Huh--not to the herb, Wormwood , It's been killing worms for thousands of years, and I think the ONLY reason that any parasite is getting any kind of 'resistance' to anything is because big pharma is having them genetically modified.
If everyone did a successful parasite cleanse, zapper especially (hard to modify anything enough to avoid being sawed up), the 'medical' industry would crash---it's about the parasites, pretty much.
