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.

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.

Q. What are the Symptoms of Food Poisoning? My kid started vomiting non-stop tonight, but has doesn't have a fever. We ate lunch at this new restaurant, could this be related? What are the symptoms of food poisoning?
A. Symptoms of food poisoning typically begin several hours to several days after consumption of contaminated food, and depending on the agent involved (for instance-bacteria), can include one or more of the following: abdominal pain, nausea, vomiting, diarrhea, fever, headache or fatigue. These are symptoms are classicaly "gastroenteritis-like", however when there's a background of eating out a few hours prior to it, it significantly suggests it is a case of food poisoning.
Q. How Do You Treat Food Poisoning? I've been suffering from food poisoning for the last two days, is there a way to treat it? Is there specific food I should avoid?
A. Food poisoning is caused by a variety of foodborne pathogenic bacteria, viruses, or parasites that contaminate food. Usually the body is able to permanently recover after a short period of acute discomfort and illness. During this period it is very important to keep proper hydration, meaning to drink lots of fluids, preferabely water, because a lot of water is wasted in stools and vomiting. It is also recommended to watch your diet during this short period of time, and avoid dairy products and fruit that might cause further abdominal discomfort. Rice and soup are very recommended. Antibiotics aren't used at the first two days because these are usually viral infections, however if it continues, it is recommended to visit the doctor.
