Holiday Traditions: Mistletoe —> Mistletoe was considered a magical plant in Europe, especially among the Druids and Vikings, and holds significance in Native American cultures. Mistletoe is no modern quirk of Christmas, even Romans partook in fertility rituals beneath the mistletoe. Mistletoe stood as a neutral ground for feuding Norse tribes, who laid down their weapons in order to negotiate beneath the peace plant. The Druids thought it could protect them from thunder and lightning, as well. Whether you’ve got the urge to make out, hide from a storm or talk it out, beware as mistletoe is super poisonous.
