Ashtakatvara Taila is a classical Ayurvedic medicated oil indicated mainly in Urustambha and Vatika disorders, described in Charaka Samhita and Bhavaprakasha with variations in pharmaceutical proportions. The present study aimed to comparatively evaluate the pharmaceutical preparation of Ashtakatvara Taila as per two classical references and to develop its modified dosage form as a liniment. Two batches of Taila were prepared using Sarshapa Taila as the base, Shunti and Pippalimoola as Kalka Dravya, and Dadhi and Katvara as Drava Dravya, following standard Taila Paka procedures Charaka Samhita ( Batch A) and Bhavaprakasha (Batch B). The prepared Taila was further modified into a liniment by incorporating menthol, camphor, and eucalyptus oil. Detailed observations on temperature, duration, Sneha Siddhi Lakshanas, yield, and loss were recorded. Batch A showed a higher percentage loss of Taila compared to Batch B, whereas both liniment preparations demonstrated improved spreadability, reduced viscosity, cooling sensation, and better skin absorption. The study highlights the influence of classical proportions on pharmaceutical outcomes and supports the utility of liniment as a patient-friendly external dosage form of Ashtakatvara Taila.
