Record of Syndrome Differentiation: Opening the Eyes Wide

If we say that classical prescriptions are too concise and have too narrow a scope, then...

It cannot cover all needs.

Therefore, we recommend rereading Chen Shiduo's "Record of Syndrome Differentiation" from the Qing Dynasty.

"Record of Syndrome Differentiation" is a practical classic of clinical diagnosis in traditional Chinese medicine. The book is divided into more than 100 sections and contains nearly 2,000 prescriptions. It mainly covers internal medicine and miscellaneous diseases, and also includes gynecology, surgery, and ENT.

Unlike the previous two classic works which were written in a textual style, this book elaborates on the differentiation of pathogenesis, essentially expanding the concise passages in the classics into a diagnostic and treatment manual that can be directly applied.

Having a foundation in typhoid fever and the Golden Cabinet Prescriptions before reading this is equivalent to advancing from "learning prescriptions" to "learning syndrome differentiation."

Why should I recommend reading it?

First, it fills in the details of classic dialectical reasoning and solves the problem of "not knowing how to distinguish".

The texts in "Treatise on Cold Damage" and "Essential Prescriptions of the Golden Cabinet" are concise, and many syndromes only list the core symptoms, without elaborating on the pathogenesis and differential diagnosis.

Many people think that if they memorize a prescription, they will easily confuse it with similar symptoms, and they won't know how to use it!

The "Record of Syndrome Differentiation" breaks down each disease into multiple syndrome types, and each entry clearly explains the etiology, pathogenesis, and key points for differentiation.

For example, even though it's the same type of stomach pain, it can be categorized into cold pain, heat pain, deficiency pain, qi pain, and phlegm pain, with each type's pain characteristics and accompanying symptoms clearly explained.

With a classic framework as a foundation, looking at these details will quickly help you develop the ability to differentiate between different symptoms and avoid being unsure about what to do with them.

Second, broaden the approach to prescriptions, moving from "memorizing prescriptions" to "knowing how to use them."

Typhoid fever and the Golden Cabinet mainly use classical formulas, which are concise and simple. However, after learning them, people often do not know how to modify them, or they dare not use them because of their large dosage.

The "Record of Syndrome Differentiation" contains both flexible modifications of classical prescriptions and a large number of practical contemporary prescriptions and empirical prescriptions, with a clear approach to prescription combinations.

For example, even when it comes to tonifying the kidneys, there are different formulas for tonifying yin, tonifying yang, and tonifying both Yin and Yang, with different degrees of tonification corresponding to different formulas, and the logic behind the compatibility is also explained.

Reading this book can not only expand your prescription library, but also teach you the thought process of adding or subtracting prescriptions, allowing you to break free from the limitation of simply copying the original prescription.

Third, the reasoning is straightforward and easy to understand.

Unlike the obscurity of ancient Qin and Han texts, Chen Shiduo's writing style is straightforward and clear, directly pointing out the key to dialectical analysis without any superfluous textual exposition.

For example, when discussing liver stagnation and spleen deficiency, it directly states, "When a person experiences emotional distress and dietary indiscretions, the spleen and stomach are damaged." The pathogenesis is explained clearly and is easy to understand.

With the foundation laid by the first two classic books, reading this book is almost effortless; it's like learning diagnosis from a physician with extensive practical experience, step by step.

Here are three core suggestions for reading "Record of Syndrome Differentiation".

First, do not read it through.

You don't need to read the whole book.

Start with common disease sites such as the spleen, stomach, lungs, liver, and kidneys, and focus on memorizing the core differential symptoms for each syndrome.

For example, when coughing, distinguish whether there is phlegm or not, whether the phlegm is yellow or white, whether there is dry mouth, and whether it worsens when exposed to cold. These are the key points for diagnosis.

In addition, if you encounter a problem, you can consult the table of contents at any time, similar to looking up a dictionary.

Second, learn the logic of treatment methods.

The core value of this book lies not in the number of prescriptions, but in the diagnostic approach, rather than simply memorizing prescriptions.

For example, treatment methods such as "If there is phlegm, stop treating the phlegm; if there is blood, stop treating the blood" and "Replenish fire to generate earth, replenish water to control fire" will explain the ins and outs of the specific symptoms.

Understanding these principles is more useful than memorizing ten more recipes.

Third, learn commonly used effective methods based on actual circumstances.

Many of the prescriptions in the book are meticulously formulated and have proven efficacy. For example, commonly used prescriptions for treating spleen and stomach diseases, liver stagnation, and general weakness are worth accumulating.

Most of these prescriptions are optimized based on the classic prescriptions of our predecessors, and they correspond to the knowledge of typhoid fever and the Golden Cabinet, making them easy to remember.

If you have the patience to read this far.

Since this is no longer related to the novel's plot, I'm reminding everyone again.

It's not important if it's not one of the "Four Great Classics".

Classic texts are the foundation, but clinical application requires a bridge.

Jumping directly from classical texts to clinical practice can easily lead to difficulties; the "Bian Zheng Lu" (Record of Syndrome Differentiation) serves as the best transitional bridge.

Don't just copy the prescription without considering the diagnosis.

Many people love collecting recipes.

The core of reading this book is learning "how to diagnose a patient's condition." If you only extract the prescriptions, you will miss the most valuable part and still won't be able to treat patients.

No rote memorization is required.

Traditional Chinese medicine (TCM) knowledge is vast. In the initial stage, focus on common diseases and commonly used prescriptions. Less common specialized diseases can be left for later and can be revisited later after accumulating more knowledge.
