dhātu-poṣaṇa: what the term means and how it is translated
dhātu-poṣaṇa धातुपोषण is an Ayurvedic technical term. It is rendered into English in 6 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
the process of nourishment of fundamental structural components
WHO International Standard Terminologies on Ayurveda (2022) · wording inside descriptions of ITA-2.6.19 and ITA-2.6.21; WHO has NO headword for dhātu-poṣaṇa itself · standard
WHO covers the three explanatory theories but gives no umbrella entry for the process. 'Fundamental structural components' is WHO's house rendering of dhātu throughout.
Reproduced unaltered and attributed from the WHO International Standard Terminologies on Ayurveda, which is what that licence permits. It is deliberately absent from the downloadable dataset, which is offered under CC BY 4.0 and invites the modification a NoDerivs licence forbids.

The successive development of the fundamental or root principles of the body
Sushruta Samhita tr. Kaviraj Kunja Lal Bhishagratna (1907) · Sūtrasthāna ch. 14, translator's footnote · translation
Public domain. Bhishagratna has no single term; he describes the process. 'Root principles' is his standing rendering of dhātu.
That food nourishes the body, the 'dhatus,' the 'ojas,' the strength, the complexion, &c., is due to fire as the operating cause
Charaka Samhita tr. Avinash Chandra Kaviratna (1896-1913) · Cikitsāsthāna 15, Kaviratna's v.4 · translation
Public domain. Kaviratna uses plain 'nourishes'; he coins no technical English term.

The classical passages
Each citation gives its address so a reader can check it in a printed edition, our account of what the passage establishes, and the result of reading it against its source.
Charaka SamhitaCikitsāsthāna 15 (Grahaṇī-doṣa-cikitsā):Kaviratna's v.15 · checked against the source
From 'Rasa' (juice) arises blood ; from blood is flesh ; from flesh is adeps ; from adeps is bone ; from bone is marrow ; from marrow is vital seed : from the vital seed arises the fcetus.
The mūla text states only the ORDER of derivation of the seven dhātus, not a mechanism. All three nyāyas are commentarial attempts to supply the missing mechanism.
Charaka SamhitaCikitsāsthāna 15:Kaviratna's v.20 · checked against the source
Some are of opinion that the transformation (of one 'dhatu' into another) takes place in six days and nights. Of food and the 'dhatus' this transformation goes on eternally like (the motion of) a wheel.
The mūla itself reports the six-day transformation period as an opinion ('some are of opinion'), i.e. the text does not settle the timing question either.
Sushruta SamhitaSūtrasthāna 14:not numbered in Bhishagratna · checked against the source
The chyle produces blood. From blood is formed flesh. From flesh originates fat which gives rise to bones. From bones originate marrow, which, in its turn, germinates semen.
Sushruta gives the same succession independently of Charaka. Secondary sources cite this as Su.Sū.14/10; Bhishagratna's text carries no verse numbers, so the verse number is not verified here.
Charaka Samhita with Cakrapāṇidatta's ĀyurvedadīpikāSūtrasthāna 28 (Vividhāśitapītīya):commentary on v.4, Cakrapāṇi's segment 21 · checked against the source
anye tv āhuḥ khalekapotanyāyenāyam annarasaḥ pṛthak pṛthag dhātumārge gataḥ san rasādīn poṣayati na tv asya dhātupoṣako rasabhāgo dhātvantareṇa samaṃ sambandham apyanubhavati
Cakrapāṇi's commentary on Ca.Sū.28.4 is the primary locus where the competing nourishment models are set out and weighed. This is the anchor citation for the whole dhātu-poṣaṇa topic.
Not to be confused with
- dhātu-pariṇāma
- Pariṇāma is transformation of one dhātu into the next, which is only ONE of the competing accounts of poṣaṇa. Treating them as synonyms silently commits the entry to the kṣīra-dadhi model that Cakrapāṇi rejects.
- dhātu-agni
- Dhātvagni is the transforming agency; poṣaṇa is the process and its result. The nyāyas are about routing and selection of nutrient, not about the fire that acts on it.
- dhātu-sāra
- Sāra is the qualitative excellence of a fully-nourished dhātu, used in constitutional assessment. Poṣaṇa is the supply process.
- poṣaka vs sthāyi dhātu
- The nutrient fraction in transit (poṣaka) versus the settled tissue (sthāyi). Cakrapāṇi's argument turns entirely on this distinction; collapsing it makes the khale-kapota position incoherent.
- upadhātu
- Secondary tissues produced as by-products of the main sequence, not stages in it.
Renderings that do not hold
- tissue metabolism. Metabolism covers catabolism and energy turnover; poṣaṇa is specifically the supply-and-incorporation side, and the classical debate is about routing, not about chemical turnover.
- anabolism. Imports a biochemical category that the classical accounts do not make. None of the three nyāyas is about synthesis reactions.
- tissue perfusion. Correct only for the kedārī-kulyā model and wrong for khale-kapota, which is explicitly about selection rather than delivery.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Whether dhātu-poṣaṇa occurs as a fixed compound in any mūla text, or is a modern textbook headword for a topic the texts discuss without naming. Nothing retrieved settles this.
- The fourth model, ekakāla dhātu poṣaṇa (simultaneous nourishment), is named only in PMID 32855015 among sources retrieved here. Its classical locus was not established.
- Kaviratna's verse numbers in Cikitsāsthāna 15 run one behind the numbering used by Chakrapani-based editions (his v.15 = the verse everyone cites as Ci.15/16). This offset needs confirming across the whole chapter before any Kaviratna verse number is published.
