EEH, ethanol extract of Houttuynia cordata; FEEH, ethanol extract of fermented Houttuynia cordata.
Sample concentration is 0.5 mg/mL.
All values are mean±SD (n=3).
Means with different superscript letters (^a-c) are significantly different among the samples by Duncan’s multiple range test (p<0.05).
