This disease is characterized by principal deficiency and secondary excess. The cases with agglomeration of dampness and heat or stagnation of toxic materials and blood stasis belong to excess; those with deficiency of liver yin and stomach yin, deficiency of qi and blood, deficiency of spleen yang and kidney yang or deficiency of liver yin and kidney yin belong to deficiency. Excess complicated with deficiency is usually seen during the progress of the diseases. Therefore eliminating pathogenic factors and supporting healthy qi is the treatment principle. Damp heat and excess of blood stasis are common at the early stage.

In TCM, a disease or a symptom might be caused by one pathogenic factor, even two or three pathogenic factors. When diagnosing a disease or a symptom, TCM doctors must follow the principle of "Syndrome Dfferentiation", and then "Suit the Remedy to the Case". In order to gain a more definite and valuable diagnosis, it's important and necessary for the doctor to learn the detailed health information of the patient, including his/her disease duration, age, sex, height, weight, family history, urine, stool, diet, sleep, sweat, energy, mood (emotion), as well as the tongue conditions and the palm conditions, etc. If you would want our expert to create a TCM diagnosis, you're welcome to contact us.
