poison /poi·son/ (poiz´'n) 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.poi´sonous
poison [poi′zən] Etymology: L, potio, drink any substance that impairs health or destroys life when ingested, inhaled, or absorbed by the body in relatively small amounts. Some toxicologists suggest that, depending on the dose, all substances are poisons. Many experts state that it is impossible to categorize any chemical as either safe or toxic and that the real concern is the risk or hazard associated with the use of any substance. Clinically all poisons are divided into those that respond to specific treatments or antidotes and those for which there is no specific treatment. Research continues to develop effective antitoxins for poisons, but there are relatively few effective antidotes. Maintaining respiration and circulation is the most important aspect of treatment.
