Dioscorea, commonly known as Chinese yam (Dioscorea opposita or Dioscorea polystachya), has a long history of use in Traditional Chinese Medicine (TCM) for supporting the Spleen body system. In TCM, the "Spleen" is considered central to digestion and nutrient absorption (distinct from the anatomical spleen recognized in Western medicine). Dioscorea is classified as a "Spleen tonic," believed to strengthen digestion, boost energy (Qi), and help manage symptoms such as fatigue, poor appetite, and diarrhea.

Historical texts such as the Shennong Bencao Jing and Bencao Gangmu document its use for these purposes. Dioscorea is typically included in classic TCM formulas like Liu Wei Di Huang Wan and Shen Ling Bai Zhu San, both of which are used to support Spleen function.

Scientific research into Dioscorea has focused on its nutritional content and bioactive compounds (such as diosgenin and mucilage), with some animal studies showing potential benefits for gastrointestinal health. However, direct scientific evidence validating its effects on the human Spleen function (as defined in TCM) is limited. Most support for its use in this context remains rooted in tradition and empirical use over centuries rather than robust clinical trials.

In summary, Dioscorea's use to support the Spleen body system is primarily justified by traditional practice, with moderate historical and anecdotal evidence, but limited scientific validation within the framework of TCM.
