In Benin, more than 70% of the population continues to use traditional medicine for their primary health care needs. Despite this state of affairs, the country has not yet succeeded in exploiting this endogenous knowledge by developing standardised phytomedicines as evidence-based alternatives or as complementary products to so-called modern medicines. One of the main reasons for the low availability of standardised and qualified herbal medicines is related to the lack of rigour in the development process of herbal medicine, both from a scientific and technological point of view. This is due to the lack of real experts in the field of phytomedicine and phytopharmacy, the absence of a technical research platform for the discovery of drugs based on natural substances; and the low level of collaboration among African countries themselves and with specialists from developed countries. The proposed MINNAGAN project contributes significantly to the modernization of the traditional Beninese medicine sector in order to implement actions useful for the development and integration of phytomedicines into health policy in Benin.
