Most people are familiar with mistletoe as the plant we kiss under during the Christmas holidays, but did you know that mistletoe also has important medicinal properties? Its historical use can be traced back more than 2,000 years. [1] The ancient Greeks and Romans used mistletoe to treat a wide variety of health issues.

Research on Mistletoe

Mistletoe is the plant name given to many hemiparasitic plants. The various mistletoe species differ in their therapeutic actions, toxicities, and geographic locations.

There are nearly 100 species of mistletoe, which all fall in the genus Viscum and several types of Viscum have undergone rigorous scientific testing, which is especially true as it relates to cancer.

Viscum use for cancer is mentioned in the literate starting in the early 1900s. Dr. Ita Wegman around 1920 first developed its use as an injectable agent for cancer. Research has subsequently shown that Viscum has several notable effects.

First and foremost, Viscum is like an immune system enhancing therapy. It exerts its immune effects through various mechanisms, including:

  • Increase in the number of immune system cells [2]
  • and activity of immune system cells [3]
  • Increase in the activity of various cytokines, including IL-1, IL-2, IL-6, interferon-g, and tumor necrosis factor-a
  • Increase in body temperature


Viscum also has a cytotoxic (cancer cell-killing) effect through its inhibition of protein synthesis. [4] By blocking the production of specific proteins, cancer cell death via apoptosis ensues.

Also, Viscum has an anti-cancer effect — it inhibits angiogenesis, which is the production of new blood vessels. In the setting of cancer, new blood vessels are used to assist cancer in its growth and spread.

Perhaps as a result of its noted anti-cancer effects, mistletoe has been shown to improve quality of life. [5] Reductions in pain, diarrhea, nausea, vomiting, and insomnia have been seen in mistletoe studies.

Finally, mistletoe has been shown to be compatible with many chemotherapeutic agents, resulting in no negative herb-drug interactions. [6] This compatibility was shown to exist even when chemotherapy and Viscum were given simultaneously.

Due to its extensive clinical use worldwide for many years, coupled with solid scientific research supporting its use, we believe that mistletoe is a vital component in most integrative cancer treatment protocols.

What is Integrative Oncology?

There are many approaches to treating cancer. The Center for Advanced Medicine believes integrative oncology combines the best aspects of two seemingly contradictory branches of medicine.

Nutrition and Cancer

There are now many scientific studies that show nutrition does make a difference in cancer treatment and prevention. By practicing integrative oncology, we make room for the importance of nutrition in any cancer treatment plan.

Giving Back

Our founder and medical director, Dr. Jonathan Stegall, feels strongly that he has a responsibility, as a physician and a Christian, to give back. He not only wants to leave a legacy of hope and healing to his patients but also to the world around him.
