Geoffrey Abbott, professor of physiology & biophysics in the UCI School of Medicine, is the senior author of a study on botanical folk medicines published recently in Proceedings of the National Academy of Sciences. He and his colleabues tracked the relationship of the human KCNQ5 potassium channel – known for its regulation of vascular smooth muscle tone – to genetic and culturally diverse herbal remedies traditionally used to reduce blood pressure, such as lavender, fennel seed and chamomile. In this interview with UCI's Lilibeth Garcia, Abbott says the future of medicine may just rest in the molecular secrets of ancient cures.
