The search for secrets of ancient remedies

Cassandra Quave is a world leader in the field of medical ethnobotany — studying how indigenous people used plants in their healing practices to identify promising candidates for modern drugs.

Cassandra Quave (it rhymes with “wave”) is an assistant professor in Emory’s Center for the Study of Human Health and in the School of Medicine’s Department of Dermatology. She is also a member of the Emory Antibiotic Resistance Center.

The Florida native looks at home in the sweltering heat of South Georgia, standing behind a pick-up truck parked on a dirt road that winds through a longleaf pine forest. She tilts a straw cowboy hat back from her face and waves off a flurry of gnats. Her utility belt bristles with shears and a hunting knife. The unfolded gate of the truck bed serves as her desk, as she wrangles a leafy vine of passionflower into a wooden plant press.

 “The Cherokee pounded the roots of passionflower into a poultice to draw out pus from wounds, boils and abscesses,” Quave says. “Everywhere I look in this ecosystem I see plants that have a history of medicinal use by native peoples. The resin of the pine trees all around us, the fronds from the ferns beneath them and the roots of those beautiful yellow flowers over there — black-eyed Susans — were all used to treat wounds and sores.”
