Just to debunk anyone's theory that this should work on the monsters too, chemicals react differently to different organisms, like chocalate (even though most people wouldn't consider it a chemical). To humans, it just makes us fat if we eat too much, but it's highly toxic to most other mammalian carnivores, such as dogs and cats.

Lifepowder could work in the same way, just without it being toxic to any monsters or giving them a health boost.
