In the previous section, we learned about some of the varieties available for sale, but what's the difference? It's simple: the difference lies in the coumarin content of each type. You've probably never heard of this word (until you read it in the previous section), right? It's a substance that, if consumed in excess, can cause liver and kidney damage.
It is advisable to take the Ceylon variety, as Cassia has a high coumarin content, so half a teaspoon may contain more than is considered safe for regular users.
I want you to know that occasional consumption of Cassia cinnamon does not pose a health problem, but for those who consume it every day, it is recommended that they opt for the Ceylon variety.
