    Is it caused by an irritant substance or by the roughness of the surface? Either way disposable gloves would help, but in the latter case they would have to be more robust than the typical ones for food use, so it makes a difference

  • Do you mean blisters start forming on your hands? If so, is it from the friction of working the knife on those roots? Dec 3, 2018 at 18:57

The colocasia root (also known as the taro root) has calcium oxalate near the surface under its skin. This makes it toxic to eat uncooked and can irritate the skin.

Common methods to avoid skin irritation are oiling the hands (which isn't working for you), peeling them under running water, which rinses off the irritants quicker, and lastly is wearing gloves.

I would recommend getting a box of food grade latex gloves, that should keep your skin from coming into contact with the irritants. Doing it under running water also wouldn't hurt.
