Title: Research Highlights Need for Caution: Cinnamon’s Health Benefits and Potential Drug Interactions
A new study from the University of Mississippi’s National Center for Natural Products Research provides crucial insights for consumers, highlighting both the potential health benefits of cinnamon and the importance of consulting a healthcare provider before using it as a supplement, especially for individuals on prescription medications.
The Dual Nature of a Common Spice
While renowned for its culinary uses and a long history in traditional medicine for aiding blood sugar management, heart health, and reducing inflammation, the precise mechanisms of how cinnamon works within the body have remained unclear. This new research delves into those mechanics, uncovering a significant consideration for public health.
Understanding the Mechanism
The study identifies that cinnamaldehyde, a primary component of cinnamon, activates receptors that control the body’s metabolic clearance of drugs. Lead scientist Shabana Khan explains, “If a large amount of cinnamon is consumed without informing the physician or the person who is prescribing the drugs, it might cause some health problems.” Excessive supplementation could lead to the rapid clearance of a prescribed drug from the body, potentially reducing the medication’s effectiveness.
Not All Cinnamon is Created Equal
The research further distinguishes between different types of cinnamon, a critical factor for risk assessment.
- Cassia Cinnamon: This more common and affordable variety, typically found ground in grocery stores, originates from Southern China. It contains significant amounts of coumarin, a known blood-thinning agent. Its anticoagulant properties can be dangerous for individuals already taking blood-thinning medication.
- Ceylon Cinnamon: Often referred to as “true” cinnamon from Sri Lanka, this variety presents a lower risk due to its substantially reduced coumarin content.
The study notes that cinnamon oil, used topically or as a flavoring, carries almost no risk of botanical-drug interactions.
A Call for Further Research and Professional Consultation
Bill Gurley, a senior scientist and study co-author, emphasized that more research is needed to fully understand cinnamon’s role in the body and its potential drug interactions. “We know cinnamaldehyde has the potential to activate these receptors, which could create a risk for drug interactions. This is something that could happen, but until we do a clinical study, we won’t know exactly what will happen.”
Until such studies are complete, the researchers’ primary recommendation is clear: individuals interested in using cinnamon as a dietary supplement, particularly those managing chronic conditions such as hypertension, diabetes, or heart disease, should first consult their physician.
“The best advice we can give,” concludes Khan, “is to talk to a doctor before using any supplement alongside a prescription drug.” This guidance ensures that the pursuit of natural health benefits does not inadvertently compromise the efficacy of essential medical treatments.
