Dhatu is known to be the Structural and functional unit of our body. It provides strength, Energy, and support to our body. Normal and abnormal functioning of dhatu is important for the overall growth of our body. In Ayurveda Samhitas, it is mentioned that when dhatu is in a normal state it makes the individual healthy. When it gets disturbed it causes disease. It is mentioned here the concept of Dhatu, its anatomy, Physiology, and Pathology and treatment which help us to know the critical aspects. The physiology of dhatu is well explained by Dhatu Poshan Nyaya. It is for 4 types as mentioned in Samhitas i.e. Kshir Dhadhi Nyaya, Kedari Kulaya Nyaya, Khale Kapota Nyaya, Ek Kala Dhatu Poshan Nyaya. With the help of these Nyaya, we understand the formation and nourishment of Dhatu from Ahar Rasa. When the Formation of Dhatu gets disturbed at any level as due to Apathya Ahara Vihar, Agni dushti, Srotodushti, or defective Ahara rasa it results in the formation of diseases. Hence the Pathology of diseases also depends on Dhatu which is well explained by Rogamarga and is similar to Samprapti of diseases. I tried to explain Rogamarga in an elaborate way to know the prognosis and level of diseases because due to advancing modern science the concept of dhatu and the pathway of diseases are unknown to common people. So, this article helps to make every one of the concepts which further help in the diagnosis and treatment of diseases.
