It is difficult to create a list of poisonous plants. While some plants are outright toxic to anyone who eats or comes in contact with the plant (Jimson Weed, nightshade), others may cause a reaction in some but not in others.The following is a listing of plants normally thought to be poisonous. THE LIST IS NOT COMPLETE. People should not eat plants not grown as food crops — vegetables, fruits, cereal grains. Children should be taught never to eat non-food crop plants.
Poisonous plants vary between animals. Don’t assume that since a bird, squirrel or pig ate a plant with no problems, humans can do the same.
If problems are encountered, or for a more complete list of poisonous plants, contact a doctor or the emergency room of your local hospital. Never hesitate contacting a physician if there is the smallest doubt.
Unless otherwise stated, consider all parts of the plant poisonous.
