Plants clean the air, give out oxygen, provide food, enhance the indoor environment, and bring us closer to the nature. Among the myriad species of plants, many have medicinal properties with incredible healing power, while a few have poisonous elements which can take lives. Plants are classified as poisonous because they result in drastic reactions when people are exposed to them. Right from small allergies, upset stomach aches, to fatal stroke and death, these poisonous plants can have unpredictable reactions. With adequate information and practical knowledge, we can avoid the callous attacks of such deadly plants.
