Many herbal supplements and remedies have been touted as remedies for hypertension, cinnamon among them. However, in the case of cinnamon no conclusive evidence exists to prove it effective at lowering blood pressure. Hypertension is a serious condition that increases your risk for heart attack and stroke. Do not self-treat with cinnamon or other herbal remedies unless under the care of a doctor.
How It Works
Most documented medicinal effects of cinnamon relate how it affects blood sugar levels in people with type 2 diabetes, where it may help control blood sugar levels, MedlinePlus reports. However, even in this regard research has demonstrated conflicting results and it has not been proven effective. Its positive effects of high blood pressure have never been clinically proven, MedlinePlus reports, meaning it may have no effect on hypertension. Because of the seriousness of the condition, you should never use cinnamon to lower blood pressure unless you have first consulted with a doctor.
Dosage Recommendations
No specific dosing recommendation exists when using cinnamon to lower blood pressure because it has not been thoroughly studied. In general, recommended doses for the supplement range from 1 g to 4 g daily for ground cinnamon bark or 0.05 g to 0.2 g daily of cinnamon oil, the Langone Medical Center reports. Before you take a cinnamon supplement to treat any medical condition, you should consult with a doctor who can recommend a dose that is safe for you. Also, always carefully read the label directions for your supplement to ensure you use it properly.
Side Effects
Most people tolerate cinnamon without side effects when used in medicinal quantities. However, some experience side effects such as skin rashes when the oil is applied topically. Others develop bronchial constriction from use of the supplement, and it can also cause allergic skin reactions, the University of Michigan Health System reports. Also, long-term oral use of concentrated cinnamon oil can cause irritation of the mouth. Always discuss your use of cinnamon oil with your doctor so you understand what to expect.
Warnings and Precautions
Cinnamon contains a chemical compound called coumarin, and in people sensitive to the substance it can cause liver disease or worsen the condition, MedlinePlus reports. And because it can affect blood sugar levels people with diabetes should only use it under the direction of a doctor. For the same reason, you should not use cinnamon if you are scheduled to undergo surgery. Finally, the safety of cinnamon has not yet been studied in women who are pregnant or breastfeeding. Do not take cinnamon supplements unless you have talked with a doctor familiar with your medical history who can determine whether it is safe for you.
