We report the case of a man with chronic renal insufficiency who self-medicated with an alternative medicine product known as noni juice (Morinda citrifolia). The patient presented to the clinic with hyperkalemia despite claiming adherence to a low-potassium diet. The potassium concentration in noni juice samples was determined and found to be 56.3 mEq/L, similar to that in orange juice and tomato juice. Herbal remedies and alternative medicine products may be surreptitious sources of potassium in patients with renal disease.
