Grahaṇīdōṣha chikitsā adhyāya consists of three parts. First part explains the concept of normal digestion process. Second part describes the abnormal digestion and third part is about diseases caused by abnormality of digestive fire and its interaction with proximal intestine or grahani. These disorders are called grahanidosha.   

[[Grahani Chikitsa]] consists of three parts. The first part explains the concept of normal digestion process. The second part describes the abnormal digestion and third part is about diseases caused by abnormality of digestive fire and its interaction with proximal intestine or ''grahani''. These disorders are called ''grahanidosha''.   

Agni (digestive and metabolic agents), based on their specific functions of conversion of food into biological elements of the body are classified into 13 types. First, the jatharagni is most important because it is the initiator of digestive process and it strengthens the digestive abilty of other 12 agnis. Five bhutagnis transform the panchmahabhauic components of ahara rasa created by jatharagni into different structures of the body. Seven dhatuagnis create seven tissues elements(dhatu).

 

''Agni'' (digestive and metabolic agents), based on their specific functions of conversion of food into biological elements of the body are classified into 13 types. First, the jatharagni is most important because it is the initiator of digestive process and it strengthens the digestive abilty of other 12 agnis. Five bhutagnis transform the panchmahabhauic components of ahara rasa created by jatharagni into different structures of the body. Seven dhatuagnis create seven tissues elements(dhatu).

Jatharagni initiates the first phase of digestion process by conversion of food into nutrient fluid (ahar rasa). This nutrient fluid is further trifurcated into three biological substances kapha, pitta and vata in three stages to madhur, amla and katu awastha paka respectively. This biofluid is separated into excretable waste or impure products by saman vata in grahani (middle part of GI Tract) and useful, pure circulable products.  Samana vata analyzes and separates the useful products (prasada) and waste (kitta). Useful products get absorbed by rasayani (villi) of the intestine, sent to the micro channels (srotas) by vyanvata, simutaneouly, to the entire body. Waste products are excreted out by apaan vayu through urine, feces and sweat.

Now second and third phase of digestion process occur simultaneously in the srotas (microchannels). 5 bhuagnis work on the formation of anatomical structure of the body from respective panchamahabhuta in the form of micro channels, by digestiing needful components present in biofluid. Each gross and subtle particle of body is panchbhoutik, but each one is having different proportion of mahabhuta.
