title: Systemic photosensitivity due to Goji berries.
abstract: 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dose for UVB (MED-UVB) was diminished when the patient was taking these products, and became normal when they were withdrawn.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.
