Dr. Michael Schink

About Dr. Michael Schink

Dr. rer. nat. Michael Schink, biologist including a focus on immunobiology, has decades of experience working with mistletoe therapy. Within the Medical Science Department at Helixor Heilmittel GmbH, he is responsible for all questions related to research and scientific issues of the company’s established medicinal products.

  1. Can I continue to receive mistletoe therapy during the COVID-19 pandemic?

    Yes. Especially now, cancer patients need to focus on boosting their overall well-being and strengthening their immune system. Mistletoe therapy supports both goals. I would absolutely recommend that patients either start mistletoe therapy or continue to receive a course of treatment at this time.

    Background: Cancer patients often have a weak or suppressed immune system. Given this fact, clinical studies have shown that mistletoe therapy not only significantly improves the quality of life of cancer patients and tolerability of conventional cancer therapies (1), but also leads to increased activity of natural killer cells (2, 3). The natural killer cells in our immune system are capable of detecting and destroying cancer cells or cells that have been invaded by pathogens.

  2. Will mistletoe therapy help prevent infection with COVID-19?

    No, it not suitable as a form of prevention. We cannot assume that mistletoe therapy provides general protection against a COVID-19 infection in otherwise healthy individuals.

    Background: Mistletoe therapy is indicated to stabilize the immune system in cancer patients. As a form of off-label use, some non-cancer patients who suffer from a weakened immune system also use mistletoe therapy (4). The objective in such cases is to treat an immunodeficiency and not to strengthen a normal immune system. In other words, mistletoe therapy does not stimulate the immune system but does help to balance existing deficiencies (5).

  3. Should I discontinue mistletoe therapy at the first sign of a cold?

    No, as long as there are no symptoms of an infection, mistletoe therapy may be continued.

    Background: However, as soon as acute inflammatory symptoms of a COVID-19 illness occur (e.g. fever, sore throat, cough, respiratory symptoms), contact your responsible health care provider immediately. He or she will decide whether to discontinue or proceed with therapy. Once inflammatory symptoms have fully subsided, mistletoe therapy can be resumed. Always stay in close (telephone) contact with your physician!

Dr. med. Xenia Wagner specializes in general medicine and is familiar with mistletoe therapy through experience in her own practice. Dr. Wagner is also a member of the Medical Advisory team at Helixor Heilmittel GmbH, providing practical advice to physicians, patients and family members.

  1. Do I need to visit a doctor to start mistletoe therapy?

    Yes, your physician will choose which type of mistletoe is best for your needs. During the first visit, you will also learn everything you need to know to safely and easily continue treatment at home.

    Background: To find the optimal therapy approach for your needs, your physician will base his or her decision on an initial personal examination and closely monitor the first injections. This make an in-person visit necessary. General practitioners are prepared to meet the special safety needs of high-risk patients in their practice. Talk to your health care provider about how he or she can address your specific needs!

  2. Can mistletoe therapy also help alleviate psychological stress?

    Yes, alongside physical symptoms, it often contributes to increased emotional well-being.

    Background: Mistletoe therapy improves the general condition of patients, especially symptoms such as fatigue or exhaustion, and helps with sleep, temperature, appetite and digestive disorders. Clinical studies on improving the quality of life of cancer patients receiving mistletoe therapy showed that many respondents mentioned a decrease in anxiety, an improvement in depressive moods, a more active lifestyle and a better ability to concentrate (1, 6).
