उदकद्रोणं तण्डुलानामर्धाढकं त्रयः प्रस्थाः किण्वस्येति मेदकयोगः ॥ कZ_०२.२५.१७ ॥
udakadroṇaṃ taṇḍulānām ardha-āḍhakaṃ trayaḥ prasthāḥ kiṇvasyeti medakayogaḥ
The formulation for medaka is: one droṇa of water, a half-āḍhaka of rice, and three prasthas of ferment (kiṇva).
Standard ratios enable inspection, deter dilution/adulteration, and support predictable excise assessment tied to input-output expectations.
