"I'll hold off on the zapper then. Thanks for the recommended herbs for parasites, do you know of a good formulation that gives all of these?"

There are many. I use Kroeger Wormwood Combination. It takes two bottles for a one month cleanse, but there are only $5-6 a bottle on the net. Some here like Humaworm which has other herbs as well, which is only available at their website. There are other popular products such as Paragone and others. Just make sure it has at least the three main herbs I mentioned.

Liver cleanses? I have not tried them.
