Kashyapa Samhita, Sutrasthana 1.3
Kumaro hi sukumaro — The child is supremely delicate. Its treatment requires the most refined knowledge because the doses, preparations, and methods appropriate for adults are never appropriate for children. Kaumarabhritya is the science of this refinement.

The Kashyapa Samhita

The Kashyapa Samhita (also known as Vriddha Jivakiya Tantra) is the classical text dedicated exclusively to Kaumarabhritya — compiled by Kashyapa, one of the sages of the Atreya school. The text documents the complete continuum from preconception practices through childhood. It is the oldest dedicated paediatric medical text in the world. Key sections: Sutrasthana (foundational principles), Nidanasthana (disease causes in children), Chikitsasthana (treatments), and the Jivaka sections on neonatal and infant care.

Prasuti Tantra — obstetric principles

Classical documentation covers: Garbha Dharana (conception — factors determining successful conception including Beeja quality and Kshetra quality); Garbhini Paricharya (pregnancy care — month-by-month protocol, full documentation on the Garbhini Paricharya page); Prasava (delivery — stages, positions, natural management, intervention indicators); and Sutika Paricharya (post-natal care — the 45-day post-delivery recovery protocol).

Jatakarma — neonatal practices

Classical neonatal practices documented in Kashyapa Samhita and Charaka Samhita: Jatakarma (first neonatal ceremony): a drop of gold-honey-ghee mixture placed on the tongue immediately after birth — classical intent: providing minerals (gold) and antimicrobial (honey) support to the newborn's first oral contact. Nishkramana (first exposure to sunlight — on day 12): the classical practice of brief morning sunlight exposure for the neonate, now confirmed as beneficial for neonatal jaundice through phototherapy mechanisms. Annaprasana (first solid food — month 6): the classical timing for introducing semi-solid food — consistent with modern WHO guidelines for exclusive breastfeeding to 6 months.

Stanya — classical lactation documentation

Charaka Samhita documents extensive Stanya (breast milk) guidelines: Samyak Stanya (ideal breast milk) signs — white, no froth, dissolves in water without residue, adequate flow. Stanya Dushti (impure breast milk) signs by Dosha — Vataja Stanya Dushti produces colic in the infant; Pittaja produces fever; Kaphaja produces respiratory congestion. The classical treatment of impure breast milk through treating the mother's Dosha imbalance (rather than stopping breastfeeding) is the classical equivalent of modern lactation medicine's understanding that breastfeeding issues usually require treating the mother, not stopping feeding.

Dose adjustment for children
Kashyapa Samhita documents the Kumara Matra (child dose) calculation: doses are adjusted by body weight and age relative to adult norms. Classical formula: the dose for a child is proportional to its Shareera Bala (physical strength) relative to an adult — not a simple fraction. This is the classical recognition that paediatric pharmacokinetics differs from adult pharmacokinetics — the same principle underlying modern paediatric medicine's weight-based dosing protocols. Herb preparations for children also differ: powders suspended in milk or honey; decoctions at lower concentrations; avoidance of heating herbs (Ushna Virya) that can aggravate children's already-elevated Pitta.
