Mamsa Upadhatu

The superior byproducts (upadhatu) of mamsa dhatu are tvacha (skin) and vasa (subcutaneous fat). Ayurveda describes seven layers of the skin: the topmost layer is connected to rasa dhatu, the second to rakta dhatu, and the third (subcutaneous tissue) specifically to mamsa dhatu. Each subsequent layer connects to the dhatus in sequence, and broadly all layers except the topmost can be grouped as upadhatu of mamsa.

The inferior byproducts are called khamala—impurities accumulated in bodily spaces. These include nasal crust, earwax, sebaceous secretions, tartar on the teeth, and smegma. Kha means space and mala means impurity. If mamsa dhatu agni is low, there is undue production of khamala.
