Strong Medicine

Dr. Campbell is asked to write an endorsement for a new book about female heart health written by a friend and patient. After the author dies of a heart attack, her husband refuses to publically announce her cause of death because he fears it would hurt sales of the book even though her diet had nothing to do with her death (she had heart disease). Lu is shocked when three high school girls come into the ER with similar and shocking symptoms that point towards poisoning.
