Coix, also known as Job's tears (Coix lacryma-jobi), has a long history of use in Traditional Chinese Medicine (TCM), where it is commonly called "Yì Yǐ Rén" (薏苡仁). In TCM theory, coix is classified as a mild, sweet, and slightly cold herb that is used to strengthen the Spleen, drain dampness, and promote urination. The Spleen in TCM is not the anatomical organ but rather a conceptual system responsible for digestion, fluid metabolism, and energy production. Practitioners prescribe coix seeds to address symptoms believed to arise from Spleen deficiency, such as poor digestion, loose stools, and edema. The traditional use of coix to support the Spleen is well documented in classic texts and continues to be a common practice in East Asian herbal medicine. However, while there are some modern pharmacological studies investigating the anti-inflammatory, diuretic, and immunomodulatory effects of coix seeds, direct clinical evidence specifically validating its effects on the "Spleen" system as defined in TCM is limited. Most scientific studies focus on its general health benefits rather than its impact on digestive or Spleen function. Thus, the justification for its use in supporting the Spleen body system remains primarily rooted in traditional practice rather than modern scientific validation.
