Comparative toxicities of theaflavin-3,3′-digallate (TFdiG) and Ginkgo biloba extract towards human oral HSC-2 carcinoma cells, untreated (control) and treated with glutathione depleters. 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 TFdiG study are from Schuck et al. [19] and for G. biloba from Babich et al. [13].
