Tiegun yam contains saponin. After peeling, there will be a mucus. The protein and diosgenin in it can irritate the skin and cause allergies. Allergies caused by yam mucus generally do not last long and will disappear automatically in half a day or a day. Here are 4 ways to avoid itchy hands:

1. Wear gloves: After washing the yam skin, it is best to wear gloves or put a fresh-keeping bag on your hands before peeling.

2. Steaming and blanching: Use boiling hot water to blanch the skinned yams directly into the water. In this way, the allergens in the yam skin are destroyed, and you will not be allergic if you come into contact with it again. Yam skin is actually very good. It moisturizes the spleen and lungs. It is also good to eat it with the skin after being washed and steamed.

3. Soak your hands in vinegar: Soak your hands in diluted vinegar water for a while before processing.

4. Special peeling knife: A special peeling knife for peeling yam to avoid touching the yam with your hands. It is sold on Taobao.

What should you do if you have itchy hands?

1. Apply vinegar: wash your hands, and apply vinegar on your hands, even between the nails. The itching sensation will gradually disappear after a while, and the acid and alkali will neutralize the itching. .

2. Heating: Roast it on the fire, turn your palms repeatedly to heat your hands, which can relieve the pain and itching. Be careful not to burn the skin. Or soaking your hands in hot water for 5 minutes can also be effective.

3. Soap + liquor: Wash your hands with soap first, then rub some liquor on your hands, and then wash your hands with soap after it evaporates, which can also relieve itching.

4. Fengyoujing: Diluting toilet water or Fengyoujing into water and then washing it repeatedly can relieve the pain.

Finally, in fact, you can directly wash it and remove the hair on the surface, steam it and eat it directly. The skin also has its own effects, which can moisturize the spleen and lungs. There is no harm in eating it. For as long as I can remember, when making yam at home, they rarely peel it. Like yam beans, they just put the skin on and throw it into the millet porridge.
