Treatment
From Final Fantasy Wiki
Treatment (ちりょう, chiryou) is a command ability in Final Fantasy VIII. It works by casting an Esuna-spell effect to one party member, removing all status ailments. The main difference with the spell, however, is that this ability can be used even when the player character is Silenced. It also does not remove any magic from your stock.
Treatment is learned from the Guardian Force Siren for 100 AP. It could also be learned by any GF with the item Med Kit, provided there's a space for the GF to learn this ability. If you are out of room for it, the item Amnesia Greens can be used to forget an ability and free up a spot.
