B.   Coenzyme Q10 has minimal effects on warfarin metabolism. It is mainly involved in cellular energy production and does not significantly alter coagulation.
C.   Valerian primarily affects the central nervous system and has no significant interaction with warfarin. It is mainly used for its sedative properties and does not interfere with blood thinning.
