An injury to any of these channels is characterised by swelling, loss or atrophy of the muscles, appearance of varicose veins or may (ultimately) result in death. tr. Kaviraj Kunja Lal Bhishagratna (1911) · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-3-sharirasthana/d/doc142889.html Suśruta's roots = snāyu, tvak, plus the blood-carrying dhamanīs. Quoted exactly as printed, including Bhishagratna's garbled glossing; I confirmed the identical wording in the independent archive.org scan of the 1911 edition (https://archive.org/stream/b24758619_0002/b24758619_0002_djvu.txt), so this is the edition's text, not a transcription error by wisdomlib. ## Not to be confused with - **snāyu.** snāyu is the root, and is itself contested: Bhishagratna glosses it 'nerves', WHO and NAMASTE read 'tendons'. It is not the channel. - **medovaha srotas.** māṃsa and medas are consecutive dhātus and their srotas are adjacent in every list; the roots are wholly different (snāyu/tvak vs vṛkka/vapāvahana). - **māṃsa dhātu and māṃsa-dharā kalā.** The tissue and its membrane are separate concepts from the conduit. ## Renderings that do not hold - snāyu = nerves. Bhishagratna's 1911 gloss, printed in the retrieved text as 'the ( Snayu ), nerves'. Both WHO (ITA-2.5.13 'tendons and skin') and NAMASTE read snāyu as tendon/ligament. The 'nerves' reading is a 19th-century artefact. - tvak = serum. The retrieved 1911 text reads 'Tvak (serum)'. tvak is skin. This is an outright error in the public-domain translation and must not be propagated; it is quotable as evidence about Bhishagratna, not usable as a meaning. - the muscular system. The roots named are tendon and skin, not muscle; the channel is defined by what it nourishes, not by where it lies. ## Open questions Recorded rather than resolved. - Does snāyu here mean tendon/ligament (WHO, NAMASTE) or nerve (Bhishagratna, Ḍalhaṇa-influenced readings)? - Is NAMASTE's 'Su.Sa.9/13' a typo or a real edition variant? ## Citation Age Ayurveda Nighantu, "māṃsavaha srotas", https://nighantu.ageayurveda.com/lexicon/mamsavaha-srotas/, CC BY 4.0.
