What Is Linalool Terpene? Aroma, Uses and Research

Linalool is a floral-smelling terpene found in lavender, mint, coriander and some cannabis. Most research on its effects is in animals: in a 2018 mouse study, the smell of linalool reduced anxiety-like behavior, and the effect did not occur in mice that could not smell. Research in people is limited.

It is also found in essential oils, aromatherapy products and some cannabis products, and NIH says studies have suggested that a lavender oil product, taken by mouth, might be beneficial for anxiety, though that research has several limitations.

What Is Linalool Terpene?

Linalool is a naturally occurring compound found in many plants, where it mainly adds aroma. It is added to cosmetics, essential oils and cleaning agents, mainly for scent. Most of what is known about its effects in the body comes from animal studies.

What Does Linalool Smell Like?

Linalool’s most recognizable feature is its floral aroma, often compared to the scent of lavender. Lavender oil is popular in aromatherapy, though NIH says it is unclear whether lavender aromatherapy helps anxiety, stress or sleep.

Its pleasant scent is the main reason it is used in products marketed for relaxation.

Where Can Linalool Be Found?

Linalool occurs in many plants and in some foods. The best-known source is lavender, whose essential oil carries the familiar scent. Besides lavender, linalool is present in coriander, basil, thyme, and mint. In these plants, linalool is one of several compounds behind the scent. Additionally, trace amounts of linalool are found in apples, grapes, tea leaves, and certain citrus fruits.

In cannabis, it gives some strains a floral, slightly spicy smell.

Which Cannabis Strains Contain Linalool?

Several cannabis strains are reported to be rich in linalool, which shapes their aroma. Strains such as Amnesia Haze, Lavender and LA Confidential are often listed as high in linalool, though lab results vary by batch and calming effects from these strains have not been tested.

Linalool-rich strains are also marketed for stress and pain, and those uses are untested too. The idea that linalool works better with other terpenes, the entourage effect, is still a hypothesis.

Identifying cannabis strains with high linalool content can be as simple as checking the product’s terpene profile. Many dispensaries provide this information, making it easier for consumers to choose strains that suit their needs. A terpene profile tells you about aroma, not about which product will help a health problem.

What Is Linalool Used For?

Linalool turns up in a wide range of products:

Aromatherapy: Lavender oil, which contains linalool, is sold for aromatherapy; NIH’s caution on that use is noted above.

Topical Applications: Linalool is common in skincare products and essential oils for its scent, and it has not been shown to relieve skin irritation.

Cleaning Products: Linalool’s pleasant aroma makes it a common ingredient in cleaning agents, where its job is scent, not disinfecting.

Cosmetics: Linalool is frequently found in perfumes, lotions, and other personal care items, adding fragrance.

Dietary Supplements: Lavender oil supplements contain linalool; check with a pharmacist about your other medicines before taking one.

What Does Research Show About Linalool?

Antimicrobial Claims

Linalool is sometimes promoted as antimicrobial, but no study cited here tests that in people, and it is not a treatment for infections.

Anxiety-Like Behavior in Mouse Studies

In a 2018 mouse study, smelling linalool reduced anxiety-like behavior through GABA receptors, the system some anxiety and sleep drugs act on; effects on sleep in people are unproven.

Anxiety and Depression: What Studies Show

NIH says studies suggest a lavender oil product taken by mouth might help anxiety, including anxiety with symptoms of depression; linalool on its own has not been tested this way.

Stress and Immunity Claims

Claims that linalool boosts immunity by reducing stress have not been tested.

Chronic Pain

Linalool is sometimes promoted for pain, but no study cited here tests it for chronic pain in people.

Should You Try Cannabis with Linalool?

Two questions come first: why you want to try a linalool-rich strain, and who should help you decide.

On the first question, no linalool-rich strain has been tested for stress, anxiety or chronic pain, and THC itself can cause anxiety in some people.

That is why the decision belongs with a medical marijuana doctor, who can weigh your medical history and your other medicines.

Linalool Effects: How Does Linalool Affect the Brain?

Researchers have studied how linalool acts on the brain, mostly in mice. In those mouse studies, one effect seen is less anxiety-like behavior. As the 2018 mouse study at the top of this post found, that effect depended on smell.

Whether linalool acts on the endocannabinoid system in people is not established, and its role in the entourage effect is unproven. Nerve-protecting effects in mice have also made linalool a subject of research on conditions like Alzheimer’s disease, covered in the next section.

What Has Alzheimer’s Research in Mice Found About Linalool?

In a 2016 study in old mice bred to develop Alzheimer’s-like disease, linalool reduced amyloid plaques and brain inflammation and improved learning. The authors called it a candidate for further preclinical study; it has not been tested in people with Alzheimer’s disease or shown to lower the risk of cognitive decline.

More research is needed before anyone can say whether linalool protects the brain in people.

Conclusion

Linalool is known for its soothing aroma. A lavender oil product might help anxiety, NIH says, while the anti-anxiety and Alzheimer’s findings on linalool itself come from mouse studies. In cannabis it shapes aroma, and its therapeutic role there is unproven.
