I already mentioned mebendazole for worm infection. Many try using herbs, but the herbs(wormwood, green Black-Walnut , cloves) often aren't strong enough to solve the problem. Some are also concerned about the toxicity of Wormwood , so a large dose can't be used. You could use large doses of ginger and turmeric, which are very non toxic, and seem to be rather toxic for parasitic worms.
