Once largely dismissed as a leftover fad from the Age of Aquarius, acupuncture, herbal remedies and other forms of alternative medicine are finding their way into curriculums at traditional medical schools -- most recently the University of Pennsylvania. Doctors at Penn are working with Tai Sophia Institute, an alternative medicine school in Maryland, on a program to teach medical students about herbal therapies, meditation and other approaches that are increasingly popular with the public but largely exist outside the realm of mainstream medicine. It will start in August.
