Anything can clog your liver... are you finding worms in your stool or feel movement in your body? If worst comes to worst, albenza would be the way to go, but before you waste money and tax your liver even more, try to get a photo so it can be matched up. I'm not sure if the zappers work the way the claim. I almost bought into herbs a d zappers but i have yet to read anything where they actually helped. They cause some peoples worms to scatter all over their body. You want to keep them in your intestines where they're easier to kill.
