Yes mustard has feeling powers. I told my daughter to go to the fridge to get the cold mustard i applied it to her finger and wrapped it with tissue, because we didn't have band aids. A few seconds she told me that the burn was subsiding and until it completely stopped. The mustard for burns is for small burns and it works wonders and the thing is there is less discoloration. By morning there was no pain at all. She was a happy camper. I hope this tip helps anyone in need of a burn remedy.
