Herbs don't work on a infestation. They made me horribly ill.
Zappers have their place but they really don't kill parasites. They are great for killing the viruses and bacteria carried by the parasites. I use one daily but I know the limitations. The zappers can't get through all the tissue and the biofilm produced by the parasites
The zapper you have is not adequate to accomplish whole body detoxification. You would have much better results with the $15 zapper found on-line.
It is much more effective. The one you use is also pumping copper and zinc into your system through the pennies. (copper plated zinc) Not a good thing. But all of them have some sort of metal contact. Pick your poison.
I switched to meds from herbs because the herbs did nothing but make me sick. Ivermectin, Albendazole, Fenbendazole are all fairly safe and work light years better than herbs. I wish I had went to the drugs straight away as I think the herbs just made it worse. I still use Green Black-Walnut as a mouth rinse and to kill any worms in my throat or nose. I use Colloidal Silver and Doxycycline. Everything has value you just need to be able to understand what value.
A good investor would not put all their money on one stock. Use what works.
