Inspection is observation by the doctor, using his eyes, of the systemic and regional changes in the patient’s vitality, colour, appearance and excretions. Auscultation and olfaction (listening and smelling) is listening to the patient’s speech, respiration, and cough, and smelling the odours of the patient.

Inquiring is asking the patient, or the patient’s companion, about the conditions associated with the illness in order to understand the pathological process. Palpation includes feeling the pulse, and palpation of different parts of the patient’s body.

The Eight Principles describe the eight basic categories of syndromes – namely, Yin and Yang, exterior and interior, Cold and Heat, and deficiency and excess- used to analyze the location and nature of diseases, and the relative strength of the pathogenic factors and antipathogenic Qi.
