There are various Items for use in the Pokemon world. Each of these may not necessarily be available in the campaign you’re playing an may be priced different from campagin to campaign.

Potions:
Potions are a useful way for Trainers to keep their Pokemon in fighting shape without needing to return to a pokemon center every single time they run into an angry wild pokemon. Potions are sold in small, one time use spray bottles that when sprayed on a pokemon, sterilize and heal wounds. Potions are meant for Pokemon use. When used on humans, it will sterilize a wound, but it cannot repair damage tissue and seal wounds. If the entire bottle of Potion isn’t used, it cannot take effect on the pokemon.



Status Ailment:
Pokemon have developed various ways to turn a battle into a one sided fight. By Poisoning, Paralysing, putting foes to Sleep, Burning or Freezing foes, pokemon can ensure victory. However, Status Ailment items can heal specific affliction your pokemon may be suffering. Like Potions, these Items usually come in spray bottles that can be applied on the pokemon’s body to take effect, curing your pokemon and evening the battle once again. While meant for Pokemon, Status Ailment Items will also treat human wounds or at least stabilizes a human’s affliction until they can receive hospital treatment. If the entire bottle of Status Ailment curing item isn’t used, it cannot take effect on the pokemon.


Repels:
Repels can be sprayed on one’s self in order to ward of wilds with a subtle smell that greatly annoys pokemon. It’s best to not make your own pokemon endure the smell while using Repels yourself. Only really desperate, wild pokemon will bother with attacking you when you spray Repel on yourself.
