Sagefruit

Sagefruit is a plant the Defenders of the Wing use to pacify dragons.

Effect
Like Dragon Nip, sage fruit calms dragons so they do not attack. However, this does not prevent them from protecting those they care about, as demonstrated with Toothless when he saved Hiccup despite still being under the effect.

Trivia

 * A plant that resembles it is seen in Imperfect Harmony. Whether it is sagefruit is unknown.
 * Sagefruit appears the School of Dragons expansion pack Return to Dragon Island. While Eret was aware of the fruits purpose, the Dragons Hunters were not.
