Biological activities of lavender essential oil.

This review found some scientific support for lavender's traditional uses—like calming effects, antibacterial and antifungal properties, and wound healing—but the evidence is mixed and often contradictory. The researchers flagged a major problem: studies used different types of lavender oil and inconsistent methods, making it hard to know what actually works. Bottom line: lavender probably does *something*, but we need better-designed studies to know exactly what.
