Sage oil (Salvia officinalis) has a long history of use in traditional herbal medicine, primarily for its purported abilities to relieve nervous tension, headaches, and related symptoms. Some traditional medicine practitioners have recommended sage oil (often via inhalation or topical application) for headache and migraine relief, based on its reputed calming, anti-inflammatory, and antispasmodic properties. However, there is minimal direct scientific evidence supporting its efficacy for treating or preventing migraine specifically. Most clinical or preclinical studies on sage oil focus on its antimicrobial, cognitive, or mood-related effects, rather than migraine. A handful of small studies and anecdotal reports suggest that certain essential oils, such as lavender or peppermint, may help with headache symptoms, but sage oil itself is rarely the subject of migraine-focused research. In summary, while there is some traditional use of sage oil for headache and possibly migraine, scientific validation is lacking, and the evidence supporting its use for this purpose is weak (rating: 1).
