Mistletoe is an aerial parasite that has no roots of its own and lives off the tree that it attaches itself to. Without that tree it would die. Mistletoe was thought to be sacred by ancient Europeans. Druid priests employed it in their sacrifices to the gods while Celtic people felt it possessed miraculous healing powers. In fact, in the Celtic language mistletoe means "all-heal." It not only cured diseases, but could also render poisons harmless, make humans and animals prolific, keep one safe from witchcraft, protect the house from ghosts and even make them speak. With all of this, it was thought to bring good luck to anyone privileged to have it.

Norsemen offer us a beautiful symbolic myth about mistletoe. The story goes that Mistletoe was the sacred plant of Frigga, goddess of love and the mother of Balder, the god of the summer sun. Balder had a dream of death, which greatly alarmed his mother, for should he die, all life on earth would end. In an attempt to keep this from happening, Frigga went at once to air, fire, water, earth, and every animal and plant seeking a promise that no harm would come to her son. Balder now could not be hurt by anything on earth or under the earth. But Balder had one enemy, Loki, god of evil and he knew of one plant that Frigga had overlooked in her quest to keep her son safe. It grew neither on the earth nor under the earth, but on apple and oak trees. It was lowly mistletoe. So Loki made an arrow tip of the mistletoe, gave to the blind god of winter, Hoder, who shot it, striking Balder dead. The sky paled and all things in earth and heaven wept for the sun god. For three days each element tried to bring Balder back to life. Frigga, the goddess and his mother finally restored him. It is said the tears she shed for her son turned into the pearly white berries on the mistletoe plant and in her joy Frigga kissed everyone who passed beneath the tree on which it grew. The story ends with a decree that who should ever stand under the humble mistletoe, no harm should befall them, only a kiss, a token of love.

What could be more natural than to translate the spirit of this old myth into a Christian way of thinking and accept the mistletoe as the emblem of that Love which conquers Death? Its medicinal properties, whether real or imaginary, make it a just emblematic of that Tree of Life, the leaves of which are for the healing of the nations thus paralleling it to the Virgin Birth of Christ.

Later, the eighteenth-century English credited mistletoe not with miraculous healing powers, but with a certain magical appeal called a kissing ball. At Christmas time a young lady standing under a ball of mistletoe, brightly trimmed with evergreens, ribbons, and ornaments, cannot refuse to be kissed. Such a kiss could mean deep romance or lasting friendship and goodwill. If the girl remained unkissed, she cannot expect not to marry the following year. Whether we believe it or not, it always makes for fun and frolic at Christmas celebrations.
