'''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]

[[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.
