Viscum album, or European Mistletoe, has been used for centuries to treat headaches, seizures, and other conditions. In modern-day Europe, Viscum album is used to treat cancer. Extracts are taken from the leafy outshoots and berries of Viscum album and the extracts are taken by mouth. Some extracts are available as injections by prescription in Europe, but these injections are not available in the United States. Lab tests have indicated that Viscum album extract kills cancer cells and boosts the immune system. Both European and American Mistletoe are poisonous when eaten raw, and American Mistletoe is unsafe for medicinal use. Viscum album, or European Mistletoe, is generally considered safe once it has been processed for human consumption.

A parasitic shrub grown in Central and Southern Europe. The viscid berries are a source of birdlime. Historically used a treatment for epilepsy amongst the Romans. Used in China (viscum coloratum) medicinally for hypertension, rheumatic fever, spontaneous abortion, epilepsy, hysteria, and neuritis. Prescribed as antiphlogistic, antispasmodic, carminative, sedative and is currently being developed for coronary problems. Proteins known as viscotoxins are cytotoxic and show anticancer activity in animals. Natural occurring GABA causes hypotensive activity and there are several antiinflammatory triterpernes.

This may explain why Mistletoe is synergistic with the action of Hawthorn, acting upon the cardiovascular system. It is known to lower blood pressure while also preventing calcium from being deposited pathologically on the walls of arteries and veins, thus aiding in the prevention of hardening of the arteries. Mistletoe is thought to help veins and arteries which have already become calcified to become more elastic and flexible, and thus is an excellent addition to any oral chelation formula. And too, because of this unique quality of preventing calcium from becoming pathological, it is useful in the prevention of gall and kidneys stones.
