In Sanskrit, 'Kati' means the lower back and 'Basti' means retaining something inside. Kati Basti is a soothing treatment where a large quantity of warm herbalised oil is retained on your lower back to relieve pain, stiffness and inflammation.
Stroking and caressing serve not only to show affection but help relieve pain as well. This feature of behaviour is found in animals too. The cow licking its calf is an expression of love. Equally, by the process of gently caressing, veins and arteries can be rejuvenated, and thereby pain lessened. An awareness of this physiological peculiarity was what caused the evolution of Uzhichil as a scientifically developed treatment procedure. Charaka, Sushruta and Vagbhata emphasize the importance of Uzhichil and Pizhichil. Oil massage is known to improve blood circulation. Uzhichil is also helpful in removing oedema in various cells, reducing obesity and improving digestion.
Thaila lepanam is the application of oil all over the body before the student begins the exercise regimen, and this is an integral part of Kalaripayattu training. Sesame oil is generally used for the purpose. Occasionally, however, certain other oils that are more conducive to the physical peculiarity of the student are also chosen. Application of oil imparts flexibility to the body, reduces obesity and gives strength to the muscles. Usually, the students do the oil application on their own. Kalari massage helps the body to attain flexibility and liveliness. This enables proper blood flow and easy movements of the body for distorting. Massage relieves pains, stiffness, dislocations, injuries etc. Kalari has come a long way since it was in force for the betterment of human being.
