Abstract
A 61-year-old woman with depression developed recurring elevated itching erythematous lesions in light-exposed areas after taking St. John's Wort-extract for three years. Routine patchtesting did not reveal any relevant reactions and photopatch testing was negative. Using a systemic oral photoprovocation test with St. John's Wort, we were able to demonstrate a decrease of the MED-UVB which was reversible after withdrawal of the medication.
