Withodin B™ is a Phytotherapeutic extraction of Withania somnifera, Polygonum Multiflorum, Apis mellifera propolis, Camellia sinensis, Monoatomic Au, and Cinnamomum verum. Using advanced laboratory extraction apparatus & proprietary production protocols, these phytochemicals are known for their S-Spike protein inhibition properties. 

SARS-CoV-2 engages human ACE2 through its spike (S) protein receptor binding domain (RBD) to enter the host cell. Recent computational studies have reported that withanone and withaferin A, phytochemicals found in Withania somnifera, target viral main protease. Withanone bound efficiently at the interacting interface of the ACE2- RBD complex and destabilized it energetically. The electrostatic component of binding free energies of the complex was significantly decreased. Withanone as a potent inhibitor of SARS-CoV-2 coronavirus entry into the host cells.
