This document discusses health seeking behaviors among southern African migrants in London living with HIV. It finds that migrants access both biomedical treatments from the NHS as well as non-biomedical treatments from traditional healers, churches, and herbal remedies. Migrants choose non-biomedical options due to beliefs in their efficacy, familiarity, cultural identity, family influences, and difficulties accessing NHS treatment. However, there are also responsibilities to take biomedical treatments as prescribed and concerns about the safety of mixing treatments. The implications of clandestine use of non-biomedical options on health outcomes and interactions with antiretroviral therapy are discussed.
