經律異相 29.30

29.30

昔有國王。人身驢首。佛語國王。雪山有藥。名曰上味。王往食之可復人頭。王往雪山擇藥噉之。遂頭不改。王還白佛。何乃妄語。佛白王言。莫簡藥草自復人頭。王復到山。山中生者皆自除病。不復簡擇。噉一口草即復人頭（出雜譬喻經）。

Formerly, there was a king who had a human body and a donkey's head. The Buddha told the king: "The Snowy Mountains have a medicine named 'Superior Flavor'. If the king goes and eats it, he can regain a human head." The king went to the Snowy Mountains and selected herbs to eat, but his head did not change. The king returned and said to the Buddha: "Why did you speak falsely?" The Buddha told the king: "Do not choose among the herbs, and your head will naturally become human again." The king went back to the mountains. The things growing in the mountains all naturally dispelled illness; without selecting any further, he ate a single mouthful of grass and immediately regained a human head.
