Questions people ask
Is lavender tea equivalent to Silexan?
The anxiety result concerns a standardized oral oil. It does not establish an equivalent effect from tea. 2
Does smelling lavender treat insomnia?
The evidence is still unclear; traditional use to aid sleep is not the same as a well-established insomnia treatment. 1 3
How long were oral-oil studies?
The 2019 analysis reported benefit with Silexan 80 mg daily for at least six weeks. This describes research, not a personal dose recommendation. 2
Can it be combined with sedatives?
An interaction is theoretically possible. NCCIH recommends discussing lavender use with a health professional when taking medicines. 1
