Abstract
Introduction: The Tridosha theory, which is the cornerstone of Ayurvedic physiology, governs all the functions of human body and mind. Tridosha are responsible in determining ones Prakriti and their functional status may vary in different Prakriti . Therefore, this study was planned to find out the variation in functional status of different types of Pitta, using certain objective parameters
Material and methods: 201 young healthy volunteers of both genders of age group 20-35 years, belonging to different Prakriti were selected during the period of January 2016 to January 2017, after obtaining their written consent from the student community. Serum level of triglycerides, cholesterol, total protein and glucose level wasestimated for Pachaka Pitta , hemoglobin concentration for Ranjaka Pitta, visual acuity for Alochaka Pitta, memory and reaction time for Sadhaka Pitta and RGB value for Bhrajaka Pitta were measured. Result: The function of Ranjaka, Bhrajakaand Sadhaka Pitta was found better in Pitta Prakriti individuals followed by Kapha Prakriti and least in Vata Prakriti individuals. As mean values of hemoglobin, RGB values and STM and LTM, were highest in Pitta Prakriti and lowest in Vata Prakriti individuals. Incidence of emmetropia and myopia do not vary significantly. For the functional status of Pachaka Pitta no inference can be drawn which may be due to various confounding factors affecting biochemical parameters, small sample size and homogenous population.
Conclusion: Functional status of Pitta Dosha do vary as per Prakriti. This study should be conducted in large sample size to get a reference range of all these parameters in different Prakriti, which can also be used as a tool to assess the functional status of Pitta Dosha and Prakriti too.

Key words: Pitta, Prakriti. Memory, RGB, Reaction time .
