This has three meanings, this disease, this evidence, this cause of treatment to save people, pay attention to its basic disease diagnosis, modern medical examination and laboratory tests have great reference value for Chinese medicine! For example, inflammatory bowel disease, patients are often in pain, if the diagnosis is clear, must be added to Western medicine treatment with Chinese herbal medicine, in order to reduce side effects and enhance the effectiveness! If patients have early symptoms of malignancy, they must be examined first and be able to be treated surgically, and never delay the treatment by taking Chinese herbs all the time! This is the present disease, that is to say, the disease diagnosis is also very important! How to judge this evidence, which is the evidence in the diagnosis and treatment? Very often, the symptoms are only the external manifestations, how to identify and find out the underlying core of the evidence, depends on a lot of clinical practice experience! For example, damp-heat, everyone is talking about damp-heat, what conditions can cause damp-heat? This is what the doctor should focus on, the four diagnoses together, clear investigation, according to the time and place, according to the individual! Only by finding out the root cause of the disease can we get rid of it! The root cause is the factor that leads to the development and aggravation of the disease! For example, in spleen and stomach diseases, diet, emotion and climate are the three most important factors! Dietary control is far more effective than taking drugs! So, even though you need to take medication in severe cases, you still need to strictly control your diet in general! Otherwise, the previous work is lost!
