Linalool is a naturally occurring terpene alcohol found in various plant species, including lavender, basil, and coriander. It has one of the most recognisable aromas of all the terpenes. Its characteristic lavender scent with a hint of spiciness is common to over 200 types of plants. Linalool has two stereoisomers: (R)-linalool and (S)-linalool, with the latter being more common in nature.

Linalool acts in a number of beneficial ways on the human body. It is known for its calming and relaxation-inducing properties. It may act on the central nervous system and influence neurotransmitters to reduce anxiety and promote sleep. Contemporary studies have also shown that linalool is a powerful anti-inflammatory and analgesic and is being studied as a medicine for cancer patients. Inflammation is a major component in the pain profile of cancers, multiple sclerosis, chronic pain, and arthritis.
