Mistletoe is a plant that grows on an assortment of trees including willow, apple and oak trees.
The tradition of hanging it in the house dates back to the times of the ancient Druids.
It is supposed to possess mystical powers which bring good luck to the household and wards off evil spirits.
It was also used as a sign of love and friendship in Norse mythology.
When the first Christians came to Western Europe, some tried to ban the use of Mistletoe as a decoration in Churches, but many ignored the ban and continued to use it!
York Minster Church in the UK used to hold a special Mistletoe Service in the winter, where mistletoe users in the city of York could come and be pardoned.
The custom of kissing under Mistletoe comes from England.
The earliest recorded date mentioning kissing under the mistletoe is in 1784 in a musical.
There was kissing under the mistletoe in the illustrations in the first book version of 'A Christmas Carol' published in 1843, and this might have helped the idea of kissing under the mistletoe.
The original custom was that a berry was picked from the sprig of Mistletoe before the person could be kissed and when all the berries had gone, there could be no more kissing.
The name mistletoe comes from two Anglo Saxon words 'Mistel' (which means dung) and 'tan' (which means) twig or stick! So you could translate Mistletoe as 'poo on a stick'.
