“…However, these drugs may not be readily available to smallholder farmers, or to remote pastoralist communities. The misuse of these synthetic anthelmintics has led to the development of anthelmintic resistance (Lans & Brown, 1998). Cassia alata leaf is credited for the treatment of hemorrhoids, constipation, inguinal hernia, intestinal parasitosis, blennorrhagia, syphilis, and diabetes in humans (Adjanahoun et al, 1991).…”

“…In developed countries, gastrointestinal parasites are controlled by using commercial anthelmintics whereas in the developing countries, traditional methods of helminth control largely remain dependent on medicinal plants. The misuse and poor formulation of synthetic drugs for many decades have led to the development of anthelmintic resistant (AR) worm strains or population (Waller 1997;Lans and Brown, 1998;Law et al, 2003). Also, the use of disinfectants to control free living stages of the parasites is harmful to non target organisms and to the environment (Dunn and Greiner, 1997).…”

In vitro ovicidal and larvicidal activities of extracts of the seeds of Embelia rowlandii were investigated on unembryonated and embryonated eggs, first and second stage larvae of Heligmosomoides bakeri. Three different extracts were prepared with distilled water (DW) and 95% ethanol. The organic extract was first diluted with 3% Tween and then distilled water added to obtain five different concentrations (625, 1250, 2500, 3750 and 5000 µg/ml). These concentrations were put in contact with eggs and larvae of H. bakeri. One milliliter of each extract at different concentrations and controls were added to 1 ml solution containing 30 to 40 eggs or 10 to 15 larvae (L 1 and L 2 larvae) and distributed in different Petri dishes. Both eggs and larvae were incubated at 24°C and exposure time was 48 h for fresh (unembryonated) eggs, 6 h for embryonated eggs, 24 h for L 1 and L 2 larvae, respectively. Distilled water and 3% Tween were used as negative controls in the bioassay. These placebos neither affected egg development, hatching nor larval survival. A significant effect was obtained with cold water extract (CWE), hot water extract (HWE) and ethanolic extract (EtE) and differences were observed depending on the parasitic stage. CWE, HWE and EtE inhibited embryonic development (60.5, 82.5 and 46.9%) and hatching (85.8, 74.1 and 41.0%), respectively at 5000 µg/ml. All the three extracts killed both L 1 larvae (84.5, 86.0 and 61.2%) and L 2 larvae (65.2, 83.7 and 33.3%) respectively at 5000 µg/ml. These in vitro results suggest that extracts of E. rowlandii possess ovicidal and larvicidal properties.

“…Plant extracts have been found to have antioxidative (Osawa et al, 1995), antimutgenic (Soni et al, 1997) and imunomodulatory (Antony et al, 1999). A number of pharmacological activities of Curcuma longa have been reported which include nematocidal (Kiuchi et al, 1993), anti-inflamatory (Ammon et al, 1993), internal and external injuries (Lans and Brown, 1998) and food additives on aflatoxininduced mutagenecity and hepatocarcinogenecity (Soni et al, 1997). Information regarding anticoccidial acticity of turmeric is very limited.…”
