European Medical Cannabalism practiced into the 18th Century.
Human fat was supposed to alleviate rheumatism and arthritis, while a paste made from corpses was believed to help against contusions.... For some Protestants,... , it served as a sort of substitute for the Eucharist, or the tasting of the body of Christ in Holy Communion. Some monks even cooked "a marmalade of sorts" from the blood of the dead.
. . . . The assumption was that all organisms have a predetermined life span. If a body died in an unnatural way, the remainder of that person's life could be harvested, as it were -- hence the preference for the executed.... In 1492, when Pope Innocent VIII was on his deathbed, his doctors bled three boys and had the pope drink their blood. The boys died, and so did the pope.When we read about Burundians and Tanzanians murdering albinos to make "medicine" of their victims, we should not forget that European Medical Cannabalism was an accepted practice as late as the 18th Century.
