# śākhā (शाखा) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/shakha/ An Ayurvedic technical term, rendered into English in 7 different ways. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | śākhā | | Devanagari | शाखा | | Also written | bāhya rogamārga, śākhā-gata, śākhāśrita | | Category, as gathered | anatomy-pathology (peripheral compartment) | | Grouped under | Body: tissues, wastes and channels | | Classical citations | 3 | | 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. ### Upper and lower limbs WHO International Standard Terminologies on Ayurveda (2022) · ITA-3.1.23, no description text given · who-ista WHO standardises śākhā ONLY in its gross-anatomical sense. It does not record the CS Sū. 11.48 sense (rakta and the other dhātus plus skin), which is the sense the term carries in pathology. 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. ### Branch of knowledge WHO International Standard Terminologies on Ayurveda (2022) · ITA-1.5.3; description: 'Ayurveda is considered a branch of knowledge because it is derived from other Indian knowledge systems such as the Vedas.' · who-ista A wholly different homonym (śākhā = Vedic recension/branch). Its presence in the same standard alongside ITA-3.1.23 shows WHO treats śākhā as two unrelated words and neither is the pathological one.

Charaka Samhita, tr. Kaviratna — translator's footnote · footnote marked '†' at Sūtrasthāna ch. 11, his verse 47 (OCR renders the two words as 'fdkhd' and 'koshtha') · public-domain-translation A deliberate refusal to translate, in 1900, on the ground that the terms are technical. The strongest single argument in this record against any confident single English equivalent. ### Amongst these, Śākhā includes blood and the like, the humours known by the name of Dhatu, and skin. These constitute the External seat of disease. Charaka Samhita, tr. Kaviratna · Sūtrasthāna ch. 11, his verse 47 (= CS Sū. 11.48); OCR renders Śākhā as '£akha' · public-domain-translation Where he must convey it, he glosses rather than translates. ### 'Cakha' literally means branch. As a technical word in medical science, it implies, as explained in the text, blood and the like, the humours and the skin. Of course, it includes flesh, marrow, fat, bones, and seminal fluid. Charaka Samhita, tr. Kaviratna — translator's footnote · footnote '*' following his verse 49, Sūtrasthāna ch. 11 (OCR: 'Cakha', '9akha') · public-domain-translation Kaviratna reports the commentator's reason (analogy with the branches of a plant) and then adds 'The analogy, however, is not obvious', a translator openly recording that he does not find the etymology convincing. ### periphery / peripheral tissues / external pathway Standard Indian BAMS textbook and journal usage · ubiquitous; e.g. 'shakha (peripheral path)' in the CSRTSDC online edition's gloss on Sū. 11.48 (paraphrased, not quoted — that translation is in copyright) · textbook · our paraphrase of the source, not its words The dominant modern rendering. It captures the rogamārga sense and loses the limb sense; WHO does the reverse. ## The classical passages ### Charaka Samhita Sūtrasthāna 11 (Tistraiṣaṇīya):11.48, checked against the source > तत्र शाखा रक्तादयो धातवस्त्वक् च, स बाह्यो रोगमार्गः tr. none (Sanskrit mūla) · https://www.carakasamhitaonline.com/index.php/Tistraishaniya_Adhyaya The defining statement: śākhā = rakta and the remaining dhātus, plus the skin; and it is the EXTERNAL disease-pathway. Note it is defined by tissue class, not by body region. ### Charaka Samhita Sūtrasthāna 28 (Vividhāśitapītīya):28.31 **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://gretil.sub.uni-goettingen.de/gretil/corpustei/transformations/plaintext/sa_agniveza-carakasaMhitA-parts-comm.txt Five causes by which malas move FROM koṣṭha TO śākhā: exercise, sharpness of heat, non-observance of the wholesome, and the swiftness of vāyu. Establishes śākhā and koṣṭha as a functional pair, not merely two of three sites. ### Charaka Samhita Sūtrasthāna 28 (Vividhāśitapītīya):28.33, checked against the source > vṛddhyā viṣyandanāt pākāt srotomukhaviśodhanāt / śākhā muktvā malāḥ koṣṭhaṃ yānti vāyośca nigrahāt tr. none (Sanskrit mūla) · https://gretil.sub.uni-goettingen.de/gretil/corpustei/transformations/plaintext/sa_agniveza-carakasaMhitA-parts-comm.txt The return movement: by increase, liquefaction, ripening, clearing of the channel-mouths and restraint of vāyu, malas leave śākhā and go to koṣṭha. This is the verse that underwrites the whole of pre-purificatory therapy, and it is why śākhā cannot be translated as 'limbs'. ## Not to be confused with - **śākhā as limb/extremity.** The same word, and the sense WHO ISTA standardises (ITA-3.1.23). In CS Sū. 11.48 it denotes a tissue class (rakta onward plus tvak), which is present throughout the body including the trunk. Using the limb sense in a pathology context makes nonsense of śākhāgata doṣa. - **koṣṭha.** Its paired opposite. Doṣas move between them in both directions (CS Sū. 28.31 and 28.33); a therapy that works on one is chosen precisely because the doṣa is in the other. - **dhātu.** Śākhā in the rogamārga sense is a COLLECTION of dhātus plus skin, considered as a site. A dhātu is a constituent. Saying 'the disease is in rasa dhātu' and 'the disease is in śākhā' are claims at different levels. - **tvak / bahiḥ.** Skin is one member of śākhā, not a synonym for it; bāhya ('external') is the rogamārga's epithet, not the compartment's name. - **śākhā as Vedic recension.** Unrelated homonym, separately standardised by WHO at ITA-1.5.3. Text searches for 'śākhā' will return both. ## Renderings that do not hold - limbs / extremities. Correct for the anatomical homonym, wrong for the rogamārga. CS Sū. 11.48 defines śākhā by tissue (rakta and other dhātus, skin), and disorders Charaka assigns to it include skin lesions and swellings that are not limb-confined. - branch. The literal etymology. Kaviratna reports the commentator's plant analogy and then records that 'The analogy, however, is not obvious', a translated 'branch' conveys nothing clinical. - superficial tissues. Śākhā includes asthi and majjā per Kaviratna's own footnote gloss ('it includes flesh, marrow, fat, bones, and seminal fluid'), so 'superficial' is wrong on its face, though note asthi also figures in the madhyama mārga, which is a real tension in the text. - skin. Tvak is one item in the list, mentioned last and with 'ca'. ## Open questions Recorded rather than resolved. - The apparent overlap: asthi appears within śākhā (as one of 'rakta and the rest of the dhātus') and also within the madhyama rogamārga as asthi-sandhi. How the commentators resolve this was not checked. - Whether any classical text uses śākhā in the rogamārga sense outside Charaka. - Whether WHO ISTA's omission of the pathological sense of śākhā was deliberate. ## Citation Age Ayurveda Nighantu, "śākhā", https://nighantu.ageayurveda.com/lexicon/shakha/, CC BY 4.0.
