Sinapis arvensis (wild mustard) has a history of use in traditional and folk medicine for various ailments, including joint pain and inflammatory conditions such as gout. Traditional uses often involve external applications (poultices or plasters) of mustard seeds or preparations, believed to stimulate circulation and provide pain relief. In some herbal medicine systems, mustard has been used to create warming compresses for affected joints.

However, there is little direct scientific evidence supporting the efficacy of Sinapis arvensis specifically for the treatment or management of gout. The traditional rationale is based primarily on the rubefacient (warming, circulation-stimulating) effects caused by glucosinolates and related compounds present in mustard seeds. These effects may temporarily alleviate symptoms such as pain or stiffness but do not address the underlying causes of gout, such as uric acid buildup or inflammation at the metabolic level.

Overall, while Sinapis arvensis is mentioned in some ethnobotanical sources and herbal traditions for joint complaints, clinical evidence is lacking. Modern herbal medicine references do not emphasize its use for gout, and there are no robust clinical trials validating its efficacy for this condition. Therefore, the support for its use in gout is weak and based primarily on traditional practices rather than scientific validation.
