Critical medical anthropology is a branch of medical anthropology that applies critical theory in the consideration of the political economy of health, and the effect of social inequality on people's health. It puts emphasis on culture histories, rather than purely biomedical and social explanations of analyzing health. It starts with the idea that every essential component of a human being reside in a biological structure. Thinking about health and medical treatment, there is a tendency to naturalize the process of health and illness.
