TCM Essentials 中醫入門

Traditional Chinese Medicine (TCM) is a medical tradition with more than two thousand years of written history. Its foundational text, the Huangdi Neijing (黃帝內經, The Yellow Emperor's Inner Classic), was not written by one person. It was put together by many hands, roughly between the third and first centuries BCE, and it has been commented on, argued over, and revised ever since.

中醫是一個有兩千多年文字紀錄的醫學傳統。它的奠基經典《黃帝內經》不是一個人寫的，大約在西元前三世紀到前一世紀之間，由許多人陸續編成；之後兩千年，歷代醫家不斷為它作注、辯論、修訂。

Today it is practiced in clinics and hospitals across the Chinese-speaking world, and related traditions grew up in Korea (Korean medicine, 韓醫) and Japan (Kampo, 漢方). In Taiwan, licensed TCM physicians (中醫師) work alongside Western-trained doctors, many hospitals have a TCM department, and National Health Insurance covers TCM clinic visits.

今天，華人世界各地的診所和醫院都有中醫；韓國的韓醫、日本的漢方，也是從同一個源頭發展出來的。在台灣，有執照的中醫師和西醫並肩執業，許多醫院設有中醫部，健保也給付中醫門診。

To read TCM well, you need two lenses at once. The first is the tradition's own logic: what its concepts mean and how practitioners use them. The second is modern evidence: what clinical research has tested, what held up, and what has not been shown. Mixing the two up is the most common mistake, in both directions. Some people dismiss the whole tradition because its theory sounds strange. Others treat every traditional idea as if science had already confirmed it.

要讀懂中醫，需要同時戴兩副眼鏡。第一副看中醫自己的邏輯：這些概念是什麼意思、醫師怎麼用。第二副看現代證據：臨床研究測試過什麼、哪些站得住、哪些還沒有證明。兩者混在一起，是最常見的錯誤，而且兩個方向都有：有人因為理論聽起來陌生就全盤否定；也有人把每一個傳統說法，都當成科學已經證實。

This course keeps the two apart. The main text explains what TCM says, in its own terms. The green What research says boxes tell you, as plainly as we can, where the evidence stands.

這門課把兩者分開。正文用中醫自己的語言說明中醫怎麼講；綠色的「研究怎麼說」方塊，則盡量直白地告訴你證據目前到哪裡。

The characters tell the story. 陰 (yin) first meant the shady side of a hill; 陽 (yang) meant the sunny side. Same hill, two sides, and which side is which depends on where the sun is. Yin and yang are not two substances. They are relational labels: anything can be called more yin or more yang compared with something else.

看字就知道。「陰」原本指山的背陽面，「陽」指山的向陽面：同一座山的兩面，哪一面是陰、哪一面是陽，要看太陽在哪裡。陰陽不是兩種物質，而是相對的標籤：任何東西都可以說比另一樣東西更陰或更陽。

In TCM, health is a working balance between yang — the body's warming, moving, transforming functions — and yin — the cooling, moistening, nourishing substances that anchor them. When the balance tips, the tradition describes four basic patterns.

中醫認為，健康是陽與陰之間的動態平衡：陽是身體溫煦、推動、轉化的功能；陰是涼潤、滋養、把陽穩住的物質。平衡一旦傾斜，傳統上分成四種基本型態。

Notice that yang excess and yin deficiency can both make you feel hot — but in TCM logic the cause is opposite. One is too much heat; the other is too little cooling. The first is "cleared," the second "nourished." This is why the tradition warns against self-treating from a symptom alone.

注意：陽盛和陰虛都會讓人覺得熱，但在中醫的邏輯裡，原因剛好相反：一個是熱太多，一個是涼潤不夠。前者要「清」，後者要「補」。所以傳統上提醒，不要只憑一個症狀就自己下藥。

Qi (氣) is usually translated as "energy," and that translation causes trouble. Energy, in physics, is a quantity you can measure and store. Qi is not a substance sitting in a tank. In TCM, qi is better understood as the body doing its work: moving, warming, defending, holding things in place, and transforming food and air into the body's own substances. When a TCM physician says your qi is weak, they mean those functions are running below full strength — not that a battery is low.

氣通常被翻成「energy」，這個翻譯帶來很多麻煩。物理學的能量，是可以測量、可以儲存的量；氣不是裝在桶子裡的東西。在中醫裡，氣比較接近「身體正在做的工作」：推動、溫暖、防禦、固攝、把食物和空氣轉化成身體自己的物質。中醫師說你氣虛，意思是這些功能沒有全力運作，而不是電池沒電了。

Many teachers now leave qi untranslated, the way English keeps karma and nirvana. This course does the same.

現在很多老師乾脆不翻譯，直接寫 qi，就像英文直接用 karma、nirvana。這門課也這樣做。

Early Chinese physicians did look inside the body, but the organ names in TCM came to stand for clusters of function observed from the outside: what happens when you eat, breathe, sleep, get angry, or grow old. So when this course writes "Spleen" or "Liver" with a capital letter, read it as "the TCM Spleen system," not the organ in an anatomy textbook.

古代中國醫家確實解剖過人體，但中醫的臟腑名稱，後來代表的是從外面觀察到的一群功能：吃飯、呼吸、睡覺、生氣、變老時身體發生了什麼。所以這門課寫大寫的 Spleen、Liver，請讀成「中醫的脾系統」，而不是解剖課本裡的器官。

Each zang organ is paired with a fu (腑) organ: Liver with Gallbladder, Heart with Small Intestine, Spleen with Stomach, Lung with Large Intestine, Kidney with Bladder. The fu organs are "hollow": they receive, pass along, and empty out. A sixth fu, the Triple Burner (三焦), has no single anatomical counterpart at all; it names the pathways of water and qi through the trunk.

每一臟都和一腑配對：肝配膽、心配小腸、脾配胃、肺配大腸、腎配膀胱。六腑是「中空」的，負責受納、傳導、排出。第六腑「三焦」在解剖上根本沒有單一對應的器官，它指的是水液和氣在軀幹中運行的通道。

Because food qi is the source you control every day (Module 3), the Spleen and Stomach are called "the root of later heaven" (後天之本) — the foundation you build after birth. Much TCM advice about warm, cooked, regular meals is really advice about protecting the Spleen. The tradition says the Spleen likes dryness and warmth and dislikes dampness and cold; that is why a large iced drink on an empty stomach is a classic thing TCM tells you to avoid.

因為水穀之氣是你每天能掌握的來源（第三單元），脾胃被稱為「後天之本」，也就是出生之後要自己打下的根基。中醫許多「吃溫的、煮熟的、定時吃」的建議，其實都是在保護脾。傳統說脾喜燥惡濕、喜溫惡寒，所以空腹灌一大杯冰飲，是中醫最常勸你避免的事之一。

The five xing (五行) are often called the "Five Elements," but 行 means to move or to act, so many scholars prefer "Five Phases." They are not chemical elements. They are five categories for sorting how things behave: Wood grows and spreads, Fire rises and flares, Earth holds and nourishes, Metal gathers and contracts, Water sinks and stores.

五行常被譯成「Five Elements」，但「行」的意思是運行、作用，所以許多學者比較喜歡譯成「Five Phases」。它們不是化學元素，而是五種歸類事物行為的類別：木生長舒展，火上炎，土承載化育，金收斂，水下行閉藏。

A classic strategy is called 培土生金, "bank up Earth to generate Metal." Someone with weak digestion (Earth, the Spleen) who also catches colds easily (Metal, the Lung) may be treated mainly by strengthening digestion, on the reasoning that the mother phase feeds the child. This is how the five phases are used in practice: as a way of reasoning about connections, so that a physician looks beyond the organ where the symptom appears.

有一個經典治法叫「培土生金」。一個人消化弱（土，脾），又容易感冒（金，肺），醫師可能主要從強化消化下手，理由是母行能滋養子行。這就是五行在臨床上的用法：一種推想臟腑關聯的方法，讓醫師不只盯著症狀出現的那個器官。

TCM pays attention not only to what is wrong today, but to the kind of body you have: the direction you tend to drift when you are tired, stressed, or eating badly. This is your constitution (體質, tizhi). Two people can catch the same cold and react quite differently, and TCM would say part of the reason is constitution.

中醫不只看你今天哪裡不舒服，也看你是什麼樣的身體：當你累了、壓力大、飲食不規律時，身體習慣往哪個方向偏。這就是「體質」。兩個人得了同樣的感冒，反應卻很不一樣，中醫會說，部分原因就在體質。

The best-known modern system was developed by Professor Wang Qi (王琦) of the Beijing University of Chinese Medicine. It describes nine constitutions and became a standard of the China Association of Chinese Medicine in 2009. Researchers assess it with a 60-item questionnaire. Most people are not one pure type; they have a main tendency and often a second one.

最有名的現代分類，是北京中醫藥大學王琦教授提出的九種體質，2009 年成為中華中醫藥學會的標準。研究上用一份 60 題的問卷來判定。大部分人不是單純一型，而是有一個主要傾向，常常還帶著第二個。

Constitution is described as a starting point, not a destiny. In the tradition it shifts slowly with age, diet, sleep, climate, and emotional life — which is the whole reason TCM gives so much daily-life advice.

體質被看成起點，不是命運。傳統認為它會隨著年齡、飲食、睡眠、氣候和情緒生活慢慢改變，這也正是中醫給這麼多生活建議的原因。

A classical phrase says 藥食同源: medicine and food come from the same source. TCM draws no sharp line between the kitchen and the pharmacy; ginger, scallions, Chinese yam, and red dates all appear in classical formulas. The aim of eating well, in TCM terms, is to choose foods whose properties balance your body, the season, and the climate you live in.

古話說「藥食同源」。中醫不在廚房和藥房之間畫一條硬線：薑、蔥、山藥、紅棗都出現在經典方劑裡。照中醫的說法，吃得好，就是選擇性質能平衡你的身體、季節和居住氣候的食物。

Foods are sorted on two scales. Nature (性) runs cold – cool – neutral – warm – hot and describes the food's effect on the body, not its temperature on the plate: watermelon is cold even at room temperature, and ginger is warm even in an iced drink. Flavor (味) has five values — sour, bitter, sweet, pungent, salty — each said to act in a particular way.

食物用兩把尺來分。性從寒、涼、平、溫到熱，描述食物吃進去對身體的作用，不是盤子上的溫度：西瓜放在室溫下仍是寒的，薑加進冰飲裡仍是溫的。味有五種：酸、苦、甘、辛、鹹，傳統上各有不同的作用。

The Neijing devotes a whole chapter (Suwen, Chapter 2) to living in step with the seasons. The principle is to go in the same direction as the season's movement: grow in spring, flourish in summer, gather in autumn, store in winter.

《內經》用一整篇（〈素問・四氣調神大論〉）講順應四季。原則是跟著季節的方向走：春生、夏長、秋收、冬藏。

You will often see a "TCM body clock" that gives each of the twelve main channels a two-hour peak: Lung from 3 to 5 a.m., Large Intestine 5 to 7, Stomach 7 to 9, and so on around the day. Its roots are old — the Neijing already describes qi flowing through the channels in a fixed order, but gives no clock times. The two-hour clock appears in later acupuncture texts — for example Dou Hanqing's Zhenjing Zhinan (針經指南, Yuan dynasty, 1295) — and is often taught under the name 子午流注, a term that also covers older methods for choosing points by day and hour.

常會看到一張「中醫人體時鐘」，把十二經脈各配一個兩小時的旺時：凌晨三到五點肺經、五到七點大腸經、七到九點胃經，繞一整天。它的根源很早：《內經》已經講到氣按照固定的順序流經各條經脈，但沒有標出時刻。兩小時一格的時鐘，出現在後來的針灸書裡，例如元代竇漢卿的《針經指南》（1295 年）；今天常以「子午流注」之名傳授，不過這個名稱也包括更早一套依日期、時辰選穴的方法。

Meridians, or channels (經絡, jingluo), are the pathways along which TCM says qi and blood circulate, linking the surface of the body to the organs inside. There are twelve principal channels, each named for an organ, plus eight "extraordinary vessels" — the best known are the Governing Vessel (督脈) up the spine and the Conception Vessel (任脈) down the front midline.

經絡是中醫認為氣血運行的通道，把體表和體內的臟腑連在一起。主要有十二正經，各以一個臟腑命名；另有奇經八脈，最有名的是沿著背脊上行的督脈，和沿著身體前正中線的任脈。

Along the channels lie the acupuncture points (穴位). In 2008 the World Health Organization published standard locations for 361 of them, using codes like LI4 (Large Intestine 4) and ST36 (Stomach 36), so that practitioners and researchers around the world mean the same spot.

經絡上分布著穴位。世界衛生組織在 2008 年公布了 361 個穴位的標準定位，用 LI4（大腸經第 4 穴）、ST36（胃經第 36 穴）這類代碼，讓全世界的醫師和研究者說的是同一個位置。

Acupressure — firm pressure with a thumb or fingertip — is the self-care version of acupuncture. Press straight into the point for 30 to 60 seconds, or rub in small circles for a minute or two, firmly enough to feel a dull ache but not sharp pain. Do both sides. The traditional unit of measurement is the cun (寸), based on your own body: the width of four fingers held together is about 3 cun.

指壓是針灸的自我保健版：用拇指或指腹穩穩地往穴位按 30 到 60 秒，或小圈揉一兩分鐘，力道以感到痠脹、不刺痛為準，左右兩側都按。傳統的量法用「寸」，以自己的身體為準：四指併攏的寬度大約是 3 寸。

The Chinese word 針灸 (zhenjiu) joins two therapies: 針, needling, and 灸, moxibustion — warming a point with burning mugwort (艾草). Modern acupuncture needles are nothing like injection needles. They are solid, flexible, and very thin (roughly 0.16 to 0.30 mm), sterile, and used once. Most people feel a brief prick, then a dull, heavy, or spreading ache called de qi (得氣).

「針灸」包含兩種療法：「針」是扎針，「灸」是用點燃的艾草溫熱穴位。現代針灸針和打針的針完全不同：實心、有彈性、非常細（大約 0.16 到 0.30 公釐），無菌、用一次就丟。大部分人只感到短暫的刺一下，接著是痠、脹、重或擴散的感覺，叫做「得氣」。

Chinese herbal medicine is TCM's deepest clinical tool, with a written tradition running from the Shennong Bencao Jing (神農本草經, Eastern Han dynasty, 365 substances) to Li Shizhen's great Bencao Gangmu (本草綱目), finished in 1578 and printed in the 1590s. Most substances are plants; some are minerals or animal products.

中藥是中醫最深的臨床工具。文字傳統從東漢的《神農本草經》（收藥 365 種），一直到李時珍的《本草綱目》（1578 年完成，1590 年代刊行）。藥材大多是植物，也有礦物和動物來源。

Unlike much Western herbalism, TCM rarely uses one herb alone. It uses formulas (方劑) of several herbs with assigned roles — the "sovereign, minister, assistant, and envoy" (君臣佐使). The sovereign targets the main problem; the minister supports it; the assistant handles side issues or tempers harshness; the envoy guides and harmonizes the whole.

和許多西方草藥學不同，中醫很少只用一味藥，而是用好幾味藥組成方劑，各有角色，叫做「君臣佐使」：君藥針對主要問題，臣藥輔助君藥，佐藥處理次要問題或緩和藥性，使藥引導並調和全方。

These are classified as both food and medicine and are reasonable for everyday cooking in normal amounts: fresh ginger (生薑), red dates (紅棗), goji berries (枸杞), dried tangerine peel (陳皮), and Chinese yam (山藥). Anything beyond the kitchen — capsules, concentrated extracts, or a formula — is a conversation for a licensed practitioner.

這幾種屬於藥食兩用，日常以一般份量入菜是合理的：生薑、紅棗、枸杞、陳皮、山藥。超出廚房範圍的，例如膠囊、濃縮萃取物或方劑，就該找有執照的醫師談。

Self-care from this course is for mild, short-lived things: a tired week, a heavy meal, a stiff neck, seasonal adjustments. Anything more benefits from a professional — Western, TCM, or both.

這門課的自我保健，適用於輕微、短暫的狀況：累了一週、吃得太撐、脖子僵硬、季節轉換的調整。超過這些，就該找專業人員：西醫、中醫，或兩者都看。

In Taiwan, call 119 for an ambulance. Do not delay any of these with herbs, acupressure, or waiting to see.

在台灣，叫救護車請打 119。以下情況都不要用中藥、按穴位或「再觀察看看」來拖延。

People commonly seek TCM for chronic pain, headaches, digestive complaints without a structural cause, sleep and stress, menstrual pain and menopausal symptoms, allergic rhinitis, and support during recovery from illness or cancer treatment. The strength of evidence differs across this list (Module 10), so it is reasonable to agree on a trial period and a clear sign of improvement before you start.

大家常為了這些找中醫：慢性疼痛、頭痛、沒有器質性原因的腸胃不適、睡眠與壓力、經痛與更年期症狀、過敏性鼻炎，以及病後或癌症治療期間的調養。這些項目的證據強弱不一（見第十單元），所以開始之前，和醫師約定一段嘗試期、以及怎樣才算改善，是合理的做法。
