First large-scale ethnobotanical survey in the province of Uíge, northern Angola.

While the study area is large, no significant influence of the distance in regard to species composition in traditional healer's concepts of the respective village was pointed out. Although several plants were just mentioned by women or men, respectively, no significant restriction to gender-specific illnesses in medical plant use could be found. Merely concerning the age of informants, a slight shift could be detected. Visual representation of the ethnobotanical study in Uíge, northern Angola.
