Effects of herbal melanin (HM) on the viability of THP-1 (a) and HEK293 (b) cells. Cells were treated with 7.8–500 μg/mL of HM for 24–48 and 72 h. Cell viability was determined using the CellTiter-glo® kit. Control comprises untreated cells. Bar graph presents the percentage cell viability, and results are presented as mean ± SD of three independent experiments. (*), (**), (***), and (****) signify a statistically significant difference (p < 0.05, p < 0.01, p < 0.001, and p < 0.0001, respectively) compared with the control
