Cinnamon contains a compound called coumarin, which in high doses can cause liver damage or affect the metabolism of certain medications.
Although its moderate use can be beneficial, consuming it in excess or in concentrated capsules can lead to complications, especially in people with chronic diseases or continuous treatments.
Other condiments that deserve attention
Ginger: useful, but with limits
Ginger helps improve digestion and can promote insulin sensitivity, but if combined with diabetes medications it can cause dangerous sugar crashes. Ideally, use it in small amounts and not as a substitute for medical treatment.
Turmeric: powerful, yet interactive
Turmeric is known for its anti-inflammatory and antioxidant effect, but it can interfere with blood thinners, blood pressure medication, or drugs that are metabolized in the liver. Its use must be prudent and always accompanied by professional monitoring.
