RESUMO
Mistletoe (Viscum album) is a plant that is semiparasitic of several trees: apple, oak, pine trees, etc. Because of the probable cytolytic action of one of the leaf's most abundant composites, in some countries mistletoe is used as a complementary medicine. Although only a few adverse reactions have been noted (cephalea, fever), cases of anaphylactic shock have been described. We present three cases of severe reaction after injection of mistletoe extract. Two of the patients had cancer. The third, whose brother had cancer, used the plant for preventive purposes. We discuss the danger of possible severe reactions due to the use of products employed in so-called alternative therapies.

El Mistletoe (Viscum album) (muérdago o visco blanco) es una planta semiparásita de algunos árboles: manzano, roble, pino, etc., que por la probable acción citolítica de algún compuesto más abundante en las hojas, se emplea en algunos países en el tratamiento del cáncer como medicación complementaria. Aunque se han observado pocas reacciones adversas (cefalea, fiebre) se han descrito casos de choque anafiláctico. En este trabajo se presentan tres casos de reacción grave, tras la inyección de un extracto de la planta. Dos pacientes padecían cáncer y otro empleó el producto por prevención por el N hecho de que un hermano padecía cáncer. Se advierte de las posibles reacciones graves por el uso de productos utilizados en las llamadas terapias alternativas (AU)
