What is linalool?

Linalool is a terpene compound found in more than 200 plant species. It gives certain plants a floral aroma along with a scent of spice.

It’s different than synthetic scents because it’s naturally found in flowers, spices and even cannabis. However, it can now be created in a laboratory, too. (More on avoiding synthetic scents, which can be irritating, can be found below.)

Most often it’s isolated from plants and added to creams, candles and other beauty products. Plus, it’s present in some essential oils.

Additionally, it’s a common flavoring agent in beverages and foods and has widespread use in cosmetics.

It is also known as:

• beta-linalool
• linalyl alcohol
• linaloyl oxide
• P-linalool
• allo-ocimenol
• 3,7-dimethyl-1,6-octadien-3-ol
• linolool
• linanool
• L-linalool

Mechanism of action

Linalool exerts its effects primarily through interaction with the central nervous system. Studies have suggested that it modulates the activity of gamma-aminobutyric acid (GABA) receptors, which are responsible for inhibiting neural activity, leading to sedative and anxiolytic effects.

Additionally, it has been shown to influence neurotransmitter release, contributing to its muscle relaxant properties.

Is lavender a type of linalool?

Linalyl alcohol terpene is found in plants including:

• lavender
• birch bark
• cinnamon
• mint
• rosewood
• coriander
• cilantro
• basil
• peanuts
• neroli
• cannabis (although it doesn’t have psychoactive effects like other compounds found in cannabis do)

Lavender is one of the best and most popular plant sources of linalool, as are rosewood and neroli oil. In fact, linalyl alcohol is responsible for much of lavender’s signature scent and soothing effects.

Here’s more on some of the plants with higher levels of this terpene:

• Lavender (Lavandula angustifolia): High linalool content, contributing to its calming aroma.
• Coriander (Coriandrum sativum): Contains significant amounts of linalyl alcohol, imparting a spicy scent.
• Sweet basil (Ocimum basilicum): Rich in linalyl alcohol, especially the linalool chemotype.
• Rosewood (Aniba rosaeodora): Notable for its high linalool concentration.​

The concentration of linalool in these plants can vary based on factors, such as plant part, harvest time and environmental conditions.

Benefits

Research has suggested that linalool has many health benefits and uses due to the way that terpenes modulate how certain parts of the brain work. It’s been shown that linalyl alcohol can impact one’s mood, sleep, sensation of pain, cardiac rhythms, muscles and more.

Here’s more about what we know about linalool benefits:

1. Calming and stress-reducing

Animal and human studies have demonstrated that linalool has sedative effects and can help calm an overactive nervous system.

The scent of linalool has been shown to act as a natural anxiolytic, meaning it decreases anxiety symptoms and perceptions of stress. It does this by activating the parasympathetic nervous system, which helps us “rest and digest.”

How can smelling something change how you feel so powerfully? Your sense of smell is directly linked to parts of your brain that control emotions and memory.

Olfactory (smell) receptors signal to the limbic and hypothalamic areas of the brain to release neurotransmitters, such as serotonin and endorphins, that link the nervous system to other body systems.

Certain aromas can modulate levels of neurotransmitters, making us feel calmer, energized, even euphoric. More recently, terpenes have been found to directly affect brain processing by modulating behavior of certain brain cells.

Because linalyl alcohol is capable of reducing stress, it can lead to many health improvements, including:

• better sleep
• normalized blood pressure
• less muscle tension
• fewer headaches
• improved digestion
• enhanced immunity
• more energy

2. Has anti-inflammatory and pain-dulling effects

This terpene has been shown to modulate how the brain perceives pain, giving it the ability to decrease overactive responses to injuries or illnesses. It can help with inflammation, swelling (edema), redness, irritation and other contributors to pain.

One study even found that lavender aromatherapy can be used to reduce the demand for opioids during postoperative periods following surgery.

3. Can help boost your immune system

Plants containing linalool, including lavender, are known to help fight negative effects of stress and improve sleep quality, which are both important factors for supporting a healthy immune system.

Stress can impair immune function by altering production of white blood cells, increasing markers of inflammation and even affecting how some genes are expressed. Linalool’s anti-anxiety effects seem to help counteract the body’s stress response.

Linalyl alcohol also seems to have certain antimicrobial properties, helping defend the body against infections. This can be useful not only for your body, but also in certain cleaning and personal care products.

Furthermore, it has antioxidant properties and even possibly anticancer potential.

4. Helps soothe irritated skin

Is linalool safe for skin? It depends on how it’s used, but usually it’s beneficial for skin health because it fights inflammation and harmful bacteria.

For example, lavender oil can be applied to skin rashes to soothe redness, itching and other symptoms. Plus it helps treat issues like razor bumps and razor burn, diaper rash and so on.

Simply combine three drops of pure lavender oil with a half teaspoon of coconut oil, and apply it to the problem area three times per day for rash relief. Lavender oil can also be mixed with grapeseed or almond oil and gently massaged onto the skin.

5. May benefit those with epilepsy and neurological conditions

Linalool is sometimes used to help in the treatment of neurological diseases, including epilepsy (spontaneous seizures,), because of its anticonvulsant properties. Research has suggested that this terpene can alter brain chemicals involved in excitability and muscle contractions, such as levels of glutamate and acetylcholine, potentially helping stop seizures and protect the brain from damage.

Studies also have revealed that linalool may hold promise for helping those with Alzheimer’s disease by fighting cognitive impairments caused by inflammation, brain plaque and other cellular abnormalities, as shown in research on mice. This animal study found that inhalation of linalool over a three-month period helped with memory, learning and spatial awareness among mice with neurodegenerative disorders.

6. Natural bug repellent

The scent of linalool is known to deter mosquitos and act as a natural bug repellent. For example, lavender essential oil and peppermint oil can be used to repel bugs both indoors and outdoors.

Oils containing linalool can be diffused or applied to the skin if mixed with a carrier oil to help repel mosquitos and other insects, preventing bites and rashes.

Dosage and how to use

Linalool is utilized in various forms:​

• Essential oils: Extracted from plants like lavender and basil, used in aromatherapy and topical applications.
• Pure linalool: Isolated compound used in research and product formulations.
• Synthetic linalool: Manufactured for use in fragrances and flavorings.​

Applications include:​

• Aromatherapy: Inhalation of linalool-rich essential oils to promote relaxation and reduce anxiety.
• Topical use: Applied in diluted form for its anti-inflammatory and analgesic properties.
• Ingestion: Used as a flavoring agent in foods and beverages; however, ingestion of concentrated forms should be approached with caution and under professional guidance.​

Pure linalool is described as having a fresh, clean, mild, light floral odor with a slight citrus scent.

The most common ways to ingest linalool are through aromatherapy or inhalation of lavender essential oil. You can benefit from the aroma of lavender oil by:

• diffusing it in your home
• adding some to homemade lotions or massage oils
• spritzing some of your sheets and pillow
• inhaling it from the bottle

The same goes with peppermint and cinnamon oils, which also contain terpenes. Use only several drops of essential oil on your skin at a time, mixed with a carrier oil.

Here are ideas for making DIY recipes that contain linalool and other beneficial compounds, such as terpenes and antioxidants:

• DIY Rash Cream with Aloe & Lavender
• Homemade Lavender Lotion
• Homemade Bug Spray

Risks and side effects

Is linalool toxic to humans? Linalool is a “generally recognized as safe” substance approved by the U.S. Food and Drug Administration as a direct food additive (synthetic flavoring substance) for both human and animal consumption.

That said, it’s important to follow dosage guidelines when using oils or extracts that contain terpenes. If you’re allergic to lavender, rosewood, cinnamon, or other related spices and plants, avoid any products made with linalool.

In some people, linalool can cause some side effects, such as skin irritation, especially when applied undiluted, and allergic reactions.

Remember that essential oils are extremely potent and should only be used in small amounts and according to label directions. They can be used aromatically and topically (per directions) for best results.

If you are taking medications or are pregnant, speak to your doctor about potential interactions before using essential oils.

Linalool is toxic to cats and dogs as well, so avoid using linalool-containing products around pets.

How to avoid synthetic linalool:

When linalool is made synthetically and added to beauty or household products, it will likely be mixed with other chemicals that can cause issues, such as nasal sensitivity, allergies and skin rashes. To avoid this, don’t buy products that list fragrance, parfum, phthalates, DEP, DBP or DEHP as ingredients.

When “linalool” is listed on a label, it’s likely a synthetic, man-made version, not the natural compounds part of a more complex organic essential oil.

Look for products that use organic essential oils when you are looking for a scent. Buying certified organic products also means they’re less likely to include artificial scents (but still read labels).
