Roundworms hatch in the lungs. This is why your saliva is testing positve. They live in the intestines and are not easily seen in regular bowel movements.
The hatching in the lungs is what is causing your upper respitory problems.
Parasites eat when you eat. This is why Humaworm is to be taken 30 minutes before you eat, you want to feed them "poison" first.
You feel them more when you are still, as in going to sleep. Much like a pregnant woman will feel her baby move more when she is still.
You may not have ascaris roundworms, you might have whipworms or hookworms. Both of these are roundworms, hatch in the lungs but both of these can cause leaky gut.
Candida infections go along with parasite infections.
Toxins from parasites can cause adrenal problems and hormonal problems.
Regular Humaworm is fine for the first round. I would recommend the Humaworm and Hu-Mana-Tea first followed by the Candida Cleanse and the tea. You will also need a lung cleanse.
