Ages before the dawn of modern medicine, wild animals were harnessing the power of nature鈥檚 pharmacy to heal themselves. Animals of all kinds鈥攆rom ants to apes, bees to bears, and cats to caterpillars鈥攗se various forms of natural medicine to treat and prevent ailments. Hear about apes who swallow leaves to dislodge worms, sparrows who use cigarette butts to repel parasites, and bees who incorporate sticky resin into their hives to combat pathogens.
