Indigenous knowledge of medicinal plants among Dozo hunters: an ethnobotanical survey in Niamberla village, Burkina Faso.

OBJECTIVES: This investigation aims to provide a database of Dozo traditional knowledge of medicinal plants used for the treatment of common diseases.

DESIGN: The study was conducted through individual interviews using a survey form. Data were recorded in a database allowing statistical analysis. Each plant was recorded and documented with a herbarium specimen. Settings/Location & Subjects: The term Dozo refers to great hunters from Burkina Faso, highly renowned for their knowledge of medicinal plants. Niamberla village was founded by Dozo hunters and is currently the residence of many traditional healers. Unfortunately, their indigenous knowledge is not well recorded and may be lost between two generations.

RESULTS: A total of 16 traditional healers were interviewed, giving 89 recipes for the treatment of 37 diseases. The most common diseases are malaria (13%), psychological/spiritual issues (12%), gastric disorders (11%), sexually transmitted diseases (10%), and wounds (8%). A total of 56 medicinal plants have been identified, consisting mostly of trees (44%), shrubs (34%), and herbs (16%).

CONCLUSIONS: The results of this research provide a basis for pharmacological and toxicological investigations and are necessary to preserve the indigenous knowledge of traditional medicine among Dozo hunters.
