Charaka Samhita, Sharirasthana 8.32
Masanumasam garbhini paricharya — The care of the pregnant woman should be adjusted month by month. What is appropriate in the first month is not appropriate in the ninth month. Each stage of the Garbha's (foetus's) development requires different nutritional support from the mother's Dhatu.

Month-by-month protocol

Month 1

Conception to first month

Sashticashali rice with milk and ghee. Light, cool, sweet foods. Avoid pungent, sour, and heavy foods. The embryo at this stage is described as Kalala — liquid essence. Milk is the specific Pathya food for this stage as it nourishes Rasa Dhatu — the first tissue the embryo develops.

Month 2

Sweet, cool preparations

Milk preparations continue. Sweet fruits — grapes, dates. The embryo develops solid form (Ghana). Beginning of cardiovascular development corresponds with emphasis on Rasavaha Srotas nourishment.

Month 3

Three-flavour diet

Sweet, sour, and salty tastes introduced. Milk with honey and ghee. Shashti rice. The classical recognition that the embryo now begins to experience sensations (Iccha — desire) — the mother's cravings (Dauhridya) should be carefully observed and satisfied, as suppressing them is documented as harming the developing child.

Month 4 — 5

Nourishing strengthening foods

Butter and milk in abundance. The foetus develops strength (Bala) — milk and ghee support this. The mother's Hridaya (heart-seat of consciousness) begins to be shared with the foetus.

Month 6

Ghrita-dominant nutrition

Ghee preparations increase. Shatavari Ghrita or plain cow ghee with milk. The foetus's intellect (Buddhi) begins to develop — the classical emphasis on ghee at this stage corresponds with modern understanding of essential fatty acids in neurological development.

Month 7

Brimhana — tissue building

Maximum nourishing foods. Meat soups (where applicable), milk, ghee, sweet preparations. The foetus is now essentially complete — this is the primary Brimhana (tissue-building) month.

Month 8

Yavagu — thin gruel diet

Transition to lighter foods. Yavagu (thin rice gruel) with ghee. Classical reason: Ojas moves between mother and foetus in this month — disturbing it with heavy food can harm both. This corresponds with the physiological third-trimester transfer of maternal immunity to the foetus.

Month 9

Preparation for delivery

Medicated ghee preparations supporting Apana Vata (downward movement force for delivery). Dashamooladi ghee. The diet returns to normal nourishing food. Basti (medicated enema) specifically documented for the ninth month to prepare the birth channels.
