Rudolf Steiner on cancer and mistletoe-

Cancer can grow where the vital force withdraws from the physical and leaves a “void”, “… mistletoe counteracts this "void” and draws the etheric forces again to the area which they do not want to
Mistletoe provides, beyond question, a means which - when given in potencies - should enable us to dispense with the surgical removal of tumors. The point is only to find out how to treat the mistletoe fruit in combining it with other forces of the mistletoe plant, in order to arrive at a remedy.”
-Rudolf Steiner, Spiritual Science and Medicine, Lecture XIII, 4/20/1920

Modern science has reaffirmed the therapeutic importance of mistletoe, through identification of the viscotoxins (literally, "mistletoe toxins"), lectins, and alkaloids thought to be responsible for its anticancer and immune modifying activities. Presently 60% of all cancer patients in Germany and Switzerland are prescribed mistletoe at some point in their treatment.

Licensed medical prescribers seeking more information and training in the use of mistletoe are invited to register for the Best Practices Mistletoe Course, happening in Baltimore, Maryland, June 21-23, 2019.

The mistletoe family contains more than 1000 species, however, anticancer drugs are derived solely from viscum album (common or European mistletoe). Viscum album occurs across a small number of host-trees. The host trees are: apple (mali), pine (pini), fir (abietis), oak (quercus), hawthorn (crataegus), ash (fraxini), elm (ulmi),  and poplar (populi).

There are currently four main European mistletoe producers:
Iscador by Iscador AG (from 5 host trees)
Helixor Viscum by Helixor (from 3 host trees)
Iscucin by WALA (from 8 host trees)
Abnoba Viscum by Abnoba (from 5 host trees)

Mistletoe is especially interesting botanically because it is a partial parasite (a "hemiparasite").
As a parasitic plant, it grows on the branches or trunk of a tree and actually sends out roots that
penetrate into the tree and take up nutrients. But mistletoe is also capable for growing on its own;
like other plants it can produce its own food by photosynthesis.

Mistletoe (viscum album) is listed in the Homeopathic Pharmacopeia of the United States (HPUS). Homeopathic remedies are regulated as drugs under the Federal Food, Drug and Cosmetic Act (FDCA).

If you are a patient seeking more information about mistletoe, or if you are a physician seeking more information about mistletoe, please see our Provider Directory for a state-by-state listing of MDs, DOs, NPs and PAs who may be able to provide information on mistletoe research. MISTLETOE IS NOT APPROVED BY THE FDA FOR CANCER TREATMENT.
