poisonous plants
plants which contain specific chemical poisons, although they may not be identified. They are a different group from plants which cause illness if eaten in very large amounts or have physical qualities that cause illness, e.g. clover in bloat, tree loppings in omasal impaction. There is a third group of plants, those that are only intermittently poisonous. These form a very large group known to have caused nitrite, cyanide or oxalate poisoning but are valuable plants and are safe if used with care. See also under the names of individual plants or the toxins that they contain.

Patient discussion about poisonous

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. The most important treatment for food poisoning is drinking water. The body loses many fluids and the danger is dehydration. Our body can last longer without food than it can without water, and therefore it is ok to avoid eating as much as you used to for a short period of time until your digestive system can recover. However it is very dangerous to avoid drinking, despite the possible vomiting.At any sign of dehydration (fatigue, dizziness) you should seek medical care. In case your symptoms go on loger than expected you should visit your doctor, because antibiotic treatment may help as well.

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 that occur within 1–6 hours after eating the food, suggest that it is caused by a bacterial toxin or a chemical in the food. During this short "incubation period", microbes pass through the stomach into the intestine, attach to the intestinal walls, and begin to multiply there. Some types of microbes stay in the intestine, some produce a toxin that is absorbed into the bloodstream, and some can directly invade the deeper body tissues. The symptoms produced depend on the type of microbe, but are most commonly vomiting, nausea, fever and stomach aches.

Q. How can I tell if I have food poisoning? I've been having diarrhea and been vomiting for 2 days now. How can I tell if it's food poisoning or anything else?

A. when i got food poisioned i was pooping and throwing up at the same time,it lasted for about 10 hours,
