2 1. Introduction Humans learned about plant toxicity early on, by probably the hard way. When toxicity was high, it was exploited for hunting or for war; when it was moderate, humans learned to watch out for it. Humans learned about plant toxicity early on, by probably the hard way.

4 In common language, toxic plant is equated with poison hemlock, digitalis, belladonna, in other words “ lethal ” plants. Fortunately, the problems caused by the plants in our environment are generally less dramatic. They mostly have multiple facets.

6 Defining exactly what constitutes a poisonous plant is not easy; almost any plant can cause nausea and vomiting or intestinal cramping when enough is ingested. However a suitable definition is that poisonous plants are those which contain specific components that when small quantities are used (via ingestion or just via contact) cause specific biochemical alterations or physiological symptoms.

7 In 1994, the United States poison control centers (AAPCC) recorded 103,616 calls. The magnitude of these figures is an invitation to determine the circumstances of the calls, to evaluate the true consequences of the accidents, and to inventory the plant species at fault.

13 It is well known that many plants produce chemical compounds which cause different reaction for other living organisms, ether in direct contact or by ingestion. It is well known that many plants produce chemical compounds which cause different reaction for other living organisms, ether in direct contact or by ingestion. Primary compounds can be defined as those required for a plant's basic metabolism. Secondary compounds, loosely, are all others. Primary compounds can be defined as those required for a plant's basic metabolism. Secondary compounds, loosely, are all others. Many of the secondary metabolites would be toxic to the organism producing them if allowed to accumulate or become concentrated in living tissues. Many of the secondary metabolites would be toxic to the organism producing them if allowed to accumulate or become concentrated in living tissues.

14 Plants evolved self-protective ways of handling potentially toxic secondary metabolites by: Plants evolved self-protective ways of handling potentially toxic secondary metabolites by: removing them physically into metabolically inactive locations (e.g. bark, vacuoles, roots, etc); removing them physically into metabolically inactive locations (e.g. bark, vacuoles, roots, etc); converting them into non toxic compounds via specific chemical reactions (hydroxylation); converting them into non toxic compounds via specific chemical reactions (hydroxylation); Plants found that secondary metabolites gave them an opportunity for effective defense against attack by herbivorous insects.

15 For years, emphasis was shown mainly on these plant compounds possessing many therapeutically activities.

Poisonous plants are to be found among all types of native plants: algae, fungi, ferns, herbs, shrubs, and trees.

16 Some of our most cultivated ornamentals are extremely poisonous and these plants very common in houses and public buildings. Fortunately, relatively large amounts of most plants are necessary to produce serious or fatal poisoning in man.

17 The majority of the victims in poisoning are children; small children have a great curiosity and will often chew on anything within reach. Much smaller amounts of the toxin are needed to cause very severe or fatal results.

18 The toxic constituents of these plants are determined by different factors such as: stage of the development, climate and other environmental factors, habitat, plant parts, and different varieties of the same species.

25 Our objectives are to increase the awareness of these potential dangers, to aid in the identification of the more common poisonous plants native, ornamental or cultivated in Jordan, and to assist you in the recognition of symptoms and treatment of such cases.
