Blooming Datura

One of my colleagues has this flower in his office. It's Datura innoxia (sometimes erroneously called Datura Meteloides) Datura Meteloides. It contains atropine, a powerful belladonna alkaloid which is an antidote for serin (nerve gas). It's been used in "traditional medicine to alleviate toothache and backache.
