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 enter…
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.

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)

There is also currently one North American mistletoe producer in the Anthroposophic method:
Viscum album by Uriel Pharmacy (from 8 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 mistletoe therapy,  or if you are a physician seeking more information on providing mistletoe therapy, please see our Provider Directory for a state-by-state listing of MDs, DOs, NPs and PAs who may have training and experience in mistletoe therapy. Inclusion on the Directory does not necessarily mean that the listed individual is trained or experienced in mistletoe therapy; such information would need to be gained by contacting the doctor's  office directly.

If you are a licensed medical prescriber (MD, DO, ND, NP or PA) interested in training in prescribing mistletoe therapy, please write to us at
