 A TCM practitioner can use various and even totally different prescriptions to treat the same disease. How do you explain that?

A: First of all, TCM stresses the uniqueness of each patient in the treatment of disease, so the amount and contents of formulas used could either increase or decrease according to the individual. 

Secondly, TCM views what we called a disease representing the entire course of pathological changes whereas a syndrome reflects the pathology of a disease at a certain stage. A TCM syndrome is a complex disharmony pattern of signs and symptoms that manifest at a given stage of the disease. The TCM practitioner treats a syndrome instead of a disease. For example, the common cold or flu has different syndromes according to TCM understanding, such as wind-cold syndrome, wind-heat type syndrome or low-resistance syndrome. As a result, various therapeutic strategies are employed and different prescriptions will be used among patients; this is called treatment based on syndrome differentiation.
