Evidence Map

What The Sources Report

• Despite its widespread use, the scientific evidence supporting aromatherapy's efficacy remains limited by methodological shortcomings, most notably, a reliance on subjective outcome measures such as patient satisfaction, psychometric scales, and self-reported assessments. [Moyano Pedro Almeida (2026); evidence level 1]
• Systematic reviews and methodological critiques published in recent years explicitly recommend the adoption of standardized physiological parameters (e.g., heart rate, blood pressure, respiratory rate) and biochemical markers (e.g., cortisol, inflammatory cytokines) as primary endpoints (,,). [Moyano Pedro Almeida (2026); evidence level 1]
• Data extraction was performed independently by two reviewers, and risk of bias was assessed using the Cochrane RoB tool. [Pehlivan S (2026); evidence level 1]
• Aromatherapy significantly reduced anxiety (SMD = − 0.46, 95% CI [–0.63, − 0.30], p < 0.00001), pain (SMD = − 1.29, 95% CI [–1.70, − 0.88], p < 0.00001), fatigue (SMD = − 0.79, 95% CI [–1.52, − 0.07], p = 0.03), and systolic (MD = − 3.72, 95% CI [–6.78, − 0.67], p = 0.02) and diastolic blood pressure (MD = − 2.30, 95% CI [–3.67, − 0.92], p = 0.001). [Pehlivan S (2026); evidence level 1]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For lavender stress meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
