Systemic photosensitivity due to the intake of plants or herbal compounds is a rare phenomenon. Goji berries are widely used as a well‐being and anti‐aging remedy. In spite of this, only a few adverse reactions and no cases of photosensitivity have been reported to date. A 53‐year‐old male consulted due to a pruriginous eruption located on sun‐exposed areas of 2 weeks of duration. He had been taking Goji berries and infusions of cat's claw herb for 5 and 3 months, respectively. Minimal erythema dose for UVB (MED‐UVB) was diminished when the patient was taking these products, and became normal when they were withdrawn. Photoprovocation tests with Goji berries and cat's claw were performed. MED‐UVB decreased after the intake of Goji berries, and was normal with cat's claw. We report the first case of systemic photosensitivity due to Goji berries.
