sentences:  The ancient tombs of Egypt and the deserts could not meet the European demand for the drug mumia, so a commerce developed in the manufacture and sale of fraudulent mummies, sometimes called "mumia falsa".The Italian surgeon Giovanni da Vigo (1450–1525) defined mumia as "The flesh of a dead body that is embalmed, and it is hot and dry in the second [grade], and therefore it has virtue to incarne [i.e., heal over] wounds and to staunch blood", and included it in his list of essential drugs.The Swiss-German polymath Paracelsus (1493–1541) gave mummia a new meaning of "intrinsic spirit" and said true pharmaceutical mummia must be "the body of a man who did not die a natural death but rather died an unnatural death with a healthy body and without sickness".
