“…Following this basic technique, several medicinal plants such as Albizzia lebbek Bentham (Mimosaceae), Allium sativum Linnaeus (Liliaceae), A. santonica Linnaeus (Liliaceae), Cardiospermum halicacabum Linnaeus (Sapindaceae), Coriandrum sativum Linnaeus, Cucurbita mexicana Damm (Cucurbitaceae), Neurolaena lobata Linnaeus (Asteraceae), Perilla frutescens Linnaeus (Lamiaceae), Spigelia anthelmia Linnaeus (Loganiaceae), Spondias mombin Linnaeus (Anacardiaceae), Polyalthia suaveolens Engler & Diels (Annonaceae), Vernonia amygdalina Linnaeus (Asteraceae), and Zingiber officinale Roscoe (Zingiberaceae) have already been documented to show anthelmintic activity against different nematodes of veterinary importance (Akhtar et al, 2000;El Garhy & Mahmoud, 2002;Iqbal et al, 2003;Boonmars et al, 2005;Fujimaki et al, 2005;Ademola et al, 2005Ademola et al, , 2007Eguale et al, 2007;Adedapo et al, 2007). A closely related species of Acacia used in the present study, A. auriculiformis Cunningham extract, reportedly caused significant activity against the nematode Dirofilaria immitis Leidy of dogs (Chakraborty et al, 1995), the bovine nematode Setaria cervi Kunth (Ghosh et al, 1993) and a cestode Hymenolepis diminuta Sturdevant (Ghosh et al, 1996). Feeding of A. karoo Hayne (Leguminosae) leaves also caused significant decrease in the fecal egg count of the nematode Haemonchus contortus Rudolphi in goats (Kahiya et al, 2003).…”
