Ca̧o Gío (Coin Rubbing)

Abstract
Ca̧o gíois the Vietnamese practice of rubbing the skin with a coin to alleviate various common symptoms of illness. The back, neck, head, shoulders, and chest are common sites of application. Although mimicking the lesions of trauma, it is not a harmful procedure, and no complications are known. A survey of 50 Vietnamese living in the United States since 1975 and 1976 has shown marked distrust of American physicians, owing largely to actual or perceived criticism ofca̧o gío. Acceptance ofca̧o gíoas a valid cultural practice will facilitate compliance and adequate medical follow-up. (JAMA1980;244:2748-2749)
