A senior pharmaceutical expert has cautioned individuals on the potential interactions between some commonly used spices and prescription medications. Dipa Kamdar, Senior Lecturer in Pharmacy Practice at Kingston University, highlights that spices such as cinnamon, turmeric, and ginger have long been celebrated for their health-promoting properties, including reducing inflammation, regulating blood sugar, and supporting brain and heart health.
Historically utilized in traditional Ayurvedic and Chinese medicine, these spices contain powerful compounds that can influence how medications work in the body. Kamdar explains, “Spices have been more than just flavor enhancers — they possess bioactive ingredients that may affect drug metabolism and efficacy.”
Cinnamon, for example, contains compounds like cinnamaldehyde, eugenol, and coumarin. While prized for its antioxidant properties and ability to aid digestion and blood sugar regulation, recent studies suggest cinnamon may accelerate the clearance of certain drugs from the body, potentially reducing their effectiveness. High doses, especially in supplement form, may also raise bleeding risks when combined with anticoagulants such as warfarin due to coumarin’s effect on liver enzymes.

Turmeric’s active ingredient, curcumin, is known for anti-inflammatory and antioxidant effects. However, its interaction with medications remains less studied. Evidence indicates curcumin may influence how the body metabolizes drugs like antidepressants, blood pressure medications, chemotherapy drugs, and antibiotics. Additionally, turmeric’s natural blood-thinning and blood sugar-lowering properties could intensify the effects of related medications, sometimes causing excessive drops in blood pressure or blood sugar.
Ginger, widely recognized for easing nausea and inflammation, contains compounds like gingerol that may alter drug metabolism. It can act as a mild blood thinner, increasing bleeding risk when paired with anticoagulants. Research on its effect on blood sugar is mixed, warranting caution for those on diabetes treatments.
Ms. Kamdar advises patients taking blood thinners, diabetes medications, or chemotherapy drugs to consult healthcare professionals before incorporating high-dose herbal supplements. Nevertheless, she emphasizes that typical culinary use of these spices is generally safe and offers flavorful health benefits. “Sprinkle, pinch, or dash away—just be mindful of your medications and avoid excessive supplement doses,” she concludes.
