Antibacterial Mechanisms of Swarnaprashana: Integrating in-Vitro Evidence with Ayurvedic and Modern Scientific Perspectives

Abstract

Infectious diseases remain a major cause of morbidity among children because of their immature immune system, while the rapid emergence of antimicrobial resistance (AMR) has reduced the effectiveness of conventional antibiotics. Swarnaprashana, a classical Ayurvedic formulation composed of Swarna Bhasma, Madhu, and Ghrita, has traditionally been used to enhance immunity and disease resistance in children. Although recent in vitro studies have demonstrated its antibacterial activity, the underlying mechanisms have not been comprehensively explained. To critically review and integrate the available scientific evidence on the antimicrobial mechanisms of Swarnaprashana by correlating published in vitro findings with contemporary microbiological knowledge and classical Ayurvedic concepts. A narrative literature review was conducted by analysing published in vitro studies on Swarnaprashana and its major constituents, including Swarna Bhasma, Madhu, and Ghrita. Evidence from microbiology, nanomedicine, pharmacology, and classical Ayurvedic literature was synthesized to explain the possible mechanisms responsible for the observed antibacterial activity. The available evidence suggests that Swarnaprashana exerts antibacterial activity through multiple complementary mechanisms. Swarna Bhasma may disrupt bacterial cell membranes, generate reactive oxygen species, inhibit metabolic enzymes, and interfere with DNA replication and protein synthesis. Madhu contributes through its high osmotic pressure, acidic pH, hydrogen peroxide production, phenolic compounds, and inhibition of biofilm formation. Ghrita primarily functions as a bio-enhancing lipid carrier that improves the stability, dispersion, and delivery of active constituents while also providing antioxidants and immunomodulatory support. The combined action of these components may produce a synergistic antibacterial effect against both Gram positive and Gram-negative bacteria. Current evidence supports the potential antibacterial activity of Swarnaprashana and provides a scientific basis for its traditional use in pediatric healthcare. Nevertheless, the evidence is largely limited to in vitro studies. Further molecular investigations, standardized experimental studies, and well-designed clinical trials are required to validate its mechanisms, establish safety, and determine its therapeutic role in infection prevention and antimicrobial resistance management.
