This is also called phenol. It is to coal-oil (petroleum) what creosote is to tar from wood. Symptoms of poisoning by either carbolic acid, kerosene, or crude petroleum, are those of an irritant narcotic. First there are burning of the mouth, throat, and stomach, pain in the abdomen, vomiting; then great prostration, faintness, coldness; lastly, insensibility and stupor, ending in death. A tablespoonful of the liquid carbolic acid will be pretty sure to cause death, in from half an hour to eight or nine hours. In treatment of this form of poisoning, we must first use an emetic (mustard, salt, or ipecac, with plenty of warm water), and then give the patient large draughts of sweet oil. If that is not on hand, lime-water and milk, freely given, will be likely to do good by shielding the coats of the stomach and bowels from the poison.
