The names outsiders gave it
For decades in English, the practice was not called gua sha. It was called coining, or coin rubbing, and it appeared under those names in clinical and social-work contexts long before the term that is now standard.
Those names are exonyms — names given from outside — and they follow a pattern worth spelling out. Every insider name for this practice describes what it is aimed at. Every outsider name describes what it is done with.
What the insider names point at
Look at the set together.
刮痧 (guā shā) names the action and its object: scrape the sha. The target is in the name.
Cạo gió names the action and its object: scrape the wind. Again the target.
Kerokan names the action alone, from kerok, to scrape — with the target supplied by the complaint it treats, masuk angin, entering wind. The target is one step away rather than absent.
In every case the naming is oriented toward why. The name presupposes a framework in which sha or wind is a thing that exists and can be got at, and it takes that framework for granted, because everyone using the word shares it. Nobody needs the tool mentioned; you use whatever is to hand.
What the outsider names point at
Now the English ones. Coining. Coin rubbing. Both name the implement.
This is exactly what you would expect from a name coined by someone who is describing what they observed rather than what was intended. A clinician looking at a child’s back does not have access to the framework. They have access to a pattern of marks and, if they ask, an account involving a coin. So the practice gets named for its most visible physical component, and the name carries no information about what it was for.
The same logic produces the other outsider terms that circulate — descriptions built from the tool or the appearance rather than from the purpose, and phrasings whose evident function is identification. Terms along the lines of “spooning” appear where the implement observed was a spoon, which makes the point neatly: an exonym tracks whatever object happened to be in the room.
Two consequences follow, and both are visible in the older English-language material.
The exonyms fragment the practice. Named by implement, gua sha, cạo gió and kerokan look like three or four different practices, because coining, spooning and scraping sound unrelated. Named by target, they are visibly members of one family. The English vocabulary made the family resemblance harder to see at exactly the moment when someone noticing it would have been most useful.
They carry no framework, so they invite one. A name that says nothing about purpose leaves the purpose to be supplied by the observer, which is how a household remedy came to be described in terms borrowed from injury rather than from treatment.
There is a third effect, subtler and worth adding. An implement-based name makes the practice sound improvised. “Coining” describes somebody making do with money, which reads as a substitute for proper treatment — and that reading is almost exactly wrong. The coin was not a substitute for a purpose-made tool that families could not afford; it was the ordinary and preferred implement, and the purpose-made tool is the later arrival. The exonym encoded a misunderstanding of the practice’s economics into its English name, and the misunderstanding outlasted the name.
WHAT'S ACTUALLY KNOWN — the exonyms
· "Coining" and "coin rubbing" were the common
English terms → documented
· They name the implement, not the purpose
→ documented
· Insider names across the region name the target
→ documented
· Implement-based naming fragments the practice
family in English → plausible inference
· Which exonym came first
→ not established
· Whether any exonym was ever used by
practitioners of the practice → not establishedWhy “gua sha” displaced them
The current dominance of the Mandarin term in English is recent and has an identifiable set of causes.
It arrived with the professional tradition. Practitioners of Chinese medicine working in the West used the Chinese term, and as that tradition became the frame through which the practice was described, its vocabulary came with it.
It was the term a market needed. A retail category wants one name, and it wants a name that sounds like a practice rather than a description of an object. “Coining” would have been a poor label for a skincare product; it names a coin, which nobody was selling.
Mandarin is the region’s most exported vocabulary. Where several cultures have a practice and one of them has far greater global linguistic reach, that one’s term tends to become the international name. This is an ordinary asymmetry of language contact, not a judgement about origins — and it is worth remembering that it operates independently of who actually had the practice first.
The displacement was on the whole an improvement: an insider term with real content replaced an outsider term with none. But it flattened something on the way, which is that the practices with their own names now all get called by the Mandarin one. An Indonesian or Vietnamese practice described in English as gua sha has been renamed twice, and the second renaming is less visible than the first because it looks like a correction.
Why it matters
Two reasons, one historiographic and one practical.
The exonyms are where the early English record is. The Western clinical literature on misread marks is largely filed under coining, coin rubbing, cạo gió and related terms rather than under gua sha. Anyone searching the current term for the practice’s early Western history will conclude there isn’t any, when in fact there is a substantial body of it under names that have fallen out of use. This is a large part of why the practice appears in popular writing to have sprung into Western awareness in the 2010s.
Naming by implement is what produced the current confusion. English’s habit of naming this practice after its object did not stop with coining. It continues in “a gua sha,” meaning the stone — the same instinct, applied to an insider term, converting a phrase about an illness into a word for a thing you can buy. The exonyms were the first version of that move, and they show it was never really about the Chinese.
