The Elven Remedy (エルフの特効薬, Erufu no Tokkōyaku) is an item which appears in Suikoden IV.
The Elven Remedy was a much valued potion created from the droplets that dripped inside the Great Elven Tree. It was said to grant something approaching eternal youth to anyone who imbibed it.
During the Island Liberation War, the remedy was stolen by the leader of the forces fighting against the Kooluk Empire but it would be revealed that the remedy stolen was fake, switched by the elves for poison.
