Twenty one million dollars worth of bitter orange was sold last year on the promise that it can boost weight loss or relieve allergies. However, this supplement can cause heart attack, stroke or even death. Bitter orange contains a stimulant similar to ephedrine, banned by the FDA in 2004 after two people died and several suffered heart attacks or strokes. This was the first time the FDA banned an herbal supplement, and bitter orange has many similar chemical properties.
Keep in mind: It is important to remember to exercise caution when taking any form of supplement. Make sure to read labels carefully and discuss with your doctor, especially if you are already taking any prescription medications.
