Minimal cytotoxic effect of raw MH or pMH against human breast and lung cancer cell lines. MDA-MB-231 breast cancer cells (A, B) and A549 lung cancer cells (C, D) were cultured alone or in the presence of MH or pMH at the indicated final concentrations for 24 h (A, C) or 48 h (B, D). The results are expressed as the percentage of viability (mean ± SD) of MH or pMH-treated cell cultures compared to untreated controls and are representative of two independent experiments. Asterisks denote statistically significant differences in viability between the experimental groups compared to control (**P < 0.01).
