Comparisons of the selectivity index (SI) of antiviral activity on HSV-1 between prophylactic (IVR) and virucidal (DVI) at best time for MBS extract and between that of MBS extract and the standard drug (Acyclovir)

Extract	Protocol vs Protocol	Time vs Time	SI vs SI	P value
MBS	aIVR vs bDVI	1 h vs 2 h	10.9 ± 0.96 vs 18.23 ± 1.69	0.009	Significant
MBS vs Acyclovir	aIVR vs aIVR	1 h vs 1 h	10.9 ± 0.96 vs 15.04 ± 1.9	0.06	Non-significant
MBS vs Acyclovir	bDVI vs bDVI	2 h vs 2 h	18.23 ± 1.69 vs 22.56 ± 1.11	0.05	Non- Significant

Note: ^aIVR: the inhibition in virus infection after specific cell treatment. ^bDVI: the direct virus inactivation
