RESULTS: A total of 29 plants distributed into 21 families had found to be used by the 3 Kavirajes interviewed for the treatment of various ailments. 42 different individual sicknesses were claimed to be cured by plants mentioned by the Kavirajes. The Malvaceae family contributed the highest number of plants with four plants, followed by the Amaranthaceae family with three plants, and the Leguminosae and Euphorbiaceae families with two plants each. Leaves were the major plant parts used solely or mixed with other parts forming 33% of total users. This was followed by roots 22%, whole plant 12%, stem and bark, fruit and seeds, and flowers 10% each, and pods, rhizomes, and sap 2% each. Seven plants for skin diseases.
