Pau d'arc isn't going to kill them..it is for mop up.
Everybody is different...some ppl claim that the trio of herbs did not work for them..some claimed that quassia worked for roundworms, or boswellia and myrrh with piper longum.
There are so many protocols.
There are many to select from..these herbs mentioned do help cleanse the blood,liver and other organs.
Why just kill and not try to heal?
The colon is damaged and it cannot absorb the meds, fact.
The blood/veins are clogged too.
The lungs..that is where some hatch out..elecampane will help and the meds kill the eggs as clove.
These beast protoect their eggs and hide..the casings are hard, their skin has several layers..that makes killing them more difficult.
