Dosha, Dhathu and Mala form the roots of the body. They play a mutual role right from birth to death. The Dosha (Vata, pitta and kapha) helps for the various function of the body. The Dhathus (Rasa, Raktha,Mamsa, Medha, Asthi, Majja and Sukra) retain and nourish the body. Mala helps to excrete the wastes products from the body. The Doshas regulate the Dhathu and the Mala. When the Doshas are vitiated or disturbed, it affects Dhathu and Mala.
Mala are the waste products that need to be eliminated from the body periodically. It plays a major role in maintenance of health. Not only the feaces, urine and sweat, but also the hair, the nail, ear wax, nose deposite, semen are the waste products of our body. They are produced only when the health is normal. So, one can predict their health status on observation of their mala.
