Prepared by: Ms. Tabarak Ahmed Turki Al-Azzawi<br />Introduction:<br />Cinnamon is one of the most well-known medicinal herbs, renowned for its antioxidant and anti-inflammatory properties for thousands of years. In recent years, there has been growing interest in the effects of cinnamon on kidney health, particularly among individuals suffering from chronic diseases such as diabetes and hypertension—two major contributing factors to the development of kidney disease.<br />1. Antioxidant and Anti-inflammatory Effects:<br />Cinnamon contains potent compounds such as cinnamaldehyde and coumaric acid, which have demonstrated strong antioxidant properties in reducing oxidative stress in kidney tissues. This role is crucial in protecting against cellular damage caused by chronic inflammation or elevated blood glucose levels.<br />2. Regulation of Blood Sugar Levels:<br />Cinnamon has been found to improve insulin sensitivity, thereby reducing the burden on the kidneys, especially in individuals with type 2 diabetes, where kidneys are constantly under stress due to high glucose concentrations.<br />3. Blood Pressure Reduction:<br />Evidence suggests that regular consumption of cinnamon may contribute to lowering both systolic and diastolic blood pressure. This is considered a protective factor for the kidneys, as prolonged hypertension can lead to damage in the renal blood vessels and deterioration of kidney function over time.<br />4. Antimicrobial Activity:<br />Cinnamon possesses natural antimicrobial properties, making it beneficial in preventing urinary tract infections (UTIs), which, if left untreated, may reach the kidneys and cause further complications.<br />5. Animal and Experimental Studies:<br />In experimental studies conducted on animal models with partial kidney failure, the use of cinnamon extract was observed to improve several renal biomarkers such as creatinine and urea levels in the blood. These findings support the potential role of cinnamon as an adjunct in protecting kidney function.<br />Warnings and Precautions:<br />Despite its potential benefits, excessive consumption of cinnamon—especially the commercial variety rich in coumarin—may lead to hepatic or renal toxicity with prolonged and high-dose use. Therefore, moderate intake is recommended, and individuals with chronic illnesses should consult their physician before incorporating cinnamon into their daily regimen.<br />Conclusion:<br />Cinnamon shows promising properties in supporting kidney health through its roles in antioxidant defense, blood sugar regulation, and blood pressure control. However, more extensive clinical studies are required to <br />confirm its effectiveness and safety, particularly in patients with kidney disease.<br /><br />Al-Mustaqbal University ، The First University in Iraq
