Lavender (Silexan)
Commonly used for
SleepStressFocus
What is it? / Overview
Silexan modulates voltage-dependent calcium channels in a manner similar to some anti-anxiety medications, without the sedation or dependence risk of benzodiazepines seen in clinical trials.
How is it used? / Administration
Form: Silexan (the specific proprietary lavender oil capsule studied in clinical trials) -- distinct from aromatherapy/topical lavender oil, which has much weaker evidence
Typical dose studied: 80 mg/day (the dose used in Silexan clinical trials)
Timing: Once daily, any time
Silexan is the only lavender preparation with meaningful RCT evidence -- generic 'lavender oil' capsules not standardized to this specific preparation have not been tested the same way and shouldn't be assumed equivalent.
How well does it work? / Evidence
~ Moderate evidence
Who should avoid it?
Interacts with: Sedatives, benzodiazepines, or other CNS depressants -- additive drowsiness
Already taking it? Mild GI upset (burping, nausea) is the most common side effect, often reduced by taking with food.
