Centaury Herb Extract

Processed by the liver

Watch for: Any medication that is also processed by liver enzymes (ask your pharmacist — this includes many common prescriptions)

Can alter how quickly the body clears certain medications, raising or lowering their effective dose.

May affect blood sugar

Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)

Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.

Watch for: Diuretic medications and lithium

Additive fluid loss can affect electrolyte balance and change how the body clears lithium.
