Dissonance Yin-Yang, i.e., the excess or deficiency of either of the two manifests itself primarily in the form of cold and/or heat and deficiency or excess syndromes.In general, excess heat syndromes occur in cases of excess of Yang, and cold by excess syndromes occur in cases of dominance or an excess of Yin. Cold deficiency syndromes occur in cases of failure of Yang, and heat deficiency syndromes occur in cases of deficiency of Yin.In addition, in the course and progression of disease, cold syndromes can manifest as symptoms of false heat, as when the excess of Yin obstructs the Yang, or as manifestations of false cold heat syndromes, where Yang excess blocks Yin. Any inconsistencies and alterations that occur in the process of disease can be framed in terms of Yin and Yang.Therefore, the Zang-Fu organs and meridians are classified according to the Yin and Yang and the Qi and blood.

The functional alterations, the unconformities between Qi and blood and the defensive Qi and nourishing Qi correspond all the lack of harmony between Yin and Yang, which is the underlying cause in all pathological process and is the decisive factor in the onset and development of diseases. The opposition between the pathogenic Qi and anti-patogeno Qi is understood as opposition or conflict between the pathogenic Qi and anti-patogeno Qi to the struggle between the defensive forces of the body and various pathogenic factors.This conflict affects not only the generation of disease, but also its progression and alteration. To some extent, this conflict can be categorized as the main focus of the onset, progression and transformation of diseases.An invasion by pathogenic Qi annihilates the Yin-Yang harmony within the body and cause functional disorders in the meridians and the Zang-Fu organs, creates irregularities of the Qi and blood, and anomalous descending and ascending movements of Qi, resulting in several pathogenic alterations.These disorders manifested mainly as syndromes of deficiency or excess.Excess syndromes occur more likely if there is both too much pathogenic Qi and one on excitation of anti-patogeno Qi.We understand by excess, in this case, a hubris or exaggeration of the pathogenic Qi, i.e.
