Antimatter is a potion item in UnderMine.
The potion's effect will cancel upon being hit once, and is not time-based, unlike many other potions. The effect lasts between floors.
This includes all types of damage. Falling into pits, enemies, bombs, traps, Penance, etc. The potion is extra useful with TRANSMUT3, as the peasant can pull the lever twice, drink the potion, and gain all the lost health back with the third pull.
Antimatter does not negate time-based damage. If the peasant is set on fire from an attack, the first hit is healed but the damage afterwards will not be healed.
Damage negated by 
Nullstone does not activate the effect; damage taken afterwards will trigger the potion's effect.
