Interaction warnings

Parsley + warfarin

moderate

Fresh parsley is extraordinarily dense in vitamin K1 - about 1,640 mcg per 100 grams, or roughly 62 mcg per tablespoon - so although typical garnish-sized servings are small, large culinary uses (tabbouleh, chimichurri, parsley smoothies, juicing) can deliver enough vitamin K to oppose warfarin and lower the INR.
