secret_potion
SecretPotion is the English name of ひでんのくすり (Hiden no Kusuri; literally, "Secret Medicine"). The medicine, however, is not a beverage. It is a pouch of round pills.
This item appears in two storylines of games of Pokémon:
* In Pokémon HeartGold and SoulSilver, the Secret Potion is used to cure Jasmine (pokemon)'s Ampharos.
* In Pokémon Diamond and Pearl, the Secret Potion is used to heal a flock of Psyduck.
