Five bhutagnis work on the formation of anatomical structure of the body from respective panchamahabhuta in the form of micro channels, by digesting needful components present in biofluid. Now second and third phase of digestion process occur simultaneously in the srotas (microchannels). Waste products are excreted out by apana vayu through urine, feces and sweat. Useful products get absorbed by rasayani (villi) of the intestine, sent to the micro channels ( srotas) by vyanvata, simutaneouly, to the entire body. Samana vata analyzes and separates the useful products ( prasada) and waste ( kitta). This biofluid is separated into excretable waste or impure products by samana vata in grahani (middle part of GI Tract) and useful, pure circulable products. This nutrient fluid is further trifurcated into three biological substances kapha, pitta and vata in three stages to madhura, amla and katu awastha paka respectively. Jatharagni initiates the first phase of digestion process by conversion of food into nutrient fluid ( ahara rasa). Seven dhatvagnis create seven tissues elements( dhatu). Five bhutagnis transform the panchmahabhauika components of ahara rasa created by jatharagni into different structures of the body. First, the jatharagni is most important because it is the initiator of digestive process and it strengthens the digestive ability of other twelve agnis. These disorders are called grahanidosha.Īgni (digestive and metabolic agents), based on their specific functions of conversion of food into biological elements of the body are classified into thirteen types. The second part describes the abnormal digestion and third part is about diseases caused by abnormality of digestive factors and its interaction with proximal intestine or grahani.
