Ayurveda is the science of life or longevity, which helps in the promotion of health, prevention of diseases and in achieving a long life. The basic philosophy of Ayurveda is based on the panchamahabhoota (five elements) theory. This theory states that the universe as well as the human body is made up of five elements, namely air (vayu), space (akash), earth (prithvi), fire (agni) and water (jal). These elements combine to form controlling forces or biological humours called Dosha. These dosha are responsible for sustaining the living body in its normal state and are of 3 types: Vaata, Pitta and Kapha.
These controlling forces or the doshas act on the tissues of the body known as the Datus and help in the various physiological functions. The waste products formed as a result of various bodily functions are Malas, which are end products of the body. Thus the science of Ayurveda deals with Doshas, Dhaatus & Malas.
It is responsible for active movements of different organs and parts of our body.
