Figure Lengend Snippet: Effect of the aqueous leaf extract of L. rectus (LRAE) on cell viability of ( A ) HaCaT keratinocytes and ( B ) NIH/3T3 fibroblasts through resazurin assay. The results are expressed as a percentage of cell viability compared to the control. Columns and bars represent mean and standard deviation, respectively ( n = 3 independent experiments performed in duplicate). Statistical analysis was performed by one-way ANOVA followed by Dunnett’s Multiple Comparison Test: * p < 0.05, compared to the control.
