**2. Plants with anthelminthic activity identified from Ghana**

The anthelmintic activity of plant extracts was mostly studied by evaluating their effect on worms after direct exposure for a period of time. Earthworms including *Pheretima posthuma*, *Lumbricus terrestris*, *Eudrilus eugeniae* and *Caenorhabditis elegans* were employed as target organisms due to their anatomical and physiological similarity to the human intestinal round worm, ease of availability, adaptability to laboratory conditions and ease of handling.
