Tāngwàng River Yam

　　Yam has been regarded since ancient times as an affordable and nutritious tonic due to its rich nutritional content. It can be used as a staple food, a vegetable, or even made into snacks like candied haws. Containing substances such as amylase and polyphenol oxidase, yam aids in the digestive and absorptive functions of the spleen and stomach, making it a balanced tonic food for these organs. Whether there is a deficiency in spleen yang or stomach yin, it can be consumed. Clinically, it is commonly used to treat conditions such as a weak spleen and stomach, poor appetite with fatigue, and diarrhea. Yam is rich in various nutrients that help strengthen the body and nourish kidney essence.

Conditions such as kidney deficiency with seminal emission, excessive vaginal discharge in women, and frequent urination can all be treated with yam. It contains saponins and mucilage, which have lubricating and moisturizing effects, thereby benefiting lung qi, nourishing lung yin, and treating chronic coughs due to lung deficiency and phlegm. Yam also contains mucoprotein, which helps lower blood sugar levels and can be used in the treatment of diabetes, making it an excellent dietary remedy for diabetics. Furthermore, yam is rich in mucoprotein, vitamins, and trace elements, which can effectively prevent the deposition of blood lipids on the walls of blood vessels, thereby helping to prevent cardiovascular diseases and contributing to mental well-being, tranquility, and longevity.
