Interactions with Supplements, Foods, & Other Compounds
Decoctions of bitter orange substantially increased blood levels of cyclosporine in pigs, causing toxicity.21 Bitter orange also inhibited human cytochrome P450 3A (CYP3A) in the test tube.22 This is an enzyme that helps the liver get rid of numerous toxins, and strongly affects metabolism of certain drugs. Bitter orange might, therefore, interact with drugs that are metabolized by CYP3A. To be on the safe side, bitter orange should not be combined with prescription medications, unless someone is under the care of an experienced natural medicine clinician.
