This trial is testing a cinnamon supplement on healthy volunteers to see how it affects drug metabolism. Cinnamon contains cinnamaldehyde, which can deactivate an enzyme that breaks down drugs, potentially making them stay in the body longer. Cinnamon has been used for thousands of years around the world and has shown various therapeutic effects including antimicrobial, antiviral, antifungal, antioxidant, antitumor, antihypertensive, antilipemic, antidiabetic, gastroprotective, and immunomodulatory effects.
