Comparative toxicities of theaflavin-3,3′-digallate, Ginkgo biloba extract, and pomegranate extract towards human oral HSC-2 carcinoma cells, untreated (control) and treated with cobalt chloride. Cell proliferation was quantified with the neutral red assay, a cell viability assay. Data are presented as the mean percent of control ± S.E.M. Data for the theaflavin-3,3′-gallate are from Schuck et al. [19], for G. biloba extract from Babich et al. [13], and for pomegranate extract from Weisburg et al. [14].
