Mistletoe

Extracts of Mistletoe extracts (Viscum album) are widely used in Europe as a component of complementary treatment of cancer.1  Its use began in 1920, and since that time there have been a number of studies of its effectiveness against tumors in plants, animals, and humans.

Pharmacologically active compounds include mistletoe lectins (ML I, II and III), viscotoxins, oligo- and poly- saccharides, and lipophilic extracts.  These exert their effect through two mechanisms—direct and immune-mediated.  Direct cytotoxic effects are due to the apoptosis-inducing mistletoe lectins, and viscotoxin induction of necrotic cell death.  Immune-modulating activity involves activation of onocytes/macrophages, granulocytes, natural killer (NK) cells, T-cells (especially T-helper-cells) and the induction of various cytokines.2

Clinical effectiveness of mistletoe extracts in the treatment of oncological disease has been widely studied, although many published studies have been of small size or lacked randomized controlled design.  A 2011 review of 20 clinical trials of use of mistletoe in cancer found some with evidence of increased survival, some without survival impact, and most with improvement in quality of life—well-being or reduction in chemotherapy side effects.  None showed any adverse impact on chemotherapy.3  A 2013 randomized study found increased duration of survival in patients with metastatic pancreatic cancer (4.8 v 2.7 months).4

Mistletoe is used clinically through subcutaneous injection or IV infusion of
a fermented extract made from the leaves and berries of the plant.

Although approved in a number of European countries, it has not been
approved for use in the United States by the FDA.

At Integrative Health Practices, we offer mistletoe therapy to patients with
cancer who are seeking potential improvement in quality of life.  Patients
receive an initial exam by an integrative physician or physician assistant,
and an integrative treatment plan is developed.  Patients are taught to self-
administer it beginning on a low dose via subcutaneous injection, with
increasing doses to a point at which local immune response is
demonstrated, following which maintenance injections are provided. Some
patients who have successfully begun self-injections add weekly IV
mistletoe infusions to their regimen.

Patients receiving mistletoe therapy pay our concierge fee and for their first package of the injection solution. Encounters with the physician/PA are billed to insurance.  IV mistletoe infusions are not covered by insurance and payment is required at the time of service.
