Mistletoe has been considered a plant that increases life and fertility, and protects from evil spirits (Celtic mythology). In Norse mythology an arrow made of mistletoe killed Balder, a brother of Thor. In some versions of this myth, Balder's mother Frigga brought him back to life shedding her tears that changed the red mistletoe berries to white. Frigga was so overjoyed that she blessed the mistletoe and promised a kiss to all who passed beneath it. Do you know other myths and traditions that goes along with Christmas?
