The impact of treatment with saline (N) or with different concentrations of fermented Rhizoma Atractylodis Macrocephalae-1 (FRAM-1) or fermented Rhizoma Atractylodis Macrocephalae-2 (FRAM-2) formulations on the viability of RAW264.7 cells. The cells were treated for 24 h with the indicated concentrations of FRAMs followed by the assessment of cell viability. The detailed treatment regimen and experimental conditions are described in Section 2. The viability of the cells that were treated with saline was set to 100%. The data are expressed as the mean ± SD, n = 4. No statistically significant differences were observed between the treatment groups. FHE: fermented herbal extract.
