History of Mistletoe: Why is it the Kissing plant?


We’ve mentioned previously that mistletoe was prominent in the traditions of the Druids and the lore of northern Europe. The Druids used the mistletoe of their sacred oak as part of their ritual five days after the new moon following the Winter Solstice. In the Middle Ages it was hung from ceilings or placed above stable and house doors to drive off evil spirits and to insure fertility.


The word can be traced back to 2nd century Anglo-Saxon “mistel” for the word dung and “tan” for twig, mistletan being the Old English version of the word. This suggests the belief that mistletoe grew from birds, though we know now that it is the birds’ droppings in trees or the seeds’ sticky nature that adheres to tree bark.

Some would trace the tradition of kissing under mistletoe back to the Roman Saturnalia, indeed the Greek goddess Artemis (Roman: Diana) patron of the city of Ephesus (New Testament – Acts 19:24-41) wore a crown of mistletoe as an emblem of fertility and immortality. However, the most fully developed myth regarding mistletoe comes from the Norse mythology of the Vikings.

The story goes as follows. Baldar, the Norse god of the summer sun, saw in a dream his own death. Frigga, his mother and the goddess of beauty and love — and from whom we get the word Friday — compelled the elements, plants and animals not to kill Baldar. But she neglected to extract this same promise from the young and insignificant mistletoe. The mischief god Loki (brother of Thor) realizing that mistletoe grows on trees and has no roots in the ground fashioned a poisoned dart from mistletoe and with the aid of Baldar’s blind brother Hoder shot the mistletoe missile to kill Baldar. His death brought winter and his mother’s lamentation. So says the medieval Norse myths we learn from the Eddas.

Later traditions say that Frigga’s tears over her son changed the red mistletoe berries white, and henceforth and forever mistletoe would bring love rather than death into the world. Any two people passing under mistletoe would exchange a kiss in memory of Baldar.

Later Christian customs called it Herbe de la Croix or Lignum Sanctae Crusis for “Wood of the Sacred Cross” because of the belief that it was used to supply the wood for Christ’s cross. For its role, mistletoe was condemned to be a parasitic vine. Further penance for the plant was that it bless everyone who walked beneath it.

  • Nicely done…
    Happy Christmas!
    Or whichever holiday you celebrate… Or don’t.

    • Thanks Greg. That seems to cover everything.

  • Norse myth is very clear that Baldur stayed dead. The failure to resurrect him is as important their story cycle as the crucifixion is to Christians. The story you relate is most likely a bowdlerization for children but it is not Norse myth.

    • Bob,

      Thanks, you are correct. Balder might have been returned from death, but for further treachery. A promise was extracted from Hel, goddess of the dead, that Baldur could return to the realm of the living if all things shed tears for the dead Baldur. An attempt was made as messengers were sent everywhere requesting that all things mourn. But Tokk the giantess refused to cry for Baldur. Some believe that Tokk was Loki in disguise. Not until after Ragnarok, the twilight of the gods, would Baldur be reborn…according to the 11th century Prose Edda and the 12th century Poetic Edda. I’ve corrected the article.

  • When was mistletoe 1st used at Christmas?

    • Chris,

      Good question, hard to answer. Let me tell you what we know and what we don’t know. We know its mystical properties were described before the time of the Druids, we first read about mistletoe over 2300 years ago from the Greek philosopher Theophrastus. But it was Pliny the Elder who lived between 23 to 79 BC who wrote detailed descriptions of the attitude of some contemporary people toward the mistletoe. He noted that while mistletoe lived in deciduous trees like the oak, after the oak leaves dropped in Fall, the mistletoe was still vital, speculating that the life of the oak was in the mistletoe and that it had mystical powers as long as after it was harvested it did not touch the ground. Could this be why it is tied aloft? The Roman writer Virgil talks about his hero Aeneas carrying a “Golden Bough” into hell. By using the flickering light of the mistletoe plant he was able to pass through the forest and transported across the river Styx. So you see that mistletoe’s significance is ancient indeed and pre-Christian.

      How it became integrated into Christianity is uncertain. Perhaps the earlier beliefs of mistletoe’s influence on fertility and conception were involved. What we do know is that the first documented case of “kissing under the mistletoe” goes back to the 16th century England were it was a popular custom.
