Hanging mistletoe was part of the Saturnalia festival. In the Christian era, mistletoe in the Western world became associated with Christmas as a decoration under which lovers are expected to kiss, as well as with protection from witches and demons. Mistletoe continued to be associated with fertility and vitality through the Middle Ages, and by the 18th century it had also become incorporated into Christmas celebrations around the world. The custom of kissing under the mistletoe is referred to as popular among servants in late 18th century England. The serving class of Victorian England is credited with perpetuating the tradition. The tradition dictated that a man was allowed to kiss any woman standing underneath mistletoe, and that bad luck would befall any woman who refused the kiss. One variation on the tradition stated that with each kiss a berry was to be plucked from the mistletoe, and the kissing must stop after all the berries had been removed. People have reportedly been poisoned and died from consuming mistletoe. From at least the mid-19th century, Caribbean herbalists of African descent have referred to mistletoe as "god-bush". In Nepal, diverse mistletoes are used for a variety of medical purposes, particularly for treating broken bones. Mistletoe is the state floral emblem of Oklahoma and the county flower of Herefordshire. Every year, the UK town of Tenbury Wells holds a mistletoe festival and crowns a 'Mistletoe Queen'. One of the earliest references to mistletoe traditions in popular music is the 1952 hit 'I Saw Mommy Kissing Santa Claus', which was originally sung by Jimmy Boyd and has been covered by many singers. The song was written by British songwriter Tommie Connor and recorded in the US. The 1958 US hit 'Rockin' Around The Christmas Tree' refers to couples wanting to stop beneath the mistletoe. In 1988, the British singer Cliff Richard released a popular Christmas song called 'Mistletoe and Wine'. More recent Christmas songs referring to mistletoe traditions include 'Merry Christmas Everyone' by Shakin' Stevens (1991), 'All I Want For Christmas Is You' written and performed by Mariah Carey (1994) and 'Mistletoe' by Justin Bieber (2011).
