Certain alternative medicines can do more harm than good, according to panelist Prateeti Khazanie, MD, who specializes in advanced heart failure and transplant cardiology at the UCHealth Heart Failure Clinic at the Anschutz Medical Campus in Colorado. Dr. Khazanie shared the story of a patient who was drinking herbal tea, which happened to contain a lot of licorice root. Too much licorice can lower a person’s potassium levels and disrupt normal heart function.
