1, bake on the fire. Because the saponins in yam that are easy to cause allergies are more afraid of heat. Therefore, if you are afraid of allergies, you can wash your hands after peeling or cutting the yam, and then bake the yam on the fire to stop itching. Although this method is effective, it is a bit dangerous. Be careful of burns.

2. Wash with vinegar. Pour a small amount of vinegar into the washbasin and soak it in your hands for about 5 minutes, which can destroy the soapy cutin on the epidermis of yam that causes itchy fingers. This method is not dangerous, but the effect is not obvious.

Step 3 put on gloves. To prevent problems before they happen, it is suggested to wear gloves when peeling yam, or put a fresh-keeping bag on your hand to prevent direct contact between your hand skin and mucus.

4. Steam first and then peel. Chinese yam can be steamed and peeled, which will also destroy saponin components and will not cause itching. This method is very good if you want to eat stewed yam or roasted yam.
