Terpene Linalool (S)-Linalool_molecule


Terpene Linalool or Linalool molecule is a simple terpene alcohol. There are plenty ways to obtain natural linalool. It has been discovered and isolated in different plants – something around two hundred of them. Amongst the plants, the Lamiaceae plant and herb family is a common source. Lamiaceae plant and herb includes mints and other scented herbs. Another established readily available source is the Lauraceae plant family, which includes laurels, cinnamon, and rosewood. If you want more viable sources, try the Rutaceae family, which contains citrus plants.

If you live in the tropics, you will find good quantities of linalool in birch trees and several different plant species that are found in tropical and boreal climate zones. Although they are not technically plants, some fungi also produce linalool as well. The Environmental Protection Agency has approved the use of linalool as a flavor agent, pesticide and scent. It is used in the production of a wide variety of bath and body products and is commonly listed under ingredients for these products under many names including beta linalool, linalyl alcohol, linaloyl oxide, p-linalool and alloocimenol.

It is usually found in many plants – about two hundred of them. The common sources are the Lamiaceae plant and herb family which comprises mints and other scented herbs. Linalool is present in two major stereogenic forms that occur naturally. This means that chemicals are mirrored copies in terms of their composition. The two forms are known as coriandrol and licareol. Coriandrol is a form of linalool commonly found in plants. It can be found in coriander seeds which are used in the production of essential oils. Licareol, on the other hand, is a form of linalool found in plant sources such as lavender, sweet basil, and laurel. This form is generally very useful a scent agent in different products. Human responds to different scents. The licareol has a woody lavender scent while coriandrol has a sweet floral scent.

It can also serve as an effective insecticide. This is because its vapors have been shown to be effective against fruit flies, fleas and cockroaches.



Linalool is a colorless liquid with a pleasant and mild odor. The odor is so faint that it is only detectable when molecules of linalool are mixed with ether gas or air. However, mixing them is also responsible for making them volatile. It is volatile in the sense that the smell receptors in the nose can be activated by just sniffing them. It has been naturally found and isolated in many essential oils like lemon, cinnamon, ylang-ylang, spearmint, rose, and tangerine. As was noted earlier, its distinctive smell is soft and sweet.

Medicinal Properties

Linalool is useful in combating Alzheimer’s disease. It is proven to reverse the histopathological hallmarks of Alzheimer’s disease. It also restores cognitive and emotional functions through an anti-inflammatory effect. Recent studies also suggest intake of linalool can reduce lung inflammation caused by cigarette smoke to a significant level. Linalool is a pivotal antecedent in the formation of Vitamin E. It has been used both in the treatment of psychosis and anxiety, and also as an anti-epileptic agent.

It is a non-cyclic monoterpenoid and has been described as having floral and lavender undertones. As such, a variety high in linalool creates calming, relaxing effects when administered.

For centuries, people have been using Linalool to help them sleep and relax from a busy day. This is because it reduces the anxiety caused by THC.  Studies also suggest that the use of linalool can boost the immune system; can reduce lung inflammation significantly; and can reinstate cognitive and emotional function (thereby making it useful in the treatment of Alzheimer’s disease).

As the Ma, J., Xu et al study shows, the use of linalool may to a very large extent lessen lung inflammation caused by cigarette smoke by blocking the carcinogenesis induced by benz[α]anthracene. Benz[α]anthracene is a component of the tar that is generated by the burning of tobacco. The result of this study indicates that limonene may be helpful in reducing the harm caused especially in the lungs by inhaling cannabis smoke.

As stated above, the intake of linalool boosts the immune system. It does this by directly activating immune cells through specific receptors and/or pathways. The findings of the Sabogal-Guáqueta et al study indicates that to a large extent, intake of linalool may reverse the histopathological (the microscopic investigation of organic tissues to detect the presence of diseased cells and tissues in very fine detail) hallmarks of Alzheimer’s Disease. This could restore cognitive and emotional functions through an anti-inflammatory effect.

As regards acceptable usage, the Environmental Protection Agency has given its approval in its use as a flavor agent, pesticide and scent. It is commonly found in a variety of shampoo, lotions, soaps, sanitary pads and detergents as a perfume. It is responsible for the sweet or minty floral scent in them. It is now used in the production of a wide variety of bath and body products. In these products, it is usually listed under ingredients as linalyl alcohol, linaloyl oxide, beta linalool, p-linalool and alloocimenol.

Its vapors have been shown to be effective against fruit flies, fleas and cockroaches making it an effective insecticide. Insecticides produced from linalool are very effective in controlling pests such as cockroaches and fleas. Because of its non-toxicity to humans and animals, it is a very healthful alternative to toxic insecticides. The insecticide can be used anywhere with fear of danger to humans and animals
