The illegal wildlife trade is the major cause for global loss of diversity. In Southeast Asia regions and particularly in Vietnam, the consumption of wildlife products is mostly driven by the demand for food and traditional medicinal products. However, consumers’ motivations are poorly understood. In this study, we use mixed social science approaches and social network analysis to understand the social network influence on the consumption of bear bile through gift-giving practices in Hanoi and Nghe An. The study also provides a deeper understanding of how bear bile is consumed as gifts and the current information on bear bile usage. We found that 97.5% of all interviewees have given or received bear bile and the most common occasion for gift-giving is during visits between closed social circles of family and friends. Other reasons for giving bear bile include illnesses, gratitude, drinking among males, and ulterior motives.

Individuals across Cambodia depend on the use of natural products in Traditional Khmer Medicine (TKM), a traditional medicine system in Cambodia that has been practiced for hundreds of years. Cambodia is rich in fauna and flora species, many of which have been, and continue to be, traded domestically for traditional medicine use. Combined with other known exploitative practices, such as snaring for wild meat consumption and international trade in wildlife, domestic trade in wildlife medicine threatens populations of regional conservation importance. Here, we provide an updated understanding about how TKM is practiced in modern times; how TKM practices are transmitted and adapted; and roles of wildlife part remedies in TKM historically and presently. We conducted semi-structured interviews with TKM practitioners in Stung Treng, Mondulkiri Province, and at the National Center for Traditional Medicine in Phnom Penh, the capital of Cambodia. TKM is generally practiced in the private sector, and is mostly informal, without enrollment in any academic training. TKM practitioner roles commonly involve collecting, preparing, selling, and advising on medicine, rather than providing direct treatment. Over half of the interviewed TKM practitioners (57.6%) were still prescribing wildlife parts as medicine over the past 5 years, with 28 species of wild animals reported. Lorises and porcupine were the wildlife products cited as being in highest demand in TKM, primarily prescribed for women’s illnesses such as post-partum fatigue. However, the supply of wildlife products sourced from the wild was reported to have dropped in the 5 years prior to the survey, which represents an opportunity to reduce prescription of threatened wildlife. We suggest that our results be used to inform tailored demand reduction interventions designed to encourage greater reliance on biomedicine and non-threatened plants, particularly in rural areas where use of biomedicine may still be limited.
