Since ancient times, cinnamon has been used for its aroma and medicinal benefits. The benefits of cinnamon are mainly due to its antioxidant properties that can treat an array of medical conditions (1).

Several studies showed that cinnamon could combat free radicals and microbes. However, researchers are still investigating its traditional use against cancer and related inflammatory conditions (1).

A cross-sectional study conducted on 703 Midwestern US adults found that 50% of the participants were familiar with different ethnic spices. Out of these, 56% of them used cinnamon regularly to promote good health and wellness. Furthermore, out of the 56%, 106 participants used cinnamon daily while 578 participants had used it at least once.

Scroll down to learn more about the benefits of cinnamon, its types, its nutritional profile, and its risks.

It may interfere with medications for diabetes, heart disease, or liver disease and may cause allergic reactions, liver damage, and complications during surgery.

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 polyphenoli  XNaturally occurring organic compounds found largely in fruits and vegetables with disease-fighting properties. 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 by its anticancer composition (6).

In mice studies, the cinnamaldehyde from cinnamon reduced the volume of tumors and new vessels in melanomai  XThe most severe type of skin cancer that develops in the cells that produce melanin (the natural skin pigment). 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).

Some research shows that a combination of diet and cinnamon supplementation can aid in blood sugar regulation 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 keratinocytesi  XThe primary type of cells found in the outermost layer of the skin, which play a key role in the skin's defense against infections. 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).

This graph from a study in the International Wound Journal shows the antifungal properties of cinnamon samples. When compared to C1 cinnamon-loaded fibers, raw cinnamon powder has a larger inhibition area. Also, there were no inhibition zones in virgin PCL fibers because these bandages were free of cinnamon extract. However, as the concentration within the fibers increases from 6 to 12 g/24 mL, the antifungal activity becomes more potent, as evidenced by larger inhibition areas.

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 

Cinnamon powder in a bowl

  • 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. Cinnamon powder benefits you in the same way raw cinnamon does, but the powder form makes it easier to consume and to be used in everyday cooking.

  • 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 hepatitisi  XAn inflammatory condition of the liver caused by various viruses, drugs, certain genetic disorders, and chemicals. . 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

Cinnamon may lower blood sugar and blood pressure levels (12),(9). While this could be good, those who are on medications for treating high blood sugar or blood pressure must exercise caution.

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, hamper brain function, and irritate the mucous membranes (27).

Cinnamon inhalation was also found to cause pulmonary inflammation and scarring (27).

In severe cases, it may also lead to aspiration pneumoniai  XAn infection in the lungs caused by bacteria and viruses that inflame the air sacs and cause them to accumulate fluid. , possibly leading to permanent scarring of lungs and their eventual collapse (27), (28).

Infographics: Benefits and Side Effects Of Eating Cinnamon

Cinnamon is perfect for adding a rich earthy flavor and sweet aroma to curries, sweets, or coffee. Its wide array of benefits has made it an essential spice, but it also comes with its set of side effects. Check out the following infographic to learn how cinnamon affects your health before adding it to your diet.

Cinnamon exhibits several antioxidant and anti-inflammatory properties. It may help reduce cancer risk, promote heart health, regulate blood sugar levels, improve digestive system function, and promote oral health. However, excess consumption may harm the liver, lower blood pressure way too much, and cause allergies. Be wary of cinnamon intake before surgery as it can interfere with anticoagulants drugs. Taking cinnamon in moderation is ideal.
