How much amount of cinnamon do I have to consum a day to have a natural miscarriage?

It doesn't work. Cinnamon in any amount will not induce a miscarriage.
Does not work. Eating cinnamon will cause you to abort your pregnancy. I would not advise eating more than a normal amount of cinnamon as it may make you sick. It will not cause you to miscarry. See a doctor to discuss all of your options for your pregnancy. Consider placing the baby with a loving family through adoption. There are thousands of families on waiting lists.
