A little numbness in yam may be caused by eating the skin of the yam, undercooking or allergy symptoms.
1. Eating the skin of the yam: The main components of yam skin are alkaloids and saponins. If the yam is not carefully peeled, there will be yam skin on the flesh of the tuber, and ingesting yam skin can cause numbness of the tongue.
2. The yam is not cooked: yams contain a certain amount of tannin. Ellagitannins are complex polyhydroxypolyphenols that have some physiological activity but inhibit certain physiological functions in the body. These components can make the tongue feel astringent and numb, which can be eliminated after sufficient heating. Therefore, when eating not fully cooked yam, the tongue will feel numb.
3. Allergy: Saponin, alkaloids and mucin contained in yams are all allergens. People with allergies may experience allergic symptoms when eating, and when allergic, the mouth and tongue will feel numb.
If eating yam tongue numbness suggests that patients rinse with water to reduce the discomfort of the tongue, if the symptoms are serious, please consult a doctor in time and follow the doctor’s instructions for treatment.
