The use of medicinal plants in Guruve District, Zimbabwe, contributes significantly to primary health care of the people of the area. This paper presents findings of a survey of plants used for the treatment of sexually transmitted diseases (STDs) in the district. Ethnobotanical information obtained from traditional herbalists and other knowledgeable rural dwellers, has revealed 15 plant species belonging to 10 families as medicinal plants used for the treatment of these infections in the area. Six of these are the commonest and most frequently prescribed by the healers. Roots are the most frequently used parts of the plants constituting 53% of preparations while oral administration of extracts is the main method of prescription. Based on the information gathered from the traditional healers, Acacia nilotica (L.) Willd. ex Delile, Cassia abbreviata Oliv. Dichrostachys cinerea Wight and Arn, Solanum incanum L., Vernonia amygdalina Del. and Zanha africana (Radlk) Excell. are the most frequently used plants for the treatment of STDs. The methanol extracts of Cassia abbreviata, Zanha africana and Acacia nilotica showed significant inhibition against Gram-positive and Gram-negative bacteria, while acetone extracts of these plants inhibited most of the species. Generally the water extracts show less activity than acetone and methanol extracts.
