In Minecraft, when we take damage we usually have to get our hunger bar to full, use a potion, or eat a golden apple to regain our health.
Have you ever even thought about the advances in medicine that industry and technology have brought us?
This idea of mine would be in the game as a non-placable object(much like food), and is used in a similar fashion. When you have taken damage, simply retreat, break out your bandage(or first aid kit which would restore more health), and patch yourself up!
This object would ONLY restore health points, the hunger bar remains unaffected

recipe: first aid kit/box, heals 8 full hearts, for near death situations. Once used it must be refilled in a similar fashion as the CF sprayer
