Of all the instances of cannibalism found in human history, no one quite practiced it like some in China used to. In these cases, cannibalism came in the form of eating mellified flesh for medicinal purposes. In 16th century China, mellification was a way for elderly people nearing the end of their lives to donate their body to science. The idea, originally derived from an Arabic recipe, was that they could turn their bodies into medicine that would be ingested by their descendants to alleviate ailments like broken bones. The process of mellification was a gruesome one. In short, it consisted of very slowly turning one’s body into a mummified human candy bar. And that’s not even the worst part — for mellification to be the most effective, the process started while the person was still alive.
