 Can TCM practitioners diagnose every illness just by taking the pulse?

A: Pulse-taking has a vital role in disease diagnosis. However, just relying on this will only tell you part of the story. For example, the "rolling pulse" is a usual sign in pregnant women; however it can also be seen in patients who have dampness in their intestines and stomach. 

In order to make an accurate diagnosis, it is necessary to combine the four methods of diagnosis: (1) inspection – observe anything unusual about the patient's appearance; (2) listening and smelling – listen to the patient's voice and notice how they smell; (3) questioning – asking the patient about their medical history and symptoms; and (4) palpitation – finding out the pulse rate and its nature as well as by pressing the skin, hands, feet, chest and abdominal areas to check for pathological changes. A comprehensive view of all the body's symptoms and signs has to be undertaken before any diagnosis can be made.
