Cinnamon
One of cinnamon's many health advantages is its ability to lower blood sugar and ease inflammation. Additionally, some research on animals and in test tubes suggests that cinnamon may prevent the spread of cancer cells. Cinnamon extract was shown to be able to stop the spread of cancer cells and cause their death in a test-tube study.
Another test-tube investigation revealed that cinnamon essential oil dramatically decreased tumor size and prevented the growth of head and neck cancer cells. Additionally, a study on animals revealed that cinnamon extract caused the death of tumor cells and slowed the growth and spread of tumors. Consuming 1/2 to 1 teaspoon (2-4 grams) of cinnamon daily may help prevent cancer and have additional health advantages like lowering blood sugar and reducing inflammation. To fully understand how cinnamon might influence human cancer development, more research is required.
