Critical Analytical Review of Charkokta Jwarahara Mahakashay: Classical Foundations and Contemporary Pharmacological Correlation

Jwara (fever) occupies a central position in Ayurvedic nosology due to its systemic impact on metabolic, physiological, and psychological equilibrium. In the Charak Samhita, Acharya Charaka classified medicinal substances into fifty Mahakashayas based on similarity of pharmacodynamic action, among which the jwarahara Mahakashaya is described as the thirty-ninth group, comprising ten drugs: Sariva, Sharkara, Patha, Manjistha, Draksha, Peelu, Parushaka, Abhaya, Amalaki, and Vibhitaki. This review critically evaluates identity, phytochemical composition, and modern pharmacological evidence to establish the scientific rationale for this grouping. The integrated analysis reveals that Jwarahara Mahakashaya represents a rational, stage-specific, and synergetic therapeutic cluster designed to address Ama pachana, Strotoshodhana, Pittashamana, and immunomodulation in Jwara. The classical concepts correlate meaningfully with contemporary biomedical understanding of fever as an inflammatory and immune-mediated process.
