a disease involving skin eruptions (see attestations)
-zahuatl = a suffix that points to cutaneous eruptions
During the matlalzahuatl epidemic of 1805 in Cuauhtlalpan, the Nahuas resisted being treated in hospitals, preferring to treat themselves. "These efforts included ritual bloodletting and curative treatments, including massages and herbal remedies, including the árbol del Perú (cinchona). They also, of course, bathed in temazcales."
