1, itchy hands after peeling yam. This situation belongs to yam allergy and is clinically considered as contact dermatitis. First of all, these secretions on your hands should be cleaned with water, and then some antipruritic and astringent drugs, such as calamine lotion or glucocorticoid cream, such as mometasone furoate cream and halometasone cream, should be applied externally.

2. If you still have severe itching, you can take oral antihistamines to relieve itching, such as ebastine tablets or desloratadine tablets.

3. However, it should be noted that you can't peel the yam directly by hand next time. You can wear gloves or wash the yam in hot water and cook it for a while to remove this alkaline secretion.
