It’s called giant hogweed, or Heracleum mantegazzianum, and it is extremely dangerous.
The invasive weed might look pretty, but you will instantly regret touching or brushing up against this plant. Part of the carrot family, giant hogweed is capable of burning, scarring, or even blinding you.
What makes it so toxic are the chemicals contained in the sap known as photosensitizing furanocoumarins. When these chemicals come into contact with human skin the result is absolutely horrific. Within just 48 hours, painful blisters begin rising from the skin, which later lead to unsightly scars that can take years to not look hideous.
It can also cause a skin reaction that’s very sensitive to light. Some people who have suffered burns were forced to avoid sunlight for up to six months. If the sap gets into a person’s eyes, it can cause permanent blindness.
Unfortunately, many people don’t realize they come in contact with the plant until it is too late.\
According to the Department of Environmental Conservation, the weed grows in New York, Pennsylvania, Ohio, Maryland, Oregon, Washington, Michigan, Virginia, Vermont, New Hampshire and Maine.
