Varicella-zoster virus (VZV), a ubiquitous human α-herpesvirus, is the causative agent of chickenpox and shingles. In the present study, we investigated the antiviral activity of a 70% ethanol extract of Lysimachia mauritiana (LME) against VZV. LME strongly interfered with the replication of both laboratory and clinical strains of VZV without affecting the viability of MRC-5 cells. Moreover, LME treatment suppressed the expression of an essential viral transactivator, immediate-early 62 protein

The finding that LME exerts potent inhibitory effects on VZV gene expression and replication supports its potential utility as a therapeutic anti-viral agent. Abbreviations: VZV, Varicella-Zoster virus; IE, immediate-early; LME, ethanol extract of Lysimachia mauritiana; MOI, multiplicity of infection; PFU, plaque forming unit; ORF, open reading frame
