A chemical in the poisonous
Mediterranean weed Thapsia garganica — known as "death carrot" by
Arab nomads — was found to kill tumor cells in mice, according to scientists at
the Johns Hopkins Kimmel Cancer Center. The anti-cancer drug G202, derived from
the weed, travels through the bloodstream until activated by cancer proteins.
It won't attack healthy blood vessels and tissues. The researchers treated 29
patients with advanced cancer and are planning a second trial to test the drug
in people with prostate and liver cancer.
