Going back hundreds of years, powdered mummies were a popular remedy used to treat various ailments. Many physicians between the 12th and 18th centuries believed the ground-up bones and remains of ancient mummies had healing properties. The mummy powder could be ingested for pain or applied as a topical medicine for wounds and many other ailments. However, from the early 20th century, the use of the powder became a controversial practice, with most deeming it unsavoury.
