The case report of an 81-year-old Chinese American woman taking nonprescribed, over-the-counter, dietary herbal supplements is presented to demonstrate the risk of undisclosed use of supplements. This article emphasizes the need for registered dietitian nutritionists and other health care professionals to encourage patients disclose their use of dietary supplements and conduct evaluations on potential adverse herb-drug interactions. Recommendations should be provided to patients regarding the use of dietary supplements as part of the comprehensive patient care. © 2017 Wolters Kluwer Health, Inc. All rights reserved.
