Phytophotodermatitis, also known as berloque dermatitis, [1] [2] [3] margarita photodermatitis, [4] [5] lime disease [6] or lime phytodermatitis [6] is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent (such as lime juice) followed by exposure to ultraviolet A (UV-A) light (from the sun ...
Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure.
The rash appears immediately in irritant contact dermatitis; in allergic contact dermatitis, the rash sometimes does not appear until 24–72 hours after exposure to the allergen. Blisters or wheals: Blisters, wheals (welts), and urticaria (hives) often form in a pattern where skin was directly exposed to the allergen or irritant.

The sap of the giant hogweed plant is phototoxic. The sap contains furanocoumarins, which leads to phytophotodermatitis, a serious skin inflammation. [40] A phototoxic reaction can begin as soon as 15 minutes after contact with the sap. Photosensitivity peaks between 30 minutes and two hours after contact but can last for several days.
Both plants are found in parts of the United States, and their sap, “in combo with moisture and sun,” can cause irritation, burning and scarring if touched.
