Don't know about the Pyrantel Pamoate but I can tell you the UZ zapper works, you must have more than 9 volts and a battery even when new won't work.
I won't have another QXCI/SCIO test until Feb 8th but between my last two the zapper has kept me parasite free. I do still add herbs at key times like Full and New Moons but don't seem to have any die off anymore.
But as I have stated in an earlier post, neither the Parazapper Coffee-Enema (1 week use) nor herbs or even mega CoQ10 killed of the French Hearworm I had. But I sort of knew that because only Bing Lang totally eliminated all my symptoms.
Of course knowing this now a Rife machine could have zapped it, perhaps even one of the prgrammable zappers, but the QXCI/SCIO gives you feedback so if you have access to one it may be worth the money.
