From the perspective of traditional Chinese medicine, Chinese wild yam is credited with tons of health benefits since it is good at tonifying kidney and spleen. Modern pharmacology finds that it helps improve digestive system, lowers blood sugar and blood pressure, inhibits oxidation and promotes urination. Chinese yam dishes are very popular thanks to their great taste, mild tonic properties and high nutritional value. However, please pay attention when handling fresh Chinese wild yam. It is extremely slimy and its mucilage contains plant alkaloid, which is prone to cause allergy symptoms like itch, upon excessive contact. The flesh will oxidize and turn brown when exposed to air, so soak them in water right after cutting. Doing this will also help get rid of some of the slimy stuff.

You can choose to use black chicken or silkie as it is considered more nourishing.
