Haemonchosis is one of the common helminthic diseases of ruminants which causes high mortality. Course of infection depends on the worm burden, age and nutrition of the host. The principal feature of Haemonchus species infection is anaemia. Anthelmintics with different modes of action are the necessity of the hour, which has changed the focus to other sources like plants. Screening of medicinal plants for their anthelmintic activity has become great scientific interest. Ethnopharmacological surveys provide the rationale for selection and scientific investigation of medicinal plants. Herbal drugs are extensively used as anthelmintics in the developed world before the era of broad spectrum drugs. Many currently available therapeutic compounds are plant derived or synthetic analogues derived from those compounds. Plants of the genus Artemisia were used against the nematodes Ascaris suum and Toxocara spp. as well as cestodes of poultry. From time immemorial, plant derivatives like Nicotiana tabaccum have been used against Moneizia, Ascaridia and several species of GI nematodes including Cooperia, Haemonchus, Nematodirus and Trichostrongylus. Arecoline and several other alkaloids from the dried ripe seeds of Areca catechu were found to be active against tapeworms in dogs and poultry. Aristolochia species of plant are traditionally used for neatodiasis in India. In this review an effort is made to compile the available reports and studies about the anthelmintic activity and use of different plants especially of Aristolochia with special reference to Haemonchosis.
