'''Nourishment of dhatu''':

'''Nourishment of dhatu''':

The dhatus are formed from prasada (first transformed food into ahara -rasa (nutrient fluid). This nutrient fluid nourishes body components in sequential pattern. It first nourishes the rasa dhatu, then rakta, then mamsa etc. The nutrients present in the food nourish respective dhatu qualitatively and quantitatively. [Cha. Sa. Sutra Sthana 28/4]

It first nourishes the [[rasa dhatu]], then [[rakta]], then [[mamsa]] etc. The nutrients present in the food nourish respective dhatu qualitatively and quantitatively. [Cha. Sa. Sutra Sthana 28/4]

Furthermore, during the process of metabolism, dhatus undergo a specific pathway through their own characteristic digestive enzymes termed as ‘dhatvagni.  In this process, each dhatu gets converted into two parts: poshya(which nourishes itself) and poshaka (which nourishes others). The poshya fraction is responsible for dhatu’s own nourishment and functions. The poshaka fraction nourishes further other dhatus.

Upadhatu (by products) and mala (waste products) are also formed in this dhatu metabolic process.
