Preparation of Coronavirus nosodes sourced from a clinical sample of SARS-Cov-2 positive patient, inactivated strain, and spike glycoprotein

Abstract

Introduction
 Nosodes, the homeopathic preparations sourced from biological materials including clinical samples, cultures of organisms, and diseased tissues have been in use against the source-specific infections as well as other diseases. The nosodes have demonstrated some efficacy in managing epidemics, such as influenza, dengue, and leptospirosis. This article presents the need and process of development of nosodes from the SARS-CoV-2 to explore its prophylactic and therapeutic potentials against certain related viral diseases.
 
 MATERIALS AND METHODS
 A clinical sample of SARS-Cov-2 positive patient, based on the cycle threshold (CT) value of the qRT-PCR, heat-inactivated SARS-CoV-2, and spike glycoprotein all were processed for making nosodes as per the method described in Homoeopathy Pharmacopoeia of India. Molecular tests, such as qRT- PCR and sterility tests were performed to establish the live organisms, RNA material, and the absence of contamination.
 
 RESULT
 Three variants of Coronavirus Nosode were developed using a clinical sample, heat-inactivated SARS-CoV-2, and spike glycoprotein. In potencies 3c and above, no detectable SARS-CoV-2 RNA material was found by PCR. The analytical results for nosodes were reported as compliant for sterility testing as per the IP.
 
 CONCLUSION
 Three variants of Coronavirus nosodes were prepared which need to be evaluated further through pre-clinical and clinical studies.
