Standardization Of Aaturahasta Prasrita Pramana Of Vasti- An Observational Study

Background: In Ayurveda, accurate dosage (Matra) plays a vital role in the effectiveness and safety of Panchakarma therapies. Aaturahasta Prasrita Pramana is the classical standard for determining the dose of Vasti Dravya (enema fluid). However, its practical standardization for different age groups has not been systematically validated in contemporary clinical settings. Objectives: To observe, measure, and standardize the Aaturahasta Prasrita Pramana for Vasti in different age groups using actual patient’s hand measurements to ensure accurate dosing in clinical practice. Methods: A cross-sectional observational study was conducted on 900 voluntary participants, divided into three age groups: Group A (6–7 years), Group B (12–13 years), and Group C (18 years and above), with 300 participants in each group. Participants were asked to hollow their palm to hold liquid (Aaturahasta), and the volume was measured using Madhutailika Vasti fluid. Mean, standard deviation (SD), and standard error of mean (SE) were calculated for each group. ANOVA and Tukey’s post-hoc tests were applied to compare groups. Pearson correlation tested the relationship between age and measured volumes. Results: The mean Prasrita values were: Group A: 9.67(in ml) ± 0.77 ml, SE: 0.04 Group B: 20.31(in ml) ± 1.16 ml, SE: 0.06 Group C: 31.93(in ml) ± 3.55 ml, SE: 0.20. ANOVA showed a statistically significant difference (p < 0.0001) between all groups. The correlation among groups was negligible, supporting distinct age-wise dosage standards. Conclusion: The study validates the relevance of Aaturahasta Prasrita Pramana and provides age-specific standardization for clinical use of Vasti in Panchakarma. This practical measure aligns classical references with contemporary practice, ensuring safe and effective personalized dosing.
