1. Before peeling, wear gloves or put on a fresh-keeping bag to avoid touching mucus.
2. Put on gloves, wash the soil of yam and put it in hot water for scalding. After decomposing the mucus of yam, you can easily peel off the skin with a knife.
Before peeling, put some vinegar on your hands and peel them again, so it won't itch.
How to stop itching
1. Soak in hot water (the temperature you can bear, it is best not to warm water, which has no effect) for a few minutes, which can effectively relieve itching.
2. It will be better to rub it with edible salt and then soak it in hot water. It must be soaked instead of washed, and the washing is ineffective.
3. It is very effective to rub in rice water.
4. Put vinegar on your hands, remember not to wash it immediately. If you don't like the vinegar smell, you'd better bear it. If it doesn't work, it will continue to itch. Xiaobian really tried it. If time permits, Xiaobian is very recommended to wash it as late as possible, which can completely relieve itching. This principle should be the effect of acid-base neutralization reaction.
5. When I was a child, I also encountered this problem when peeling taro. My mother said to roast it on the fire, flip the palm repeatedly, and let the hands be heated to decompose the phytoalkaloids that penetrated into the hands. It is really effective, but you must be careful not to get burned.
6. If the above conditions are not allowed, you can also try cleaning with soap.
Special tips
If one's fingers itch after shaving yam, don't scratch it. Regardless of the severity of allergies, don't scratch your hands covered with glue all over your body, otherwise, the skin where the glue sticks will itch.
