# dhātu-sāra (धातुसार) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/dhatu-sara/ An Ayurvedic technical term, rendered into English in 8 different ways. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | dhātu-sāra | | Devanagari | धातुसार | | Also written | sara, sāra, dhatu sara, sara pariksha, ashta sara, saramsha | | Category, as gathered | dhatu | | Grouped under | Body: tissues, wastes and channels | | Classical citations | 6 | | Citations checked | 2026-10-08 | ## How it is translated, and whether the translation holds Each rendering is given with the source that uses it. The assessment is ours. ### Predominance of a particular fundamental structural component in a person WHO International Standard Terminologies on Ayurveda · ITA-2.8.1.1 (Sanskrit: sāraḥ). Section heading 2.8.1 reads 'Predominance of a specific fundamental structural component' · standard WHO's headword is for sāraḥ alone; there is no ISTA entry for the compound dhātusāra. Note WHO's entry carries no description text at all, only the headword - unusual in the volume and possibly an omission.

Charaka's list as Kaviratna renders it begins with skin, not rasa. WHO has silently resolved a classical variant. Reproduced unaltered and attributed from the WHO International Standard Terminologies on Ayurveda, which is what that licence permits, and deliberately absent from the downloadable dataset, which is CC BY 4.0. ### Person with predominance or essence of blood / muscle / fat / bone / bone marrow / semen / strong willpower / all seven WHO International Standard Terminologies on Ayurveda · ITA-2.8.1.3 to ITA-2.8.1.10 (rakta-, māṃsa-, medo-, asthi-, majja-, śukra-, sattva-, sarva-/oja-sāraḥ) · standard Eight further entries, one per sāra, each with a description close to Charaka Vimanasthana 8. ITA-2.8.1.10 gives sarva-sāraḥ and oja-sāraḥ as synonyms for the all-seven type.

Avinash Chandra Kaviratna (1896-1913) · Vimanasthana VIII · translation His running rendering, which he himself complains about in a footnote as 'this long periphrasis'. ### pith Charaka Samhita, tr. Avinash Chandra Kaviratna (1896-1913), translator's note · Footnote to Vimanasthana VIII · translation Kaviratna's proposed short form, so that twak-sāra becomes 'Skin-pithed'. Idiosyncratic, but it is the only place in the public-domain corpus where a translator reasons openly about how to render this term, which makes it valuable rather than merely quaint. ### quintessence Sushruta Samhita, tr. Kunja Lal Bhishagratna (1907-1916) · Sutrasthana XV, of ojas as the sāra of all the dhātus · translation Bhishagratna uses 'quintessence' where Sushruta makes ojas the sāra of all seven. Sushruta's sāra examination is a separate passage, at Sutrasthana 35. ### Sara (predominance of fundamental structural components) Modern Ayurvedic journal usage · PMID 42161239, methods section · journal The journal literature has adopted WHO's phrasing more or less verbatim. Worth recording as evidence of ISTA's influence on usage. ### tissue excellence / tissue quality Common modern Ayurvedic teaching · textbook · our paraphrase of the source, not its words Widespread. Introduces a quality judgement ('excellence') that the WHO and Kaviratna renderings do not, though Charaka's descriptions are indeed uniformly favourable. ## The classical passages ### Charaka Samhita Vimanasthana 8 (the Vimana of how disease is to be conquered by the physician; Rogabhishagjitiya):102, checked against the source > Next, as to examination according to Sara (predominating essence or element) : there are eight Saras of human beings. We shall lay down instructions about them for exact knowledge of the measure of one's strength. They are i. skin, 2. blood, 3. flesh, 4. fat, 5. bones, 6. marrow, 7. vital seed, and 8. mind, tr. Avinash Chandra Kaviratna (1896-1913) · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt The eightfold enumeration, with SKIN (tvak) first, not rasa, and MIND (sattva) eighth. Also the stated purpose: sāra examination measures strength (bala), not tissue quality in the abstract. Chapter located by the heading 'We shall next expound the Vimanam called how disease is to be conquered by the physician' in the retrieved file. ### Charaka Samhita Vimanasthana 8:translator's footnote, checked against the source > It will be seen that the word "sara" has been rendered "predominance of (constituting) element." This long periphrasis becomes inconvenient in rendering such short compounds as 'Twak-sara', 'Rakta-sara,' &c. The fact is, if 'sara' be baken as equivalent to 'pith' in the sense of 'essence,' the periphrasis may be abandoned with this explanation. 'Twak-sara' may be rendered as 'Skin-pithed ;' so 'Rakta-sara' as 'Blood-pithed,' &c. Hence 'Asara' implying the absence of 'Sara,' may be rendered as 'having no pith' tr. Avinash Chandra Kaviratna (1896-1913), translator's footnote · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt A translator reasoning explicitly about how to render sāra, and coining 'pith'. Also attests the compound forms twak-sāra and rakta-sāra, and the negative asāra. OCR has 'baken' for 'taken'. ### Charaka Samhita Vimanasthana 8:125 in Kaviratna's marginal numbering, checked against the source > Now, those men in whose constitutions all the elements exist in a large and harmonious measure, become endued with great strength and great honors (in every direction). They become capable of enduring toil and pain in all kinds of acts : they are inspired with confidence in their own abilities tr. Avinash Chandra Kaviratna (1896-1913) · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt Sarva-sāra, the all-round type, which WHO records at ITA-2.8.1.10 with oja-sāraḥ as a synonym. ### Charaka Samhita Vimanasthana 8:126-128 in Kaviratna's marginal numbering, checked against the source > Those men that are possessed of attributes which are the reverse of these, are regarded as possessed of no pith. Persons endued with a predominance, in a middling measure, of any of the eight elements, have attributes, corresponding with the above, in a middling measure. Thus have been explained the eight different kinds of pith as regards human beings. These explanations are given for a knowledge of the differences in respect of the measure of strength of different men. tr. Avinash Chandra Kaviratna (1896-1913) · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt That sāra is graded (pravara, madhyama, avara) rather than binary, that asāra is a recognised category, and again that the purpose is assessing strength. ### Charaka Samhita Vimanasthana 8:129 in Kaviratna's marginal numbering, checked against the source > It has been said that a person should be examined by the test of his pith. This has been laid down for preventing a physician from arriving at an erroneous conclusion by a sight of the body alone of the patient. Such conclusions should never be formed, viz., that this one is endued with strength because this one's body is large ; ... It is, indeed, seen that men whose bodies are of small dimensions or whose bodies are lean are still possessed of strength. In this connection, a proof is offered by ants (which are very diminutive creatures) btearing away large weights. tr. Avinash Chandra Kaviratna (1896-1913) · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt The stated RATIONALE for sāra examination: body size is an unreliable index of strength, so a different measure is needed. This is the text arguing for its own method, and it is the passage a lexicon entry should be built around. OCR has 'btearing' for 'bearing'. ### Sushruta Samhita Sutrasthana 15:19 (Bhishagratna, Chap. XV, p. 130), corrected against the source > The quintessence of all the fundamental principles of the body, starting with lymph chyle and ending with semen, is called the Ojas, which is identical with what is termed "vital power." tr. Kunja Lal Bhishagratna (1907-1916) · https://archive.org/stream/b24758619_0001/b24758619_0001_djvu.txt Sushruta's use of sāra for ojas, the essence of all seven dhātus. This is separate from Sushruta's sāra examination, which comes at Sutrasthana 35, where Bhishagratna translates the traits of each preponderant principle (Sara). ## Not to be confused with - **prakṛti.** Constitution by doṣa predominance, determined at conception and fixed. Sāra is predominance by dhātu and is assessed at examination. PMID 42161239 records both separately for each participant, which is the clearest demonstration that they are different instruments. - **bala.** Strength, which sāra examination exists to estimate. Charaka Vimanasthana 8 states the purpose explicitly. WHO gives balam its own headword at ITA-2.2.27. Sāra is the index; bala is what is indexed. - **dhātu-sāmya.** Equilibrium of the dhātus (WHO ITA-2.2.26), a state of health. Sāra is a constitutional predominance, present in health. A person can be dhātu-sāmya and also asthi-sāra. - **ojas.** WHO gives oja-sāraḥ as a synonym of sarva-sāraḥ (ITA-2.8.1.10), and Sushruta calls ojas the quintessence of all dhātus. So ojas is both the all-round sāra type and the substance that is the sāra of every dhātu. Two related but distinct uses. - **asthi-sāra.** Collides inside WHO ISTA: at ITA-2.2.16 asthisāram is a Sanskrit synonym for majjā ('bone marrow'), at ITA-2.8.1.6 asthi-sāraḥ is the bone-predominant constitution. Same string, two referents, one standard. - **sāra (other senses).** In dravyaguna sāra is the heartwood of a tree; in general Sanskrit it is essence, pith or wealth. Kaviratna's 'pith' rendering deliberately exploits this. - **sattva-sāra.** The eighth sāra is mind, not a dhātu at all (WHO ITA-2.8.1.9, 'Person with predominance or essence of strong willpower'). So the 'eight saras' are not eight dhātus, and calling the construct dhātu-sāra is already slightly inaccurate. ## Renderings that do not hold - tissue excellence / tissue quality. Introduces a quality judgement. Charaka's construct is predominance for the purpose of estimating strength, and it includes a negative category (asāra, 'having no pith') and a middling grade. 'Excellence' cannot accommodate the grading. - essence. Too bare. It loses the constitutional and diagnostic function entirely, and collides with the separate use of sāra for ojas as the essence of all dhātus. - dhātu-sāra as though it were the classical term. Charaka's phrase as translated is simply sāra, and the compounds attested in Kaviratna's footnote are twak-sāra, rakta-sāra and so on, not dhātu-sāra. WHO ISTA likewise has sāraḥ, not dhātusāra. Citing 'dhātusāra' to Ca.Vi.8 would attribute a compound to the text that the retrieved sources do not show there. - 'the eight dhatu saras'. The eighth is sattva (mind), which is not a dhātu. Charaka's list is skin, blood, flesh, fat, bones, marrow, vital seed and mind. - treating rasa-sāra and tvak-sāra as one type because WHO does. WHO merges them at ITA-2.8.1.2. Kaviratna's Charaka lists skin first and never mentions rasa in the eightfold list. The variant is real and WHO has resolved it in one direction without marking that it did. ## Open questions Recorded rather than resolved. - The tvak-sāra / rasa-sāra variant is unresolved. WHO ISTA merges them under one term ID titled by rasa; Kaviratna's Charaka lists skin. Which the mula gives, and whether commentators differ, needs a Sanskrit Charaka and Chakrapanidatta. - Kaviratna's marginal verse numbers in this section run 116-128 while carakasamhitaonline cites the sāra section as Vi 8/102 ff. Roughly a fourteen-verse offset in this chapter alone. No verse number in this record should be treated as verified. - No study reports interrater reliability for sāra assessment. Given that the project's own reconnaissance records kappa of 0.28 for prakriti assessment, the prior for sāra is poor and nobody has measured it. - Whether sāra classification predicts anything independent of body habitus has not been tested. Charaka's own argument is that it should, since he explicitly rejects body size as an index of strength - which makes it a testable claim that has never been tested. - Sushruta's sāra examination (Sutrasthana 35) has not been compared item by item with Charaka's eightfold list. ## Citation Age Ayurveda Nighantu, "dhātu-sāra", https://nighantu.ageayurveda.com/lexicon/dhatu-sara/, CC BY 4.0.
