Īfter hunting down and killing Rudjek, the nomarch of the nome and a member of the Order of the Ancients, the Medjay Bayek of Siwa was taken to Nitria by Nefertari, the chief healer of the village, when she found Bayek injured near the Bent Pyramid. The most important source for natron during the 1st century BCE was the village of Nitria in the middle of Saqqara Nome. It could also be used to disinfect wounds and wash stubborn stains, like blood. The cutis revealed radiological signs of direct interaction with the natron in the form of covering and possibly permeation.' (Stephanie Panzer, Farzad Borumundi, Johann Wanek, Christina Papageorgopoulou, Natallia Shved, Giovanni Colacicco, Frank Ruhli.In ancient Egypt, natron was highly valued due to its importance in the mummification process, and funerary rites. Evaluated tissues revealed different radiological changes during the experiment, which altogether led to preservation of the tissues without radiologically indentifiable destruction. Their conclusion states 'Radiological findings showed a regular, controlled and effective dehydration by the applied natron without detectable putrefaction. The limb was dehydrated by the natron and without atrophy.

CT and MRI scans were performed throughout testing and the results found were supportive of what we believe of mummification in ancient Egypt. They received a lower limb from a donor post-mortem and mummified it with artificial natron in the same processes and recipes shown by ancient Egyptians. Members of the Department of Oral and Maxillofacial Surgery from Paracelsus Medical University, and the Institute of Anatomy from the University of Zurich teamed up in research on the artificial mummification of human tissue by natron.
