Dhatus are created nourished and repaired by the juice of a healthy diet. These tissues or dhatus are in fact the product of digested food. This clearly explains the importance that ayurveda places on the food we eat.
The most important difference between Dosha and Dhatus is that the Dhutas perform functions under the fine control of Dosha. The word dhatu means ‘support’ in Sanskrit Dhatus therefore form the infrastructure of the body.
