Adzuki bean (Vigna angularis) has a long history of use in traditional East Asian medicine, particularly within Chinese herbal medicine, for the management of edema and related conditions. In traditional Chinese medicine (TCM), adzuki beans are considered to have diuretic properties, which means they are believed to promote urination and thus help reduce the accumulation of excess fluids in the body—a key aspect of edema. The beans are often used in decoctions or porridges to "drain dampness" and support kidney function, both of which are central to TCM approaches to treating fluid retention.

However, while these traditional uses are well-documented in historical texts and continue to influence dietary and herbal practices, there is a lack of robust scientific evidence specifically validating adzuki beans for the treatment of edema. Some modern studies have noted the bean's nutritional profile (fiber, minerals, antioxidants) and mild diuretic effects in animal models, but these findings are preliminary and not conclusive for edema treatment in humans. Therefore, the primary justification for using adzuki bean in edema is grounded in tradition rather than scientific validation.
