Sneha means oil. Snehana is the term used in ayurveda
for oleation or the application of oil. Oil may be administered either internally or externally. Saturation of the body with oils either way loosens up the glutinous Amam that has accumulated in the Dhatus / tissues. Vegetable oils, ghee (clarified butter), animal fats and fat from bone marrow are the substances used for oleation. Ghee and sesame oil to which various herbs have been added are commonly used. Animal fats (Vasa) and fat from bone marrow (Majja) are used for certain diseases.
