Linalool. lin·al·o·ol lə-ˈna-lə-ˌwȯl. lī-, -ˌwōl. : a fragrant liquid alcohol C10H18O that occurs both free and in the form of esters in many essential oils and is used in perfumes, soaps, and flavoring materials.
Background:
Linalool was synthesized for the first time in 1919 in the laboratory of Leopold Ružička. The name "linalool" is derived from "linaloe", a type of wood, and the suffix "-ol". It may also be referred to as coriandrol in the food manufacturing industry.
Linalool is found in over 200 plant species, including those from the Lamiaceae (mint and other herbs), Lauraceae (laurels, cinnamon, rosewood), and Rutaceae (citrus fruits) families. It is also present in birch trees and other plants in a range of climates, from tropical to boreal.
Some notable plants that produce linalool include Lavandula, Cinnamomum tamala, Cannabis sativa, Basil, Solidago, Artemisia vulgaris (mugwort), and Humulus lupulus.
Aroma and Flavor:
Linalool is a terpene found in many cannabis strains, and it is known for its distinct floral aroma and flavor. Some describe the aroma of linalool as similar to lavender, with notes of sweet and floral scents. The flavor of linalool in cannabis can also be floral, with some hints of spice and a slight citrus or lemony taste.
Effects and Benefits:
Linalool is a terpene found in many cannabis cultivars, and it is known for its distinct floral aroma and flavor. In addition to its aromatic properties, linalool has been found to have potential therapeutic effects when consumed or applied topically.
Here are some potential benefits of linalool in cannabis:
Cultivars (strains) with Linalool Dominance:
Cautions:
Allergic reactions: Some people may have an allergic reaction to linalool, which can cause symptoms such as skin irritation, rash, or difficulty breathing. If you experience any of these symptoms after using a product that contains linalool, stop using it immediately and seek medical attention if necessary.
Sensitivity to sunlight: Linalool can increase the skin's sensitivity to sunlight, which can increase the risk of sunburn and skin damage. If you are using a product that contains linalool and plan to spend time in the sun, be sure to use sunscreen and take other precautions to protect your skin.
Interactions with medication: Linalool may interact with certain medications, particularly those that are metabolized by the liver. If you are taking medication, consult with your healthcare provider before using linalool-containing products.
Essential oil safety: Linalool is commonly found in essential oils, which can be used for aromatherapy or topical application. However, essential oils are highly concentrated and can be toxic if ingested or used improperly. Be sure to follow the instructions for use carefully and avoid ingesting essential oils unless under the guidance of a healthcare professional.
Pregnancy and breastfeeding: There is limited research on the safety of linalool during pregnancy and breastfeeding, so it is generally recommended to avoid using products that contain linalool during these times unless under the guidance of a healthcare provider.It is important to specify normal concentrations, as some terpenes can cause irritation, allergic reaction, nausea, headache, and/or acute toxic effects at very high doses - but these doses are much higher than you would ever consume in the course of using cannabis products.
Some terpenes can be dermal irritants, so their concentration in topical products needs to be carefully controlled. Guidance from organizations such as the International Fragrance Association shows that safe limits depend both on the type of product and the individual terpene.
The pharmacological hypothesis argues that aromatic compounds such as terpenes affect mood, physiology, and behavior because they interact with the nervous and/or endocrine systems (hormones).
Linalool refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). A colorless oil, linalool is classified as an acyclic monoterpenoid. In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. Linalool has uses in manufacturing of soaps, fragrances, food additives as flavors, household products, and insecticides. Esters of linalool are referred to as linalyl, e.g. linalyl pyrophosphate, an isomer of geranyl pyrophosphate.
