Common Poisonous Plants
| While plants add a touch of color and
fragrance to our daily lives they also inject an element of danger into the
lives of our pets. More than 700 plants have been identified as producing
physiologically active or toxic substances in sufficient amounts to cause
harmful effects in animals. Poisonous plants produce a variety of toxic
substances and cause reactions ranging from mild nausea to death. Certain
animal species may have a peculiar vulnerability to a potentially poisonous
plant.
Below is a list of some of the common plants which may produce a toxic
reaction in animals. This list is intended only as a guide to plants which
are generally identified as having the capability for producing a toxic
reaction.
