Trypan blue viability and LDH cytotoxicity assays.

Groups	Viability percentage	LDH cytotoxicity
Control	83.83 ± 1.28	0.3490 ± 0.02
0.5% DMSO	82.83 ± 0.98	0.3677 ± 0.02
5 μg/mL RFRA	71.33 ± 2.75∗∗	0.4580 ± 0.07∗∗
10 μg/mL RFRA	61.50 ± 2.54∗∗∗	0.5328 ± 0.06∗∗∗
20 μg/mL RFRA	52.50 ± 3.34∗∗∗	0.5943 ± 0.07∗∗∗
40 μg/mL RFRA	41.00 ± 3.59∗∗∗	0.6508 ± 0.06∗∗∗

Values are mean ± standard error of six independent assays performed in duplicates. The significant differences between treated and controls groups are shown as ^∗∗∗ P < 0.001 and ^∗∗ P < 0.01. (RFRA: R. fairholmianus root acetone extract; LDH: lactate dehydrogenase; DMSO: dimethyl sulfoxide.)
