Shiro Roga in the Sushruta Samhita: the Eleven Diseases of the Head - Ardhavabhedaka, Suryavarta, Anantavata and Shankhaka (Uttara Tantra 25-26)

📖 25 min read · Part of our classical-text series on the Sushruta Samhita

A physician with no imaging, no blood test and no instrument beyond his own hands sits opposite someone whose head hurts. Every headache looks identical from the outside. There is nothing to see, nothing to press, nothing to measure. And yet he must separate them, because what he does next depends entirely on which one this is.

So he asks about time. When did it start — at what hour? Worse as the day goes on, or better? Worse at night? Does it come back, and after how many days? And then he asks about the hand: does it help if I press here? If we bind the head? Something warm on it — or something cold?

That is the twenty-fifth chapter of the Sushruta Samhita’s Uttara Tantra, and it is one of the most quietly modern chapters in the classical corpus — not because it got the causes right, but because it got the method right. It separates eleven distinct Shiro Rogas almost entirely on the evidence of a clock and a palm.

One promise before we begin, as always in this series: everything below is textual scholarship. The verses name conditions with the confidence of their own era; we quote and explain them as history. Nothing here is medical advice, and nothing we sell is a treatment for anything at all.

Where Today’s Verses Sit: the Nose Behind Us, the Head Ahead

Our reading picks up mid-sentence. The Uttara Tantra — the Sushruta Samhita’s sixth and final section, the “latter teaching” — has been working its way up the body’s openings: the eye across a long run of chapters, then the ear, then the nose. Today’s pages open on the closing verses of Chapter XXIV, the Pratishyaya Pratishedha, which our reading of the five catarrhs covered in full. Then the manuscript closes that chapter with its formula and opens a new one. The nose is finished. The head itself begins.

The architecture is worth a pause, because the Uttara Tantra does something the rest of the compendium does not. Everywhere else, Sushruta separates nidana (diagnosis) from chikitsa (therapeutics) into different books: the Nidana Sthana defines and distinguishes; the Chikitsa Sthana prescribes. Here the two are welded back together in pairs — a Vijnaniya chapter (“that which is to be known”) describes, and the Pratishedha chapter after it answers. So today we get both halves in sequence.

The Source: Sushruta Samhita, Uttara Tantra, Shiro-roga Vijnaniya

The Uttara Tantra pairs its chapters: one to describe a disease, the next to answer it.

The Sushruta Samhita is arranged in six sthanas, and the Uttara Tantra is the last and by some distance the strangest — sixty-six chapters gathering everything the first five books did not cover, including the whole of Shalakya Tantra, the branch dealing with what lies above the collarbone. That is why the eye, the ear, the nose and now the head all live here together. Many scholars hold it to be a later addition to the original compendium; whatever its date, it is the oldest surviving systematic account of head and sense-organ disease in the Indian tradition.

Chapter XXV opens with the standard formula — “Now we shall discourse on the chapter which deals with the symptoms of diseases peculiar to the region of the head” — and names itself the Shiro-roga Vijnaniya. Shiras is the head; roga is disease; vijnaniya is that which is to be discerned, told apart, known. The title is a promise about method.

Our translation throughout is Kaviraj Kunja Lal Bhishagratna’s English Sushruta (Calcutta, 1907–1916), still the most widely cited complete English rendering. Where his 1911 glosses belong to his era rather than to the text, we set them aside and stay with the Sanskrit. He also preserves the commentators Dallana, Gayadasa and Madhava.

The Eleven Shiro Rogas: Sushruta’s Census of the Aching Head (XXV.2)

Like almost every classical chapter, this one begins by counting. Verse 2 lays out the census in a single breath:

Read the list slowly and you will notice it is really two lists welded into one, and that the join is visible.

The first seven are named by cause, in the standard grammar of Ayurvedic pathology: by dosha (Vataja, Pittaja, Kaphaja, Tridoshaja), by tissue-depletion (Kshayaja), by blood (Raktaja), by krimi (Krimija). The last four are named by something else entirely. Suryavarta is named for the sun; Ardhavabhedaka for a geometry, half the head; Shankhaka for a place, the shankha or temple; Anantavata for Ananta, the endless serpent coiled at the base of the world. These are not aetiologies. They are field observations so distinctive, so unmistakable to anyone who had seen them once, that they earned proper names and kept them.

And the chapter is quietly honest about this. Having named the last four separately, it then tells us that three of them — Suryavarta, Anantavata and Ardhavabhedaka — are all due to “the concerted action of the three Doshas,” which is to say: by the first list’s logic they would all be Tridoshaja and indistinguishable. The text keeps them apart anyway. The observation outranked the theory.

Vataja Shiro-roga: the Headache That Asks for Pressure and a Bandage (XXV.3)

A folded band and a dish of tila taila: the two objects the Vataja entry names as its own test.

The first of the eleven is described in a sentence that is almost entirely made of conditions:

Four clauses, and every one of them is a manoeuvre rather than an appearance. Nothing here about how the head looks; a great deal about what happens when you do something to it.

Without any apparent cause rules out the obvious — no blow, no fever, no wound. Worse in the night places it in Vayu’s own hours: the tridosha framework assigns the late-night and pre-dawn stretch to Vata, so a pain that sharpens as the night deepens is behaving exactly as Vayu behaves. And eases on fomentation confirms it, warmth being the direct opposite of Vayu’s cold and dry qualities.

But the clause that gives the entry away is eases on pressure, or on being bandaged. Vayu is the principle of movement, of emptiness, of the hollow and the dry — and something that answers to compression from a firm hand or a tightened turban is behaving like a space rather than a substance. Sushruta is using external pressure as a diagnostic instrument and reasoning from the response back to the category. Four bedside tests, no instrument, a category at the end of them: a physician could run this examination in a dark room with nothing but his hands and a length of cloth.

Pittaja Shiro-roga: Live Charcoal on the Scalp (XXV.4)

The second entry abandons manoeuvres and reaches instead for the most vivid simile in the chapter:

Note how precisely this is the photographic negative of the entry before it. The Vataja type is worse at night; this one is better at night. That one answers to warmth; this one answers to cold. Two entries defined against each other on the same two axes — deliberate construction, and how the whole chapter is built.

The simile itself — angara, live coals scattered over the scalp — is not describing intensity but texture: not one hot place but many, each burning on its own. That is the entire point of a simile in a manuscript that cannot carry an illustration. And the second clause, a sense of scorching vapour from the nostrils, is Pitta’s signature in the classical grammar — the hot, sharp principle, seated in the middle body but capable of rising, whose five functional divisions we walked through in our reading of the five Pittas. What matters is that the text is asking something a clinician can actually ask: does your breath feel hot?

Kaphaja and Tridoshaja Shiro-roga: the Head That Will Not Turn (XXV.5–6)

The third entry moves to weight:

Kapha in the classical grammar is heavy, cold, oily, sticky, slow — and every adjective in that verse is one of them, applied to a head. The most striking clause is cannot be turned about: not pain on movement but a kind of refusal, the head as an object too heavy to want to move. Sushruta has taken an abstract quality list and rendered it as a posture.

Bhishagratna preserves a small textual quarrel here: where our reading has the head covered in sticky mucus, some manuscripts read the palate, and that is the reading Madhava adopts. He concludes there is no real difference, since the word for head may include both palate and throat — a single Sanskrit compound argued over for a thousand years and settled in a footnote in Calcutta in 1911.

Then verse 6 handles the fourth type in a single clause, and does not pretend to more:

This is the honest entry: no new observation, no simile, no test, because when everything is deranged at once the picture is simply everything at once. Classical texts are often criticised for over-systematising; here is one declining to invent a distinction it could not see.

Raktaja Shiro-roga: When the Head Cannot Bear a Touch (XXV.7)

The fifth type is defined almost entirely by reference to the second, and then by one added sign:

Rakta and Pitta are close relatives in classical physiology — blood is held to carry Pitta’s heat — which is why so many raktaja conditions across the corpus look like their pittaja counterparts with something extra. Here the extra is exquisite tenderness of the scalp itself, and look what that single clause accomplishes as differential method. Both the Vataja and the Raktaja entries put the physician’s hand on the patient’s head, and they give opposite answers: under one, pressure eases; under the other, the lightest touch is unbearable. One manoeuvre, two opposite responses, two categories.

Kshayaja Shiro-roga: the Entry Where Every Measure Makes It Worse (XXV.8)

The sixth entry is, to a modern reader, the most surprising in the chapter, because it is a warning label:

Read that list of five again. Fomentation (sweda), fumigation (dhuma), errhine (nasya), emetic (vamana), blood-letting (rakta-mokshana). Those are not random: they are almost exactly the standard arsenal this compendium reaches for in head and upper-body disease — and the chapter says that in this one type, all of them make it worse.

Kshaya means waste, depletion, loss of substance. Dallana glosses vasa broadly — all the fatty substances of the body — and notes a variant reading in which the type arises from the waste of blood, vasa, Kapha and Vayu together, which he prefers. The logic holds either way: where the trouble is emptiness, every measure that empties further deepens it. Sweating, purging the head, inducing vomiting and taking blood all subtract.

This is a genuine contraindication, written into a diagnostic chapter by a tradition with no concept of a contraindication as a category. Somebody had watched a patient get worse under standard care, and thought hard enough about why to file it as a separate disease. That habit of mind is rarer and more valuable than any individual prescription in the book.

Krimija Shiro-roga: the Chapter’s Most Alarming Entry (XXV.9)

Two things stand out. The sensory description is interior — the pain is inside the head, not a throb or a burn but a sting, discrete and pointed. And, unusually for this chapter, the text pauses to editorialise: this disease is a dangerous one. The other entries mostly refrain from prognosis.

Krimi in classical Ayurveda is a wider category than the English “worm” suggests, covering visible parasites but also invisible agents held responsible for a range of conditions. What the tradition is doing here is filing a head disease that comes with bloody nasal discharge and a boring, stinging pain, and flagging it as serious. We are not going to gloss it as any modern diagnosis — that would be guesswork dressed as scholarship. We note only that the text singled it out for a warning, and that the sign it attached the warning to was bleeding.

Suryavarta: the Head Disease That Turns With the Sun (XXV.10)

Suryavarta is timed, not located: it rises with the sun, peaks with it, and lets go as it sets.

Here the chapter changes register completely. The first seven entries were named for causes; the next four are named for what they do. And the first of them is a clock.

Surya is the sun; avarta is a turning, a whirl, a revolution. There is a location — eye and eyebrow — but the whole weight of the entry rests on a twelve-hour arc: onset at dawn, crescendo at midday, release at dusk.

Consider what it took to write that sentence. Not one patient but many, over years, all reporting the same shape of day — and a physician disciplined enough to notice that the shape itself was the finding. A single headache that happens to start in the morning is nothing; a pattern that reproduces across patients, tied to the sun’s own arc, is a disease entity. Sushruta is describing what we would now call a circadian pattern, roughly fifteen centuries before there was a word for it.

Then the small, honest clause at the end: it generally abates on the use of cold articles, but sometimes on that of warm things as well. The chapter has spent five verses building a clean cold-versus-warm axis, and here it admits this entry does not obey it reliably. It reports the exception rather than forcing it into the system.

Anantavata: the Endless One, Beginning at the Nape (XXV.11)

This entry is a map. Where Suryavarta was defined by time, Anantavata is defined by a route: it starts at the nape, at the structures the text calls manya and ghata, and travels forward and upward to the eye, the eyebrow and the temple, then out to the cheek, which throbs. The verse tracks a pain across a face in order.

Ananta is the endless serpent of Indian cosmology, the coiled Shesha on whom the world rests, whose name literally means without end. To call a head disease Anantavata is to say two things at once: that the pain follows a long coiled path from the back of the neck around to the face, and that it does not stop. Classical disease names do this double work constantly, and are almost always worth unpacking rather than translating.

The last clause — Bhishagratna renders it as paralysis of the jaw-bone and the eye — is the most severe sign in the entry, and the point at which we stop paraphrasing and stay with the text. Loss of movement in a face is not a finding to speculate about across fifteen centuries. It is a finding that, today, sends a person to a hospital. See the note at the end of the next section.

Ardhavabhedaka: Half the Skull — and the Ancestry of the Word Migraine (XXV.12)

Ardha-avabhedaka: half-splitting. The oldest surviving name for a pain that takes one side of a head.

This is the entry the chapter is remembered for.

Take the name apart. Ardha is half. Avabhedaka comes from bhid, to split, to break, to cleave — the same root that gives bheda, a division, and bhedya, the surgical category of things that are to be incised. Ardhavabhedaka is the half-splitter: the thing that breaks one half of a head.

Now hold that beside the European history of the same observation. Greek medicine, working independently, arrived at hemikrania — hemi, half; kranion, skull. Half-skull. Latin took it as hemicrania; medieval French wore it down to migraine; English borrowed it and never gave it back. The word sitting in the pharmacy aisle today is, etymologically, the exact same sentence as the Sanskrit: half the head.

And the entry does not stop at the geometry. It adds giddiness — pairing the one-sided pain with a disturbance of balance, not as an afterthought but as part of the definition. Then comes the most sophisticated sentence in the chapter: the pain either follows no distinct periodicity, or recurs at a regular interval of ten days or of a fortnight. That is a text saying two things at once — recording that this condition comes in bouts rather than persisting, and refusing to over-specify, allowing that in some people the bouts arrive on a schedule and in others they do not. Getting a recurrence pattern into a disease definition at all, then correctly qualifying it as inconsistent, is a descriptive discipline genuinely rare in ancient medical writing of any tradition.

None of which means Ardhavabhedaka is a modern diagnosis. It is a first-millennium disease entity from a system with its own physiology and its own reasoning. What the parallel shows is not that the classical text anticipated modern medicine, but something more human: careful observers in two different worlds, given the same phenomenon, cut it at the same joint. Our essay on what modern medicine has and has not rediscovered in Sushruta works through several more of these convergences, and is careful about where they end.

Shankhaka: the Temple Pain the Text Calls Fierce as Death (XXV.13)

The chapter closes on its darkest entry.

Shankha is the conch — and also, in anatomical usage, the temple, the flat of the skull beside the eye. Shankhaka is the temple disease.

Everything about how this verse is written signals alarm. It abandons the chapter’s cool descriptive register, invokes the sages by name rather than simply stating, and concedes the failure of the profession itself — hard to subdue even by the joint advice of thousands of physicians — before closing on a simile the chapter has earned the right to use exactly once. Read structurally, it is the red flag: Sushruta spends eleven entries teaching a physician to sort head pain calmly by hour and by hand, then ends by naming the one where the correct response is not classification but urgency. Classical medicine had no word for triage. This verse is doing triage anyway.

What Actually Separates the Eleven: a First-Millennium Headache Diary

Set the eleven entries side by side and the chapter’s method becomes obvious. Almost nothing in it is anatomy. Almost everything in it is time, trigger, side and response to the hand.

Read the columns rather than the rows and the architecture appears. Column three is a clock: night, day, sunrise, sunset, ten days, a fortnight. Column four is a pair of hands: press here, bind this, warm it, cool it, do not touch. Column two is a small library of similes borrowed from ordinary life — coals, mucus, a sting, a splitting. That is a history-taking protocol. Strip away the doshic vocabulary and the questions underneath are: When does it come? How long does it last? Does it come back — how often? Which part of the head? Does anything make it better or worse? Those five questions are, almost verbatim, what a headache clinic asks a patient to record today, and for exactly the reason Sushruta needed them: because the pattern carries the information that the examination cannot.

Shiro-roga Pratishedha: How the Twenty-Sixth Chapter Answers (XXVI.1)

The manuscript closes Chapter XXV with its formula, and opens Chapter XXVI with another: “Now we shall discourse on the chapter which deals with the therapeutics of the diseases of the head” — the Shiro-roga Pratishedha. Having taught the reader to tell eleven things apart, the compendium now spends a chapter on what to do about each.

Everything from here on is described as history of medicine. These are physician-administered classical procedures from a first-millennium surgical text; several involve inducing vomiting, purging the head and taking blood. Nothing in this section is a suggestion and nothing in it should be attempted. It is here because the therapeutic half tells us what the diagnostic half does not: what the categories were for.

Which answers the obvious sceptical question. Why bother separating eleven headaches if you cannot see inside a head? Because the categories fork the treatment. Get the type wrong and you warm what should be cooled, or you purge someone the text says must not be purged. The taxonomy is load-bearing.

The Vataja Answer: Sneha, Milk and a Warmed Head (XXVI.2–5)

The chapter’s first move is a cross-reference, and a large one:

That is the compendium pointing at itself. Vata-vyadhi — the vast class of Vayu disorders the tradition calls rogaraat, the king of diseases — already has its own therapeutics elsewhere in the text, and the head chapter inherits them wholesale. Classical texts are built like this: a network of cross-references rather than a sequence of self-contained articles.

What follows is a shelf of snehas, the unctuous and warming register in its entirety. Mudga, kulattha and masha pulses taken unmixed; pungent, heat-making articles saturated with clarified butter, taken at night and followed by warm milk; sesamum oil or its paste. Externally: milk boiled with the Vayu-subduing drugs used lukewarm as a wash, and a plaster of the same drugs boiled in milk applied warm to the scalp — or, as alternatives, boiled fish, krishara (rice and sesamum) with saindhava salt, or chandana, utpala, kushtha and pippali finely powdered together.

Then the pharmacy proper, and its staging is the interesting part. An oil prepared with kulira serves for nasya after the fomentation. A ghrita is built in steps: milk diluted with half as much water is boiled with the paste of the Varunadi group until the water has gone; butter is skimmed from it when cool; the clarified butter from that is cooked again with the Madhura (sweet) group; and that is the errhine. Snaihika dhuma, the unctuous medicated smoke, is given when required, and Traivrita Ghrita and Bala Taila are prescribed as a draught, as an errhine, and for anointing, sprinkling and vasti-karma.

Notice what is happening across all of it. Every single measure is warm, oily, heavy or nourishing — the exact inverse of Vayu’s cold, dry, light, mobile qualities. And the milk instruction from verse 2 runs through everything like a refrain. Our reading of the Kshira Varga — the milk chapter of the Ashtanga Hridaya — sets out why milk sits at the top of the tradition’s nourishing register in the first place.

The Pittaja and Raktaja Answer: the Cooling Shelf (XXVI.6–7)

Milk, sugarcane juice, lotus, chandana: the Pittaja shelf is almost entirely cool, sweet and floral.

Because the Raktaja type was defined as the Pittaja picture plus tenderness, the chapter handles both together — and inverts the entire previous section.

Cooling plasters saturated with clarified butter go on the scalp; cooling head-washes are prescribed. For sprinkling: milk, the expressed juice of sugarcane, dhanyamla (fermented rice-gruel), mastu (curd-cream), and honey and sugar mixed in water.

The head-plaster for these types is worth reading as a list, because it is almost entirely a list of flowers and cool woods:

Reeds, water plants, two kinds of lotus, sandalwood, licorice root, powdered conch. It is a pond and a spice-shelf, ground into ghee. Every item on it belongs to the cool, sweet, heavy end of the classical pharmacology — and the plasters described for the Pittaja and Raktaja types of visarpa elsewhere in the compendium are recommended here too, another of those internal cross-references.

The section continues in the same register — the Madhura group tepid as plasters, sneha cooked with the same drugs as an errhine, clarified butter skimmed from milk used for snehana, and the jangala-animal preparations for errhine, vasti and meat-soup.

Set the two treatment sections beside one another and the symmetry is complete. The Vataja shelf is warm, pungent, heavy, oily. The Pittaja shelf is cool, sweet, floral, also oily. Both lean on ghrita and milk; they differ almost entirely in temperature and taste. That is the whole logic of the chapter in one comparison — and it is why the eleven-fold sorting in Chapter XXV had to be done carefully.

The Kaphaja Answer: Shiro-virechana and the Drying Register (XXVI.8)

For the Kaphaja type — the heavy, cold, sticky, immovable head — the chapter turns to the third register: not warming, not cooling, but drying and clearing.

Kapha-subduing measures are named directly: strong emetics, head-purgatives (shiro-virechana) and gargling. The transparent upper part of clarified butter is given to drink, and fomentation applied frequently. The head-purgation uses the pith of madhuka wood, or mesha-shringi and ingudi bark; vartis of the same barks serve for smoking; snuffs of powdered katphala are taken. A plaster of sarala, kushtha, sharngashta, devadaru and rohisha, pasted with alkaline water and mixed with saindhava salt, goes on lukewarm. The diet is cooked barley or shashtika rice.

The whole shelf is sharp, bitter, pungent, alkaline and dry — the mirror image of Kapha’s heavy, cold, oily, sticky qualities. And the pattern across all three sections is now unmistakable: the tradition works by opposite quality. Identify the quality that has gone wrong, then apply its inverse. That single principle organises everything in Chapter XXVI, and it is why Chapter XXV had to be so careful about telling eleven things apart.

Murdha Taila: Why the Daily Routine Puts Oil on the Head

The daily habit sitting behind the whole chapter: oil, applied to the head, on an ordinary morning.

Step back from the clinical chapters and one ordinary thing is visible behind all of them. Almost every measure Chapter XXVI reaches for is an intensified version of something the tradition already recommends doing every day, to a perfectly well person. The head-plaster is an intensified shiro-lepa; the errhine an intensified pratimarsha nasya, the small daily dose of oil in the nostrils; the oiled and warmed head an intensified murdha taila — the anointing of the head that the classical daily routine regards as unremarkable, like brushing the teeth.

The Dinacharya chapters place head-anointing among the ordinary items of a morning, alongside the tooth-twig, the tongue-scraper and the bath; Vagbhata gives it a run of verses in the Ashtanga Hridaya’s Sutrasthana, and the wider practice of oil across the body — abhyanga — is among the most persistent habits the tradition has handed down. Somewhere between the classical text and today, the clinical procedure became a household custom: the champi, the Sunday oiling, the grandmother with warm oil and a firm hand.

We are not going to claim that habit does anything to any of the eleven conditions above — it does not, and the text does not say it does. What is true, and quite enough on its own, is that oiling the head is one of the oldest continuously practised personal-care customs on the subcontinent.

Reading the Eleven Shiro Rogas With Modern Eyes

Three things are worth saying plainly at the end of a chapter like this one.

First: the eleven Shiro Rogas are not eleven modern diagnoses. It is tempting to line them up against a modern list and hand out equivalences, and it is bad history in both directions. Sushruta’s categories rest on a physiology of doshas, dhatus and srotas that does not map onto modern pathophysiology. Ardhavabhedaka is not a synonym for anything in a modern classification; it is a first-millennium disease entity that happens to have been cut at a joint later observers also found.

Second: the method is more impressive than the content. The lasting achievement of Chapter XXV is not any individual entry but the decision to sort head pain by time, trigger, side and response when there was nothing else to sort it by — and then to hold the distinctions even where the theory could not account for them. Suryavarta and Ardhavabhedaka are both, by the chapter’s own admission, tridoshaja; the system says they are the same thing; the text keeps them apart because a physician kept seeing that they were not. Observation outranking framework is the beginning of every clinical science there has ever been.

Third: the honest gaps matter. The chapter admits that Suryavarta sometimes answers to warmth and sometimes to cold, that Ardhavabhedaka has no reliable periodicity, that the Tridoshaja type is simply everything at once, that in the Kshayaja entry the standard toolkit can make things worse, and that with Shankhaka the profession may simply fail. A text confident enough to record its own exceptions and its own failures is a good deal more trustworthy than one that is not.

What This Article Is Not

Daily Care in a Classical Spirit

Our own shelf keeps a much humbler ledger. These are everyday personal-care preparations made in the spirit of the tradition’s daily customs — a wash, an oil, a few drops of something cool — offered for what they are and never as more.
