What does the title Yi Xue Zhong Zhong Can Xi Lu mean?

The title translates roughly as 'Records of Sincerely Using Chinese [Medicine] While Referencing Western [Medicine]' (医学衷中参西录). 'Zhong' refers to Chinese medicine, 'Xi' refers to Western medicine. The title reflects the author's approach: treating primarily with TCM while incorporating Western medical knowledge where it enhances understanding and treatment.

Who was Zhang Xichun and why is he important?

Zhang Xichun (1860-1933) was one of the most important Chinese physicians of the early 20th century. He is considered a founder of the 'Integrative Medicine' movement in China. Uniquely trained in both TCM and Western medicine, he created formulas that combined Chinese herbs with Western pharmaceutical substances — a revolutionary approach at the time. His clinical records are valued for their detailed case documentation.

Yi Xue Zhong Zhong Can Xi Lu (医学衷中参西录): Integrating Chinese and Western Medicine by Zhang Xichun

What Is Yi Xue Zhong Zhong Can Xi Lu?

Yi Xue Zhong Zhong Can Xi Lu (医学衷中参西录), published in stages between 1909 and 1933, is one of the most innovative texts in the history of Chinese medicine. Written by Zhang Xichun (张锡纯, 1860–1933), this pioneering work attempted to integrate Traditional Chinese Medicine with Western medical science — making it one of the earliest and most influential texts in the “Zhong Xi Yi” (Chinese-Western integrative medicine) movement.

The title captures the philosophy: “Sincerely using Chinese [medicine] while referencing Western [medicine]” — treating primarily with TCM while incorporating Western knowledge where it improves understanding and outcomes.

The Author: Zhang Xichun

A Physician Between Two Worlds

Born in 1860 in Hebei Province during the late Qing Dynasty
Trained classically in TCM from childhood by his father
Self-taught in Western medicine through translations of Western medical texts that became available in China in the late 19th century
Became one of the first Chinese physicians to seriously study and practice both systems

His Philosophy

Zhang Xichun believed:

TCM’s theoretical framework was profound and invaluable
Western medicine’s anatomical and physiological knowledge could enhance TCM practice
The two systems were complementary, not contradictory
A physician should use whatever works best for the patient

Key Innovations

1. Formulas Combining Chinese Herbs and Western Medicines

Zhang Xichun created formulas that literally combined TCM herbs with Western pharmaceutical substances — revolutionary for his time:

Formula Name	Chinese Herbs	Western Component	Purpose
Shi Jue Ming San	Shi Jue Ming (Abalone Shell)	Calcium carbonate	Hyperacidity, gastric pain

Shi Gao + Aspirin | Shi Gao (Gypsum) | Aspirin | High fever from external wind-heat |
Gan Cao + Bromide | Gan Cao (Licorice) | Potassium bromide | Seizures, convulsions |

The Shi Gao + Aspirin combination for high fever is perhaps his most famous innovation. Zhang observed that aspirin effectively reduced fever but was “cold and dispersing” — which could weaken the patient. Adding Shi Gao (Gypsum, which clears intense heat in TCM) enhanced the fever-reducing effect while the combination was more balanced than aspirin alone.

2. Anatomical and Physiological Integration

Zhang Xichun was one of the first TCM physicians to:

Reference Western anatomical knowledge when discussing organ function
Incorporate blood circulation understanding from Western physiology
Use stethoscope and thermometer readings alongside traditional pulse and tongue diagnosis
Explain TCM concepts using Western physiological language where appropriate

3. Detailed Case Records

The text contains extensive case records (医案) that are notable for their:

Detailed symptom documentation
Clear reasoning for formula selection
Honest reporting of both successes and failures
Follow-up notes on patient outcomes

These case records remain valuable today as models of clinical documentation.

Notable Formulas from the Text

Zhen Gan Xi Feng Tang (镇肝熄风汤)

Subdue the Liver and Extinguish Wind Decoction

One of Zhang Xichun’s most famous formulas, still widely used today:

Herb	Chinese	Role
Niu Xi	牛膝	Chief — directs Blood downward, anchors Yang
Dai Zhe Shi	代赭石	Chief — descends Qi, anchors Liver Yang
Long Gu	龙骨	Deputy — calms the Liver, anchors Yang
Mu Li	牡蛎	Deputy — anchors Yang, softens nodules
Bai Shao	白芍	Deputy — nourishes Liver Blood, softens Liver
Xuan Shen	玄参	Assistant — nourishes Yin, clears heat
Tian Men Dong	天门冬	Assistant — nourishes Yin

Chuan Lian Zi | 川楝子 | Assistant — moves Liver Qi, relieves pain |
Mai Ya | 麦芽 | Assistant — moves Liver Qi harmoniously |
Yin Chen Hao | 茵陈 | Assistant — clears Liver heat |
Gan Cao | 甘草 | Envoy — harmonizes

Indications: Stroke, hypertension with severe Liver Yang rising — headache, vertigo, facial flushing, hemiplegia.

Jian Ling Tang (建瓴汤)

For milder Liver Yang rising:

Hypertension with dizziness, tinnitus
Insomnia with restlessness
Prevents progression to stroke

Yu Ye Tang (玉液汤)

For diabetes (Xiao Ke) with Qi and Yin deficiency:

Contains Huang Qi, Shan Yao, Sheng Di Huang, and others
Addresses the “wasting and thirsting” pattern with modern understanding of blood sugar

Theoretical Contributions

Redefining TCM Concepts with Western Knowledge

Zhang Xichun proposed several reinterpretations:

“Qi” — suggested parallels with Western concepts of nerve force and vital energy
“Blood” — acknowledged the Western understanding of blood composition while maintaining TCM’s functional perspective
“Meridians” — suggested possible connections to the nervous and vascular systems
“Kidney” — noted the correspondence between TCM Kidney function and adrenal/endocrine activity

The Concept of “Zhong Xi Hui Tong” (中西汇通)

Zhang Xichun advocated for “convergence and understanding” between Chinese and Western medicine:

Not replacing TCM with Western medicine — preserving TCM’s unique theoretical framework
Not rejecting Western medicine — incorporating useful knowledge where it fills gaps
Practical synthesis — using whatever approach best serves the patient
Respectful dialogue — understanding both systems deeply before integration

Legacy and Modern Relevance

Influence on Modern TCM

Zhang Xichun is considered a founding figure of integrative Chinese-Western medicine
His approach directly influenced the development of modern Chinese hospitals where TCM and Western medicine are practiced together
Many of his formulas (especially Zhen Gan Xi Feng Tang) are in standard TCM textbooks
His case records are studied as models of clinical reasoning

Relevance Today

China’s modern medical system explicitly practices “Zhong Xi Yi Jie He” (integrative medicine) — directly descended from Zhang Xichun’s vision
Many Chinese hospitals have both TCM and Western departments working together
His approach of “using Chinese medicine as the foundation while referencing Western science” remains the official stance of TCM education in China
The global integrative medicine movement echoes his century-old insights
