The EA fraction of H. cordata inhibits DENV-2 infectivity but is not cytotoxic to BHK-21 cells.

The EA fraction of H. cordata was tested at concentrations of 166.67 μg/mL down to 0.08 μg/mL. The upper plot reveals a distinct trend of DENV-2 inhibition, with the IC50 being 7.5 μg/mL, and complete viral inhibition being achieved at concentrations of 20.83 μg/mL and above. The lower plot shows that no cytotoxicity to BHK-21 cells was evident at various concentrations of the EA fraction tested.
