Parts Used & Where Grown

Mistletoe grows as a partial parasite on a variety of trees—particularly pine, apple, plum, poplar, and spruce—across northern Europe and Asia. The young leafy twigs with flowers are used. Mistletoe’s white berries are potentially toxic and should be avoided. American mistletoe, various species of Phoradendron, are similar but have not been widely studied. They should not be substituted for European mistletoe until more information is available.

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement,little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

The ancient Druids of northern Europe and other pagan groups revered mistletoe, particularly when it infected oak trees (a rare occurrence). Over time, this reverence of mistletoe was translated into the Christian ritual of hanging mistletoe over doorways at Christmas. The custom of kissing under the mistletoe may be a remnant of pagan orgies held before mistletoe altars.1

The name mistletoe is said to derive from the Celtic word for “all-heal.” This correlates with its historical use for everything from nervous complaints to bleeding to tumors.2 It is difficult to categorize all of the uses of mistletoe, particularly when one looks at the vast number of uses for this herb in traditional Chinese and Korean medicine. In the early 20th century, Rudolf Steiner created what is known as anthroposophical medicine. This mystical system used a variety of unusual remedies, including special extracts of mistletoe for injection. Steiner helped bring mistletoe into the modern era of scientific research, particularly as a potential treatment for cancer.3
