Cassia Cinnamon
Cinnamon is a good source of coumarin, a blood-thinning substance. Coumarin also helps with the production of warfarin, a blood-thinning drug. Studies show that eating small amounts of cinnamon in your diet can help improve the activity of other natural blood thinners. More research is needed to understand the effects of cassia cinnamon on blood clotting.
Studies show that people who use large doses of cinnamon for a long time are more likely to develop liver conditions. You can use the cassai cinnamon in powder form in cakes, drinks, and baked goods. You can also add a little bit to savory dishes.
