Abstract: A modified and efficient single-step process for the production of standardized pudina arka as medicated water from plant Mentha herbs with ratio of drug component in arka to total arka ranging between 1:2 to 1:20 involving complete recovery of all the active material, said method comprising steps of taking aerial parts of the plant Mentha herb, crushing it optionally, adding solvent to the plant parts in the ratio ranging between 6:1 to 25:1 to obtain mixture, macerating the mixture at an elevated temperature, while maintaining desired pH, and pressure conditions, distillating the macerated mixture continuously till requisite amount of distillate is obtained, and obtaining distillate as standard pudina arka.
