Carboneum oxygenisatum
Carbon monoxide · Human-made/chemical
Carboneum Oxygenisatum produces a state of narcotic poisoning with anaesthesia, prolonged sleep, and marked coldness, alongside prominent skin changes including herpes zoster and pemphigus along nerve distributions. The anaesthesia is notable in that a slight touch with a hot iron can recall sensibility. There is marked amelioration of chest symptoms in open air.
