Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Lavender (Lavandula angustifolia) is commonly used to support the "Smell" body system, particularly for its effects on mood, relaxation, and cognitive performance through olfactory pathways. Scientific studies have demonstrated that inhalation of lavender essential oil can influence the limbic system, which is involved in emotion and memory. Research published in peer-reviewed journals indicates that exposure to lavender scent can reduce anxiety, improve mood, and promote relaxation. For example, a 2012 randomized controlled trial found that inhaling lavender aroma reduced anxiety in dental patients. Another study in 2015 reported that exposure to lavender improved sleep quality among college students. The mechanism is believed to involve linalool and linalyl acetate, major constituents of lavender oil, which interact with neurotransmitter systems such as GABAergic pathways, leading to calming effects.
While lavender's benefits via inhalation are well-supported for stress reduction and improved sleep, the evidence for direct effects on the olfactory system itself (such as treatment of anosmia or enhancing sense of smell) is limited. The primary scientific validation pertains to lavender's impact on psychological well-being and autonomic nervous system modulation when the scent is perceived through the nose. Overall, the use of lavender to support functions related to the sense of smell is justified by scientific research, particularly for its anxiolytic and relaxing properties when administered via inhalation.
