Tridoshas Maulik Siddhant
According to Ayurveda, all processes of a human body are believed to be governed by a balance of three doshas. Ayurveda’s concept of the Tridoshas is unique to medical science. Dosha is a Sanskrit word, which means “Abnormal”. It is one of the main parts of the Maulik Siddhant (Basic Principles) of Ayurveda. ‘Tridoshas are considered similar to etiological factors responsible to derange normal health condition. The three main doshas (sometimes translated into English as humors) are: Vata (combination of the space and air elements), Pitta (analogous to the fire element), and Kapha (combination of water and earth elements). However there is no equivalent word to translate “Dosha” in the English language, because the concept of Humor is different to the concept of ‘Ayurvedic Tridosha’.
Ayurveda says the body is made up of tissues (dhatus), waste products (malas), and doshas. It is the Tridoshas’ job to assist with the creation of all of the various tissues of the body and to remove any unnecessary waste products from the body. It is also the tridoshas that influence all movements, all transformations, all sensory functions, and many of the other activities in the human body and mind. Whichever dosha appears to dominate a person’s behavior and physique is called his constitution type. Each constitution type has particular strengths and susceptibilities. There is an interesting parallel with the Western concept of athletic (pitta), leptosomic (vata) and pycnic (kapha) constitutional types.
In a person who is physically healthy, the three doshas are present in appropriate proportions, their quality is pure, and their activities are calm and orderly. That person has strong, stable energy, good digestion, flexible joints, clear thinking, calm demeanor, glowing complexion, and is able to sleep well. In a person who is unhealthy, at least one, but almost always two or all three of the doshas are relatively deficient or excessive, their quality has become impure, and their activities disorderly. These latter two aspects, impurity and disruption, are commonly called “vitiation” (the doshas are “vitiated”), meaning corrupted. A term for imbalance of the doshas is tundoskopa: anger of the doshas, capturing the idea that the doshas have an active role in the disease process, not just a passive one of being deficient or excessive in amount.
According to Ayurveda, the site of the existence of Tridosha has been established by keen observers. Charaka, Sushruta and others have determined the locations in the human body where tridosha mainly exist. Bhav Prakasha clearly locates the part of human body where Tridoshas are presents.
Vata exist below the naval and lower part of body.
Pitta exist in between the naval line and epigastrium line.
Kaphha exist in the upper part of the body above from the epigastrium line, including the thoracic cavity, upper limbs and head.
Although the main sites of Tridoshas are as described above, they work with each other in their respective functions to make equality and harmony in the smooth functioning of the body. In Ayurvedic tradition they play a comprehensive role for accurate diagnosis and treatment of the human body.
Ayurveda divides each Dosha by establishing their functions or physiology in five parts/kinds/bheda. This is known physiology or pathophysiology of the main dosha into the dosha-bheda. Ayurveda have its own principles for perceiving the Physiological basis of diseases.
Each of the three main Doshas are further divided into five types known as dosha-bhed according to their functions allotted in the human body.
