Panorama of Pitta Dosha in Ayurveda
The Tridosha theory, which is the cornerstone of Ayurvedic physiology governs all the functions of human body and mind. Tridosha are responsible in determining one's Prakriti and their functional status may vary in both gender of different Prakriti. No research work is available to assess the functions of Dosha by objective parameters. Therefore, this study was planned to find out the variation in functional status of different types of Pitta, using certain objective parameters, in 201 young healthy volunteers of both gender belonging to different Prakriti. Serum level of triglycerides, cholesterol, total protein and glucose level were estimated for Pachaka Pitta and 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 .Except the functioning of Bhrajaka Pitta, variation in functional status of all type of Pitta was not the same in different Prakriti of both gender. However these findings were not significant which may have occurred due to small sample size and homogenous population. Thus we propose the consideration of sex differences while planning and evaluating the studies that are based on Prakriti.
According to Ayurveda, the traditional system of healthcare of Indian origin, Agni is the factor responsible for digestion and metabolism. Four functional states (Agnibala) of Agni have been recognized: regular, irregular, intense, and weak. The objective of the present study was to develop and validate a self-assessment tool to estimate Agnibala. The developed tool was evaluated for its reliability and validity by administering it to 300 healthy volunteers of either gender belonging to 18 to 40-year age group. Besides confirming the statistical validity and reliability, the practical utility of the newly developed tool was also evaluated by recording serum lipid parameters of all the volunteers. The results show that the lipid parameters vary significantly according to the status of Agni. The tool, therefore, may be used to screen normal population to look for possible susceptibility to certain health conditions.
Several questions are being raised regarding the accuracy of the methods of diagnosis and reporting of various clinical parameters according to Ayurveda in recent times. Uniformity in reporting, issues related to inter-rater variability, uniformity in applying statistical tests, reliability, consistency, and validation of various tools, - are some of the major concerns that are being voiced. Dhatu Sarata is one such domain where no substantial work has been carried out to address these issues. The Sanskrit term "Dhatu" roughly translates as a "tissue." Sarata stands for the status of Dhatu in a given individual, i.e., it describes whether the status is excellent, moderate, or poor. In the available research literature, there are several gaps while dealing with and reporting the clinical assessment of Dhatu. Most of the workers group an individual into any one of the categories of Dhatu Sarata, and this approach neglects the contribution of other Dhatus to the overall Sarata in that individual. In this communication, we propose the usefulness of "weighted mean" in expressing the overall Sarata in an individual. This gives the researcher a freedom of not classifying an individual into any one group of Sarata, while also simultaneously allowing him/her to retain the focus on the status of an individual Dhatu.
Sara is explained in context of 'Dashvidha Pariksha' in Charak Samhita to measure the strength (Bala) of an individual. Haematological parameters are most frequently used in routine investigations. It is obvious that both Sara and haematological parameters are used in ancient and modern science therefore, this study was planned to assess the variation in haematological parameters of different Sara individuals as per sex. Total 254 (156 males and 98 females) healthy individuals between the age of 18 to 35 were included in this study. Assessment of Sara was done in terms of total Sara score by questionnaire type proforma specially designed for this study. Haematological values provide important information about health status of a person like anaemia, polycythemia, any type of infection and others. Haematological parameters were analysed by automatic haematology analyzer. On correlation of the total Sara score and haematological values in male and female, significant variation in total Sara score as well as in haematological values was observed.
