Drugs such as ephedra, bitter orange, and chitosan have raised concerns related to health problems, liver damage, and thermogenic effects.
Ephedra and bitter orange can have negative effects on appetite, blood pressure, heart rate, and mental health. Chitosan is associated with increased risk of stroke or heart attack, blood clots, and various types of cancer.
