Mistletoe therapy, derived from the European mistletoe plant (Viscum album), has been used in integrative oncology for decades, especially across Europe. ABNOBA GmbH, based in Pforzheim, Germany, has been at the forefront of developing standardized mistletoe extracts for cancer support therapy. In India, ABNOBA India brings this evidence-based treatment option to patients seeking holistic cancer care.
While mistletoe therapy is generally considered safe and well-tolerated, like all medical treatments, it may cause side effects in certain individuals. Understanding these potential reactions helps patients and caregivers make informed decisions.
Common Side Effects of Mistletoe Therapy
-
Local Reactions at Injection Site
-
Redness, swelling, warmth, and mild pain are the most frequent side effects.

These are usually harmless and considered a sign that the immune system is responding to treatment.
-
They typically resolve on their own within 24–48 hours.
-
-
Fever and Flu-like Symptoms
-
Low-grade fever, chills, headache, and fatigue may occur, especially at the start of therapy.
-
These symptoms are temporary and often subside as the body adjusts.
-
-
Allergic Reactions
-
In rare cases, hypersensitivity reactions such as skin rash, itching, or difficulty breathing may occur.
-
Patients with known allergies should be closely monitored.

-
Low Blood Pressure and Dizziness

Some individuals may experience a drop in blood pressure leading to light-headedness.
-
This usually occurs with intravenous or higher doses.
-
Rare but Serious Side Effects
-
Severe Allergic Reactions (Anaphylaxis) – extremely rare but possible; requires immediate medical attention.

Inflammatory Reactions – in sensitive patients, mistletoe may trigger stronger immune responses, leading to discomfort.

Excessive Fever – high fever above 39°C can sometimes occur and should be reported to a doctor.
Safety Considerations
-
Individualized Dosing: Mistletoe therapy is highly individualized, and the dose must be adjusted according to the patient’s response.
-
Medical Supervision: It should always be administered under the guidance of trained healthcare professionals.
-
Not a Substitute for Cancer Treatment: Mistletoe therapy is used as a supportive treatment, not as a replacement for surgery, chemotherapy, or radiotherapy.
Conclusion
Mistletoe therapy, when administered properly, is generally safe and well-tolerated, offering immune modulation and quality-of-life improvements for many cancer patients. However, like any therapy, side effects are possible. Most are mild and temporary, while serious adverse reactions are rare. Patients considering mistletoe therapy in India through ABNOBA India should consult with their oncologist and a trained integrative medicine practitioner to ensure safe and effective use.
