Cinnamon: A Spice with Many Benefits and Uses

Cinnamon is a spice that comes from the inner bark of several tree species belonging to the genus Cinnamomum. It has a distinctive aroma and flavor that makes it a popular ingredient in many cuisines, especially in desserts, beverages, and savory dishes. Cinnamon has also been used for its medicinal properties for thousands of years, as it may have various benefits for health, such as lowering blood sugar, reducing inflammation, and fighting infections. However, cinnamon also has some potential side effects and risks, especially if consumed in large amounts or in combination with certain medications. In this article, we will explore the different types of cinnamon, the history of its cultivation in Meghalaya, a state in Northeast India, the medical benefits and downsides of cinnamon, and some of the common uses of this spice.

​

Types of Cinnamon

There are two main types of cinnamon that are commercially available: Ceylon cinnamon and Cassia cinnamon. Ceylon cinnamon, also known as true cinnamon or Sri Lanka cinnamon, is native to Sri Lanka and Southern India. It has a lighter color, a thinner bark, and a milder and sweeter flavor than Cassia cinnamon. Ceylon cinnamon is considered to be of higher quality and more expensive than Cassia cinnamon. Cassia cinnamon, also known as Chinese cinnamon, Indonesian cinnamon, or Saigon cinnamon, is native to China, Indonesia, Vietnam, and other Southeast Asian countries. It has a darker color, a thicker bark, and a stronger and spicier flavor than Ceylon cinnamon. Cassia cinnamon is more common and cheaper than Ceylon cinnamon. Most of the cinnamon sold in supermarkets and used in recipes is Cassia cinnamon.

​

One of the main differences between Ceylon and Cassia cinnamon is their coumarin content. Coumarin is a natural compound that has anticoagulant, anti-inflammatory, and antifungal properties, but it can also be toxic to the liver and interfere with blood clotting if consumed in high doses. Ceylon cinnamon contains very low levels of coumarin, while Cassia cinnamon contains much higher levels of coumarin. The tolerable daily intake of coumarin is about 0.1 mg per kg of body weight, or about 5 mg for a 130-pound person. This means that one teaspoon of Cassia cinnamon, which contains about 5 to 18 mg of coumarin, could exceed the safe limit, while one teaspoon of Ceylon cinnamon, which contains only trace amounts of coumarin, would be well within the safe range. Therefore, people who consume cinnamon regularly or take cinnamon supplements should opt for Ceylon cinnamon over Cassia cinnamon to avoid the potential risks of coumarin toxicity.

History of Cultivation of Cinnamon in Meghalaya

Meghalaya is a state in Northeast India that is known for its rich biodiversity, scenic landscapes, and diverse cultures. Meghalaya is also home to naturally grown cinnamon trees, which are cultivated by the local farmers using traditional and organic methods. Cinnamon is one of the important cash crops in Meghalaya, as it provides income and livelihood to many rural communities. Cinnamon cultivation in Meghalaya dates back to ancient times, when it was used as a spice, a medicine, and a gift for monarchs and gods. Cinnamon was also traded with other regions and countries, such as China, Southeast Asia, and Europe, through the ancient Silk Road and other routes.

​

Cinnamon cultivation in Meghalaya is mainly done in the Khasi and Jaintia hills, where the climate and soil are suitable for the growth of the spice. The farmers use the seed propagation method or the stem-cutting method to plant the cinnamon saplings, which are usually ready for harvesting after three years. The harvesting process involves peeling the bark of the cinnamon trees, which is done after the monsoon rains, as the bark is easier to peel when wet. The peeled bark is then dried in the sun, which causes it to curl into quills or sticks. These sticks are then cut and sold as cinnamon or ground into powder. The farmers also extract the essential oil from the cinnamon bark, which is used for aromatherapy, cosmetics, and perfumes.

​

Cinnamon cultivation in Meghalaya is not only a source of income, but also a way of preserving the traditional knowledge and culture of the people. Cinnamon is used in various ways by the local communities, such as for flavoring food and drinks, for treating various ailments, for making handicrafts, and for religious ceremonies. Cinnamon is also a symbol of hospitality and friendship, as it is often offered as a welcome drink or a gift to guests and visitors. Cinnamon is also a part of the indigenous folklore and legends, such as the story of U Suidnoh, a brave warrior who fought against the British invaders and used cinnamon as his weapon.

Medical Benefits of Cinnamon

Cinnamon has been used for its medicinal properties for thousands of years, as it may have various benefits for health. Some of the evidence-based health benefits of cinnamon are:

• Cinnamon may help lower blood sugar levels and improve insulin sensitivity, which can be beneficial for people with type 2 diabetes or prediabetes. Several studies have shown that cinnamon can reduce fasting blood sugar levels, postprandial blood sugar levels, and hemoglobin A1c levels, which are indicators of long-term blood sugar control. Cinnamon may also enhance the effects of some diabetes medications, such as metformin and sulfonylureas. However, people with diabetes or prediabetes should consult their doctor before taking cinnamon supplements or increasing their cinnamon intake, as it may interact with their medications or cause hypoglycemia (low blood sugar).

• Cinnamon may help protect against heart disease and stroke, which are the leading causes of death worldwide. Cinnamon may lower the risk factors for cardiovascular disease, such as high blood pressure, high cholesterol, and high triglycerides. Cinnamon may also prevent the oxidation of LDL (bad) cholesterol, which can cause plaque buildup and damage the arteries. Cinnamon may also improve blood circulation and prevent blood clots, which can reduce the chances of heart attack and stroke.

• Cinnamon may have anti-inflammatory properties, which can help reduce inflammation and pain in the body. Inflammation is a normal immune response to infection or injury, but chronic inflammation can lead to various diseases, such as arthritis, asthma, cancer, and Alzheimer’s disease. Cinnamon and its antioxidants may inhibit the production of inflammatory molecules, such as cytokines and prostaglandins, and modulate the activity of inflammatory cells, such as macrophages and neutrophils. Cinnamon may also relieve the symptoms of inflammatory conditions, such as joint pain, swelling, stiffness, and redness.

• Cinnamon may have antimicrobial, antifungal, and antiviral properties, which can help fight infections and boost immunity. Cinnamon may inhibit the growth and spread of bacteria, fungi, and viruses, such as Escherichia coli, Candida albicans, and influenza. Cinnamon may also enhance the function of the immune system, by stimulating the production of antibodies and natural killer cells, which can destroy the invading pathogens. Cinnamon may also prevent the formation of biofilms, which are colonies of microorganisms that can resist antibiotics and cause chronic infections.

• Cinnamon may have neuroprotective effects, which can help prevent or delay the onset of neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. Cinnamon may protect the brain cells from oxidative stress, inflammation, and toxicity, which can cause damage and death of the neurons. Cinnamon may also improve the cognitive function and memory of the brain, by enhancing the synaptic plasticity and the expression of neurotrophic factors, which are essential for the growth and survival of the neurons. Cinnamon may also prevent the accumulation of amyloid-beta plaques and tau tangles, which are the hallmarks of Alzheimer’s disease.

Downsides of Cinnamon

Cinnamon is generally safe and well-tolerated when consumed in moderate amounts as a spice or a supplement. However, cinnamon may also have some potential side effects and risks, especially if consumed in large amounts or in combination with certain medications. Some of the possible downsides of cinnamon are:

• Cinnamon may cause liver damage, especially if consumed in large amounts or by people with liver problems. This is mainly due to the high coumarin content of Cassia cinnamon, which can be toxic to the liver and cause liver failure or cancer. Ceylon cinnamon contains very low levels of coumarin and is safer for the liver. People with liver problems or who take liver-damaging medications, such as acetaminophen, should limit their intake of Cassia cinnamon or switch to Ceylon cinnamon.

• Cinnamon may interfere with blood clotting, especially if consumed in large amounts or by people who take blood-thinning medications, such as warfarin, aspirin, or clopidogrel. This is because cinnamon and its coumarin component may have anticoagulant effects, which can prevent the blood from clotting and increase the risk of bleeding and bruising. People who take blood-thinning medications or who have bleeding disorders should consult their doctor before taking cinnamon supplements or increasing their cinnamon intake.

• Cinnamon may cause allergic reactions, especially if consumed in large amounts or by people who are allergic or sensitive to cinnamon or other plants in the same family, such as birch, avocado, or banana. The symptoms of cinnamon allergy may include skin rash, itching, swelling, hives, difficulty breathing, nausea, vomiting, diarrhea, or anaphylaxis. People who are allergic or sensitive to cinnamon should avoid consuming it or contact their doctor if they have any symptoms of cinnamon allergy. Cinnamon allergy is rare, but it can be serious and life-threatening if not treated promptly.

• Cinnamon may cause digestive problems, especially if consumed in large amounts or by people who have gastrointestinal disorders, such as ulcers, gastritis, or irritable bowel syndrome. This is because cinnamon and its components may irritate the lining of the stomach and intestines, causing symptoms such as heartburn, indigestion, nausea, vomiting, diarrhea, or constipation. People who have gastrointestinal disorders or who experience digestive problems after consuming cinnamon should reduce their intake or avoid it altogether.

• Cinnamon may interact with certain medications, supplements, or herbs, which can alter their effectiveness or cause adverse effects. Some of the medications that may interact with cinnamon are antidiabetic drugs, blood thinners, antibiotics, antidepressants, anticonvulsants, and statins. Some of the supplements or herbs that may interact with cinnamon are chromium, ginseng, garlic, ginger, and turmeric. People who take any of these medications, supplements, or herbs should consult their doctor before taking cinnamon supplements or increasing their cinnamon intake.
