Linalool, a naturally occurring monoterpene alcohol, has been recognized for its diverse biological activities. This monograph aims to provide a comprehensive review of scientific studies related to the healing potential of linalool, covering its sources, chemical properties, pharmacological activities, and therapeutic potential in various disorders.


Linalool has been widely studied for its potential healing properties, including anxiolytic, sedative, analgesic, anti-inflammatory, and antimicrobial activities. This review discusses the current scientific knowledge on linalool and its potential therapeutic applications.

Sources and Chemical Properties

Linalool is found in various plants, including lavender, basil, and coriander. It is a monoterpene alcohol characterized by a 10-carbon skeleton with one hydroxyl group and a double bond.
Pharmacological Activities

Anxiolytic and Sedative Activity
Linalool has exhibited anxiolytic and sedative effects in vitro and in vivo studies. It modulates GABAergic neurotransmission, which regulates anxiety and sleep (Linck et al., 2010).

Analgesic Activity
Linalool possesses analgesic properties, as demonstrated in various animal models of pain. It has been shown to reduce pain perception by modulating the opioid and glutamatergic systems (Peana et al., 2006).

Anti-inflammatory Activity
Linalool exhibits anti-inflammatory properties in both in vitro and in vivo studies. It inhibits the production of pro-inflammatory mediators, such as nitric oxide (NO), prostaglandins, and cytokines (Held et al., 2015).

Antimicrobial Activity
Linalool has demonstrated antimicrobial activity against various bacteria, fungi, and viruses, including Staphylococcus aureus, Escherichia coli, and Candida albicans (Lorenzi et al., 2009).

Therapeutic Potential in Various Disorders

Anxiety and Sleep Disorders
The anxiolytic and sedative effects of linalool have been explored for their potential use in treating anxiety and sleep disorders. Its ability to modulate GABAergic neurotransmission may help alleviate anxiety and promote sleep (Linck et al., 2010).

Pain Management
The analgesic activity of linalool has been investigated for its potential use in managing various types of pain, such as neuropathic pain, inflammatory pain, and postoperative pain. Its ability to modulate the opioid and glutamatergic systems may contribute to its analgesic effects (Peana et al., 2006).

Inflammatory Disorders
The anti-inflammatory activity of linalool has been explored for its potential use in treating various inflammatory disorders, such as arthritis, asthma, and colitis. Its ability to modulate the production of pro-inflammatory mediators may help alleviate inflammation and improve symptoms associated with these conditions (Held et al., 2015).

Infectious Diseases
Linalool's antimicrobial properties make it a promising candidate for treating bacterial, fungal, and viral infections. Studies have demonstrated its effectiveness in inhibiting the growth of various pathogens and reducing the severity of conditions (Lorenzi et al., 2009).

Safety and Toxicity

While linalool has demonstrated therapeutic properties, it is essential to consider its safety and potential toxicity. Generally, linalool is considered safe when used at appropriate doses and concentrations. However, excessive exposure may lead to skin irritation or allergies in sensitive individuals (Tisserand & Young, 2014). Further toxicological studies are needed to establish the safety profile and determine safe dosages and exposure limits for humans.


Linalool has demonstrated various pharmacological activities contributing to its potential healing capabilities. Its diverse activities highlight the potential therapeutic applications of linalool in multiple disorders, including anxiety and sleep disorders and pain management, inflammatory disorders, and infectious diseases. Further research is needed to elucidate the precise mechanisms underlying its pharmacological effects and establish optimal dosages, formulations, and routes of administration for clinical use. The potential of linalool as an adjuvant therapy in combination with other medications should also be explored to maximize its therapeutic potential.
