Amyris essential oil consists almost entirely of sesquiterpenes — principally valerianol, elemol, and eudesmol isomers — which give it a mild, creamy, sandalwood-like character and make it a widely used sustainable fixative in perfumery. Antimicrobial activity has been characterised against multiple pathogens,^[1] and the oil has been shown to promote anaesthetic sedation in experimental models, consistent with central nervous system depressant activity of its sesquiterpene fraction.^[2]
