Herbal infusions have emerged as an important category of functional beverages owing to their nutritional, therapeutic, and consumer appeal. Although Ayurveda provides a comprehensive pharmacodynamic framework for the rational selection and application of medicinal plants, these classical principles are seldom incorporated into the contemporary development of herbal infusions. Existing formulation approaches primarily emphasize phytochemical composition, pharmacological activity, and sensory attributes, with limited consideration of Ayurvedic concepts governing ingredient selection, processing, and therapeutic applicability. This conceptual methodology paper was developed through a narrative synthesis of classical Ayurvedic literature and contemporary scientific evidence. Authoritative Ayurvedic texts, including the Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya, and relevant Nighantus, were reviewed alongside published literature on herbal infusions, functional beverages, sensory evaluation, and botanical product development. The evidence was critically synthesized to identify methodological gaps and formulate a structured framework for herbal infusion development. The literature demonstrated that classical Ayurvedic concepts, particularly Dravya, Rasa, Guna, Virya, Vipaka, Prabhava, Anupana, and Kalpana, provide a robust theoretical basis for formulation design. However, these principles remain inadequately integrated into current herbal beverage research. A comprehensive methodological framework was therefore proposed, encompassing sequential stages of defining the intended health objective, Ayurvedic herb selection, pharmacodynamic evaluation, formulation design, application of Phanta Kalpana, organoleptic optimization, physicochemical characterization, quality assessment, consumer acceptability, and future validation. The framework bridges traditional Ayurvedic pharmaceutics with contemporary product development practices and provides a reproducible approach for developing evidence-informed herbal infusions.
