CINNAMON VS CINNAMON
If you are consuming cinnamon, maybe you're using the wrong #spice ... actually there are two types of cinnamon on the market: Ceylon cinnamon, called 'true cinnamon', and Cassia #cinnamon', called 'Chinese cinnamon'. They have completely different properties and while the former has many scientifically proven uses in medical field, including the insulin-like action (but without the negative effects of this), the therapeutic effect on the neurons of patients with Parkinson's disease and much more, the second can also become dangerous if taken too generously and has no medical interest. Which kind of cinnamon are you consuming?
it's true that cassia cinnamon can become dangerous if taken too long. This is because it contains a lot of coumarin (unlike ceylon cinnamon).
Coumarin accumulates and damages the liver.
that's correct.
