Mistletoe has been hanging in archways around the Christmas season for centuries. When I was a child in my hometown in Oklahoma, we would look high up in trees to spot a bunch, try to knock it down, and drag it home like it was a trophy (The mistletoe is the official floral emblem for the state).
If you got lucky, some round, white-colored berries would be attached. Those are considered the fruits of the plant.
Mistletoe is a hemiparasitic plant that originated primarily from the British isle in Northern Europe. It grows as a hanging bush on branches of trees such as poplar, pear, cherry, birch, willow, and chestnut.
Mistletoe has long since been considered a pagan religious symbol and was believed to have magical properties ‒ used to cure diseases and as a talisman of good fortune and fertility. The Greeks fawned over mistletoe for its healing powers.
According to the Smithsonian, the romantic symbolization of the mistletoe comes from ancient Norse mythology.1 In the tale, Baldur, the grandson of a Norse god, woke up convinced that every plant and animal on earth wanted to kill him. His Mom, Frigg, the goddess of love, while fearing for his life, pleaded with all the plants and animals of the world to promise not to harm her son. She forgot, however, to secure her son’s life with one living being ‒ the mistletoe. He was stabbed by the god Loki with an arrow made from mistletoe, and Baldur’s fear became a reality. The Christmas tradition stuck in Northern Europe as a reminder of what Baldur’s mother forgot, or so they say. In America, it has been incorporated into holiday celebrations.
By the 18th century, it became ubiquitous with Christmas cheer. The Romans even legalized marriages by kissing under mistletoe. The custom of kissing under mistletoe continues as we all know today. Let’s be honest. It is a little creepy to think that anyone can be under the mistletoe, such as crazy Uncle Bob, and you are supposed to plant a kiss. I think not! Boundaries, friends. It is an adorable decoration, yes, but I also don’t want to share any germs with people I don’t know whether we are in COVID times or not. I am not even supposed to kiss my dog, and I know her!
Mistletoe is touted for many benefits other than kissing. The plant contains toxic amines; however, eating its berries can cause vomiting and stomach pain. So please don’t start chewing your decorations. However, studies show that mistletoe is not quite as hazardous that historically it was made out to be.2 Native Americans have been using mistletoe for hundreds of years as a therapeutic agent. It was brewed into a liquid, and people who suffered from headaches bathed their heads in the tincture. There are 1,300 mistletoe species worldwide, and in the United States and Canada, we have more than 30. Globally, there are some species considered endangered. Mistletoe is a parasite and likes to grow on apple trees, for example, but orchards have been disappearing. There are also climate issues and the stress the mistletoe can cause to a tree.
Health Benefits and Therapeutic Uses of Mistletoe
- Calming and healing properties of mistletoe result in it being used to treat cases of epilepsy, hysteria, anxiety attacks, nervous fits, and neurosis.3,4
- Mistletoe is often used as an herbal sleeping aid. The chemical makeup in the herb may promote the release of neurotransmitters such as dopamine to support restful sleep.5
- Research shows that it is a cholesterol lowering for low-density lipoprotein (LDL), and it increases high-density lipoprotein (HDL).6-8
- Many mistletoe extracts showed radical-scavenging activity and protective against oxidative stress.9-12
- The ability to kill fungal infections, such as aspergillus – a flesh-eating microbe – and candida.13
- Mistletoe shows bi-directional activity in the treatment of cancer. Helping with fatigue, anxiety, and pain and it shows antitumor activity by cytotoxicity, inducing apoptosis as well as the inhibition of angiogenesis.4,14-19
- In China, medicinal plants from ancient to modern history have been used in patients with angina pectoris, congestive heart failure (CHF), systolic hypertension, arrhythmia, and venous insufficiency for centuries.20
Holiday traditions can be because of religion, customs, and folklore. During this season of cheer, when you look up and see the lovely decoration while deciding if this is a kissing moment or not, remember there is a history and use for the mistletoe that we know and love.
