Ayurvedic Perspective of Snehana Karma: Internal and External Oleation Therapy

Abstract

Snehana refers to oleation therapy, primarily administered prior to Śodhana procedures. It is recommended not only as a preparatory measure for Pañcakarma but also for maintaining general health in daily life. The effectiveness of purification therapy depends on the proper mobilization of Doṣas from the peripheral tissues toward the gastrointestinal tract (Koṣṭha), a process facilitated by Snehana and Svedana. Oleation therapy helps loosen morbid Doṣas and liquefy accumulated toxins, enabling their easy elimination during subsequent Śodhana procedures. Thus, Snehana prepares the body to receive the main purification therapies of Pañcakarma. Snehana is mainly performed using medicated oils and ghee processed with appropriate herbs. It aids in loosening Āma and facilitates its expulsion during purification therapy. Oleation is of two types— internal (Abhyantara Snehana) and external (Bāhya Snehana), both of which play a crucial role in the successful outcome of Śodhana Karma. External oleation involves massage with medicated oils, especially over affected areas, helping to channelize toxins and direct them toward the elimination pathways. Śodhana Karma is invariably preceded by Snehana Karma, which is usually administered gradually over three to seven days or until proper signs of oleation appear. Oleation contributes to bringing the Doṣas into Koṣṭha and inducing Utkleśa, which is essential for effective purification. Detailed descriptions and principles of Snehana Karma have been extensively elaborated by Acharya Charaka.
