Is Chameleon plant Poisonous

The chameleon plant doesn't have any natural toxins; by itself, it is relatively harmless. However, it is capable of pulling mercury and methylmercury from polluted soil and storing a significant quantity in its tissues without damaging the plant. By the time a human eats the plant, it may have enough of the toxic metal in it to cause mercury poisoning. The highest levels are found in the roots and leaves, followed by the rhizomes and aboveground stems. Mercury is highly toxic even in small amounts, making chameleon plants that grow in polluted soil a significant hazard. Mercury primarily attacks the nervous system. Symptoms of mercury poisoning include tingling or pins-and-needles feelings in the fingers and toes, and around the mouth, gradually worsening tunnel vision, weakness, tremors, loss of motor control, memory problems, loss of hearing, speech problems, and brain damage, especially in infants and small children. Eradicate this plant when it shows up in your yard, especially if you live in the city or are unsure of your soil's quality.
