Lavender oil is a herbal medicinal product obtained from the flowering tops of the plant Lavandula angustifolia Mill. It is commonly used for its calming and relaxing effects, and has been traditionally used to relieve mild symptoms of mental stress and exhaustion, and to aid sleep. Lavender oil is also known for its antimicrobial, preservative, anti-inflammatory, antinociceptive, and anxiolytic properties.

{"Antimicrobial Property": "Lavender essential oils have been used since medieval times in medicine. Bactericidal properties of essential oils were first tested by de la Croix. Various studies certainly indicate the antimicrobial property of lavender mainly due to its chemical composition. Although numerous studies state linalool as the main component for antimicrobial efficacy, some studies suggest antimicrobial efficacy exists even in the absence of linalool or linalyl acetate. Even though the efficacy of lavender essential oils has been seen predominantly against gram-positive microorganisms, few studies have found it otherwise. It has also shown its inhibitory effects in solution as well as vapor form on various fungi. These effects are due to the constituents of Lavender essential oils on spores of the fungi. Linalyl acetate was found to suppress spore formation, while linalool was found to be effective for the inhibition of germination and fungal growth. This property may be utilized in treating candidal infections, which may occur in geriatric patients or immune-compromised patients. Inhibition by lavender essential oils was found to be sufficient to treat disseminated candidosis. Drug resistance has become a nuisance to medical and dental practitioners. Due to this, the antimicrobial properties of herbal essential oils like L. angustifolia may provide an alternative to antimicrobial medications. Independently lavender essential oil may be delivered with hydroxyapatite. The main advantages of this are efficient drug release, elevated stability, protection from interactions, decreased volatility, enhanced bioactivity, and less toxicity. It was found that hydroxyapatite did not interfere with the antimicrobial property of lavender essential oil. In one of the studies conducted to check for antimicrobial efficacy; the lavender essential oil was incorporated in antimicrobial drugs like ciprofloxacin. Ciprofloxacin has been used as an agent of local delivery in dentistry. Study revealed that lavender essential oil potentiated the antimicrobial activity of ciprofloxacin. This may be an effective way to avoid the development of resistance to an antimicrobial agent. The local antimicrobial property may be utilized to develop an effective root canal sealer.", "Preservative": "It has been proven that lavender essential oils can be used as a preservative for strawberries. Herman et al. has studied the use of essential oils in cosmetics.", "Anti-inflammatory and Antinociceptive Properties": "The lavender essential oil shows a significant anti-inflammatory effect. Lavender oil has been used in dermatitis and eczema. In an animal-based study, lavender oil showed anti-inflammatory activity compared to dexamethasone. It has been suggested that the mechanism involved is related to a G protein-coupled receptor or interference in the system of one of the intercellular second messengers. Antinociceptive properties and anti-inflammatory activity are closely related. Often there is the presence of pain along with inflammation. Non-steroidal anti-inflammatory drugs have been amply used in dentistry for nociception. Due to the side effects they carry, alternative pain-relieving strategies are being developed. The lavender essential oil has been tested positive for antinociceptive action. Studies on animals using the formalin-induced pain model show that oral treatment with lavender oil shows considerable pain reduction in the rats. The exact mechanism is not known; however, it seems to be similar to opioid analgesics. Due to this similarity, it may be used to replace opioid analgesics to solve the problem of addiction that comes with these drugs. Nevertheless, lavender essential oil seems to have no effect on the COX pathway. Research is needed to elaborate on this point further. In dentistry, even though this property may be advantageous, its applicability as an antinociceptive and anti-inflammatory agent has yet to be studied.", "Anxiolytic Property": "The fragrance of lavender is probably the most promising property, which has also been amply researched in the field of dentistry. The prevalence of anxiety in dental clinics all over the world is substantial. Behavior management of the patient requires expertise as well as time. Pharmacologically, several options are available to reduce the anxiety, but it may have side effects on the patient and may, in turn, become a costly affair. Recently, dental practitioners have been researching cost-effective and simple ways of behavior therapy. One of the newly accepted therapies is aromatherapy. According to a study conducted at King's College London, the state-trait anxiety score of the patients who were subjected to aromatherapy using lavender essential oil during dental procedures was decreased as compared to those without the therapy showing promising properties of lavender essential oil. In another study, the mood, alertness, calmness, and anxiety were assessed using lavender fragrance against music therapy, in which aromatherapy using lavender fragrance gave superior results. The mechanism of action of this may be attributed to the action of lavender essential oil in serotonin neurotransmission through 5-HT receptors. Studies have also found a correlation between vital signs and aromatherapy using lavender.", "Toxicity": "Toxicity may accompany the use of marketable essential oils. Factors involved may be product management, ingredients, excessive use or inappropriate use, sensitization/anaphylaxis, and lack of scientific evidence. It is wise to know the adverse effects along with their uses. Some of the studies have shown additional side effects of lavender essential oils like contact dermatitis, acute eczema, and facial dermatitis allergic reaction."}
