Synopsis

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

Dioscorea nipponica is primarily used in traditional Chinese medicine (TCM), where it is known as "Shan Yao" or "Japanese Yam." In TCM, Dioscorea species are believed to tonify the Lung and Spleen Qi, nourish Yin, and help address conditions such as chronic cough, shortness of breath, and fatigue. The use of Dioscorea nipponica to support the Lung system is based on centuries of empirical practice and is often included in formulas intended to moisten the lungs, stop coughing, and support general respiratory health. However, while there is some pharmacological research on Dioscorea nipponica, most studies focus on its anti-inflammatory, anti-arthritic, and cardiovascular effects, attributed to its steroidal saponins (dioscin and related compounds), rather than direct effects on pulmonary function or lung-specific mechanisms.

There is limited scientific evidence specifically validating its use for supporting lung health or treating lung diseases. Most contemporary studies do not directly address the respiratory system. Therefore, while Dioscorea nipponica is traditionally used to support the Lungs in TCM, the evidence remains primarily historical and experiential, with a modest evidence rating of 2, reflecting strong traditional use but insufficient scientific validation for this particular body system.
