Dosha, dhatu and mala are the basic elements of human body. Amongst these doshas are more important. Principle of ‘Purusha-loka sammit nyaya’ (Theory of macro and micro cosmos) explains that Kapha, Pitta, Vata maintain body functions, same as the moon, the sun and the wind do it in the nature.
The pathways within the human body which communicates and links the different corners. The pathways which help in manufacture and transportation of essential ingredients which support the life entity, the basic amenities needed to manufacture and create the tissues of the body and to flush out the unnecessary things which contaminate the inner sanctum.
Living body is continuously subjected to wear and tear process. Dhatus needs constant nourishment. Nourishment of the body or dhatu depends upon the quality of food. Food is converted to body constituents by the process of digestion. Panchabhautika food which consists of all six rasas is able to nourish Panchabhautika body.
Upadhatu or sub tissues are byproducts of dhatus. They do not support the life like dhatus. When damaged secondary tissues takes longer time for healing than the main tissues. Generally main tissues except shukra, do not leave the body, while upadhatu can leave the body without harming the body.
Formation of dhatu is a continuous process. Charaka has compared dhatu formation to fetching of water with pulley from well. Charaka further elaborates that dhatu formation depends on activity of dhatu-agni.
Moolasthanas are the sites of utpatti (formation) or vahana (transportation) of a particular substance to which the strotas belongs. They can also be the easiest sites for the examination of that strotas. Moolasthana of strotas controls all other organs related to that channel. Sometime the root of channel is the easiest one for its examination. Hence examination of the moolasthana is important for clinical examination.
Internal lining of the different dhatus, organs is called as kala Kala can be compared with mucous membrane or the membrane that produces particular substance.
The term ‘Strotas’ means channel or system in which some tissue or other material is formed, secreted or transported.
The human body continuously undergoes wear and tear. Formation of new dhatus and destruction of old one is a continuous process. During childhood, rate of tissue formation (anabolism) is rapid while in old age rate of tissue deterioration (catabolism) is more.
