THE KOMBUCHA MIRACLE Tea craze that has been steeping the country came to a crashing halt in northwest Iowa last week when a woman there died and another became sick after sipping the brew. A fungus based drink made of yeasts, bacteria, tea and sugar, Kombucha has been hailed as a cure for everything from baldness to AIDS. But after the death-the first linked to the tea-the Iowa Department of Public Health cautioned people about the concoction and began investigating its connection to the illnesses. Not that the warning dissuaded the potion's New Age enthusiasts. "Every Kombucha drinker this side of the Rockies has called to tell us we're screwy in the looey," says Kevin Teale of the Iowa health department. One fan even had a Kombucha mushroom delivered to Teale's desk.
