Mistletoe has always been seen as the true magical feminine partner to holly's masculine. Occasionally however mistletoe has been referred to as masculine due to the fact that the white berries are symbolic of semen, whilst the red berries of holly represent menstrual blood.
Regardless of which gender, if any, you prefer it does not detract from the fact that the Druids considered mistletoe to be a gift from the Gods and as such it was highly revered and handed out to the community during religious ceremonies where it was referred to as 'all heal'.
Today its healing properties are recognised by homeopaths as it is used in the treatment of certain cancers. It is also a protective plant and if worn around the neck, is said to confer invisibility!
