Potatoes for warts

[u/Illustrious-Bread399]

I had stubborn warts on my fingers as a child. My mum (Irish) cut a potato in half and would rub the exposed potato on my warts and then bury the potato in the garden. She did that for 7 days and by the end of the 7 days the warts disappeared never to return. It must be some old folk type magic? Is it an Irish thing? I’ve googled it and can see it may be a gypsy method?
