That parasite cleanse seems rather standard, wormwood, black walnut, and cloves. Is that kit for one month, or just 2 weeks? Some parasite cleanses add a number of other herbs as well such as quassia, and perhaps a tiny bit of male fern. Some cleanses like humaworm add many other herbs. If you do just the 3 herb parasite cleanse, then I suggest that you also eat plenty of raw garlic while doing it. Some well like cleanses sold in the US are Humaworm, Kroeger Wormwood Combination, and Paragone. I don't know if they are available in the UK.
