Health Benefits
1. Lipid metabolism and cecal fermentation
In the study to examine the effects of raw Chinese yam (Dioscorea opposita), containing resistant starch (RS), on lipid metabolism and cecal fermentation in rats. Raw yam (RY) and boiled yam (BY) contained 33.9% and 6.9% RS, respectively, showed that raw yam is effective as a source of RS and facilitates production of short chain fatty acid (SCFA), especially butyrate, in the rat cecum. In addition, RY has a plasma-cholesterol lowering effect, possibly due to the inhibited release of VLDL(1).
2. Biocontrol agent
In the study to investigate whether a plant chitinase can be used as a biocontrol agent instead of chemical fungicides by spraying chitinase E (family 19; class IV) from a yam (Dioscorea opposita Thunb) alone or together with beta-1,3-glucanase directly onto the surface of a powdery mildew infecting strawberry berries and leaves, indicated that this kind of plant chitinase might be safe and biodegradable biocontrol agent for use instead of conventional fungicides(2).

4. Insulin resistance
In the study of the effects of Dioscorea opposita (huai shan yao, HSY) on dexamethasone-induced insulin resistance were investigated in vitro and in vivo, showed that D. opposita extract reduced significantly the blood insulin and glucose levels in dexamethasone-induced diabetic rats. In vitro, HSY significantly enhanced insulin-stimulated glucose uptake in 3T3-L1 adipocytes. Moreover, HSY increase the mRNA expression of GLUT4 glucose transporter in 3T3-L1 adipocytes(4).
