Hookworm are most commonly found in the small intestine but first the larva migrate from the skin through the liver and lungs before maturing in the intestine. Hulda Clark
found hookworm in many parts of the body where they were part of disease processes. She advised taking wormwood, green Black-Walnut
and cloves followed by herb mixes which are better at killing roundworms. (Rascal and others).
It will probably take repeated treatments to kill all the larva whether you use drugs or herbs. Has you posted at the Parasite: Drugs Forum?
