A survey was conducted in southern Punjab, Pakistan, in order to document existing ethnobotanical knowledge by the herdsmen/key respondents about anthelmintics in ruminants. A 3-satge process was used to document the plants being used to treat and/or control helminthes. This paper describes 29 plants to treat helminthosis in ruminants. The main plants used were Lamium amplexicaule L., Mallotus philippinensis Muell., Withania somnifera (L.) Dunal., Azadirachta indica A. Juss., and Citrullus colocynthis (L.) Schrad. A few of these plants have been scientifically validated for their claim by herdsmen on modern lines while majority of them still needs investigations. This documentation could provide a foundation for the scientific study and verification of those plants which merit such study.
