The regional relatives

Gua sha is not unique, and it isn’t even unusual. Practices that consist of dragging a smooth-edged object firmly across oiled skin until reddish marks appear exist across a broad stretch of Asia, under different names, with different explanatory frameworks and almost identical execution.

The English-language conversation rarely mentions this, which is a shame, because the family resemblance is the most interesting fact about the practice — and it complicates the confident origin stories considerably.

Cạo gió

In Vietnam the practice is cạo gió, which translates roughly as “scraping wind.”

Cạo is to scrape. Gió is wind. The framing is explicit: illness of a certain type is understood as wind having got into the body, and the scraping brings it out. It’s performed on the back, the neck, the shoulders and sometimes the chest and arms, typically with a coin — a metal coin drawn along oiled skin, often with medicated balm as the lubricant — until the characteristic red lines appear.

Anyone who has seen gua sha performed would recognise it immediately. Same posture, same tool, same strokes, same marks, same set of complaints it’s used for: the onset of a cold, headache, fever, nausea, general malaise.

The explanatory concept differs in emphasis. Wind as a pathogenic influence exists in Chinese medical vocabulary too, so this isn’t a different theory so much as a different accent within a shared regional framework.

Kerokan

In Java the practice is kerokan, from kerok, to scrape.

Again: a coin, usually a large one, drawn along oiled skin — traditionally with coconut oil or a warming liniment — producing red lines down the back in a distinctive pattern, often laid out in parallel strokes along either side of the spine and out along the ribs. It’s used for masuk angin, literally “entering wind,” a widely recognised Indonesian complaint covering roughly the same territory: chill, bloating, aching, feeling off.

Kerokan is extremely common and entirely ordinary in Indonesia. It’s not a niche traditional revival; it’s what a great many people do when they feel like they’re coming down with something, and the marks are visible in daily life without attracting comment.

Note the conceptual echo. Masuk angin and cạo gió both centre on wind entering the body, and both practices bring it out through the skin.

Others

The family extends further. Cambodian and Lao practices of the same kind exist under their own names. Coin rubbing in various forms is documented across mainland Southeast Asia and among diaspora communities from all these regions.

Cupping is the obvious cousin from a different direction — a different mechanism, glass or bamboo and suction rather than an edge and shear, but the same underlying logic of drawing something to the surface and the same expectation of visible marks as evidence. Its geographical range is much wider, taking in the Middle East and, historically, Europe.

And the wider comparison is worth making, because it resists exoticising the Asian practices: European folk medicine had its own repertoire of counter-irritation — cupping, blistering, mustard plasters, cauteries — resting on very similar reasoning about drawing morbid matter out through the skin. Bringing something bad to the surface is not an East Asian idea. It’s a widespread human one, and it appears wherever the skin is understood as a boundary that things can be moved across.

What’s actually known

WHAT'S ACTUALLY KNOWN — the family

  · Cạo gió (Vietnam) and kerokan (Indonesia) are
    closely comparable practices with distinct names
    and local frameworks
                              → documented

  · The coin is the common tool across all of them
                              → documented

  · All are used for a similar cluster of acute,
    non-specific complaints
                              → documented

  · Wind as a pathogenic concept recurs across the
    regional frameworks
                              → documented

  · One of these is the original and the others
    derive from it
                              → NOT KNOWN. Commonly assumed
                                for gua sha; the assumption
                                is not supported.

  · They arose independently
                              → also not known; plausible
                                inference at best

  · Counter-irritation practices exist in many
    unrelated cultures
                              → documented

The origin question, and why it doesn’t resolve

The obvious question is which came first, and the honest answer is that nobody can say.

The reasons are the same ones that make gua sha’s own history thin, compounded across several cultures. Household practices don’t leave records. Where records exist they’re late. The region has millennia of trade, migration, conquest and cultural exchange, so any of these could have spread in any direction at almost any time. And the technique is simple enough — a smooth edge, some oil, firm pressure — that independent invention is entirely plausible, possibly multiple times.

The default assumption in English-language writing is that gua sha is the original and the others are regional variants, and it’s worth noticing that this assumption is doing no evidentiary work. It’s there because gua sha is the version English speakers heard of first, and because China is the largest and most documented of the cultures involved. Neither is an argument about chronology.

Widely assumed, not established is the correct label, and it’s an unsatisfying answer that happens to be the accurate one.

Why the relatives matter

Three reasons this is worth knowing beyond trivia.

It defuses the antiquity claim. When a practice appears in near-identical form across many cultures with different names and different theories, “it dates to a specific dynasty” becomes a much harder claim to make. You’d be dating one branch of something that might be older, or younger, or plural.

It matters clinically. Western clinicians who encounter these marks are as likely to be seeing kerokan or cạo gió as gua sha, depending on the community, and the literature that developed on this in Western medicine spans all of them. That story is part of the transmission.

It reframes the appropriation question. Discussions of gua sha’s commercialisation are usually framed as a bilateral matter between China and the West. The practice’s actual distribution across several cultures — with diaspora communities in Western countries practising all of the variants — makes the “whose is it” question genuinely more complicated than the usual framing allows, and that complication is worth sitting with rather than resolving.
