With over 900 types, Mistletoe (Viscum album), commonly known as European mistletoe, is a semi-parasite plant that grows on different host trees  and has been mostly known for being part of the Christmas tradition as well as being used for decoration in most of our countries, becoming part of those traditional Christmas symbols that became part of this special celebration. Other plants as Rafflesia arnoldii, the biggest flower in the world, are also example of semi-parasitic plants.
Kissing under the mistletoe tradition dates back to Roman times, being a later synthesis of the Sexual license of Saturnalia with the Druidic sacrificial cult [18,19].
The first documented used of Mistletoe (Viscum album) for the treatment of cancer dates back to 1920, when mistletoe extracts were introduced for the first time as a cancer treatment by Rudolf Steiner (1861-1925), founder of anthroposophy [9,10], a philosophy that postulates the existence of an objective, intellectually comprehensible spiritual world accessible to direct experience through inner development . But in Europe the use of Mistletoe is not limited to the treatment of cancer but also arthrosis, hypertension, arteriosclerosis, diabetes etc .
