Abstract

Research conducted in 2003/2004 documented and validated (in a non-experimental way) ethnoveterinary medicines used by small-scale, organic livestock farmers in British Columbia (BC), Canada. Interviews were conducted with 60 participants who were organic farmers or holistic medicinal/veterinary practitioners. A workshop was held with selected participants to discuss the plant-based treatments. This paper reports on the medicinal plants used for fleas in cats and dogs.

Ear problems are treated with Achillea millefolium L., Calendula officinalis L., and Helichrysum angustifolium (Roth.) G. Don. (Asteraceae), Allium sativum L. (Alliaceae), Berberis aquifolium Pursh./Mahonia aquifolium (Berberidaceae), Glycyrrhiza glabra L. (Fabaceae), Lobelia inflata L. (Campanulaceae), Matricaria recutita L., Melaleuca alternifolia L.
