Six treatments for burns in the London Medical Papyrus provide data regarding a volcanic fallout over Egypt. They confirm a previously established scenario linking the medical text to one specific eruption, the one at Santorini in the Bronze Age. One treatment describes the contamination of waters with the ash. Four treatments describe the effects of the ash on the skin. The sixth treatment describes the effect of acid rain following the dispersion of ash in the atmosphere, which triggered weather anomalies. The scenario derived from the medical document, is based on ash from Santorini that sedimented at the bottom of Egyptian lakes, and fits the description of Egypt in the papyrus The Admonitions of an Egyptian Sage. Finally, the scenario explains the nature of first seven biblical plagues of Egypt in light of the aftermath of volcanic ash littering Egypt.
