what is mistletoe used for christmas

Mistletoe has been a popular part of Christmas traditions for centuries. It's a parasitic plant that attaches itself to tree branches and grows in clusters. People would hang it in doorways or on walls as a symbol of good luck and protection. During the Middle Ages, it was thought that kissing under mistletoe would bring good fortune, so people started kissing under it as a custom during the holiday season. Nowadays, it's still considered romantic and people often hang it up in their homes during the holidays as a reminder of the season's joy and love.
