When scraping taro and yam skin, your hands will itch when touching taro juice. Here I will introduce three ways to relieve itching: 1. When your hands itch because of scraping taro skin, if you put your hands on the fire, you can stop itching. However, when using this method, care should be taken not to burn the skin of the hand. 2. Use a washbasin to hold some clear water, add a little vinegar, and use it to wash your hands after stirring evenly, which can also relieve itching. 3. When your hands feel itchy because of scraping taro skin, you can rinse them with clear water first, then wipe off the water stains, apply a little wind oil and gently wipe them, and the itching will be removed.
