Dr. Vikas Bhardwaj*, Dr. Pankaj Sharma, Dr. Sahana C.
ABSTRACT
Bija Chatustaya, also known as Chikitsa Chatustaya, is an important conceptual framework described in Sushruta Samhita, comprising Purusha (individual), Vyadhi (disease), Aushada (medicine), and Kriya Kala (timing of therapeutic intervention). These four interrelated components provide a systematic foundation for Ayurvedic diagnosis, individualized treatment planning, and therapeutic decision-making. The present conceptual review examines their classical significance, clinical applications, and potential relevance to contemporary research. Purusha emphasizes individual assessment; Vyadhi focuses on the identification, classification, and progression of disease; Aushada concerns the rational selection and administration of medicines and therapeutic measures; and Kriya Kala highlights the importance of timely intervention. Clinically, their integration supports comprehensive patient assessment, appropriate treatment selection, and systematic monitoring of therapeutic responses. From a research perspective, the framework offers a basis for developing standardized assessment criteria, investigating diagnostic consistency, evaluating treatment outcomes, and designing observational and comparative clinical studies. However, the reproducibility, predictive utility, and clinical effectiveness of its individual components require systematic investigation. Integrating classical textual interpretation with contemporary research methodology may facilitate the critical evaluation and evidence-informed application of Bija Chatustaya in Ayurvedic practice.
