Two kinds of diagnostic data are introduced in this book: First, diagnostic data on shortcut diagnostic forms. In this form, shortcut means to use one to three symptoms to identify the syndrome of a given disease. As an example, headache with red eyes is normally due to liver fire uprising, and headache with red complexion is due to liver yang uprising. This means red eyes and red complexion are two crucial symptoms that can distinguish between the two syndromes. Again, angry dreams are normally due to liver energy congestion, but bad dreams are normally due to heart gallbladder energy deficiency. This means anger and bad are two crucial symptoms that can distinguish the two syndromes in question. states in Article 2 that the greater yang disease must include a superficial pulse This means that whenever a superficial pulse occurs, it points to a greater yang disease. In the past, the Chinese experts have presented countless data of this kind which are available for us to apply in clinical practice today. For this reason, I have conducted extensive research throughout the years to collect over 30,000 data of the kind mentioned above, and now introducing how to make use of those data in clinical practice, which I call diagnostics and therapeutics strategies. Second, key syndromes diagnostic forms. A key syndromes diagnostic form lists a number of key syndromes each of them includes a number of symptoms. It lists all the important symptoms of each syndrome. In making diagnosis, a doctor just fills out the form and comes up with a syndrome with the highest score, which is easy, speedy, and accurate. Data-based diagnostics and therapeutics may be comparable to evidence-based in Western medicine. In Western medicine, doctors need laboratories to provide evidence before they can treat a patient. By the same token, Chinese doctors needs data for references before they can treat a patient. What data does a Chinese doctor need? If a doctor is treating a patient of stomachache, for example, they need a number of clinical data, such as how many standard syndromes does stomachache has, how many formulas or herbs or acupuncture points or common foods are generally considered effective for stomachache. A doctor could be losing confidence and feeling confused and they could even end up in looking for needle in haystack, so to speak. On the other hand, if doctors have all those data before them, they would be confident and positive. Their task in diagnostics and therapeutics would become little more than a question of multiple choice in choosing the right syndromes and remedies. For this reason, I have conducted extensive research throughout the years to collect over 30, 000 data of the kind mentioned above. and now introducing how to make use of those data in clinical practice, which I call diagnostics and therapeutics strategies.
