European Mistletoe

How does European Mistletoe work?

European mistletoe has several active chemicals. It might stimulate the immune system and kill certain cancer cells in a test tube, but it doesn't seem to work in people.

Are there safety concerns?

European mistletoe might be safe when used in appropriate amounts. Taking three berries or two leaves or less by mouth does not seem to cause serious side effects, but larger amounts can be unsafe and cause serious side effects. European mistletoe can cause vomiting, diarrhea, cramping, and other side effects.

Some people inject European mistletoe products. This can cause fever, chills, allergic reactions, and other side effects.

Because the correct amount is sometimes hard to determine, do not take European mistletoe without the advice of your healthcare professional.

Do not take European mistletoe if:
  • You are pregnant or breast-feeding.
  • You are an organ transplant recipient.
  • You have leukemia. European mistletoe might worsen this condition.
  • You have heart disease.
  • You are scheduled for surgery in the next two weeks.
