European health agencies have warned against consuming high amounts of cassia bark, one of the four species of cinnamon, because of its coumarin content.[not in citation given][13] According to the German Federal Institute for Risk Assessment (BFR), 1 kg of (cassia) cinnamon powder contains approximately 2.1 to 4.4 g of coumarin.[14] Powdered Cassia Cinnamon weighs 0.56 g/cc;[15] therefore, 1 kg of Cassia Cinnamon powder is equal to 362.29 teaspoons (1000 g divided by 0.56 g/cc multiplied by 0.20288 tsp/cc). This means 1 teaspoon of cinnamon powder contains 5.8 to 12.1 mg of coumarin, which may be above the Tolerable Daily Intake for smaller individuals.[14]
