Bob Munley says a healthy diet and drinking Kombucha tea helps him cope with epilepsy. And when he saw that no one was making the stuff commercially in Columbus, Ohio, he saw an opportunity. He now makes about 10 gallons of the stuff a day and sells it to local health-food stores and cafes as well as at a local community market. But the Ohio Department of Agriculture says he must stop selling the tea since he brews it at home. Officials say he must move his production to a commercial kitchen, but Munley says he can't afford that.
