In TCM it is vitally importantly that one listens to what the client has to say. This is vitally important in all systems of healing, but TCM recognizes how critical it is.
Proper treatment depends on the proper analysis of the underlying root.
TCM healers not only listen to what clients say, they listen and observe the way clients say thing. For example, if speech is rapid, this suggests a problem with Heat. There will be variations based on other factors. For example, in the U.S., people raised in the North, in particular in New York City will tend to speak a lot more rapidly than people raised in the South. These are regional differences that need to be taken into account.
