AzarcÃ³n por empacho--another cause of lead toxicity.
A new source of toxic lead ingestion has been identified roentgenologically in Mexican-American children and adults. AzarcÃ³n is an orange powder that contains 86% to 95% lead tetroxide (Pb3O4). At least three children have been treated with this substance by folk healers for relief of abdominal symptoms. Other Hispanic medical folklores may include this toxic "remedy."
