How to heal player when he right click using item

Create a procedure that gives the provided player 4 health points (two hearts), and apply it to the 'when right-clicked in air' event in your item.

How do you make it so that the item removes itself afterwards? Any help is appreciated

Just find the block in the player section that says "Remove "(Whatever Item You Select)" from the players inventory.

Thank you guys for great ideas. I add some important features to code, so you don't waste the item on creative or when entity's health is full (made it for entity healing)
