poison

a substance that, on ingestion, inhalation, absorption, application, injection or development within the body, in relatively small amounts, may cause structural damage or functional disturbance.

Corrosives are poisons that destroy tissues directly. They include the mineral acids, such as nitric acid, sulfuric acid and hydrochloric acid, and the caustic alkalis, such as ammonia, sodium hydroxide (lye), sodium carbonate and sodium hypochlorite; and carbolic acid (phenol).

Irritants are poisons that inflame the mucous membranes by direct action. These include copper sulfate, salts of lead, cantharidin, oxalate raphides, and many plant and insect poisons.

Nerve toxins act on the nerves or affect some of the basic cell processes. This large group includes the narcotics, such as opium, heroin and cocaine, and the barbiturates, anesthetics and alcohols.

Blood toxins act on the blood and deprive it of oxygen. They include carbon monoxide, carbon dioxide, hydrocyanic acid and the gases used in chemical warfare. Some blood toxins destroy the blood cells or the platelets.
