Why does my tongue hurt after eating yam? Please tell me why.

Traditional Chinese medicine has no way of explaining it. This is because of an allergic reaction.

The mucus contained in the skin of yam contains plant alkaloids. Contact with it may cause yam allergy and itching in some people. Direct contact should be avoided during handling. Therefore, raw yam cannot be eaten, and raw yam will contain a certain amount of toxins. Eating raw yam can easily cause poisoning, so do not eat raw yam.

Yam mucus has many benefits:

The main component of mucus is yam polysaccharide, which has antioxidant and immune-increasing effects. Yam polysaccharides are easily soluble in hot water. For iron-bar yams with high starch content and suitable for staple food, the best way to eat them is to cut them into sections and steam them or boil them into porridge. For vegetable yams with high water content, the juice should be collected before serving to allow more polysaccharides to adhere to the yams and avoid dissolving in the vegetable soup.
