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

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

### Colouring pitta

WHO international standard terminologies on Ayurveda (2022), term ID ITA-2.1.2.3 · ITA-2.1.2.3; printed p. 35 (PDF p. 53). Sanskrit term 'rañjaka-pittam'. Description: 'Subtype of pitta seated in liver, spleen and its pigment in blood.' · standards-body

WHO's description is grammatically broken as printed ('seated in liver, spleen and its pigment in blood'), worth flagging to anyone quoting it. Substantively WHO follows SUŚRUTA's seat (liver and spleen), not Vāgbhaṭa's (āmāśaya). That is a silent editorial choice between two disagreeing classical authorities.

### Ranjakagni (lit:—dyeing fire or pigment bile.)

Suśruta Saṃhitā tr. Kaviraj Kunja Lal Bhishagratna (public domain) · Sūtrasthāna ch. 21, Wikisource text · public-domain-translation

Bhishagratna's 'pigment bile' is a 19th-century humoral-medicine gloss reflecting the then-current identification of pitta with bile. 'Dyeing fire' is the literal rendering of rañjaka + agni.

### Ranjaka

Suśruta Saṃhitā tr. Bhishagratna, footnote at Sūtrasthāna ch. 15 · 'They are named as Ranjaka. Pachaka, Sadhaka (Medhakrit and Ojakrit), Alochaka and Bhrajaka.' · public-domain-translation

Bhishagratna lists rañjaka FIRST, matching the order of functions at Su.Sū. 15.4 (rāga-kṛt first), not the order of Su.Sū. 21.10 (pācaka first).

### bestows red color to Rasa Dhatu and converts it into blood

EasyAyurveda, Suśruta Sūtrasthāna 21 study page · Commentary under Su.Sū. 21.10 · modern-textbook-website

Adds 'and converts it into blood', which the Suśruta mūla does not say, the mūla says only 'sa rasasya rāgakṛd uktaḥ' (it imparts colour to rasa). The conversion claim is Vāgbhaṭa-influenced interpretation.

## The classical passages

### Suśruta Saṃhitā Sūtrasthāna 21 (Vraṇapraśna Adhyāya), checked against the source

> The Ranjakagni:—The function of the Pittam, which has its seats in the liver and the spleen, consists in imparting its characteristic pigment (Ragakrit) to the lymph-chyle and is hence known as Ranjakagni (lit:—dyeing fire or pigment bile.)

tr. Kaviraj Kunja Lal Bhishagratna · https://en.wikisource.org/wiki/Sushruta_Samhita,_Volume_1/Chapter_21

Seat = liver and spleen; function = imparting colour to rasa; designation = rañjakāgni.

### Suśruta Saṃhitā (Sanskrit mūla) Sūtrasthāna 21:10, checked against the source

> यत्तु यकृत्प्लीह्नोः पित्तं तस्मिन् रञ्जकोऽग्निरिति सञ्ज्ञा, स रसस्य रागकृदुक्तः;

Sanskrit mūla · https://www.easyayurveda.com/sushruta-samhita-sutrasthana-21-vranaprashna-adhyaya-question-concerning-wounds/

Seat is yakṛt-plīhan (liver and spleen). The mūla's function clause is narrow: 'sa rasasya rāgakṛd uktaḥ', it is said to be the colour-maker of rasa. Nothing about converting rasa into rakta.

### Aṣṭāṅga Hṛdaya (Sanskrit mūla; no public-domain English translation exists, so no translation is quoted) Sūtrasthāna 12 (Doṣabhedīya):13a (following ||१२||)

**Quotation withheld:** nobody has yet read this quotation against its printed source, and an unchecked quotation is not published here. The passage is at https://www.easyayurveda.com/2013/04/16/dosha-types-increase-and-decrease/

THE KEY CLASSICAL DISAGREEMENT: Vāgbhaṭa seats rañjaka in the ĀMĀŚAYA (stomach), directly contradicting Suśruta's yakṛt-plīhan (liver and spleen). Same name, same function (rasa-rañjana), different organ. Corroborated: PMID 40972327 cites 'Ashtanga Hridaya, Sutra Sthana 12/13' for 'Ranjaka Pitta does Rasa Ranjana'.

## Not to be confused with

- **rakta dhātu.** Rañjaka acts ON rasa to colour it; it is not blood and not the blood tissue. English texts that render rañjaka pitta as 'the blood-forming pitta' quietly promote it from a colouring agent to a haematopoietic organ.
- **pācaka-pitta (in Vāgbhaṭa's scheme).** Because Vāgbhaṭa puts rañjaka in the āmāśaya, in his scheme rañjaka and pācaka are near-neighbours in the same region, which they are not in Suśruta. Any statement about rañjaka's seat is meaningless without naming which authority is being followed.
- **'rakta-pitta'.** A disease (a bleeding disorder), not a doṣa subtype. The similar shape of the compound causes genuine confusion in search and in indexing.

## Renderings that do not hold

- "haemoglobin" or "the pitta of erythropoiesis". A hypothesis dressed as a definition. The Suśrutan mūla claims only that it colours rasa. Erythropoiesis happens in red marrow, which no classical text assigns to rañjaka. The equation also has to pick a side in the liver/spleen vs stomach disagreement and usually does so without saying so.
- "bile" / "pigment bile". Bhishagratna's own gloss, and historically interesting, but it imports the Galenic identification of pitta with bile. Bile pigments colour faeces, not rasa, so the gloss does not even fit the function it is glossing.
- Citing 'liver and spleen' while citing Aṣṭāṅga Hṛdaya. Extremely common and simply wrong. AH Sū 12.13 reads 'āmāśayāśrayaṃ pittaṃ rañjakam'. The liver/spleen seat is Suśruta's.

## Open questions

Recorded rather than resolved.

- How do the commentators (Dalhaṇa on Suśruta, Aruṇadatta/Hemādri on AH) reconcile the yakṛt-plīhan vs āmāśaya seat? This is the single most important unresolved point in the record.
- WHO ISTA chose the Suśrutan seat. Is that choice documented anywhere in the WHO drafting process, or was it undiscussed?
- Is the WHO description's broken grammar ('seated in liver, spleen and its pigment in blood') an erratum? Check whether a corrected reprint exists.
