Internal Applications of Rasna in Classical Ayurvedic Formulations – A Systemic and Srotas-wise Review

Abstract

Rasna, a prominent medicinal herb in Ayurveda, holds significant therapeutic importance, particularly in the management of Vata-related disorders. It is extensively mentioned in classical texts such as the Charaka Saṃhita, Sushruta Saṃhita, and Bhavaprakasha. Rasna is classified under categories like Vayasthapana (rejuvenative) and Anuvasanopaga (adjuvant in oil-based enemas) Mahakashayas. Its diverse pharmacological properties—including Vata-Kapha Shamana (pacifying Vata and Kapha), Ushna Virya (hot potency), and Tikta Rasa (bitter taste)—make it a key ingredient in various Ayurvedic formulations aimed at treating neuromuscular, respiratory, metabolic, gastrointestinal, and psychological disorders. However, there is a noticeable lack of detailed reviews focusing on its internal administration. This article aims to provide an in-depth analysis of the internal use of Rasna as described in various classical Ayurvedic texts.
