This study addresses ways Khmer refugee elders utilize traditional herbal medicine with Western biomedicine in the treatment and prevention of illnesses. Methods include semi-structured and informal interviews with elders and family members, semi-structured interviews with local health care providers and Khmer physicians, and participant observation of everyday life and actions specific to health beliefs and behaviors. Data reveal a reliance on traditional medical ideology for understanding and treating illnesses. Utilizing a traditional ideology, Khmer elders rely heavily on traditional treatments and use Western biomedicine as supplements or adjuncts to traditional preventive and curative practices. This research has important implications for health care providers who treat SEA elders, especially for diet and treatment of chronic illnesses often associated with aging populations.
