The Effect of Lavender on Stress in Individuals: A Systematic Review and Meta-Analysis.

Study answer

What this study found

Lavender significantly reduced stress overall across the included studies. L. angustifolia appeared to produce greater stress reduction than L. stoechas, and aromatherapy was reported as a particularly effective administration method. The authors concluded lavender may be useful in stress management programs, especially for students, but further research is needed to confirm the findings and refine optimal use.
