Recent research suggests that consuming large amounts of cinnamon, particularly as a supplement, may interfere with certain prescription medications. This finding was detailed in a study published in the June issue of The Food Chemistry: Molecular Sciences Journal, which looked into how cinnamon and its main components affect the body’s drug metabolism.
The study explores concerns regarding the possible interactions between cinnamon and various medications, highlighting a gap in scientific understanding about how spices impact human metabolism. While small amounts of cinnamon could be beneficial for health, increasing its intake raises the risk of drug interactions, although the research doesn’t clarify what constitutes excessive use.
Experts indicate that consuming too much cinnamon can rapidly eliminate prescription drugs from the body, hindering absorption. Bill Gurley, a lead scientist at the University of Mississippi’s Center for Natural Materials Research, noted that cinnamaldehyde can activate certain receptors, posing a risk for drug interactions.
The research involved testing cinnamon oil and its chemical components—cinnamaldehyde and cinnamic acid—through simulated human digestion to determine their effects on drug metabolism. Findings revealed that these compounds can activate the body’s xenobiotic receptors, which play a crucial role in drug processing.
Dr. Leana Wen, a wellness expert, mentioned that while some studies indicate cinnamon can aid in diabetes management and weight loss, more investigation is essential to understand its full benefits. Furthermore, Cassia cinnamon might have high levels of coumarin, a compound that can thin the blood, with even Ceylon cinnamon containing trace amounts of it.
Individuals on anticoagulant medications might face a greater risk of bleeding if they consume significant amounts of coumarin. The food chemistry studies didn’t quantify this risk, but researchers cautioned that concentrated forms like supplements can be more harmful. Therefore, it’s advisable for patients to consult with their healthcare providers before using cinnamon supplements or related products.
