The classical medicine believes, that the origin of chronically stuffed noses have two reasons. On one hand an allergetic process and on the other hand a deviation of the nasal septum.
Apparently classical medicine is quite right with these statements, however it cannot answer the question, why allergetic processes happen in the nose and the sinus and why often only later in the course of life deviations of the nasal septum arise.
The nasal septum bends increasingly in the course of life, because at older age the muscle tension in the face and nose area increases, which makes the weakest part, the tilaginous septum, give in and get curved.
The highest tension develops due to meridian causes. Here these are the meridians of stomach (Th6 SMT®)/ spleen-pancreas (Th8 SMT® and Th7 SMT®)/ mouth and nose (C4), which runs over the cheek muscles and ends beside the nose over the maxillary sinus.
When you regard the swelling of the mucous membrane in the area of nose - nasal sinusis,these are the vertebrae of the functional circuit lung (Th3 SMT®), large intestine (L1 SMT® and L2 SMT®), nose and mouth (C4). C4 is at the same time the body orifice to the functional circuit stomach (Th6 SMT®)/ spleen-pancreas (Th8 SMT® and Th7 SMT®)/ mouth and nose (C4).
Damages at the corresponding vertebrae, segments and meridians let swell inflammatorily the mucous membranes of the nose and the paranasal sinusis and the such irritated mucous membranes react stronger than it would be the case at healthy people. This heavy reaction of the mucous membrane is called allergy by the classical medicine. If you put in order the spine, the mucous membranes of the nose and the nasal sinus go down and overshooting reactions stop, i.e. the allergetic factor vanishes.
