Background And Objective:
Lead poisoning is normally caused by repeated occupational inhalation of lead. However, lead may also be absorbed through the digestive route. Some alternative medical treatments, such as Ayurvedic medicine, can also contain lead and may result in poisoning.
Patients And Method:
We collected cases of lead poisoning related to Ayurvedic treatments attended at the Hospital Clinic of Barcelona.
Results:
Two female patients, aged 45 and 57 years, respectively, who initiated Ayurvedic treatments which involved the ingestion of various medicaments, were included. The first patient presented with anemia and abdominal pain. The lead level was 74μg/dL and free erythrocyte protoporphyrin was 163μg/dL. She was treated with intravenous calcium disodium ethylenediaminetetraacetic acid (CaNa2EDTA) and later with oral dimercaptosuccinic acid (DMSA) with a good evolution. The second patient presented with abdominal pain and a Burton's line. The lead level was 52μg/dL and free erythrocyte protoporphyrin was 262μg/dL. She was treated with oral DMSA and evolved favorably. Lead concentrations in some of the tablets supplied to the patients reached 2,003 and 19,650μg/g of tablet.
Conclusions:
Lead poisoning may result from treatments based on Ayurvedic medicine and may reach epidemic proportions. Health control of alternative medicines is necessary.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
