In brief: Yes

Warfarin is the most common drug to show a change in effectiveness with the use of herbal supplements.
Among them, st. John's wort and ginko biloba are the most commonly reported to interact with warfarin, the first increases the risk of clotting while the second increases the risk of bleeding.
