'''Concept of Upadhatu and Dhatumala:'''

Upadhatu and mala are by-products formed during process of metabolism. The by-products are categorized into these two groups according to their functional importance. Dhatu supports the body and nourishes the subsequent dhatu. However,upa-dhatus do not nourish any further element. They only carry physiological functions and only support body.

The other by-products are dhatu-mala or excretory products. They can get easily vitiated by pathogenic factors; hence they are termed as mala.
