Lavandin (Lavandula x intermedia) is a hybrid lavender species commonly used in aromatherapy. Its essential oil contains linalool and linalyl acetate, compounds also found in true lavender (Lavandula angustifolia), which are linked to anxiolytic (anxiety-reducing) effects. The use of lavender oil for anxiety has both a long tradition and a body of scientific research supporting its efficacy, mostly focusing on L. angustifolia. Clinical studies on Lavandin specifically are less common, but some research indicates it may have similar, though generally milder, effects due to its comparable chemical profile.

A few small human studies and animal models have shown that inhalation of Lavandin essential oil can reduce markers of stress and anxiety, likely through modulation of GABAergic neurotransmission. However, the evidence is not as robust or extensive as for true lavender. Systematic reviews and meta-analyses often mention lavender, but rarely distinguish between species, and when they do, Lavandin is less represented. The anxiolytic action is thought to result from olfactory stimulation impacting the limbic system, which is involved in emotional regulation.

Overall, while there is scientific rationale and some preliminary evidence supporting the use of Lavandin for anxiety, the quantity and quality of clinical studies are limited. Thus, the evidence is rated as moderate to low (2/5), and more rigorous studies are needed to establish its efficacy and safety profile for anxiety disorders.
