Lavender (Lavandula angustifolia) has been traditionally used for its calming and anxiolytic effects, but recent scientific research also supports its use in the management of anxiety disorders. Several randomized controlled trials (RCTs) and systematic reviews have evaluated the efficacy of lavender oil, particularly in the form of oral supplements (e.g., Silexan), for reducing symptoms of generalized anxiety disorder (GAD) and subsyndromal anxiety. Meta-analyses indicate that lavender oil can significantly reduce anxiety symptoms compared to placebo, with efficacy comparable to some standard anxiolytics but with a more favorable side effect profile.

The proposed mechanisms involve modulation of neurotransmitter systems, particularly by interacting with voltage-dependent calcium channels and inhibiting serotonin reuptake, which may contribute to its anxiolytic properties. Inhalation of lavender essential oil has also been studied, with some trials showing acute reductions in anxiety in clinical and dental settings. However, oral administration appears to have the strongest evidence base.

Guidelines from some European medical authorities recognize oral lavender oil as a potential option for mild to moderate anxiety. While not a replacement for conventional therapy in severe cases, lavender is supported by both traditional use and moderate-to-strong scientific evidence for anxiety relief, justifying its role as an adjunct or alternative in certain situations.
