Common themes in the literature on traditional medicine in Papua New Guinea.

A review of the literature on traditional medical practices and beliefs in Papua New Guinea (PNG) was conducted in order to provide context and background information for the Department of Health's National Policy on Traditional Medicine for Papua New Guinea. The literature review examined accounts that refer to all 19 provinces and 50 different cultural groups. PNG is renowned for its cultural diversity and it was evident in the literature review that many beliefs and practices are specific to particular cultural groups. Many cultural groups adopt unique practices based on their own specific explanations of illness. At the same time, the review identified a number of commonalities in concepts of health and illness, treatment-seeking behaviour and reactions to the introduction of western medicine among Papua New Guineans from different geographic areas. Both the diversity and the commonalities provide context and background for the National Policy that was approved by the National Executive Committee in March 2007 and officially launched in April 2009. The commonalities are pertinent to the policy on a national level while the diversity must be considered when the policy is implemented at the local level. Summarizing the commonalities between different cultural groups illuminates central belief and behaviour constructs relating to health and illness. Ideas and similarities in practice or perceptions relating to traditional medicine in PNG that are common across a number of provinces are the subject of this paper. The most common features include a belief in the power of sorcery, which is universal, the importance of adherence to customary law and the healing power of herbs and incantation. These findings are a working draft of the expected norms of traditional medicine in PNG, which can be tested and refined during the process of implementing the National Policy, which, it should be noted, explicitly excludes the use of sorcery.
