How to do Chinese yam itchy hands?

1. Wipe ginger

Immediately after itching, apply some ginger juice to relieve itching quickly. Because ginger contains volatile oil, it can promote blood circulation, warm the body and excite the nerves.

Step 2 fire roast

Bake it on the fire, turn the palm of your hand repeatedly, and let your hands get heated. This will break down the saponin that seeps into the hand. However, when using this method, care should be taken not to burn the skin.

Step 3 put vinegar on it

After itching, you can wash your hands carefully, and then cover your hands with vinegar, even the cracks in your nails. After a while, this itching will gradually disappear! (Cause: acid-base neutralization)

Step 4 freeze

Just put your hand in the refrigerator and freeze it. This small series is not recommended. The effect is not obvious and it is easy to frostbite your hand.
