Cinnamon is a potent spice. It has been used for thousands of years not just for its aroma, but for its powerful medicinal properties as well. The most important properties of cinnamon are those of its antioxidants (1).
Cinnamon may have a direct action against oxidants and microbes, and studies emphasize the need for more research to confirm the traditional uses of this spice against cancer and other inflammatory disorders (1).
In this post, we explore what research has stated about cinnamon and its beneficial effects.

What Are The Benefits Of Cinnamon?
1. Has Powerful Antioxidant Properties
The cinnamon bark contains procyanidins and catechins, both of which are powerful antioxidants (1).
In a study comparing 26 spices, cinnamon was found to show the highest antioxidant activity. Cinnamon could be used as a potent antioxidant in food and for other commercial purposes (1).
Cinnamon also ranks high on the ORAC scale. ORAC, or oxygen radical absorbance capacity, is a measure of the total antioxidant capacity of a food ingredient. In a report published by the United States Department of Agriculture, cinnamon ranks #2 in the foods tested for their ORAC values (2).
2. May Fight Inflammation In Your Body
In a study, cinnamon water extract was found to have anti-inflammatory properties. This observed anti-inflammatory effect of the spice was thought to originate from its polyphenol content (3).
Various derivatives of cinnamaldehyde (a compound in cinnamon) were also recognized for their anti-inflammatory potential. This could be attributed to their ability to inhibit the production of nitric oxide (4).
Nitric oxide is considered a pro-inflammatory mediator. It has an anti-inflammatory effect under normal conditions. Research shows that nitric oxide inhibitors serve as important therapeutic agents in the management of inflammatory conditions (5).
3. May Offer Protection Against Cancer
Laboratory studies report that cinnamon may help reduce the risk of colon cancer. This effect could be attributed to its ability to fight inflammation and induce cancer cell death (6).
In mice studies, the cinnamaldehyde from cinnamon reduced the volume of tumors and new vessels in melanoma cells. Also, cinnamaldehyde, when combined with other chemotherapeutic agents, was found to exert a synergistic effect in treating colorectal carcinoma (7).
4. May Promote Heart Health
A study shows that taking cinnamon every day can reduce levels of triglycerides, LDL cholesterol, and total cholesterol in individuals with type 2 diabetes. Including cinnamon in a diabetic diet can reduce risk factors associated with cardiovascular disease (8).
The spice was also found to reduce serum glucose levels in people with diabetes (8).
In another study, the consumption of cinnamon was found to be associated with a short-term reduction in blood pressure. Though the spice shows some promise in this regard, more long-term studies are warranted to understand the clinical potential of cinnamon on blood pressure control (9).
5. May Regulate Blood Sugar Levels
Some research shows that a combination of diet and cinnamon supplementation can reduce blood sugar levels better than diet alone (10). The spice was found to be as effective as certain diabetes medications in this regard.
Data strongly supports that compounds in cinnamon function to alter control over carbohydrate metabolism. However, there is a need for further research in this area (10).
The antioxidants in cinnamon could also help. A study supports the hypothesis that the inclusion of water-soluble cinnamon compounds in the diet could reduce the risk factors associated with diabetes (11).
Cinnamon exhibited the potential to lower blood glucose levels in animal models and humans. However, most of these studies had a short duration, stressing on the necessity for more extensive studies (12).
6. May Improve Digestive Health
Some research shows that cinnamon roots serve as a hepatic stimulant. They improve bile production, eliminate toxins, and restore electrolyte balance and hydration. These factors may help enhance digestion (13).
7. May Promote Oral Health
Cinnamon can have a beneficial effect on oral health. It is used for treating toothaches and oral infections, thanks to its antibacterial properties (14). The spice may also help eliminate bad breath (14).
There is some evidence that cinnamon may also help heal a sore throat (15). However, we need more research in this regard.
8. May Enhance Skin Health
Research states that cinnamon extract could be useful in anti-aging treatment of the skin. The cinnamaldehyde in the spice was found to promote the expression of collagen (16).
Another study conducted on human keratinocytes showed the antioxidant effects of cinnamaldehyde and its potential in treating skin disorders (17).
Cinnamon bark essential oil was found to have anti-inflammatory effects, and some models suggest its use in treating inflammatory skin conditions (17).
Cinnamaldehyde may also be beneficial in wound healing, owing to its antimicrobial and anti-inflammatory properties (17).
However, we need more research to evaluate cinnamon’s efficacy and safety with respect to skin health.
9. May Help Promote Hair Growth
In rat studies, topical application of cinnamon essential oil was found to increase hair length and diameter of hair follicles (18).
Cinnamon contains procyanidins. These compounds were found to induce the anagen phase of hair growth in mice studies (19). Anagen is the active growth phase of hair follicles.
These are the various ways cinnamon could benefit you. In the following section, we will look at the nutritional profile.

Though cinnamon could have certain essential nutrients, it is important to pick the right type. Cinnamon is available in different types, but not all are created equal.
Different Types Of Cinnamon (And Which Is The Best)
Cinnamon comes from the inner bark of Cinnamomum verum trees that usually grow in Sri Lanka. It has a sweet and savory flavor. Cinnamon is available in different types, and what differentiates them is their coumarin content.
Coumarin is a natural substance in cinnamon that may cause liver damage (20). Hence, if you are consuming cinnamon, you must ensure it contains as little coumarin as possible.
There are four types of cinnamon – Indonesian cinnamon (contains 2.15 grams of coumarin per kg), Saigon cinnamon (6.97 grams/kg), Cassia cinnamon (0.31 grams/kg), and Ceylon cinnamon (0.017 grams/kg).
Ceylon cinnamon, also known as True Cinnamon or Mexican Cinnamon, is the safest type of cinnamon. But how can you identify it? You cannot tell the difference when you buy cinnamon in powder form. But when you buy cinnamon sticks, the one with the thin layer is Ceylon cinnamon.
You can get your Ceylon cinnamon sticks from Walmart or online. You can include them in various dishes as well. But be wary of the dosage. It is important to know how much of cinnamon you can take.
How Much Of Cinnamon Can You Take?
The tolerable daily intake of coumarin is 0.1 mg/kg of body weight (21). This is the amount of coumarin you can take without experiencing side effects (we will cover them in a later section).
From over 60 ground cassia cinnamon samples from the Czech retail market, twelve were found to have high levels of coumarin. The mean coumarin levels ranged from 2 to 7 grams for every kilogram (22).
Though the amounts may vary depending on the place of purchase of cinnamon, it is important you exercise caution. We do not recommend you have more than 1 teaspoon of cinnamon a day. Also, check with your doctor about the cinnamon dosage.
There are different ways you can incorporate cinnamon into your diet. Keep reading to find out how.
How To Take Cinnamon
- As Cinnamon Powder
You can use the powder in cooking. Add a pinch of it while preparing your favorite dish. You can also add the spice to your morning oatmeal.
- As Supplements
You can also use cinnamon supplements. Ensure you check with your health care provider or nutritionist about the right brand and safety.
- As A Liquid Concoction
Add a pinch of cinnamon to plain hot water and drink it up. You can even add a few drops of lemon. Adding a pinch of cinnamon to your morning tea or coffee also helps.
No matter how rosy cinnamon is, not everything about it is desirable. It does have its share of side effects.
What Are The Side Effects Of Cinnamon?
- May Cause Liver Damage
As discussed, coumarin in cinnamon may damage the liver. In mice studies, coumarin caused liver tumors (23).
In a study, a 73-year-old woman who took cinnamon supplements for a week had complained of severe abdominal pain, vomiting, and diarrhea. The lady was subsequently diagnosed with hepatitis. The coumarin in the cinnamon supplement was linked to the symptoms (24).
The coumarin in cinnamon may also interact with liver medications. Hence, please exercise caution. Cinnamon must be avoided along with hepatotoxic drugs (24).
Ceylon cinnamon could be the preferred choice, but it is best to limit its intake. If you have liver issues, stay away from cinnamon altogether.
- Low Blood Sugar And Low Blood Pressure
Excess intake of cinnamon, in such cases, can cause your blood sugar and blood pressure to fall too low.
If you are taking medications for any of these conditions, check with your doctor. They might adjust your dose accordingly.
- May Cause Allergies
Cinnamaldehyde in cinnamon may cause shortness of breath, throat or chest irritation, wheezing, coughing, or a burning sensation in the mouth. This may happen to susceptible individuals who are prone to allergies (25).
Cinnamon may also cause mouth sores. In studies, cinnamon-flavored chewing gum was found to cause oral mucosal reactions, including burning sensations in the mouth (26).
- Issues During Surgery
Cinnamon may interfere with blood sugar and blood pressure control during or after surgery. The spice may have some effect on these levels (12),(9). Hence, avoid taking cinnamon at least two weeks before a scheduled surgery.
Apart from these side effects, there is another major concern associated with cinnamon.
The Risk Of Eating Dry Cinnamon
Eating dry cinnamon was turning into a rage with the Cinnamon Challenge. The challenge entails swallowing a tablespoon of dry cinnamon in 60 seconds without drinking any fluids (27).
Cinnamon is a caustic powder and is composed of cellulose fibers. These neither dissolve nor biodegrade in the lungs. Rat studies show inflammation and fibrotic lesions following this procedure. High cellulose content, as in the case with cinnamon, can trigger a hypersensitive reaction and irritate the mucous membranes (27).
Cinnamon inhalation was also found to cause pulmonary inflammation and scarring (27).
Cinnamon is an important spice and can add aroma to foods. While it does have some benefits, the key is to remember the dosage. Avoid taking more than a teaspoon. Usually, a pinch of cinnamon must do.
Try to go for Ceylon cinnamon as it has a far lower coumarin content. Also, refrain from swallowing dry cinnamon as part of some absurd challenge – the results could be life-threatening.
