For the residents of the Pine Ridge reservation in South Dakota, mainstream medical care is often supplemented or replaced by a host of traditional practices: the Sun Dance, the yuwipi sing, the heyok'a ceremony, herbalism, the Sioux Religion, the peyotism of the Native American Church, and other medicines, or sources of healing. Thomas H. Lewis, a psychiatrist and medical anthropologist, describes those practices as he encountered them in the late 1960s and early 1970s. During many months he studied with leading practitioners. He describes the healers-their techniques, personal histories and qualities, the problems addressed and results obtained-and examines past as well as present practices. The result is an engrossing account that may profoundly affect the way readers view the dynamics of therapy for mind and body.
