Turmeric root extract contains curcuminoids, a mixture of diferuloymethane derivatives that gives it its yellow pigment.
Topical application of curcuminoids to the human skin is joined by orange-yellow discoloration.
We describe a patient in which a yellow discoloration of the soles is attributed to the oral consumption of a 500 mg capsule of turmeric root extract daily, for 4 months. A Naranjo assessment score of 5 indicates a probable relationship between the patient’s symptom and her use of the drug.
