We present a case of exogenous Cushing syndrome caused by Binahong: an over-the-counter 'herbal' supplement. A 54-year-old woman presented with weight gain, joint pain, hypertension and poorly regulated type 2 diabetes mellitus despite the start of semaglutide one year before presentation. Physical examination revealed signs of steroid excess with a moon face and abdominal obesity. Her serum cortisol level and ACTH level were suppressed. Synthetic glucocorticoid screening revealed a positive dexamethason level in the herbal supplement. After stopping the supplement her serum cortisol and dexamethason increased to normal levels. This case emphasizes the importance of awareness for the use of supplements containing hidden glucocorticoids causing Cushing syndrome.
