Linalool is a naturally occurring terpene found most commonly in lavender and basil. Due to its sweet, floral aroma, it is often used as an additive in several household products like soap and perfume. Several animal studies have implicated this terpene in the potential treatment of various conditions, including depression[1], anxiety[2], stress[3], inflammation[4],[5], and pain[6]. In addition, animal models have demonstrated that linalool may possess anti-convulsant[7], anti-asthma[8], and sedative[9] properties. Human trials have even linked the usage of linalool-rich essential oils to menstrual pain relief[10].
