The ethno botanical investigation of medicinal plants used by the Kurichia, Kuruma, Kattunaika, Adiya and Paniya tribes of Wayanad district, Kerala were recorded. One thousand (1000) ethno medicines derived from 500 plants used by the tribal medical practitioners were documented. Of this, 10 species were frequently used for treating various infectious diseases. An informant consensus factor was calculated for 10 species which are being frequently used. The leaf extracts of these plants were screened for antimicrobial activity against Escherichia coli, Staphylococcus aureus and Aspergillus niger. Among the plants screened Garcinia gummi gutta (Clusiaceae) was found to possess highly significant antibacterial activity and significant antifungal activity was observed in Nothapodytes nimmoniana (Icacinaceae) which possess highest antifungal activity. These two species have shown the highest informant consensus factor values.


Key words: Medicinal plants, informant consensus factor, antibacterial activity, antifungal activity, ethno botany.
