Tongue diagnosis is an important part of syndrome differentiation and treatment in Traditional Chinese Medicine. Improper diet before seeing a TCM doctor can cause abnormal tongue coating, affecting the accuracy of disease diagnosis. Therefore, attention should be paid to diet before seeing a TCM doctor:
1. It is not advisable to drink milk or soy milk. Because milk and soy milk can easily make the tongue coating white and greasy, leading to misdiagnosis.
2. It is not advisable to eat grapes, bayberries, dark plums, etc. Because grapes, bayberries, dark plums, etc., can easily make the tongue coating black, leading to misdiagnosis.
3. It is not advisable to drink coffee, eat egg yolks, oranges, or yellow pills (such as Vitamin B2, Vitamin B Complex, Furazolidone, etc.), so as to avoid making the tongue coating yellow and causing misdiagnosis.
4. It is not advisable to eat walnuts, melon seeds, peanuts, etc. Because these high-fat foods can make the tongue coating white and greasy, easily leading to misdiagnosis.
