Mistletoe dates back to the ancient Druids who considered the plant to be a sign of peace and goodwill. Warring parties would temporarily cease battle upon seeing mistletoe.
In spite of its toxicity, Germans called this plant, Gut Hyl or all-heal. It was used in various potions as a remedy and fertility drug. It was thought to give strength to the athlete, hunter, and swordsman.
Mistletoe is best known for romance. In some European cultures, a kiss under mistletoe is a proposal of marriage. However in the United States, it is simply a sign of love and friendship—not a serious commitment.
Both men and women are encouraged to stand under the mistletoe when hoping to receive a kiss.
