A main means for finding whats going on inside a body is pulse taking. So if your acupuncturist stares vacantly for five or ten minutes while she or he touches your wrist there is no reason to be alarmed.
Another important method of diagnosis is by looking at your tongue. The tongue shape, color and coating all give clues to what is happening not only in the digestive tract but in the internal organs and system as a whole. We don’t consider it rude to have people stick their tongue out at us.
