Chinese medicine diagnosis is based on “look, smell, ask, and cut”. If the patient drank milk or soya milk before the consultation, it will easily cause errors when the doctor looks at the tongue, because milk and soya milk tend to make the tongue white and greasy; if the patient ate grapes, prunes, plums, etc. before the consultation, it will also easily cause misdiagnosis, because grapes, prunes, plums, etc. tend to make the tongue black. Coffee, egg yolk, oranges and yellow pills make the tongue yellow and cause misdiagnosis. The tongue of three inches is a “mirror” that peeps into the internal organs. Consultation is the doctor’s first-hand information for diagnosis, must be detailed and clear answers to the doctor’s questions, but some patients may not remember some of their symptoms, or forget to tell the doctor, which makes it difficult for the doctor’s diagnosis. Drinking alcohol tends to speed up the operation of qi and blood and increase the pulse rate, which affects the diagnosis of the disease. Patients should also not be seen immediately after a meal, as blood flow slows down after a meal. Visiting the doctor after strenuous physical activity (e.g., fast rushing, climbing stairs, etc.) can also affect the doctor’s ability to cut the pulse. Some TCM practitioners will also check the temperature of the patient’s palm while cutting the pulse, so try not to have the patient’s hands artificially heated or cooled during the visit.
