Health Benefits Of Cinnamon

What Is Cinnamon?

Cinnamon represents a type of an aromatic spice that originates from the inner parts of trees named Cinnamomum. It has been used in traditional culinars and medicine since Ancient Egypt.

Cinnamon is extracted the specific parts of the cinnamomum tree, and when dried, it forms cinnamon sticks. Such sticks may further form powder.
There are four types of cinnamon: Ceylon cinnamon seum zeylanicum (true cinnamon), Cassia cinnamon, Indonesian cinnamon (Cinnamomum burmanni) and Vietnamese cinnamon (Cinnamomum loureirol).

The main active component of cinnamon is hydrocarbon cinnamaldehyde found in the bark of the plant. The eugenol is found in leaf and camphor in the root. Cinnamaldehyde aids specific flavor and is responsible for the majority of cinnamon’s health benefits.

Biochemical Characteristics

Cinnamon’s main active compounds are cinnamaldehyde (cinnamic aldehyde, 3-phenyl-2-propenal) and eugenol (2-metoxy-4-(2-propenyl)phenol).
Cinnamaldehyde is also present in blueberries and cranberries.

Cinnamon consists of Cinnamon, eugenol, camphor, caryophyllene, terpene hydrocarbos, alpha-bergamotene, alpha-copaene, terpenoids, Cinnamon acetate and trans-alpha-bergamotene.

In leaves there is 1-5% of Cinnamon and 70-95% of eugenol. In cinnamon bark there is 65%-80% of Cinnamon and 5-10% of eugenol. In the root bark there is 60% of camphor.

Numerous health benefits of Cinnamon zeylanicum have been demonstrated, such as anti inflammatory effect, antimicrobial activity, decreased cardiovascular risk, enhanced cognitive function and lower risk of colorectal cancer. (1)

The most prominent health effect of cinnamon has been noted in individuals with diabetes.

Cinnamtannin B1 is the main component in cinnamon that reduces fasting blood glucose, reduces LDL, increases HDL cholesterol, reduces HbA1c and elevates circulating insulin levels.

Cardiovascular Effect

The use of cinnamon has been shown to decrease the risk of cardiovascular disorders.
Cardiovascular Effect In an animal study it has been shown the effect of Cinnamon cassia on patients with ischemic heart disease. Its main components – cinnamaldehyde and cinnamic acid are cardioprotective. They are able to produce nitric oxide that leads to vasodilatation.(2)

Gastrointestinal Effect

Cinnamon has inhibitory role in the digestive secretion and may show antigastric ulcer effect. Its use decreases basal gastric acid levels in pylorus of tested rats.
Further, in tested animals cinnamon extract may significantly reduce the severity of diarrhea. (3)


Cinnamon may reduce the levels of total cholesterol, LDL cholesterol and triglycerides. It has no effect on HDL cholesterol. Thus, it is of benefit in cardiovascular disorders as well as hypertension.


Cinnamon has been shown to reduce blood pressure.


Cinnamon is effective in the reduction of the insulin resistance. Thus, it is of benefit in individuals with diabetes mellitus and its complications such as metabolic syndrome.

Cinnamon decreases postprandial level of glucose interacting with several gastrointestinal enzymes. In that way, cinnamon degrades carbohydrates in the gastrointestinal system.

Cinnamon contains a hydroxychalcone, substance that may show insulin-like functions. Hydroxychalcone enhances glucose cell absorption.(4)

It has been shown that cinnamon water extract may reduce memory impairment in older individuals with diabetes type 2.

Cinnamaldehyde promotes insulin secretion, its sensitivity and regulates protein-tyrosine phosphatase 1B (PTP1B) and insulin receptor kinase.

It is included in the regulation of the expression of peroxisome transcriptional factors such as proliferator-activated receptors (PPARs) that control insulin resistance and adipogenesis.

Weight Loss

Cinnamon reduces glycose postprandial concentratin and regulates insulin levels. It enhances metabolic reactions and leads to overall weight loss.

Kidney Health

Cinnamon has potential to prevent and reduce the extent of diabetic neuropathy and nephropathy.
Bone Health
Cinnamon extracts may be helpful in the inhibition of osteoclastogenesis which is important in the prevention of osteoporosis in diabetes mellitus.


Certain cinnamon extracts are used in the prevention and treatment of various cancer types.
It may decrease the rate of tumor growth as well as neoangiogenesis. It shows toxic effects on tumor cells, leading to apoptosis. In colorectal cancer, it may neutralize certain enzymes in colon, thus protecting against tumor cell growth.(5)

Skin Effect

Cinnamon water extract stimulates type I collagen production through the activation of IGF-1 pathway in human dermal fibroblast.(6) Thus, it is of extreme use in the antiaging process of the skin.

Neurodegenerative Diseases

Neurodegenerative disorders are characterized by progressive loss of the structural and functional attributes of brain cellular components.

Alzheimer’s Disease

Cinnamon contains certain substances that are able to inhibit the accumulation of a tau protein and filament formation in the brain structures that lead to the onset of Alzheimer’s disease.

Parkinson’s Disease

In an animal study, it was shown that cinnamon may cause the regeneration of neurons, better neurotransmitter levels and motor coordination.

Attention Deficit Hyperactivity Disorder

Cinnamon has been applied as a homeopathic regimen in children with attention deficit hyperactivity disorder (ADHD).

Anti Inflammatory Properties

The use of cinnamon may enhance the anti-inflammatory reactions in the body and speed up the recovery. It has potent anti-inflammatory potential due to high level of antioxidants.

Antioxidant Effect

Cinnamon is abundant in polyphenols, thus it is powerful antioxidant.

Antimicrobial Effect

The main active component of cinnamon is Cinnamon. It is active in the fight against numerous types of infections.

Respiratory Infections

Cinnamon oil is used in the treatment of respiratory tract infections.

Respiratory Infections

It is effective in fungal infections. It may as well inhibit bacteria such as Listeria and Salmonella(7)

Teeth Health

Cinnamon is responsible for antifungal and antibacterial effects of cinnamon. It may decrease the incidence of teeth infection.(8)

Antifungal Effect

Cinnamon is effective in fungal respiratory tract infections.

Antiparasitic Effect

Certain oil extracts of leaf and bark of cinnamon are effective against Culex quinquefasciatus, Anopheles and Aedes aegypti mosquitos.


It may even be of benefit in the treatment of human head louse – Pediculus humanus capitis. (9)

Hiv Infection

Recent studies suggest that cinnamon (Cassia species) may be effective in the protection against HIV-1. Further studies are required. (10)

Premenstrual Syndrome

Cinnamon is able to reduce the intestinal and uterine cramps in premenstrual women due to high levels of fiber and manganese.

Female Hormonal Status

It has been noted that cinnamon is of benefit in females with polycystic ovarian syndrome.

It may even improve hormone status, ovarian function and enhance fertility.

Possible Side Effects

The Cassia type of cinnamon consists of high concentration of coumarin (1,2-benzopyrone), a substance that is hepatotoxic and carcinogenic in humans if ingested in larger doses.

In certain individuals, high cinnamon intake may lead to the irritation of oral cavity or the surrounding skin.

Allergic reactions are possible in individuals with atopic constitution.

The consumption of cinnamon should be limited in case an individual is on antibiotics, anticoagulants and certain cardiovascular drugs
