According to a CBC News report, ancient druids believed mistletoe had magical properties because of the way it grows, never touching the ground and without taking nourishment from the earth. However, University Hospital of Wales in Cardiff researchers are warning there is nothing magical about the use of mistletoe extract for the treatment of cancer, and in fact, it can cause harm.

Serious side effects from the injection of mistletoe extract have been reported in the Christmas issue of the British Medical Journal, including a case concerning a 61-year-old woman who had a tumor-like growth develop under her skin, brought on when she self-injected herself with mistletoe extract. The researchers warn that the use of mistletoe extract has been shown to cause a severe allergic reaction, breathing difficulties, joint pain and kidney failure. Some studies have shown that mistletoe might actually lead to cancer growth.

Edzard Ernst, a professor of complementary medicine at the Universities of Exeter and Plymouth is quoted as saying, "The idea that mistletoe may help treat cancer is based on that the idea that mistletoe, like cancer, is a parasitic growth that eventually kills its host." The researchers of this published study indicated that there are over 30 mistletoe extract preparations available in Europe, and its use by cancer patients is well-known.

From another source, the National Cancer Institute's overview of mistletoe includes the following:

• Mistletoe is a plant that grows on several types of trees and has been used since ancient times to treat many ailments.
• Mistletoe extract has been shown to kill cancer cells in the laboratory and to boost the immune system.
• Animal studies have suggested that mistletoe may be useful in decreasing the side effects of standard anticancer therapy.
• Many human studies using mistletoe to treat cancer have been done in Europe with unclear results, and a few clinical trials in the United States and abroad are in progress.
• Very few bad side effects have been reported from the use of mistletoe extract, though mistletoe plants and berries are poisonous to humans.
• The U.S. Food and Drug Administration (FDA) has not approved mistletoe as a treatment for cancer or any other medical condition.

MTV -- the ultimate source of music videos and pop culture -- has been around for 25 years now. And that amount of time makes for a lot of memories.

So in recognition of the entertainment MTV has offered over the years, Indystar.com, Indiana's #1 local media site, takes a walk down memory lane and counts down 25 best MTV memories. It's fitting that many of the memories include actual music -- although some may say MTV is not really about music anymore, with music videos hard to come by -- so Michael Jackson's 1983 14-minute video Thriller makes the list and so does the 1985 performances of Live Aid, a conglomeration of musicians who sang to raise money for famine relief in Ethiopia.

But many memories are not recollections of music videos -- or even musical performances. They are nostalgic remembrances of other media events -- like a kiss between Madonna and Britney Spears during an award show, the running of the popular Beavis and Butthead show and Remote Control game show, peeks into spring break extravaganzas, and roof-raising reality shows like The Real World and The Osbourne's.

And even one socially-conscious piece that aired to raise awareness of testicular cancer. On May 23, 2000, wacky, stunt-pulling comedian Tom Green let viewers into his private world, in an operating room while he underwent surgery to remove a cancerous testicle and several lymph nodes. Green survived the surgery well -- and he is surviving cancer still today -- and his public handling of a serious disease goes down in MTV history as something truly memorable.
