Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Dioscorea oppositifolia, also known as Chinese yam or nagaimo, has a long history of use in traditional medicine systems, particularly in Traditional Chinese Medicine (TCM), where it is called "Shan Yao." In TCM, Dioscorea oppositifolia is primarily used to tonify the spleen and stomach, support digestion, and address symptoms such as poor appetite, loose stools, and fatigue. It is also sometimes used in herbal formulas that aim to relieve nausea and vomiting, especially when these symptoms are thought to arise from "spleen deficiency" or related digestive imbalances.

However, there is limited direct scientific evidence supporting the use of Dioscorea oppositifolia specifically for treating nausea and vomiting. Most of the validation for its use in this context comes from traditional herbal practice and centuries of historical usage, rather than from modern clinical trials or pharmacological studies. Some related Dioscorea species (such as Dioscorea villosa, or wild yam) have been investigated for gastrointestinal effects, but evidence remains inconclusive and is not directly applicable to Dioscorea oppositifolia. Thus, while its inclusion in formulas for nausea and vomiting is rooted in tradition, robust scientific validation is currently lacking.

In summary, the use of Dioscorea oppositifolia for nausea and vomiting is justified by historical and traditional use rather than strong scientific evidence.
