Linalool is a naturally occurring terpene alcohol found in many flowers and spice plants, such as lavender and coriander. Its use for headache relief, particularly tension-type headaches, is primarily rooted in traditional and folk medicine rather than robust scientific validation. Historically, essential oils containing linalool, most notably lavender oil, have been used in aromatherapy and topical applications to alleviate headache symptoms. The rationale is based on the reported calming and muscle-relaxant properties of linalool, which may help ease the muscle tension and stress commonly associated with tension headaches.

Scientific studies on linalool specifically for tension headaches are limited. Some clinical research does exist for lavender essential oil (which contains significant amounts of linalool), suggesting that inhalation may reduce headache severity or frequency, but these studies often do not isolate linalool as the active component. Most evidence is anecdotal or comes from small trials with methodological limitations. A few animal studies suggest linalool has analgesic and anxiolytic effects, which could theoretically benefit those with tension headaches, but direct evidence in humans is lacking.

In summary, while linalool is traditionally used for headache relief and there are plausible mechanisms for benefit, the scientific evidence supporting its use for tension headaches is weak and mostly indirect.
