Ceylon cinnamon (Cinnamomum verum) is known as the “real” or true cinnamon. It's more expensive than cassia cinnamon varieties, but is best for this cinnamon tea recipe and has a milder flavor and lighter color.

It's safe to drink as tea, though high doses and certain types can worsen some conditions. Taking large doses of cinnamon for long periods, or drinking a lot of cinnamon tea for a long time, can cause digestive upset. These can include common complaints like nausea, stomach pain, vomiting, and diarrhea.

All cinnamon should have health benefits, but Cassia may cause problems in large doses due to the coumarin content ( 40 ). Ceylon (“true” cinnamon) is much better in this regard, and studies show that it's much lower in coumarin than the Cassia variety ( 1 , 40 ).

Ceylon cinnamon is full of antioxidants, which help your body handle free radicals and lowers your risk of health conditions like cancer, heart disease, and diabetes. Ceylon cinnamon is also rich in the mineral manganese. This mineral helps your body manage the enzymes that produce hormones and help repair your bones.
