Constipation is the correct description of ny inflamation, you have trapped waste which attracts parasites (bacteria/viruses) all caused by diet or contamination, etc.
The anti-plague type herbs help expell waste especially when it has anything to do with the lungs. In theory, there can be no constipation in the body unless the Lymph glands are flowing poorly and they dump into the intestines to be expelled.
As long as we eat wrong foods or too much foods/liquids we risk constipation. Just breathing toxic air also causes similar problems; so in fact, all humans are somewhat in a state of constipation.
If you experience a symptom, then your body has too much waste and it will seek to remove it; or adapt to having it.
Fasting/herbs/water therapy/chiropractor all aid in restoring circulation. Loss of circulation = disease.
