Rasa dhatu is formed when agni digests food. When food is completely digested with the help of normally secreted digestive juices, the nutritive part of the digested food is called as rasa. This nutritive juice nourishes all cells and tissues of body. It is analogous to extra cellular and intracellular fluids.
Importance of rasa:
“Rasajam purusham vidyaat rasam rakshet prayatnatah
annath paanathcha mathimaan aahaaraatch apyathandritah”
Rasa dhatu contains all the nutients required to nourish body. Hence ayurveda achaaryas mention human body as product of rasa.
