There's still a lot to learn about the healing power of plants, James Duke points out, but what we do know is already prodigious. Much of that knowledge is gathered in The Green Pharmacy, an A-to-Z guide to that relies on plant-based medicines to cure what ails us. Between the listings, Duke crams personal anecdotes from a lifetime of studying herbs, berries, and bark. For example, he relates how he worried about telling a pregnant niece that ginger could help alleviate her morning sickness because he'd learned from a pharmacologist that ginger could also induce miscarriage. Then he solved the mystery: he'd recommended ginger tea, which contains about 250 milligrams of ginger. The Chinese, he learned, use about 80 times that much to end pregnancies--another testimony to the amazing versatility of these natural medicines.
