Cinnamon (Cinnamomum verum) is a spice made by the bark of a tropical evergreen tree. There are different kinds and species of cinnamon, such as:

  • Cinnamomum Cassia (or known as Chinese cinnamon)
  • Ceylon cinnamon (Verum, Sri Lanka cinnamon, or Cinnamomum Zeylanicum)
  • Burmannii (Korintje, Padang cassia, or Indonesian cinnamon)
  • Cinnamomum tamala (Indian bay leaf, Tezpat, Tezapatta, or Malabar leaf)
  • Loureiroi (Saigon cinnamon, Vietnamese cassia, or Vietnamese cinnamon)
  • Citriodorum (Malabar cinnamon)

Cinnamon is widely used in the health and fitness industry as a weight loss supplement, as it’s effective at stabilizing blood sugar levels and reducing hunger.

Cinnamon is also widely used in commercial food products, added into:

Cinnamon is one of the most used cooking spice in the world. It’s mostly used in African, Asian, and Tropical cuisines and areas such as:

  • Central Asia (the Middle East)
  • China
  • East African countries
  • North African countries
  • India
  • Morocco
  • Mexico
  • The Caribbean

All types of cinnamon are powerful preservatives, similar to salt. Their chemicals are used in pickling brines and manufactured food preservatives, including cinnamate, cinnamic acid, and cinnamaldehyde.

In addition to adding an earthy flavor to cooking recipes and preserving food, cinnamon has many health benefits with few side effects.

Cinnamon contains many essential oil and healthy plant-based compounds that contribute to its list of beneficial effects. Cinnamon contains essential oils such as:

  • Cinnamate
  • Cinnamic acid
  • Cinnamyl Acetate
  • Eugenol
  • Eugenol Acetate
  • Cinnamaldehyde

These healthy compounds also have other health benefits, since these essential oils and antioxidants are anti-inflammatory, antidiabetic, anticancer, antiviral, and antimicrobial.

Studies have also found that these antioxidants lower the risk of cardiovascular disease, cancer, heart disease, Alzheimer’s disease, and Parkinson’s diseases.

Origin and History

Cinnamon has been traditionally used in ancient and modern culture as an aromatic cooking ingredient and for medicinal uses

cinnamon sticks with star anise

Its botanical name, Cinnamomum, is derived from the Hebraic and Arabic term amomon, meaning fragrant spice plant.

Dating back to Ancient Egypt around 2000 BC, cinnamon was highly prized and regarded as a gift for the ancient monarchs, kings, and rulers.

The Egyptians used cinnamon for a variety of purposes including healing, food preservation, improving immune system strength, fighting diseases, and overall health.

The Ancient Egyptian also used cinnamon, along with honey, sesame oil, orange blossoms, henna, as well as tree resin to embalm mummies, prevent food from spoiling, and also burned as an incense.

In the 15th and 16th centuries, cinnamon, willow, roses, fennel, ginger, cloves, and other herbs were used to help cure the sick and prevent symptoms of the Bubonic Plague.

Types of Cinnamon

Cinnamon spices and herbs come in two primary types: Cassia Cinnamon and Ceylon cinnamon.

Cassia Cinnamon

It’s also effective at managing blood glucose levels, keeping your energy levels up, and lowering your hunger cravings.

Cassia cinnamon’s bark is bright and light brown in color. It’s primarily produced in Vietnam, China, and Indonesia – and is mostly imported into Canada as well as the US

Cassia cinnamon is the most common type of cinnamon found in grocery stores.

Ceylon (True) Cinnamon

Ceylon cinnamon (Zeylanicum Cinnamomum) is also known as “true cinnamon”, since it’s a much higher quality cinnamon and is much safer to eat in large amounts. In high doses, cassia cinnamon can increase stress on the liver.

Ceylon cinnamon bark is dense and dark brown in color. Ceylon cinnamon sticks are fine and can be easily broken down into a powder.

Although Ceylon cinnamon loses more flavor during cooking, it’s much more aromatic and gives a light cinnamon flavor to the dish.

Ceylon true cinnamon is also more expensive than cassia, as it’s healthier and much harder to make. It’s mostly produced in Brazil, Sri Lanka, The Caribbean, Madagascar, and India.

Taste and Flavor

Cinnamon has a spicy, robust flavor and can handle high-heat cooking and baking.

Cassia cinnamon has a much stronger and spicier flavor compared to Ceylon. It’s mostly used in Mediterranean recipes.

All species of cinnamon have a mild citrus and deep woodsy flavor, very similar to the flavor of cloves, both of which are 2 major ingredients used in making earl grey tea.

Cultivating, Harvesting, and Planting Cinnamon

All types of cinnamon are harvested from the bark of a tree called, the true cinnamon tree (Cinnamomum Zeylanicum). It’s cultivated by having the bark peeled off the tree with a machete and is left to dry for up to 3 days, depending on the size of the bark.

As the cinnamon bark dries, it starts to curl into itself creating the iconic shape of cinnamon.

Cinnamon trees can also be planted at home, given the right nutrients. The soil should be slightly dry and the tree can then last for years without extra attention or care.

These usually grow up to 3 feet tall in smaller plant pots and can exceed a height of 8 feet in large 12 to 14 inch plant pots.

Growing cinnamon trees indoors can be a quick and easy way to get fresh cinnamon into your meals.

After the tree branches have grown to your liking, trim off a few branches and peel the bark with a paring knife.

Leave the bark to dry for 24 hours at room temperature. After the bark has hardened and curled up you can freely use it in your cooking recipes.

Characteristics of The Tree

The cinnamon tree (Cinnamomum Verum) is an evergreen green from the laurel family (Lauraceae).

Indoors, cinnamon can grow all year-round if it has enough bright light and direct sunlight.

It has light-green oval-shaped leaves that have many lines and ridges. The leaves are between 4 to 7 inches in length.

The cinnamon tree also grows berries that are dark brown and light brown.

They’re very small and have long stems at the bottom of their endosperm, similar to anise seeds. Dried cinnamon berries are also added and mixed into black pepper.

The only parts of the tree that are used is the bark and leaves. Cinnamon leaves can be used in tea and in certain brands of essential oils.

Extracted by steam distillation, cinnamon leaves yield between 0.5% to 1.8% of their mass in essential oil. It contains a lot of antioxidants, mostly containing eugenol.

Eugenol is also found in cloves, nutmeg, cinnamon bark, basil, and bay leaf.

Cinnamon trees also have a maximum height of 31 feet when grown outdoors, and 5 feet indoors.

The bark is reddish-brown and around 1 cm thick. The trunk of the tree can reach a maximum diameter of 2 feet when grown in tropical regions.

Cinnamon Health Benefits

1. Relieves Nausea and Digestive Issues

Both cassia and Ceylon cinnamon can be used to treat nausea, cramps, diarrhea, colds, and hay fever.

Specifically, cassia cinnamon has been scientifically proven to improve vitality and energy, blood circulation, improves heart health, and promote fat loss.

Multiple research papers found that people suffering from type 2 diabetes, taking 25 mg of cassia cinnamon per day for 1 month, found improved blood sugar levels and a reduced risk of heart diseases.

The healthy plant-based compounds and its ability to lower blood glucose can drastically reduce bad (LDL) cholesterol levels, the main contributor to heart disease and plaque buildup.

For thousands of years, cinnamon has been used to improve heart health and prevent diseases.

2. Is Full of Healthy Antioxidants

Both cassia and Ceylon cinnamon are full of extremely healthy antioxidants. Like garlic, oregano, and cumin, cinnamon has many powerful antioxidants and many medicinal health benefits.

Cinnamon consists of many healthy plant-based compounds and powerful essential oils, similar to most other herbs and spices.

Antioxidants are healthy compounds that fight free radicals and cell damage produced by metabolic processes in the body.

Free radicals and cell damage cause tears in the DNA and RNA strands, which accelerates aging, inflammation, neurological diseases, cardiovascular disease, and most notably – cancer.

Antioxidants are used to drastically reduce the impact and damage caused by free radicals. A lot of foods that are high in antioxidants can mitigate these side effects.

The health benefits and healthy properties of antioxidants include:

  • Antimicrobial
  • Antifungal
  • Anticancer
  • Antidiabetic
  • Anti-inflammatory
  • Antisemitic

  5. Menstrual difficulties: excess bleeding, Amenorrhea, Oligomenorrhea, Premenstrual syndrome (PMS), Premenstrual dysphoric disorder (PMDD), and Fibroids
  6. Bacterial infections that cause: Diabetes, Cancer, Dementia and Alzheimer’s Disease, Age-related macular degeneration (AMD), and Arthritis

Cinnamon’s primary antioxidant is cinnamaldehyde, which is uniquely found in cinnamon and has many health benefits.

Other foods such as citrus and fruits, tomatoes, and cocoa powder (chocolate) all contain cinnamaldehyde as well, but cinnamon has the highest concentration.

3. Cinnamon Improves Skin Health

Cinnamon has many antibacterial properties that are great for treating acne, acne scars, and other blemishes.

Similar to coconut oil, cinnamon’s powerful antibacterial and antifungal properties effectively kills bacteria that cause:

  • Acne
  • Folliculitis
  • Rosacea
  • Staph
  • Staphylococcal scalded skin syndrome
  • Impetigo (school sores)
  • Furunculosis (boils)
  • Basal Cell Carcinoma
  • Methicillin (meticillin)
  • Eczema
  • Skin cancer
  • Tropical pyomyositis

An easy remedy for treating acne is by making a natural homemade skin mask by mixing:

  • 1 teaspoon of cinnamon
  • 3 tablespoons of honey
  • 1 tablespoon of melted coconut oil

Applying this natural homemade face mask for 10 to 15 minutes will kill the bacteria on your face and reduce the swelling of any blemishes and bumps. The honey also restores skin moisture, reduces redness, as well as smoothens and softens the surface of your face.

Cinnamon is also found in certain brands of shampoo as it helps boost the health of your hair follicles and increases blood flow, making it healthier and easier to supplement nutrition into your hair.

Because cinnamon also increases blood flow, this allows the body to clean and flush out harmful toxins on, not only the surface of your skin but in your internal organs.

  • Astragalus
  • Coffee
  • Blueberries
  • Green tea
  • Yerba mate
  • Licorice
  • Mulberry
  • Pomegranates and pomegranate extract
  • Basil, oregano, and thyme essential oils

4. Improves Digestive Health

According to the National Health And Nutrition Examination Survey (NHANES), 46% of Americans with at least 70 years old was suffered from a form of metabolic syndrome.

This is due to the increased risk with age and body mass. Of these people:

  • 53% suffered from Abdominal obesity
  • 40% from Hypertension
  • 39% from Hyperglycemia

Multiple research studies have found that taking cinnamon supplements regularly, have improved the health of the digestive tract, overall gut health, and reduced the risk of digestive diseases.

Ingesting 10 to 20 mg of cinnamon can help lower carbon dioxide levels in the gut, reducing flatulence, lowering the body’s temperature, and helps with digestion.

Another study found that cinnamon benefits people who have metabolic syndrome and who are prone to cardiovascular diseases (CVDs).

Some of the observed benefits of cinnamon include:

  • Reduced blood pressure
  • Blood and plasma glucose
  • Obesity
  • Dyslipidemia

Also, cinnamon essential oils have powerful antimicrobial and antifungal properties, which attack bacteria and prevent digestive tract infections and increase nutrient absorption in the gut.

5. Stabilizes Blood Sugar Levels

Hundreds of research papers found that supplementing with cinnamon regularly can stabilize and lower blood sugar levels as well as blood lipids.

These benefits mostly come from cinnamaldehyde, the main active ingredient in cinnamon.

Cinnamon has many beneficial insulinotropic effects, as it’s a necessary peptide released by the small intestine while eating food.

Cinnamon regulates the release of insulinotropic peptides and insulin, which increases insulin sensitivity, regulates insulin release, and lowers insulin resistance in diabetics.

People with diabetes will benefit the most from including cinnamon into their diets.

Proanthocyanidin is a set of polyphenols found in cinnamon, that beneficially changes insulin signaling in fat cells allowing its release to be more consistent. Balancing and maintaining energy as well as blood sugar levels.

A scientific study conducted at the Research Center for Health (RCH) in Grenoble, France found that cinnamon counteracts the negative effects of:

  • Alzheimer’s Disease insulin responses
  • Brain insulin signaling
  • High fat and high sugar diet effects on cognitive health

High fat and high sugar diets are very harmful and have many side effects on blood sugar and insulin.

This is because glucose from sugar is highly refined making it very easy to break down, spiking blood sugar levels. Causing a surge in energy followed by a quick crash.

6. Cinnamon Lowers Cholesterol Levels

Cinnamon sticks have hundreds of studies that show how effective it is at lower cholesterol levels, especially in people suffering from type 1 and type 2 diabetes.

Cinnamon also stabilizes good (HDL) cholesterol and reduces bad (LDL) cholesterol.

However, these health benefits are slightly different depending on the type of cinnamon you take.

Cassia cinnamon is full of coumarin, this makes it have less bioactive ingredients that reduces harmful cholesterol levels.

Ceylon cinnamon is highly effective at reducing cholesterol levels, in addition to being much healthier and safer in larger doses.

A study conducted on various animals who’ve been fed cinnamon supplements found that over 8 days, they all experienced decreased blood pressure levels.

Additionally, 4 Chinese studies have also shown that all patients who took cinnamon supplements had lower recorded blood sugar levels as compared to participants who were given placebo pills.

7. Prevents Heart disease

Cardiovascular and heart disease is the leading cause of deaths worldwide.

Coronary artery disease (CAD) and heart disease are slow-developing illnesses that can cause congestive heart failure, cardiac asthma, chronic chest pains (angina), heart attacks, and strokes.

A poor diet eaten over multiple years can cause high blood pressure, high triglycerides, and high cholesterol levels.

Multiple studies have shown how cinnamon helps reduce the severity of cardiovascular risk factors and heart damage.

Both forms of cinnamon have also been proven to improve blood circulation throughout the cardiovascular system, including the heart.

Cinnamon is full of antioxidants and blood-thinning compounds that improve the health of your blood, veins and arteries, blood circulation, and reduces the risk of cardiovascular disease.

It also helps the body effectively repair itself it acts as a coagulant to prevent bleeding. Cinnamon can also help to remove blood impurities, lower cholesterol, and lower blood sugar.

8. Improves Brain Health and Function

As discussed earlier, all of the antioxidants found in cinnamon can help slow and prevent the effects of aging.

In addition to age-related diseases and illnesses such as:

  • Dementia
  • Alzheimer’s disease

Antioxidants trigger the release of brain proteins that prevent damage and changes to the DNA strands during reproduction.

A study involving mice taking cinnamon for 10 days found that mice who took cinnamon regularly had reduced levels of cortisol and other stress hormones produced, as compared to the group of mice who didn’t.

Also, the mice were measured for precursor proteins that cause Parkinson’s disease and Alzheimer’s disease.

The study also found that the mice who had taken cinnamon had reduced precursors for both degenerative cognitive disorders.

Many animal studies have found that cinnamon can increase levels of sodium benzoate and neurotrophic factors in the brain significantly.

Some of the health benefits of sodium benzoate include:

  • Reduces symptoms of liver disease
  • Schizophrenia
  • Multiple Sclerosis (MS)
  • Anxiety disorders
  • Depression

Neurotrophic factors stimulate the production of new neurons and protect older ones, which can also slow the progression of Parkinson’s disease and Alzheimer’s disease.

9. Has Powerful Anti-Inflammatory Properties

Cinnamon’s anti-inflammatory properties can help ease many types of swelling and inflammatory diseases.

The natural plant-based compounds and antioxidants found in cinnamon have powerful anti-inflammatory and antibacterial health benefits.

There are many health benefits of reducing inflammation, such as:

  • Reduced muscle stress
  • Reduces joint pain
  • Lowers the severity of cramps
  • Prevents diarrhea and gastroenteritis
  • Improves heart health
  • Improves cognitive function and brain health
  • Oral pain, inflammation, infections, and toothaches

10. Reduces The Risk of Cancer

Cinnamon is full of antioxidants which makes it a powerfully anticancer spice.

Antioxidants are highly effective at killing cancer cells and triggers cancer cell death.

Cinnamon also slows and reduces the growth (proliferation) of cancer cells and inhibits them from procreating.

A study conducted by the National Institute of Health in the U.S (NIH) found that earthy cooking spices, like cinnamon, stimulate the production of enzymes in the colon that eliminates:

  • Risk of intestinal cancer
  • Colon toxicity
  • Cancer proliferation

Cinnamaldehyde is the primary compound in cinnamon that triggers cancer cell death (apoptosis) and also inhibits the growth of tumors.

Also, cinnamon’s antioxidants help prevent DNA damage and deterioration, further preventing all types of cancers from forming.

11. Helps with Weight loss

Cinnamon is a widely used supplement in the health and fitness industry, because of its main health benefit which increases fat burning and your body’s metabolism.

Hundred of clinical and research studies have shown that cinnamon increases insulin sensitivity, responsiveness, and production as well as reduces blood sugar.

Both functions are necessary for weight loss, especially at lower body fat percentages.

Cinnamon also boosts your metabolism as it also increases your heart rate, improving blood flow and recovery after training.

Cinnamon is essential to include in any weight loss diet plans and all regular diets, unless you suffer from certain heart conditions.

It also reduces inflammation and water weight since it’s highly antibacterial, anti-inflammatory, and a natural diuretic.

Cinnamon Side Effects and Detriments

Cinnamon is generally a healthy cooking spice that has very few side effects.

However, most types of cinnamon should be taken in moderation as overeating can cause negative effects on the liver, cardiovascular system, and can have negative interactions with medication.

Coumarin is a highly potent natural compound that has strong blood-thinning effects, mostly found in Cassia cinnamon.

Cassia cinnamon is much more harmful in higher amounts, compared to Ceylon.

Coumarin is a colorless solid that can cause several side effects when consumed in high amounts.

While thinning blood can be useful for people who have certain heart conditions and other medical needs, it can be problematic when taken shortly after taking certain drugs and medication.

1. Cinnamon May Cause Liver Damage

stacks of cinnamon sticks and star anise

Studies have found that a large amount of coumarin, which is mostly found in cassia, may cause liver damage and liver toxicity in high doses.

Coumarin can damage the liver and it increases your risk of cancer.

Multiple animal studies have proven that large amounts of coumarin can increase the risk of cancerous tumors in the liver, kidneys, and lungs.

Ceylon cinnamon contains only tiny amounts of coumarin, making it much safer.

In the United States, the recommended dietary allowance (RDA) for cinnamon is 1 teaspoon per day for cassia and 2 teaspoons for Ceylon cinnamon.

These amounts are enough to get all of the researched health benefits such as nutrient absorption, weight loss, and improved heart health while minimizing the risk of side effects.

2. May Cause Allergic Reactions

Although uncommon, some people are allergic to all types of cinnamon.

Allergic reactions are triggered by the cinnamaldehyde compound. Cinnamaldehyde is abundant in both Cassia and Ceylon cinnamon, as well as certain cosmetic products and body washes.

Cinnamaldehyde allergies include reactions such as:

  • Swollen tongue or gums
  • Mouth sores
  • Itching and burning in the mouth and/or throat
  • Difficulties breathing
  • Skin patches
  • Anaphylactic shock (in extremely rare cases)

Your doctor or healthcare provider can give you a skin patch or allergy test if you are concerned about being allergic to cinnamon.

Additionally, never eat large amounts of raw cinnamon powder as it can lead to clogging your airways.

The powder clumps together and may cause choking because the lungs can’t break down cinnamon fibers.

Repeated exposure of cinnamon in the lungs can eventually accumulate inside the lungs and cause infections such as aspiration pneumonia

3. Lowers Blood Sugar Levels

People who suffer from low blood sugar levels should avoid cinnamon entirely.

Low blood sugar can cause many negative health effects such as nausea, vomiting, fainting, and heart failure in extreme cases.

As cinnamon lowers blood sugar levels, it can also amplify these side effects.

If cinnamon is used in excess, it can also cause hypoglycemia, dizziness, fainting, and tiredness. Cinnamon should also be avoided before any kind of surgery.

4. May Negatively Interact With Medications

A lot of health conditions make it so that people who take certain drugs and medications can’t have cinnamon.

People with diabetes, heart disease, and illnesses needing antibiotics can suffer serious injuries by taking cinnamon.

Although cinnamon health benefits, it has quite a few side effects when taken along with certain drugs.

Drugs and meditations that have negative interactions with cinnamon include:

  • Antibiotic medication
  • Diabetic drugs
  • Blood thinners
  • Heart medicines

Overall, cinnamon is a healthy cooking ingredient that contributes to a healthy lifestyle and helps with weight loss.
