Can a drug made from a weed cure cancer? Researchers and scientists are currently searching for an answer to that question, and they are one step closer after a new study showed that it destroyed tumor cells in mice. Scientists at the Johns Hopkins Kimmel Cancer Center and Danish researchers designed this novel anticancer drug to travel undetected through the bloodstream until activated by specific cancer proteins. The drug, derived from the weed from a weed called Thapsia garganica, has been shown to destroy cancers and their direct blood supplies while sparing healthy blood vessels and tissues.
