Cassia fistula, commonly known as the golden shower tree, has a long-standing history in traditional medicine systems such as Ayurveda and Unani. In these practices, it is primarily used for its laxative, anti-inflammatory, and detoxifying properties. Traditional Ayurvedic texts sometimes include Cassia fistula as part of polyherbal formulations for conditions involving joint pain and inflammation, such as amavata (a concept similar to rheumatoid arthritis). The rationale in traditional medicine is often based on the plant’s ability to reduce 'ama' (toxins) and its mild anti-inflammatory effects, which are believed to indirectly support joint health and comfort.

However, direct scientific validation for the use of Cassia fistula specifically for supporting the joints is limited. Most contemporary studies focus on its laxative effects, antimicrobial activity, or general anti-inflammatory properties in laboratory models. There are a few preclinical studies suggesting that extracts of Cassia fistula possess anti-inflammatory properties, but these are not specifically targeted at joint disorders or clinically validated in humans for joint support. Therefore, while its use for joints is rooted in traditional practice, robust scientific studies confirming its efficacy for this body system are lacking.
