If your home is prone to mold, put English ivy plants in several rooms. According to research from NASA, English ivy is particularly efficient when it comes to removing mold spores from the air. And inhaling mold can lead to headaches, nausea and breathing problems like asthma. But in a study, when English ivy was placed in a container with moldy bread, it destroyed 60% of the mold spores in 6 hours! And ALL the spores in 12 hours.
