Cinnamon is a spice derived from the inner bark of trees belonging to the Cinnamomum genus.

It is commonly used as a flavoring agent in sweet and savory dishes, as well as in traditional medicine.

There are two main types of cinnamon: Ceylon cinnamon and Cassia cinnamon.

Ceylon cinnamon, also known as true cinnamon, is milder and sweeter in taste, while Cassia cinnamon is stronger and more pungent.

Health Benefits of Cinnamon

Cinnamon is known for its many health benefits, including its ability to lower blood sugar levels, reduce inflammation, and fight bacterial and fungal infections.

It is also high in antioxidants and can help improve heart health and brain function.

Some studies have even suggested that cinnamon may have potential benefits for sexual health, such as increasing libido and improving erectile dysfunction.

Common Side Effects of Cinnamon

While cinnamon is generally safe for most people when consumed in small amounts, excessive consumption can cause a range of side effects. Some of the most common side effects of cinnamon include:

  1. Mouth Irritation: Consuming large amounts of cinnamon can cause irritation and burning sensation in the mouth and throat.
  2. Skin Irritation: Topical use of cinnamon oil or powder can cause skin irritation, redness, and rash.
  3. Digestive Issues: Cinnamon can cause digestive problems such as diarrhea, nausea, and stomach cramps in some individuals.
  4. Liver Damage: Cassia cinnamon contains high levels of coumarin, a compound that can cause liver damage when consumed in large amounts.

Cinnamon Allergy and Sensitivity

While rare, some people may be allergic or sensitive to cinnamon, which can cause symptoms such as itching, swelling, and difficulty breathing. Individuals with liver disease or taking medication that affects the liver should also be cautious about consuming large amounts of Cassia cinnamon due to its coumarin content.

How to Use Cinnamon Safely

To avoid the potential side effects of cinnamon, it is important to use it in moderation and according to the recommended dosage. For most people, consuming up to 1-2 teaspoons of cinnamon per day is considered safe. It is also recommended to choose Ceylon cinnamon over Cassia cinnamon, as it contains lower levels of coumarin.


Cinnamon is a popular spice with many health benefits, but it can also have side effects when consumed in large amounts or by certain individuals.

If you experience any adverse effects after consuming cinnamon, discontinue use and consult a healthcare professional.

By using cinnamon in moderation and choosing the right type, you can enjoy its many health benefits while avoiding any potential risks.
