If you have liver problems or are taking medicine, you should talk to a doctor, but chewing on cinnamon sticks can help. Cinnamon has antioxidants and is thought to lower cholesterol. This well-known spice has been used to treat colds and arthritis. It might also help with inflammation and help diabetics keep their blood sugar level. You can also add cinnamon sticks to hot tea or use them as a garnish.
