Before Snake Oil, There Was Millenia Old Human Flesh

In the Middle Ages, in Europe, “thousands of Egyptian mummies preserved in bitumen were ground up and sold as medicine”.[34] The practice developed into a wide-scale business which flourished until the late 16th century. This “fad” ended because the mummies were revealed to actually be recently killed slaves. Two centuries ago, mummies were still believed to have medicinal properties against bleeding, and were sold as pharmaceuticals in powdered form (see human mummy confection).
