Carmine (Carmine red), a "semi-synthetic" dye, is a complex of aluminum and the natural dye Cochineal (Carminic acid). Cochineal is isolated from the native Mexican and South American insect. Carmine is a widely used "natural" food additive. Carmine provokes both an immediate hypersensitivity and a delayed systemic response with cutaneous expression[1][2].
