Dravadravya Vijnaniya: The Chapter Where Ayurveda Weighs the Oils of Daily Life

Every great kitchen tradition has its quiet philosophers, but few wrote them down as carefully as India did. In the Ashtanga Hridaya — the most elegant and best-loved of the classical Ayurvedic texts, composed by Vagbhata around the seventh century — the fifth chapter of the Sutrasthana is given over entirely to the liquids we live on. Its name is the Dravadravya Vijnaniya Adhyaya: the chapter on knowing the fluid substances. It moves, group by group, through water, milk, sugarcane, honey, oils and more, and it treats each not as a mere commodity but as a substance with a character — a taste, a warmth or coolness, a heaviness or lightness, and a particular effect on the body's three humours.

We have already walked two of those groups in companion guides: first the Jala Varga, the classical rules of water, and then the Kshira Varga, the whole family of milk, curd, buttermilk and ghee. This article takes up one of the most useful groups of all — the one every Indian kitchen and every Ayurvedic pharmacy leans on daily: the Taila Varga, the group of oils. Sesame, castor, mustard, neem, vibhitaka and the animal fats each get their own reading, and behind them all sits one of Ayurveda's most important ideas, the idea of Sneha — the unctuous, the oily, the soft. What follows is Vagbhata's oil shelf, read bottle by bottle, in plain modern English. It is offered as materia-medica heritage and the classical science of substances, for interest and understanding — not as medical advice.

The readings here are drawn from the Taila Varga of the Dravadravya Vijnaniya — the fifth chapter of the Sutrasthana of Vagbhata's Ashtanga Hridaya, one of the founding texts of Ayurveda

One small word before the shelves, because Ayurveda's whole approach to any substance turns on it. When the classics assess a food or oil they are really asking a few questions of it: what is its rasa (its taste — sweet, sour, pungent, bitter, and so on), its virya (its potency — essentially whether it warms or cools the body), its vipaka (its effect after digestion), and its guna (its quality — heavy or light, oily or dry, sharp or dull). This is the grammar in which every entry below is written; we unpack it fully in the guide to rasa, virya and vipaka and in the tradition's love of the six tastes (shad-rasa). Keep it in mind, and the Taila Varga reads less like a list and more like a conversation about how oils behave.

Sneha and Taila: What Ayurveda Means by an “Oil”

To understand the Taila Varga you first have to meet a word that runs like a golden thread through the whole of Ayurveda: Sneha. In everyday Sanskrit sneha means both oiliness and affection — the same word for the softness of oil and the softness of love — and that double meaning is not an accident. To the classical mind, the unctuous quality is a kind of tenderness the body needs: it soothes dryness, it loosens what is stuck, it carries nourishment inward, and it steadies the restless, dry, mobile humour, Vata. When the texts speak of snehana, oleation, they mean the whole art of using this quality wisely, inside and out.

Classical Ayurveda counts four great Sneha — four kinds of unctuous substance — and it ranks them in a settled order of merit. First is Ghrita (ghee), the finest and most refined; second is Taila (oil, and above all sesame oil); third is Vasa (muscle fat); and fourth is Majja (bone marrow). The Charaka Samhita sets out this ranking in its great oleation chapter (Sutrasthana, Chapter 13, the Snehadhyaya), and the Ashtanga Hridaya echoes it in its own Snehavidhi (Sutrasthana, Chapter 16). Ghee we have already praised in the guide to Charaka's chapter on oleation and the fats and in the reading of cow's ghee in the Bhavaprakasha. Here, in the Taila Varga, it is the second of the four — Taila, the true oils — that takes centre stage.

And the chapter opens with a principle so sensible it could hang over any modern pantry. Generally, Vagbhata says, an oil carries the qualities of the substance it is pressed from. Sesame oil behaves like sesame; mustard oil like mustard; the oil of a bitter seed stays bitter. It sounds obvious, yet it is quietly profound: it means there is no such thing as “oil” in the abstract, only this oil from this seed, with this character. It is the same instinct that makes a good cook choose mustard oil for one dish and sesame for another, and it is why the classical texts never lumped all fats together but read each on its own terms.

Tila Taila: Why Sesame Oil Is the King of the Taila Varga

Ayurveda begins its oil shelf, as any traditional household would, with sesame — Tila taila, gingelly oil, til ka tel. And it begins with a crown. When the classics say taila without qualification, they almost always mean sesame oil, so completely does it stand for the whole category. The Ashtanga Hridaya's verdict is blunt and warm at once: of all the oils, sesame oil is the best (tailanam taila-uttamam, in the spirit of the classical phrase). The Sushruta Samhita, in its own great chapter on fluid substances (Sutrasthana, Chapter 45, the Dravadravya-vidhi), agrees, giving sesame oil pride of place among the tailas and lingering on its many uses.

Why so exalted? Because of a rare and prized combination of qualities. Sesame oil is tiksna (sharp, penetrating), vyavayi (quick to spread and pervade), sukshma (subtle, fine) and ushna in potency (warming). Being penetrating and subtle, the texts say, it works its way into the smallest channels of the body (srotas) that thicker, duller substances cannot reach — which is exactly why it became the master base for the entire classical pharmacy of medicated oils. When a vaidya wanted to carry the virtue of a herb deep into the tissues by massage, sesame oil was the vehicle of choice. It is Vata-settling above all, yet, unusually, the tradition notes it does not greatly increase Kapha despite its unctuousness, and that it is balya (strengthening) and tvachya (valued for the skin).

Tila taila, sesame oil: sharp, penetrating, subtle and warming. The Taila Varga crowns it the best of all oils, and the classical pharmacy made it the master base for medicated oils and for abhyanga, the daily self-massage

There is one more famous quality the classics loved to point out: sesame oil is said to be at once balya (strength-giving) and unusually kind to a person's build — it was held to help slighten a heavy frame and to nourish a thin one, meeting each where it was. And it carries a beautiful signature note, the sesame plant's own hardiness: Tila is the crop that grows in poor soil and dry seasons, and the oil was felt to lend some of that steadiness to the body it was rubbed into. All of this is why sesame oil sits at the very heart of abhyanga, the daily oil self-massage, and of snehana, the classical oleation therapies.

But — and this is the mark of an honest text — the praise is not blind. The very same passage adds a striking caution: taken carelessly and in excess, the classics say, raw sesame oil is not universally kind — used to great excess it was thought unsuited to the eyes and able to disturb the skin, precisely because it is so sharp and heating. This is not a contradiction; it is nuance. And it points to one of the most important ideas in the whole of Ayurvedic pharmacy: samskara, the transformation a substance undergoes through processing. A raw oil is one thing; the same oil gently cooked with cooling, skin-friendly herbs becomes quite another, its sharpness tempered, its character redirected. The classical medicated oils exist for exactly this reason — to take sesame oil's incomparable power to penetrate and to steer it, herb by herb, toward a chosen purpose.

Eranda Taila: Castor Oil in the Ashtanga Hridaya

Next on the shelf is one of the most distinctive oils in the whole materia medica: Eranda taila, castor oil, pressed from the mottled seeds of the castor plant (Eranda, Ricinus communis). If sesame is the balanced king, castor is the specialist — thick, slow, unmistakable, and reserved by the classics for particular tasks. Vagbhata reads it with care: castor oil, he notes, carries tikta (bitter), katu (pungent) and a touch of madhura (sweet) in its taste, and above all it is sara (mobile, flowing) and guru (heavy) in quality.

That single word sara — mobile, moving-things-along — is the key to castor's classical reputation. Where sesame penetrates, castor moves; it is the great Vata-directing oil, the one the old texts reached for when the downward-moving currents of the body needed gentle encouragement. The Ashtanga Hridaya associates Eranda taila, in the language of classical materia medica, with the management of vardhma (a classical term for certain swellings), with disorders of Vata and Kapha, and with easing pain and heaviness about the hips, the low back and the abdomen. A red-seeded variety (Rakta eranda) is described as sharper, hotter and more slippery than the common kind, and rather less pleasant in smell — a good example of how finely the tradition graded even the sub-types of a single oil.

Eranda taila, castor oil: bitter-pungent, heavy and sara (mobile). The classics prize it as the great Vata-directing oil — a specialist, read by Vagbhata quite separately from the everyday cooking oils

A word of plain sense is owed here, because castor oil is a substance modern readers may know as a folk laxative. These are classical descriptions of how the old physicians categorised the raw oil in their materia medica; they are history and heritage, not a home prescription, and castor oil taken internally is emphatically not something to experiment with on one's own. The point worth carrying away is a scholarly one: the tradition understood that different oils do different things — that the light penetrating oil and the heavy mobile oil are not interchangeable — and it filed each in its proper place. That refusal to treat all fats as one is castor's real lesson in the Taila Varga.

Sarsapa Taila: Mustard Oil in the Classical View

If any oil rivals sesame for a place in the everyday Indian kitchen — especially across the north and east — it is mustard oil, Sarsapa taila, sarson ka tel, pressed from the tiny round seeds of the mustard plant. The Ashtanga Hridaya reads it in a single, vivid stroke: mustard oil is katu (pungent) in taste, tiksna (sharp) and laghu (light) in quality, and ushna (heating) in potency. Anyone who has smelt raw mustard oil warming in a pan — that unmistakable bite that catches in the nose — has met its tiksna, ushna nature directly. The classics do not describe it; they simply name what your own senses already know.

Because it is pungent, sharp and hot, mustard oil is read as a strong settler of the two cool, heavy humours: it mitigates Vata and Kapha, the tradition says, cutting through dullness and damp where a gentler oil would not. In the older language of materia medica it is associated with the external care of kotha, kustha (a broad classical category of skin conditions), vrana and krimi (classical categories, not modern diagnoses), which is exactly why, for centuries, mustard oil was the workaday massage and cooking oil of choice in the colder, damper regions where Kapha tends to gather. Its heating, mobilising character suited the climate and the constitution. The same passage adds a careful note that it can, in excess, disturb the finer tissues and the shukra — another reminder that in Ayurveda a virtue and a caution always travel together.

Sarsapa taila, mustard oil: pungent, sharp, light and heating. A strong settler of the cool, heavy humours — the reason it became the workaday oil of India's colder, damper regions

There is a beautiful piece of practical wisdom folded into all this. The classical grading of oils is, at heart, a map of which oil suits which person, place and season — the same map that runs through the whole of Vagbhata's science of substances and their properties (dravya-guna). A heating, light oil like mustard for a cold, damp, heavy constitution; a balanced, penetrating oil like sesame for the dry and mobile; a cooling, refined fat like ghee for the hot and sharp. Read this way, the Taila Varga is not a ranking of “good” and “bad” oils at all. It is a lesson in matching.

Nimba, Aksa and the Rest: Neem, Vibhitaka and the Specialised Oils

Beyond the three great household oils, the Taila Varga surveys a handful of more specialised pressings, each with a narrow and particular character. Here the chapter reads less like a kitchen guide and more like an apothecary's shelf.

First among them is Nimba taila, neem oil, pressed from the seeds of the neem tree (Nimba, the great bitter of the Indian materia medica). Vagbhata reads it as tikta (bitter) in taste, and — interestingly — not excessively heating, which sets it apart from the sharper oils. In the classical language it is associated with the external care of krimi and kustha (those broad classical categories of the skin and of small organisms), and with settling Kapha. Neem's bitterness is legendary across the whole tradition, and we follow it in the guide to neem's classical uses for skin and hair and in the older reading of neem oil itself. As with every entry here, these are scholarly descriptions of the raw oil's traditional category, not a home remedy for any condition.

The specialised oils: Nimba taila (neem), bitter and cooling, and Aksa taila (vibhitaka), the sweet, hair-friendly oil — the apothecary's end of the classical oil shelf

Next, and a delight for anyone who cares about hair, is Aksa taila — the oil of Vibhitaka (bahera, Terminalia bellirica), one of the three fruits of the famous Triphala. Vagbhata gives it a lovely, gentle reading: vibhitaka oil is madhura (sweet) in taste, sita (cooling) and guru (heavy) in quality, and — the line that has kept it in the tradition — it acts as a hair tonic (keshya), settling both Pitta and Vata. It is a rare cooling, sweet oil in a group of sharp, heating ones, and its association with the hair is why the classical hair oils so often reached for the vibhitaka fruit.

The chapter closes its oil survey with two humbler pressings gathered together: Uma taila (linseed, from Uma, Linum usitatissimum) and Kusumbha taila (safflower, from Kusumbha, Carthamus tinctorius). Vagbhata reads them plainly and without flattery: both are ushna (heating) in quality, both were thought able to disturb the skin with heavy use, and both tend to increase Kapha and Pitta. It is a small, honest coda — the reminder that not every oil earns a crown, and that a good text says so.

Vasa and Majja: The Animal Sneha, and the Chapter's Wider Sweep

Having finished the plant oils, the Taila Varga turns briefly to the last two of the four classical Sneha: Vasa (muscle fat) and Majja (bone marrow). These belonged to the world of the classical physician far more than to the kitchen, and Vagbhata reads them together. Both, he says, settle Vata and tend to increase Kapha and Pitta; both give strength to the body; and — true to the chapter's founding principle — each carries the qualities of the animal it comes from, just as the fat does. They are the richest and heaviest of the four Sneha, reserved for the narrowest uses, and named here to complete the family of unctuous substances rather than to be taken up lightly.

And with that, Vagbhata's fifth chapter draws toward its close. In the honest manner of an ancient encyclopaedia, the Dravadravya Vijnaniya does not stop at oils; it goes on to catalogue honey (Madhu varga), then a long survey of fermented preparations (Madya varga), and finally, in the exhaustive style of old materia medica, a group of animal-derived substances (Mutra varga). Those last two groups belong squarely to the history of classical pharmacology and to a very different world of practice; they are not foods or self-care in any modern sense, and they fall well outside the scope of this gentle guide to the oils. We note them only for completeness, so that a reader knows exactly where the oil shelf sits within the whole of Vagbhata's chapter — and then we return, as any household would, to the oils themselves.

Abhyanga and Snehana: How the Taila Varga Lives in Daily Practice

A chapter on oils would be a dry thing indeed if it stayed on the page, and the Taila Varga never did. Its living form is Abhyanga — the daily oiling of the body — and Snehana, the wider art of oleation of which abhyanga is the gentlest, most everyday expression. This is where the classical reading of oils steps out of the manuscript and into the bathroom of an ordinary morning.

The tradition's affection for daily oiling is hard to overstate. A well-loved classical image holds that the person who oils the body regularly is not easily overtaken by tiredness, and that the body, like a well-oiled leather strap or a smooth axle, wears more softly with the years. Vagbhata places abhyanga among the foundational daily duties in his Dinacharya, singling out the head, the ears and the feet as the parts most worth a daily touch of oil. And the oil the tradition reaches for first, of course, is the king of the Taila Varga: warm Tila taila, sesame oil, worked gently into the skin before a warm bath, so that the warmth helps the oil's tiksna, sukshma nature do its quiet work.

Snehana in the fuller sense — the deliberate, staged oleation that prepares the body for the classical cleansing therapies — is a clinical procedure and belongs with a trained physician, and we describe it only as heritage in the guide to snehana and classical oleation. Oil also has a place in the care of the head and nose through Nasya, where a medicated oil such as Anu taila is used in the classical way. But the everyday heart of it all — the part that asks nothing but a few minutes and a little warm oil — is simple abhyanga: a small, steadying kindness the classics counted among the pleasures of a well-kept day. It is, in the end, the most human thing in the whole chapter.

The Taila Varga at a Glance

The classical readings of the oils, gathered into one view. As always, these are materia-medica descriptions offered as heritage — a beautiful old way of organising the character of substances — and not medical advice or a claim about any product.

A Gentle Rhythm of Oil in Everyday Self-Care

There is one honest place a wellness brand belongs in a chapter like this, and it is a modest one: in the small, pleasant rituals of an ordinary well-kept day — the daily touch of oil on the hair and skin that an Indian household has always valued, built around exactly the heritage substances of this chapter. Nothing below is offered as a cure, a treatment or a remedy for any condition. These are simply time-honoured, everyday oils that can find a natural place in the gentle daily rhythm the classics prized.

The honest place for a wellness brand in a story like this is only in the small comforts of an ordinary day: a little warm oil for the hair, a drop of facial oil at night, a calm bath. Gentle heritage — part of a well-kept daily rhythm, and nothing more

The most everyday of these is a good hair oil, the living heir of the keshya (hair-friendly) tradition the Taila Varga hints at with its sweet, cooling Aksa taila. A warm scalp massage with a herbal oil is abhyanga at its simplest and most pleasant.

A second belongs to the classical love of a facial oil — the fine, precious night oil the tradition prized for the skin's clarity and glow. The most celebrated of these is Kumkumadi Tailam, the saffron-infused facial oil whose very name ends in tailam — oil — a direct descendant of the Taila Varga's world.

And the third is the simplest oil of all, the one the modern kitchen and bathroom share alike: a pure cold-pressed coconut oil. Though coconut oil is not one of the seven pressings Vagbhata names in this particular chapter, it belongs wholly to the same living tradition of the honest, single-source oil — the very thing the Taila Varga teaches us to value.

That is the whole of the honest place for any of this: a few small, pleasant comforts within a well-kept day. Vagbhata would recognise the instinct — his entire chapter, after all, is about tending to the ordinary substances of the household with care, one wholesome choice at a time.

Reading the Taila Varga With Modern Eyes

How should a thoughtful reader in our own century hold an oil-chapter like this one — neither swallowing it whole nor waving it away? As always with the classical corpus, the honest course is to separate what still speaks from what belongs to its age, and to say plainly which is which.

What still speaks is a good deal. The founding principle — that an oil carries the character of its source, and that there is no generic “oil” but only this oil from this seed — is simply true, and truer than the flat modern habit of judging all fats by a single number. The insistence that oils differ by climate and constitution (a light heating oil for the cold and damp, a balanced one for the dry) is sound, humane practical wisdom. The reverence for where the oil comes from and how it is pressed anticipates the whole cold-pressed, single-origin conversation of today. And the ancient love of abhyanga, a few unhurried minutes of warm oil on the skin, needs no theory at all to justify it: as calm, as care, as a small daily kindness, it has quietly outlived every fashion.

And what belongs to its age must be said just as plainly. The language of rasa, virya and the three humours is a model of its time, an elegant way of organising experience, not a description of fatty acids, smoke points or oxidation; it did not know the molecule, and it is no substitute for it. Real, important facts sit outside its frame: that some of these oils are for the skin only and not the plate; that a few classical oils, castor above all, must never be taken internally on a whim; that modern nutrition has its own well-founded views on which cooking oils suit which purpose, and that these should guide the kitchen. None of the classical praise of any oil changes any of that, and none of it is medical advice. We gather more of these honest convergences and cautions in the guide to Vagbhata's classical diet, read for the modern table.
