“…However, under controlled experiments, no anthelmintic activity has been demonstrated (Hordegen et al, 2003). In addition, there is a large number of grazing forages, including Lotus pedunculatus and Hedysarum coronarium, whose anthelmintic activity has been shown to be rather inconsistent across the various studies around the world (Niezen et al, 1998;Garcia et al, 2003;Marley et al, 2003;Athanasiadou et al, 2005;Tzamaloukas et al, 2005).…”

The use of medicinal plants for the prevention and treatment of gastro-intestinal parasitism has its origin in ethnoveterinary medicine. Although until recently the majority of the evidence on the antiparasitic activity of medicinal plants was anecdotal and lacked scientific validity, there is currently an increasing number of controlled experimental studies that aim to verify and quantify such plant activity. There are indeed a large number of plants whose anthelmintic activity has been demonstrated under controlled experimentation, either through feeding the whole plant or administering plant extracts to parasitised hosts. However, contrary to traditional expectation, there are also a great number of plants with purported antiparasitic properties, which have not been reproduced under experimental conditions. In this paper, we discuss the source of such inconsistencies between ethnoveterinary wisdom and scientific experimentation. We focus on the strengths and weaknesses of the existing methodologies used in the controlled studies to determine the activity of antiparasitic plants. We discuss issues like the seasonal and environmental variability of the plant composition, and how this can affect their antiparasitic properties and highlight the importance of identifying the mechanisms of action of such plants and the target parasite species. In addition to their antiparasitic properties, medicinal plants may also have anti-nutritional properties, which can affect animal performance and behaviour. For this reason, we emphasise the need for considering additional dimensions when evaluating medicinal plants. We also question whether using similar criteria as those used for the evaluation of anthelmintics is the way forward. We propose that a holistic approach is required to evaluate the potential of medicinal plants in parasite control and maximise their benefits on parasitised hosts. Keywords: bioactive plants, ethnoveterinary medicine, medicinal plants, parasites, ruminants IntroductionFor centuries, medicinal plants have been used to combat parasitism, and in many parts of the world are still used for this purpose. In ethnoveterinary medicine, which draws inspiration from traditional practice, there seems to be a range of plant/s or plant extract suitable for treating almost every parasitic disease of livestock (International Institute of Rural Reconstruction (IIRR), 1994). For example, seeds of garlic, onion and mint have been used to treat animals that suffer from gastro-intestinal parasitism, whereas extracts of the tobacco plant have been used to treat the skin of livestock afflicted with external parasites (Guarrera, 1999). Leaves, dried flowers and oil from Chenopodium ambrosioides, a shrub that originated from Central America and has been distributed around the world, have all been used as anthelmintics since the early 1900s (Guarrera, 1999).Reports from around the world include exhaustive lists of plants that have been reported to have medicinal properties (Hammond et al., 1997;Akhtar et al., 2000;Waller ...

“…The tannin may also decrease the hatching rate of parasite eggs and larval development in faeces. Forage plant species (Marley et al 2003) which contain high levels of condensed tannins include sericea lespedeza (warm season legume), birds foot trefoil (perennial legume) and chicory (leafy perennial). Tropical legumes contain more condensed tannins than temperate legumes.…”

Internal parasite management in grazing livestock

et al. 2012

It is a challenging task to control internal parasites in grazing livestock even by applying multi label and multi directional approach. It is impossible to draw general recommendations to control parasitic diseases due to varied geo-climatic conditions and methods adopted for rearing the livestock in the country like India. In view of increasing incidence of anti-parasitic drug resistance in animals, there is an urgent need to design sustainable parasite control strategy which must include on the host as well as off the host control measures to harvest the maximum productivity from the animal for an indefinite period.

“…Tannins can complex with proteins, reducing available amino acids and resulting in larval death by starvation, or can bind to the glycoprotein-rich cuticle of the larvae, causing death (Athanasiadou et al 2001). Reduction in the number of nematode eggs in faeces of sheep fed tanniferous plants has been shown by Marley et al (2003), Lange et al (2006) and Minho et al (2008). Other hypotheses may explain the in vivo anthelmintic action of tannins.…”

The anthelminthic efficacy in vitro of the aqueous extract of Genipa americana L. leaves was evaluated at final concentrations of 20, 30, 50, 75 and 100 mg (dry matter)/mL through egg hatching inhibition (EHI) tests and quantitative cultures. The observed lethal concentration LC 90 values for hatching and L3 development inhibition were 79.8 and 28.7 mg/mL, respectively. The extract was more effective in larval development inhibition (LDI) than in hatching inhibition. Phytochemical analysis revealed tannins and flavonoids in the extract. The utilisation of G. americana as an anthelminthic may represent a viable alternative to synthetic products, although further studies are needed to verify its in vivo efficacy and to assess its toxicity in sheep.
