Mistletoe Therapy: A Natural, Integrative Treatment in the Cancer Journey

When facing a cancer diagnosis, exploring every option that might support your well-being alongside conventional treatments is a natural and empowering step. One important integrative therapy, with both a long-standing historical foundation and strong scientific support, is Mistletoe therapy. Dr. Colin Race explains:

Mistletoe therapy has developed into a sophisticated complementary treatment used by physicians across Europe and North America. It is most commonly administered under the skin (subcutaneously), though in certain cases it may also be given directly into the bloodstream (intravenously), depending on individual needs and treatment goals.

A Long and Trusted History

Mistletoe’s formal introduction into cancer care began in the 1920s, and it has since become one of the most well-researched natural therapies in oncology.

To date, over 2,000 scientific publications and 130 clinical studies have examined mistletoe’s effects, including more than 40 prospective-randomized clinical trials. HELIXOR® mistletoe extracts (sold as VISCOSAN® in Canada) have been safely used since 1975, with decades of clinical experience supporting their continuing use today.

Why Consider Mistletoe Alongside Conventional Cancer Care?

Mistletoe therapy is particularly valuable alongside chemotherapy and radiation, as it has the potential to:

– Enhance treatment effectiveness, potentially making cancer cells more responsive to chemotherapy and radiation without adding toxicity

– Improve treatment tolerance by reducing side effects like fatigue, anemia, low white blood cell counts, and thrombocytopenia

– Protects the immune system from chemotherapy-induced immunosuppression

In addition to these benefits, many patients report a broad improvement in their sense of daily well-being and quality of life (QOL). These include:

– Better energy levels

– Improved sleep and appetite

– Reduced nausea and cancer-related pain

– Greater physical and emotional resilience

Mistletoe also acts directly on cancer cells, inducing apoptosis (programmed cell death) and helping to inhibit tumor growth. Its immune-activating properties further assist your body in identifying and attacking cancer cells, offering the potential for improved outcomes and increased survival.

Subcutaneous (SQ) Mistletoe Therapy: A Simple and Accessible Approach

Subcutaneous mistletoe therapy involves injecting the extract just under the skin and is commonly used for long-term support and maintenance. It is typically self-administered at home several times per week and allows for ongoing immune stimulation throughout the treatment process.

This method is well-tolerated, convenient, and effective for many patients, and offers a consistent foundation for immune support and symptom relief. Some individuals may remain on subcutaneous therapy for months or even years, depending on their diagnosis and response.

Intravenous (IV) Mistletoe Therapy: A Targeted and Potent Option

In some cases, especially where a stronger therapeutic effect is desired, or in more advanced illness, mistletoe may be administered intravenously. IV mistletoe delivers the extract directly into the bloodstream and can lead to an increased immune activation and a greater inhibitory effect on cancer cell growth.

This approach is typically used when:

– Additional support is needed during or after intensive treatments

– There is a need to improve tolerance to chemotherapy or radiation

– Faster symptom relief or immune stimulation is required

IV mistletoe is often given twice weekly, with the dose gradually increased based on how the body responds. It is also commonly paired with intravenous Vitamin C therapy, which may enhance the immune and anti-tumor effects of mistletoe while also supporting antioxidant status and reducing inflammation.

Patients receiving IV mistletoe are monitored closely, and many report improvements in energy, appetite, sleep, and overall quality of life, like those seen with subcutaneous therapy, often with added benefit.

To Conclude

Mistletoe therapy represents a powerful integration of nature and science, offering cancer patients support that goes beyond symptom relief. With decades of use, robust clinical research, and a strong safety profile, mistletoe therapy can be a meaningful addition to conventional cancer care.

If you are exploring options to strengthen your body, support your treatment, and improve your quality of life, mistletoe therapy may be worth considering as part of your integrative care plan.

Always speak with a licensed and experienced practitioner to determine if mistletoe therapy is appropriate for you. In Canada, injectable use of VISCOSAN® (HELIXOR®) is considered off-label and must be administered by qualified professionals.
