The foodcarrying Srotas (Æsophagus)
Kaviraj Kunja Lal Bhishagratna, Sushruta Samhita (1911) · Śārīrasthāna IX.11–12 · public-domain translation
Bhishagratna narrows the channel to the oesophagus and glosses the 'food-carrying Dhamanis' as intestines.

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.
Caraka SaṃhitāVimāna Sthāna 5:5/8 · checked against the source
अन्नवहानां स्रोतसामामाशयो मूलं वामं च पार्श्वं, प्रदुष्टानां तु खल्वेषामिदं विशेषविज्ञानं भवति;तद्यथा- अनन्नाभिलषणमरोचकविपाकौ छर्दिं च दृष्ट्वाऽन्नवहान्यस्य स्रोतांसि प्रदुष्टानीति विद्यात्|
Caraka's root = āmāśaya (stomach) and the LEFT side (vāmaṃ pārśvaṃ); vitiation signs = disinclination for food, anorexia, indigestion, vomiting.
Caraka SaṃhitāVimāna Sthāna 5:5/12 · checked against the source
अतिमात्रस्य चाकाले चाहितस्य च भोजनात्| अन्नवाहीनि दुष्यन्ति वैगुण्यात् पावकस्य च||१२||
Causes of vitiation: excessive, untimely and unwholesome eating, and impaired agni.
Suśruta SaṃhitāŚārīra Sthāna 9:11–12 (Bhishagratna); cited as 9/12 elsewhere · checked against the source
The foodcarrying Srotas (Æsophagus) have their roots in the Amashaya (stomach) and in the food-carrying Dhamanis (intestines). An injury to or piercing of such a duct (Srota), gives rise to tympanites, colic pain, aversion to food, vomiting, thirst, blindness or darkness of vision, or may even end in death.
Suśruta's root = stomach + food-carrying dhamanīs. Agrees with Caraka on āmāśaya but replaces Caraka's 'left side' with the dhamanīs.
Not to be confused with
- mahāsrotas
- WHO defines mahāsrotas (ITA.3.11.1) as 'The major inner cavity of the body from the mouth to anus', which overlaps annavaha srotas almost entirely but is a cavity term, not a transport-channel term; Caraka uses mahāsrotas as a root of prāṇavaha, not annavaha.
- āmāśaya / pakvāśaya
- These are organs (receptacles) named as roots; annavaha srotas is the conduit system rooted in them.
- purīṣavaha srotas
- Both are gut-located, but Caraka roots purīṣavaha in pakvāśaya + sthūlaguda, i.e. the distal gut, and assigns it excretory rather than alimentary function.
- rasavaha srotas
- The product of annavaha srotas' work (āhāra rasa) enters rasavaha srotas; texts and modern authors slide between them when discussing 'nutrition'.
Renderings that do not hold
- oesophagus. Bhishagratna's parenthetical. The Sanskrit names no oesophagus; both Caraka and Suśruta root the channel in the stomach.
- the digestive system (as a whole, including liver/pancreas). Common textbook expansion. Caraka's named roots are stomach and the left flank only; liver and spleen belong to raktavaha srotas in the same passage.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Does 'vāmaṃ pārśvam' refer to the spleen, the left hypochondrium, or the greater curvature of the stomach?
- Is there any classical warrant for including hepatobiliary/pancreatic structures in annavaha srotas, or is that purely a modern biomedical mapping?
