A CONCEPTUAL REVIEW OF DOSHA PRAKOPA NIDANAS THROUGH SCATTERED REFERENCES OF AYURVEDA

It is rightly said, “Ayurvedo Amrutaanaam”. Ayurveda is a life science which explains the tridosha theory. As per Ashtanga Hrudaya, dosha (bioenergy), dhatu (body tissues) and malas (excretory products) form the root of the body. Fundamentals of Ayurveda are explained in Trisutras, i.e. hetu (aetiological factor), linga (clinical features) and aushadha (medicine /treatment). So, 2/3rd of Ayurveda is coming under the purview of Roganidana. It is also said that the manifestation of Roga is nothing but the imbalances in the proportions of dosha observed in the body. Dosha vaishamya (imbalance of dosha) can be seen as a result of dosha vriddhi, kshaya, prakopa etc. Dosha vaishamya, mainly dosha prakopa, is an essential step in the manifestation of samprapti and is understood by assessing the nidana with that of dosha involved in the samprapti. Dosha prakopa occurs due to Gunataha vruddhi after the nidanasevana and thus lead to manifestation of the disease. In this article, an attempt has been made to collect the references, which includes all possible nidanas responsible for the prakopa of doshas.
