>>44843574Reminder this is based on game logic not anime.
Items are symbolic and work based on how the pokemon is made to feel.
for example
A balloon can hold up a giant mon by making the mon simply feel light and floaty when they hold it and see it.
Berrys actually have no medical value they just taste good to pokemon and eat good food makes them feel better making them literally get better.
Items that actually induce literal physical effects can only be used by humans on pokemon or be activated by machines most of a pokemon's power comes to it mentally which is why two charzard can be built exactly the same but one with a good trainer will hit much harder.
