## How it is translated, and whether the translation holds

Each rendering is given with the source that uses it. The assessment is ours.

### Five diagnostic criteria

WHO international standard terminologies on Ayurveda (2022) · ITA-4.3.2 (nidānapañcakaḥ) · standards body

WHO's head term. Full description: 'The fivefold factors that help in the understanding and diagnosis of a disease, including its etiology, prodromal symptoms, signs and symptoms, pathogenesis and aggravating and relieving factors.' Note WHO's fifth item is 'aggravating and relieving factors', a history-taking notion, while it defines upaśaya at ITA-4.5.6 as an inference from a deliberate therapeutic trial. WHO is inconsistent with itself here.

### Disease assessment

WHO international standard terminologies on Ayurveda (2022) · ITA-4.3.1 (rogaparīkṣā) · standards body

The immediately preceding entry, and the activity the pañcaka serves: 'The process of investigating a disease: it is conducted by applying the five diagnostic principles.' WHO's phrase for the set here is 'the five diagnostic principles', a third wording.

### The ascertainment of disease is to be had from 'Nidana', 'Purva-rupa', 'Linga', 'Upacaya', and 'Samprapti.'

Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain) · Nidana Sthanam, Lesson I · public-domain translation

Kaviratna does not use a collective name at all. He renders the operation ('ascertainment of disease') and lists the five. His 'Upacaya' is an OCR degradation of 'upaçaya'; the hyphen in 'Purva-rupa' is a line break in the scan.

### five diagnostic tools

In-copyright comparator. The same page adds a point no standard records: 'Knowledge of all these five is not essential for the diagnosis of every disease. Many can be diagnosed by knowing any one or two, sometimes all the five are necessary.'

### Five means of understanding the diseases

easyayurveda.com rendering of Madhava Nidana 1.4 · MN 1.4 · modern textbook website

In-copyright comparator. 'Means of understanding' rather than 'criteria' or 'tools', a third framing.

## The classical passages

### Charaka Samhita Nidāna Sthāna 1 (Jvara Nidāna):6, checked against the source

> तस्योपलब्धिर्निदानपूर्वरूपलिङ्गोपशयसम्प्राप्तितः||6 ||

tr. none (Sanskrit mūla) · https://www.carakasamhitaonline.com/index.php?title=Jwara_Nidana

The locus classicus of the five. Note precisely what it does and does not say: it names nidāna, pūrvarūpa, LIṄGA, upaśaya, samprāpti as the means of upalabdhi (apprehension) of disease. It uses liṅga, not rūpa. And it does NOT use the word pañcaka. Retrieved and string-matched by me; the page prints the numeral as ||6 || in Arabic rather than Devanagari at this verse.

### Charaka Samhita Nidāna Sthāna 1 (Jvara Nidāna):6 (standard/Trikamji, confirmed by the Sanskrit ||6 ||). UNNUMBERED in Kaviratna: this passage lies in the unnumbered stretch between his aphorisms 2 and 4, which spans five standard aphorisms (5 to 9), so his missing 3 cannot be assigned to it., checked against the source

> The ascertainment of disease is to be had from 'Nidana', 'Purva->rupa', 'Linga', 'Upacaya', and 'Samprapti.'

tr. Avinash Chandra Kaviratna · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt

Public-domain English for the same verse. The '>' is a scan artifact at a line break and is preserved verbatim.

### Ashtanga Hridaya Nidāna Sthāna 1 (Sarvaroga Nidāna):2, address only, nothing quoted to check

Vagbhata states the set in a single verse and, unlike Charaka, uses RŪPA rather than liṅga as the third member. Devanagari mūla and verse number sighted on the retrieved page; not quoted per the rule for this text.

### Madhava Nidana 1 (Pañca Nidāna Lakṣaṇa):4, checked against the source

Madhava Nidana chapter 1 (Pancha Nidana Lakshana) enumerates the five means of understanding disease and names the set nidana-panchaka. LOCATED, NOT QUOTED: no verse-numbered Sanskrit Madhava Nidana was retrievable, so the chapter is right and the verse number is not established. Nothing here is quoted, because the only verbatim text previously carried was a sentence lifted from a 2023 website, which COPYRIGHT.md allows under neither clause.

## The concept record for this term

A term entry answers what the word means. It does not answer whether the thing the word
names is settled, and often it is not. That is what the concept record is for: it sets out
the questions on which the sources disagree about this term, with each position attributed,
and states what is not established.

- [Nidana-panchaka (the five-fold diagnostic frame)](https://nighantu.ageayurveda.com/concept/nidana-panchaka/)

## Where this term does work in the theory

One concept record names this term as one of its components, and glosses it there as follows.

- **[Disease classification in Ayurveda (vyadhi-vibhaga)](https://nighantu.ageayurveda.com/concept/disease-classification/)** (as nidana-panchaka): The five diagnostic limbs (nidana, purvarupa, rupa, upashaya, samprapti) which classify the evidence for a disease rather than the disease itself; systematised in Madhava Nidana chapter 1

## Not to be confused with

- **nidāna.** Its first member and also its name. The set has no standalone name in Charaka's verse; nidāna-pañcaka is a later coinage.
- **ṣaṭ-kriyākāla.** Sushruta's six-stage temporal scheme (sañcaya to bheda). The pañcaka is a checklist of evidence types to be gathered; kriyākāla is a sequence of stages in time. Bhishagratna's Sūtra 21 develops the second with no mention of the first.
- **trividha parīkṣā / daśavidha parīkṣā.** Methods of examination, how the physician obtains information (perception, inference, testimony; ten factors of the patient). The pañcaka is what the information is about. Charaka keeps them in different sthānas.
- **aṣṭasthāna parīkṣā.** The eightfold clinical examination (pulse, urine, stool, tongue, and so on). A later scheme, not classical in Charaka, and routinely presented alongside the pañcaka as though the two were the same kind of thing.
- **rogaparīkṣā / rogaviniścaya.** The activity and its endpoint. WHO codes these separately at ITA-4.3.1 and ITA-4.1.1. The pañcaka is the instrument, not the act or the conclusion.

## Renderings that do not hold

- the five diagnostic criteria. WHO's own head term, but 'criteria' implies each member is a test with a threshold. Four of the five are descriptive categories of evidence; only upaśaya involves anything like a decision rule.
- five-fold diagnosis. Suggests five kinds of diagnosis rather than five sources of evidence for one diagnosis.
- Ayurvedic differential diagnosis. Only upaśaya is differential in operation. The other four are not comparative.
- pentad of diagnosis. Reads as a fixed obligatory set, which the Ashtanga Hridaya commentary tradition denies: the retrieved AH page states that knowledge of all five is not essential for every disease.

## Open questions

Recorded rather than resolved.

- Where the compound nidāna-pañcaka first appears. It is NOT in Charaka Ni. 1: I searched the retrieved Sanskrit page for निदानपञ्च and पञ्चक and got zero occurrences. WHO's ITA-4.3.2 gives it as a Sanskrit headword, so it is established usage somewhere. Madhava Nidana's chapter is titled Pañca Nidāna Lakṣaṇa, which is close but not the same compound. Someone should trace the first attestation.
- Whether the third member is liṅga or rūpa. Charaka Ni. 1.6 says liṅga; Ashtanga Hridaya Ni. 1.2 says rūpa; Ca. Ni. 1.9 then declares them synonymous. The modern name of the member follows Vagbhata, not Charaka.
- Whether anupaśaya is a sixth member or the negative half of the fourth. Sources split, and Madhava Nidana chapter 1 treats the pair together at 1.8-9 while the set is still called five.
- The Devanagari निदानपञ्चक is given here from the WHO index entry, whose Devanagari column extracted with damaged glyphs from the PDF. I did not sight clean Devanagari for the compound in a Sanskrit source.
