AYURVEDA AND MODERN VIEW ON PHYSIOLOGY OF DIGESTION W.S.R. TO DESCRIPTION OF CONCEPT OF AVASTHA PAK
Abstract
The medical science described digestion as the process in which breakdown of complex food take places into simplest form with the help of enzymatic process. These all phenomena occur in gastrointestinal tract. Ayurveda described role of Jathragni, Dhatwagni and Bhutagni in the conversion of complex food into its simplest monomers. The Agni play key role in this process thus proper functioning of Agni is prerequisite for the digestive physiology. Grahani or Pakvamashaya is also known as Pittadhara Kala which described as the site of Jathragni. The various elements like Samana vayu, Kledaka kapha and Pachaka pitta helps in the process of digestion. Samana vayu stimulate the Pachakagni for the separation of food, Kledaka kapha softens food materials and Pachaka pitta contributed towards the process of digestion. The digestion starts with the consumption of food and this process completed in three stages namely Avastha paka, these stages of Avastha paka are Madhur avastha paka, Amla avastha paka and Katu avastha paka.
