Later compendium (sangraha grantha)
Yogaratnakara
योगरत्नाकरalso written Yogaratnakar
A late Ayurvedic compendium of tried formulations, best known for teaching the physician how to read the patient through the eightfold examination.
Era
Commonly dated to the mid-17th century CE, often around 1676
Author
Unknown (anonymous compiler)
Scope
Two khandas (Purva and Uttara), arranged by topic rather than a fixed count of numbered chapters
The Yogaratnakara belongs to the later stream of Ayurvedic writing, the age of the sangraha granthas or compendia, composed long after the great classical samhitas. It is commonly dated to the mid-17th century CE, with many sources pointing to around 1676, and scholars placing it broadly across the 17th to 18th century. By this time Ayurveda had a vast inherited literature, and the need of the hour was not new theory but a reliable, practical gathering of what worked.
That is exactly what the Yogaratnakara set out to be. Its very name, roughly the ocean or mine of yogas (formulations), announces the intent: to collect the tested recipes, diagnostic methods, and treatments scattered across Charaka, Sushruta, Vagbhata, Sharngadhara, and other authorities, and to arrange them so a physician could actually use them at the bedside. It is a compiler's book, and it wears that role with quiet confidence.
A foundation, not a footnote.
The Yogaratnakara matters because it is one of the most practical and widely consulted of the later Ayurvedic texts. Where the ancient samhitas build the theory of medicine, this compendium is where a practitioner reaches for a formulation, a dietary rule, or a way to confirm a diagnosis. Its formulations are still cited and prepared today, which is the truest test of a text: it is not a museum piece but a working reference.
Its greatest single contribution is diagnostic. The Yogaratnakara gives the clearest classical account of the ashtavidha pariksha, the eightfold examination of the patient, and it is largely through this text that the method became standard teaching. It also carries a detailed treatment of nadi pariksha, pulse diagnosis, describing how the pulse shifts under each dosha and even likening those movements to the gaits of animals to make the reading memorable.
Just as important is its temper. The Yogaratnakara insists that treatment begins with correct diagnosis (vyadhi vinishchaya), that the physician must examine both the patient (rogi) and the disease (roga) before reaching for a remedy, and it pairs every treatment with pathya and apathya, the foods and habits to keep and to avoid. That is Ayurveda at its most everyday and most trustworthy.
Two khandas (Purva and Uttara), arranged by topic rather than a fixed count of numbered chapters
The text is arranged not into numbered chapters but into two large halves, each covering a broad territory of practice.
Purva Khanda (the first half)
The foundation and general medicine. It opens with the auspicious invocation and the basic concepts of Ayurveda, then examination of the patient and the disease, the ashtavidha (eightfold) examination, the signs of curable and incurable cases, the tridosha, ama, the marks of health and the signs of approaching death, weights and measures, the science of substances and foods, the five forms of decoction, and the processing of minerals. It then moves through the causes, types, treatment, and diet for the common internal diseases, from fever (jvara), diarrhoea (atisara), and grahani to piles, weak digestion, worms, anaemia, and bleeding disorders.
Uttara Khanda (the second half)
The specialised branches. It covers the shalakya diseases of the head and senses, the ear (karna roga), nose (nasa roga), and eye (netra roga), and continues into the diseases of women (stri roga), aphrodisiac and reproductive therapy (vajikarana), rejuvenation (rasayana), the care of children (bala roga), and the treatment of poisoning (visha chikitsa).
Read end to end, the Yogaratnakara is an encyclopaedia of practice. It begins with how to know a patient, the eightfold examination and the reading of the pulse, urine, stool, tongue, voice, touch, eyes, and general form, and only then turns to what to do about what it finds. This order is deliberate: the book trusts diagnosis before treatment, always.
From there it becomes a treasury of formulations. Herbal decoctions, powders, medicated ghees and oils, and processed mineral preparations are set out disease by disease, each with its indications and, crucially, its accompanying diet and conduct. The pairing of remedy with pathya (what suits) and apathya (what harms) runs through the whole text, a reminder that in Ayurveda the medicine and the meal are never separate.
The second half widens the scope to the specialties, eyes, ears, and nose, the health of women and children, rejuvenation, and toxicology, so that between its two volumes the compendium touches nearly the whole span of clinical Ayurveda. It is theory made ready for use.
Notable for
- The clearest classical statement of the ashtavidha pariksha, the eightfold examination of a patient
- The eight readings it made standard: pulse (nadi), urine (mutra), stool (mala), tongue (jihva), voice (shabda), touch (sparsha), eyes (drik), and general form (akriti)
- A detailed teaching on nadi pariksha, pulse diagnosis, including how each dosha moves the pulse
- A vast, still-used collection of formulations gathered from the earlier classical authorities
- Consistent pairing of every treatment with pathya and apathya, the diet and conduct that support it
- A practical, bedside orientation that keeps diagnosis (vyadhi vinishchaya) ahead of remedy
Ancient text, everyday ritual
This is where your rituals come from.
The Yogaratnakara is a quiet argument for attention. Before it prescribes anything, it teaches the physician to look, at the pulse, the tongue, the eyes, the way a person holds themselves, and to let the body tell its own story first. That habit of daily, patient observation is the same one a person can turn on themselves: noticing the coating on the tongue in the morning, the steadiness of the pulse, the quality of digestion, and adjusting the day accordingly.
It also carries, in its constant pairing of remedy with pathya and apathya, the deepest ritual truth in Ayurveda: that what you eat and how you live are themselves the medicine. A formulation from this text was never meant to work alone. It came with a way of eating and a way of living around it. That is why the small daily rituals matter. They are not separate from healing; in the Yogaratnakara they are half of it.

Good to know
Who wrote the Yogaratnakara?+
It is anonymous. The compiler never named himself anywhere in the text. Some scholars have tentatively suggested a Jain scholar (a name read as Narayana Sekhara or Nayana Sekhara), but this is uncertain and not settled. It is best understood as a compilation of earlier authorities rather than one author's original work.
How old is it?+
It is a later text, commonly dated to the mid-17th century CE, often placed around 1676, with scholars situating it broadly in the 17th to 18th century. It was composed long after the ancient samhitas and draws its material from them.
What is the Yogaratnakara best known for?+
Two things: its diagnostic teaching and its formulations. It gives the clearest classical account of the ashtavidha pariksha (the eightfold examination) and a detailed treatment of nadi pariksha (pulse diagnosis), and it is a large, practical treasury of tested formulations arranged for everyday clinical use.
How is it organised?+
Into two halves rather than numbered chapters. The Purva Khanda covers basic concepts, examination and diagnosis, and general internal medicine; the Uttara Khanda covers the specialties, eye, ear and nose, women's and children's health, rejuvenation, aphrodisiacs, and toxicology.
