Toxicology
• Sulfur has low toxic potential (rat oral LD50 of greater than 5,000 mg/kg), and poses very little if any risk to human and animal health (Extoxnet, 1995)
• When taken orally, it produces laxative action(Extoxnet, 1995;National Library of Medicine HSDB database, 2011)
• It is an irritant of the skin and mucous membranes(Extoxnet, 1995).
• Acute inhalation of large amounts of the dust may cause catarrhal inflammation of the nasal mucosa which may lead to excessive nasal secretions. In addition, trachibronchitis occurs frequent associated with dyspnea, persistent cough and bloody expectoration (Extoxnet, 1995)
• Topical sulfur is keratolytic . . .
