Anti-anxiety effects

Researchers from Japan recently studied the effect of linalool on mice. They found that exposure to linalool vapor reduced anxiety through the sense of smell; not by absorption into the bloodstream via the lungs. Researchers also observed that linalool did not impair muscle coordination, unlike some prescription anti-anxiety drugs.

Effects on sleep

It’s no surprise that linalool is also known for promoting sleep given lavender’s reputation for its relaxation effects. Investigators in 2009 examined the sedative effects of inhaled linalool on mice. The study found one hour of inhaled linalool resulted in drowsiness. Again, linalool didn’t affect muscle coordination the way prescription drugs for sleep potentially can.

Effects on Alzheimer’s Disease

Alzheimer’s disease is known for a build up of protein plaques in the brain causing memory and communication problems. A study published in 2016 in the journal of Neuropharmacology examined the effect of linalool in a mouse model of Alzheimer’s. Researchers gave mice linalool by mouth for 3 months. The study found that linalool reversed the plaque build up in mice brains and improved memory through an anti-inflammatory effect.


Linalool, the primary terpene in lavender and one of the more common terpenes in cannabis, can be taken orally, applied topically, or inhaled. It can be used to treat inflammation and pain, anxiety, and difficulty sleeping. Animal studies also suggest linalool may one day play a role in the treatment of Alzheimer’s disease. However, as with all compounds in the cannabis plant, more research is needed. And with further research comes expectations for the discovery of therapeutic benefits currently unknown.
