The Sensitive Plant (Mimosa pudica) has a long history of use in traditional medicine systems, particularly in Ayurveda and folk medicine across South and Southeast Asia. In these traditions, the plant is used for a variety of ailments, including pain relief and the treatment of headaches, especially those thought to be caused by "heat" or tension. Preparations may include infusions, decoctions, or topical applications of the leaves or whole plant. However, the documentation of its use specifically for tension headaches is limited to ethnobotanical surveys and anecdotal reports, rather than detailed descriptions in classical texts.

From a scientific perspective, there is little to no clinical research directly evaluating the efficacy of Mimosa pudica for headache or tension-type headache. Some preclinical studies suggest that the plant exhibits analgesic and anti-inflammatory properties, likely due to its content of alkaloids, flavonoids, and tannins. These properties might theoretically contribute to relief from headache symptoms, but such evidence is indirect and not specific to headache. Thus, the justification for its use in treating tension headaches is based largely on traditional practice and minor preclinical pharmacological findings, rather than robust clinical validation.

In summary, Mimosa pudica is used in traditional medicine for headache relief, but evidence supporting its use for tension-type headaches is weak and largely anecdotal, with a lack of rigorous clinical studies to substantiate these traditional claims.
