(A) Fluorescence intensity of the HUVECs incubated in 30 mM glucose after treatment with the various concentrations of rooibos tea extracts (mg/mL), 30 mM glucose without treatment (HG control) and 5.6 mM glucose without treatment (LG control). (B) Fluorescence intensity of the HeLa cells treated with the various rooibos tea extracts and untreated with the rooibos tea extracts (untreated control). *p < 0.05 versus the high glucose (HG) control or HeLa cells without any treatment. **p > 0.05 versus the low glucose (LG). HUVECs = human umbilical vein endothelial cells.
