Assessment of the biosafety profile of Galium verum in vitro on myoblasts and in ovo on chorioallantoic membrane

Figure 6 Anti-irritative hen’s egg chorioallantoic membrane test. Stereomicroscopic images of the chorioallantoic membrane treated with controls [H₂O used as negative control; sodium dodecyl sulfate (SDS) 1% used as positive control) and test samples [ethanolic extract of Galium verum (Gv_EtOH) 200 μg/mL] before treatment (t0) and 5 min post-treatment (t5). Scale bars represent 200 μm.
