This paper aims to find commercially available medicinal plants showing antiviral activity in vitro on suid and bovine herpesviruses. The following species were tested: Mikania glomerata, Cymbopogon citratus, Equisetum arvense, Peumus boldus, Solanum paniculatum, Malva sylvestris, Piper umbellatun and Solidago microglossa. The cytotoxicity was evaluated by morphological changes in cells determining the maximum not cytotoxic concentration (MNCC). The antiviral activity was evaluated by viral title reduction. The extracts from Peumus boldus and Solanum paniculatum showed antiviral activity against SuHV-1 with 98% of inhibition. The extract of Peumus boldus also showed activity against BoHV-1 with 99% of inhibition.
