Poison Resistance, with the beloved Poisonous Potatoes!

Poisonous Potatoes have no use by now, except them being thrown away.

But what if you could make them useful, by eating them? Listen me out...

In Medieval Ages, queens, kings or any high class member of a group, had the suggestion to eat or drink a small quantity of poison every day, in order to "evolve" the liver into a much better poison absorber.

This could be made in Minecraft! With Poisonous Potatoes! Something like an invisible Poison Resistance.

The effect doesn't make you unvulerable to the poison, but will increase your chance of survival! For instance: you know that poison can't actually kill you? It will always leave you to half of a heart. The Poison Resistance will increase the hearts remaining:

0 Poisonous Potatoes eaten = Half of a heart remained

1 - 3 Poisonous Potatoes eaten = Two hearts remained

4 - 6 Poisonous Potatoes eaten = Half of the health bar remained

and so goes on... The effect will be permanent until you die, but it will not remove the poison effect or reduce the duration of it. You can still have it but won't make you loose too much hearts. Wither effect, drowning and hunger will not be affected by this Resistance, and you will still receive the damage from them.
