In her book, "The Plant Hunter: A Scientist's Quest for Nature's Next Medicines" (Viking), Dr. Cassandra Quave weaves together science, botany, and memoir to tell us the extraordinary story of her own journey. Traveling by canoe, ATV, mule, airboat, and on foot, she has conducted field research in the flooded forests of the remote Amazon, the murky swamps of southern Florida, the rolling hills of central Italy, isolated mountaintops in Albania and Kosovo, and volcanic isles arising out of the Mediterranean—all in search of natural compounds, long-known to traditional healers, that could help save us all from the looming crisis of untreatable superbugs.
