Yes i have eaten many coconuts with no killing of acaris and also many pineapples with no killing of acaris. (i mean the big worms are still moving after)
I don't think it is a scam, i think the main problem is that the stomach, small intestine, colon and others organs of the digestive system, filter / transform / neutralise the food, drugs, herbs you eat.
So even with the humaworm herbs it is difficult to reach the nearly 10 meters of digestive tube with all the herbs starting components.
Killing a worm outside the body with coconut or pineapple or herb or drug is not the same thing than killing the worm inside the body (where organs filter / transform / neutralise the food, drugs, herbs).
Maybe a sea salt flush with herbs or coconut or pineapple will be more efficient ? The components will directly be in contact with the worm ? I'll try that after the humaworm cure.
