Willow, particularly the bark of the white willow tree (Salix alba), has a long history of use in traditional medicine for pain relief, including headaches. The primary active constituent is salicin, which is metabolized in the body to salicylic acid—a compound chemically related to aspirin (acetylsalicylic acid). Several clinical studies and systematic reviews have investigated willow bark for pain conditions, most notably low back pain and osteoarthritis, with some data extrapolated to other types of pain, including tension headaches.

Although there is scientific rationale for using willow bark for tension headaches—given its analgesic and anti-inflammatory properties—direct high-quality clinical trials specifically targeting tension-type headache are limited. However, some small studies and anecdotal reports suggest benefit, and its mechanism of action aligns with that of aspirin, which is effective for mild to moderate headache pain. The World Health Organization and European Medicines Agency recognize willow bark as a traditional herbal medicine for the relief of minor articular pain and headache, further supporting its use.

Overall, the evidence supporting willow bark for tension headache is moderate, with mechanistic plausibility and some clinical backing, but lacks robust, high-quality trials directly addressing this specific indication. Users should also be aware of potential side effects and contraindications similar to those associated with aspirin use.
