Young plants may contain more or less of some constituents than mature plants.Climate and soil influence the synthesis of some chemicals.Plants contain chemicals that may exert toxic effects on skin, lung, cardiovascular system, liver, kidney, bladder, blood, central and peripheral nervous systems, bone, and the reproductive system.Contact dermatitis and photosensitivity are common skin reactions with many plants.Gastrointestinal effects range from local irritation to emesis and/or diarrhea.Cardiac glycosides in the leaves or seeds of many plants cause nausea, vomiting, and cardiac arrhythmias in animals and humans.
