Although at the time of independence, it was politically incorrect to ban traditional medicine in the public health codes of many West African countries, given the identity values that were being defended, in reality the marginalization of traditional medicine during colonization has continued and persists in an insidious manner. Since true collaboration is the result of the actions of those working in the field rather than legislative texts, the aim of this study is to highlight the possible reluctance of doctors to engage in such collaboration, based on hypotheses such as a lack of knowledge of the history of medical science, the defense of corporate interests, or absolute confidence in science as determinants of their attitudes. Using a methodology that combines both quantitative and qualitative methods, this study concluded that it is through the training curriculum for doctors that a deliberate choice has been made to impose the supremacy of modern medicine, simply by deciding what to include or omit from the teaching programs.
