Figure 1.

Effect of Digestarom DC (D-DC), grape seed extract (GRS), licorice extract (LIC), menthol (MENT), methyl salicylate (MES), oak bark extract (OAK), oregano essential oil (ORE), plant powder mix (PLA), and tylosin (TYL) on cell viability of intestinal porcine epithelial cells (IPEC-J2). IPEC-J2 were incubated with the test substances for 24 h and cell viability was assessed via the neutral red cell viability assay (NR assay). Relative viability in comparison to the untreated control, which was set to 100%, is displayed. Data represent the mean values and SEM of 4 independent experiments (n = 4). No significant differences were found.
