Oral lavender oil

View my plan →

The short answer

A standardized oral lavender-oil preparation has evidence for anxiety symptoms; aromatherapy is a different intervention.

Evidence and scope: Conditional or population-specific
This status does not grade the ingredient for every goal, outcome, or person.
Important limitation: Benefit depends on the population, formulation, baseline status, and objective; results should not be generalized.
Before deciding: Key concern: Sedatives, pregnancy, hormone-sensitive conditions, and surgery require caution.

01 / PRACTICAL GUIDE

Dose, absorption, and combinations

These are indication-specific reference or studied ranges—not a personalized prescription. Start with the objective, then check the form, label, medicines, and health conditions.

Reference range by objective

Mood symptoms80 mg/day standardized oral preparation; some trials use 160 mg/day

Reference or studied range—not a personalized prescription. The product label or a clinician may specify a different dose.

Dose source ↗

More is not automatically better. A clinician or product label may specify a different amount.

Absorption / solubilityFat-soluble / lipid-based

Fat-soluble or lipid-based. Absorption generally improves with a meal containing fat.

How it is commonly taken

Swallow the studied enteric-coated product; do not ingest essential oil products not made for oral use.

Do not combine casually

Sedatives, pregnancy, hormone-sensitive conditions, and surgery require caution.

Efficacy of oral Silexan in patients with anxiety disorders

Silexan improved clinician- and self-rated anxiety and quality-of-life measures; adverse events and withdrawals did not clearly differ. The result applies to this proprietary oral product, not inhaled lavender or arbitrary oils.

Study design and methods

Design: Individual-patient meta-analysis of 5 double-blind randomized placebo-controlled trials
Population: 1,213 adult outpatients with subthreshold anxiety, mixed anxiety and depressive disorder, or generalized anxiety disorder
Intervention: Proprietary oral lavender-oil preparation Silexan 80 mg/day versus placebo
Outcome: Clinician- and self-rated anxiety, global improvement, quality of life, and adverse events

Funding or conflict note: One author was an employee of Silexan manufacturer Dr. Willmar Schwabe; several authors reported Schwabe relationships.
