Traditional Chinese Medicine
Yin and yang ★★★
In Chinese philosophy, concepts used to describe how apparently opposite or contrary forces are actually complementary, interconnected and interdependent in the natural world, and how they give rise to each other as they interrelate. Many tangible dualities — light and dark, fire and water, male and female — are thought of as physical manifestations of this duality.
The document is careful about one word, and the quiz may be too: yin and yang are complementary rather than opposing forces, interacting to form a dynamic system in which the whole is greater than the assembled parts. Everything has both yin and yang aspects — as the document puts it, shadow cannot exist without light — and either aspect may manifest more strongly depending on the criterion of observation.
| Where it appears | Detail |
|---|---|
| Classical Chinese science and philosophy | The duality lies at the origins of many branches |
| Traditional Chinese medicine | A primary guideline |
| Martial arts and exercise | A central principle of baguazhang, taijiquan (t'ai chi) and qigong |
| The I Ching | Present throughout |
One philosophical distinction the document draws explicitly: in Taoist metaphysics, distinctions between good and bad — and other dichotomous moral judgements — are perceptual, not real, so the duality is an indivisible whole. In Confucian ethics, most notably in the philosophy of Dong Zhongshu (c. 2nd century BC), a moral dimension is attached to yin and yang.
The distinction is the whole idea, and it is easy to lose in translation.
Opposites exclude each other — a thing is either hot or cold. Complementary forces require each other: there is no shadow without light, and nothing is purely one or the other. That is why the document says everything has both aspects, and why which aspect dominates depends on what you are measuring.
That has a direct medical consequence. If health is a dynamic balance between complementary forces rather than the absence of a bad one, then treatment means restoring balance, not eliminating an enemy — which is a different programme from finding a pathogen and killing it. Holding both models is exactly what this subject is asking you to do.
- Are yin and yang opposing or complementary? → Complementary — interconnected and interdependent, giving rise to each other
- Does anything have only one aspect? → No — everything has both; which dominates depends on the criterion of observation
- What is yin-yang's role in TCM? → A primary guideline
- How do Taoist and Confucian views differ? → Taoism treats moral distinctions as perceptual, not real; Confucianism (Dong Zhongshu) attaches a moral dimension
Qi-gong ★★
| Fact | Detail |
|---|---|
| Age | The history of qi-gong dates back about 5000 years |
| The name | Only adopted widely in 1953, when Liu Gui-zheng published a paper entitled Practice On Qigong Therapy |
| Origin | Thought to have originated as a form of “remedy dancing” created for healing and health preservation |
| Development | Divided into four major periods |
| Before 206 BC | Marked by the Yi Jing (Book of Changes, c. 1122 BC) — the first book to introduce qi (vital energy) |
Before 1953 the practice went by many names, and the list is revealing about what it was understood to be: xing-qi (promoting the circulation of qi), fu-qi (taking qi), dao-yin (guiding the energy flow), tui-na (exhaling and inhaling), zuo-chan (sitting in meditation), yang-shen (nourishing the spirit) and jing-zuo (sitting still).
That gap is worth noticing, because it explains something about how traditional medicine is discussed.
The practice is ancient; the category is modern. Before 1953 there was no single thing called qi-gong — there were seven or more differently-named exercises, some about breathing, some about movement, some about sitting still. Naming them together in a 1953 paper created the unified subject.
The document also gives the practical origin: the ancients, through long struggle with nature, gradually realised that body movements, exclamations and various ways of breathing could help readjust certain body functions. That is an empirical observation, arrived at without theory — much as Jenner's milkmaids were, in Unit 7.
- How old is qi-gong, and when was it named? → About 5000 years old; the name was adopted in 1953
- Who published the naming paper? → Liu Gui-zheng, 'Practice On Qigong Therapy'
- What is it thought to have originated as? → 'Remedy dancing' for healing and health preservation
- Which book first introduced qi? → The Yi Jing (Book of Changes), c. 1122 BC
- How many major periods of development? → Four
Acupuncture ★★★
The document opens by saying there are two very different ways of looking at acupuncture: from the traditional Chinese perspective and from the modern international perspective. Both are worth being able to state.
The dominant function of acupuncture is to regulate the circulation of qi (vital energy) and blood. Roughly 2000 years ago the pre-eminent acupuncture text, the Huangdi Neijing (Yellow Emperor's Classic of Internal Medicine), described acupuncture as a means of letting out excess qi or blood by making holes in the body along certain pathways called jingluo (meridians).
The classical model was specific about what was released where: for some meridians it was advised to needle so as to let out the blood but not the qi; for others, the qi but not the blood.
It also had a model of how disease progressed. Many diseases were thought to enter the body through the skin, then penetrate inward through muscle, then internal organs, and — if not cured in time — to the marrow of the bone. By inserting a needle to the appropriate depth, corresponding to the degree of penetration, the disease could be let out.
The document offers an explanation that is both generous and precise, and it is the most interesting sentence in the whole strand.
Prior to microscopes, and before autopsies revealed the intricate structures within the body, doctors and scholars projected the internal workings of the body from what they could actually experience — which was the world outside the body.
So rivers and channels become meridians; weather entering a house becomes disease entering through the skin; blockage and flow become the model of illness. The theory is not arbitrary — it is a careful analogy from the only evidence available.
That connects straight back to Unit 7. Leeuwenhoek's microscope is what ended the era of reasoning by analogy about the inside of the body. Before the instrument, projection from the outside world was the only method anyone had — in China and in Europe alike.
- What are the two perspectives on acupuncture? → The traditional Chinese and the modern international
- What is its dominant traditional function? → To regulate the circulation of qi and blood
- Name the pre-eminent text, and its age. → Huangdi Neijing (Yellow Emperor's Classic of Internal Medicine), about 2000 years old
- What are jingluo? → The meridians — pathways along which holes are made
- How was disease thought to progress? → Skin → muscle → internal organs → marrow of the bone
- Why does the theory use external-world imagery? → Before microscopes and autopsy, the inside of the body was projected from the world outside it
What Quiz 2 actually asks ★★★
Quiz 2 is the best available guide to how this strand is examined. It has two sections: True/False statements, and MCQs with options a–f including all of the above and none of the above.
This option changes the arithmetic of guessing, and it is worth a moment because no other subject this semester uses it.
If you can confirm two options are true, 'all of the above' becomes very likely — examiners rarely construct a list where exactly two of four are correct and the fifth option is a catch-all.
If you can eliminate even one option confidently, 'all of the above' is dead — and so is any option depending on it.
So work by elimination, not by hunting for the single best answer. And always read to option f: with 'none of the above' present, the answer may be that every listed item is wrong.
- What two question formats does Quiz 2 use? → True/False, and MCQ with options a–f
- What is special about the option list? → It includes 'all of the above' and 'none of the above'
- Which principle is Sun Simiao known for? → Preventing illness before it occurs
- What does the quiz mixing genetics with TCM tell you? → Revise the strands together — one quiz covers several
