If you rename a poisonous potato to "Potato" using the anvil it wont poison you anymore.

I thought if i were to rename a Poisonous Potato to a "Potato" it would still poison you

The Poison Potato didn't poison you anymore

1. Obtain Poisonous Potato
2. Place Poisonous Potato in Anvil
3. Rename Poisonous Potato to Potato
4. Eat the Potato
5. Not be Poisoned
