Standardization of Bindu Pramana of Medicine for Ksheera-Nagara Nasya

Abstract

Ayurveda, the science of life, emphasizes health through Shodhana (purification) and Shamana (pacification) therapies. Panchakarma focuses on Shodhana, with Nasya (nasal administration) being the premier treatment for disorders of the head and neck. As the nose is considered the gateway to the head, Nasya effectively eliminates vitiated Doshas from the supra-clavicular region. Objectives: Therapeutic efficacy in Panchakarma depends heavily on precise dosage. Traditional texts use Bindu as the unit of measurement for liquid medicines. However, a Bindu- defined as the quantity of liquid dripping from an index finger dipped up to the proximal interphalangeal joint- varies based on the liquid's viscosity. This study aims to standardize the Bindu Pramana (measurement) and the total dose of Ksheera-nagara Nasya, as indicated for Shirasula (headache) in the Yogaratnakara. Materials and Methods: Before clinical application, it is essential to convert traditional units into metric measures. Following Vagbhata’s guidelines for Avapeedaka Nasya, a dose of 8 Bindu was selected. The study was conducted on 60 healthy volunteers (aged 18–60 years) to determine the average volume of a single Bindu and the subsequent total dose for Ksheera-nagara Nasya. Results: The study standardized the volume of one Bindu of Ksheera-nagara Nasya at 0.131ml. Consequently, the therapeutic dose of 8 Bindu was calculated to be 1.048ml. Conclusion: Standardizing traditional measurements into metric units ensures accuracy and reproducibility in clinical practice, bridging the gap between ancient methodology and modern pharmacological standards.
