But this ingredient change probably killed more of the nostrum's users than the original narcotics did, since acetanilide not only caused an alarming cyanosis due to methemoglobinemia but was later discovered to cause liver and kidney damage. The occasional reports of acetanilide-induced cyanosis prompted the search for supposedly less toxic aniline derivatives, such
Ethnoveterinary medicine in future may be increasingly linked to discussions and research on ecosystem health. EVM is now increasingly integrated into "participatory epidemiology" which seeks to improve epidemiological surveillance in remote areas and encourage community participation in disease control (Mathias, 2004). EVM is also studied to provide solutions to diseases in which antigen variation has made vaccination unrealistic and drug resistant strains to Western medicines have become prevalent (Atawodi, 2002). The ethnovet.com website is no longer associated with Dr. Cheryl Lans and no longer has content relevant to ethnoveterinary medicine. Ethnoveterinary medicine Ethnoveterinary medicine (EVM) considers that traditional practices of veterinary medicine
