Full Heal clears status ailments from a player's Active Pokémon in a single Item play. The original Base Set wording individually named Asleep, Confused, Paralyzed, and Poisoned, while Expedition Base Set introduced the umbrella phrase 'Special Conditions' after the Burned condition was added, and Rebel Clash later rephrased it as the Pokémon 'recovers from' rather than simply no longer being affected.
Full Heal first appeared in Base Set in 1999 with art by Keiji Kinebuchi, reprinted through several Japanese Gym Theme Decks and Base Set 2. Takashi Yamaguchi illustrated the HeartGold and SoulSilver printing, and 5ban Graphics and Yoshinobu Saito handled the Black and White through Sword and Shield era printings, while Keiji Kinebuchi is credited on the retro Evolutions reprint. It reprinted in the Japanese Pokémon VS expansion with new artwork by the same artist before the Expedition Base Set version updated the card's wording to the Special Conditions umbrella term.
Full Heal is named for the video game item that removes all status conditions from a Pokémon, the equivalent of the TCG's Special Conditions. Full Heal's Base Set print was reprinted across several Japanese Gym Theme Decks and both Half Decks of the Japanese Intro Pack Neo before Expedition Base Set updated its wording, and it later returned as a retro card in Evolutions, first released in Japan's Expansion Pack 20th Anniversary subset.
