please try healing clay internally. You can use bentonite, montmorillinite or similar. The clay physically shreds the parasites, cleans the gut, and also gets rid of candida. Add a teaspoon of clay to a glass of water and let it sit for some time until the clay is hydrated. I would take it twice a day, and plenty of fluids.
You can keep up the herbs, as you need at least a month if not longer to kill all stages of the bugs. Homeopathic Cina (try a 100x potency) is also good for worms.
