Hello, it is a very common phenomenon to feel itchy hands when touching yam. This is because yam contains a saponin component, which can cause allergic symptoms such as skin redness, swelling and itching when people come into contact with it.

Why does it itch when you touch yam?

Yam is rich in mucus, and there is a saponin component in this mucus. People who come into contact with it will experience allergic symptoms such as skin redness, swelling and itching. Some people will develop allergic symptoms soon after being exposed to this mucus, while others may not feel uncomfortable until 3-4 days later. Some people return to normal soon after cleansing their skin, while others may have worsening symptoms and even need to see a doctor.

What to do if your hands are itchy after touching yam

Apply vinegar

If your hands are itchy after touching yam, you need to wash your hands first and then apply vinegar on your hands. It usually doesn’t take long. The itching sensation will disappear after treatment, which is due to acid-base neutralization.

Roast over fire

You can also try to bake your hands on the fire.

Soak in hot water

Or soak your hands in hot water for a while, which can have a certain relief effect. This is because saponins are afraid of heat.
