Cinnamon and cassia nomenclature confusion: a challenge to the applicability of clinical data.
Maierean SM, Serban M-C, Sahebkar A, et al.Use in larger amounts or for long periods of time is sometimes associated with side effects, most commonly gastrointestinal problems or allergic reactions. Cinnamon: a systematic review of adverse events. What Do We Know About Safety Cinnamon supplements appear to be safe when consumed in the amounts commonly used in foods as a spice or flavoring agent. Hajimonfarednejad M, Ostovar M, Raee MJ, et al.Journal of the Academy of Nutrition and Dietetics. Do cinnamon supplements have a role in glycemic control in type 2 diabetes? A narrative review. Costello RB, Dwyer JT, Saldanha L, et al.International Journal of Food Sciences and Nutrition. Bioactivity of cinnamon with special emphasis on diabetes mellitus: a review. This is particularly true if you have diabetes. Cinnamon should not be used in place of conventional medical care or to delay seeking care if you have health problems.Little is known about whether it’s safe to use Ceylon cinnamon during breastfeeding in amounts greater than those commonly found in foods. Ceylon cinnamon may be unsafe for use during pregnancy if consumed in amounts greater than those commonly found in foods. Little is known about whether it’s safe to use cassia cinnamon during pregnancy or while breastfeeding.However, prolonged use of cassia cinnamon could be an issue for sensitive people, such as those with liver disease. In most cases, consuming cassia cinnamon doesn’t provide enough coumarin to cause significant problems. Some cassia cinnamon products contain high levels of this substance. Cassia cinnamon contains a chemical called coumarin, which can be harmful to the liver.Cinnamon supplements appear to be safe when consumed in the amounts commonly used in foods as a spice or flavoring agent.The doctor may need to consult a reference to find out if the medications he has prescribed are metabolized by CYP 2A6, 2D6 or 3A4. Your husband should ask his doctor to check whether cinnamon would pose a problem with his other drugs.
We don’t have any studies that show whether there truly are interactions between cinnamon and medications metabolized by these enzymes. We trust, however, that your husband is not smoking cigarettes or chewing nicotine gum. This agent inhibits the enzyme CYP 2A6 and consequently can interfere with the metabolism of nicotine ( Drug Metabolism & Disposition, April 2016). Other Possible Interactions:Īnother compound found in cinnamon is cinnamaldehyde. CYP 2D6 is critical for metabolizing the blood pressure medicine metoprolol. Certain drugs such as amlodipine, diltiazem, felodipine isradipine, nicardipine and nifedipine might be affected because they are metabolized through CYP 3A4. As a result, it might theoretically interact with the anticoagulant warfarin as well as with a number of blood pressure medications. (Although it sounds like Coumadin, it isn’t at all the same compound.) Some people are susceptible to liver damage if they take too much of this spice.Ĭoumarin affects drug metabolizing enzymes CYP 2D6 and 3A4. The trouble is that the most common form in the supermarket is cassia cinnamon, which often contains a compound called coumarin. Cinnamon might also help normalize cholesterol levels and reduce joint inflammation. People with type 2 diabetes may use it to help control blood sugar ( Annals of Family Medicine, Sept/Oct, 2013 Endotext, March 4, 2014). Cinnamon has become very popular for its medicinal properties. Does he need to discuss this with his doctor? We don’t want to create a problem by taking the honey and cinnamon mixture.Ī.
He also has hypertension and takes medication for that.
We recently began taking a mixture of honey and cinnamon. My husband takes Coumadin (warfarin) for atrial fibrillation. One reader had a relevant question about interactions between cinnamon and medications: Does Cinnamon Interact with Coumadin? Unfortunately, it can be far more difficult to learn about interactions between drugs and supplements. That is just as important for those taking dietary supplements. We often warn patients to be aware of potential interactions among the different medicines they take.
