Be careful what you touch, and what you eat. Some vegetation can snuff out your life as surely as a venomous snake. There are hundreds, if not thousands, of poisonous plants in the world, and some of them are deadly.

In 2014, a gardener on a country estate in the UK mysteriously died of multiple organ failure. The cause of his death remains unclear, but an inquest heard evidence suggesting he had been killed by a popular flowering plant, a member of the buttercup family.

The plant in question, called Aconitum, has blooms said to resemble monk’s hoods. But the plant is also known by other more sinister names; wolf’s bane, Devil’s helmet and the Queen of Poisons.

We are exposed to environmental toxins all the time. Even the simplest of daily routines can expose one to several common pollutants found in the water we drink, food we eat, and air we breathe. While our liver, kidneys and lymphatic system play a major role in removing biologically harmful compounds, our bodies have not evolved to deal with the growing number of toxins we unknowingly interact with every day. Detoxification systems can easily become overwhelmed, causing toxin overload. This happens when your body has taken in more toxins than it can process. When this happens, real damage is imminent.

Warm summer weather means more insects — along with more people trying to enjoy the outdoors while avoiding pesky pests. However, some are more than a mere nuisance. Although bugs are a crucial part of the ecosystem, some small creepy crawlers pose big threats to humans and animals.

When you think of deathly, dangerous bugs, it's a good bet you think of some myth-like monster in some far-flung locale. You know, the Tse Tse fly in Tanzania, or the wandering spider in Brazil. It might feel like the United States is an insect-free oasis—at least compared to Australia, where spiders literally fall like raindrops, by the thousands, in a terrifying phenomenon aptly dubbed, "spider rain." But the unfortunate reality is that dangerous insects are likely lurking in your own backyard.
