Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lavender (Lavandula angustifolia) has a long history of traditional use for alleviating headaches and migraines, often through inhalation or topical application. In recent years, scientific research has begun to validate some of these traditional uses. Several clinical studies suggest that lavender essential oil, particularly when inhaled, may help reduce the severity and frequency of headaches, especially migraines.

A notable randomized controlled trial published in 2012 found that inhaling lavender essential oil for 15 minutes significantly reduced migraine severity compared to placebo. Proposed mechanisms include lavender's potential to modulate neurotransmitter activity (such as serotonin) and its anxiolytic and analgesic effects. Additionally, lavender is thought to have mild sedative and muscle-relaxant properties, which may further contribute to its effectiveness in treating headaches.

While the number of high-quality studies remains limited and most focus on migraine rather than other headache types, the evidence base is growing. Systematic reviews and meta-analyses generally conclude that lavender oil is a promising complementary therapy, though more rigorous research is needed to establish optimal dosing, delivery methods, and long-term safety. Overall, lavender's use for headache relief is supported by both historical tradition and emerging scientific evidence, warranting a moderate evidence rating.
