Vaginal rejuvenation is nothing new, but it’s most often done under the care of a physician. There are some natural ingredients that are highly praised for their ability to alleviate health problems. But there’s at least one method that’s rubbing some people the wrong way. So it comes as no surprise that Canadian gynecologist Jen Gunter is expressing her concerns with this alternative.

Apparently there’s a do-it-yourself method, that uses oak galls, which are tree deformities caused by wasp nests. They’re made when wasps lay eggs in the leaf buds of a tree, which allow the larva to develop inside.

Dr. Gunter has taken to her blog to blast this method by listing a group of symptoms that make it sound less than appealing. She warns that it can lead to painful sex, a lack of healthy bacteria and an increased risk of contracting HIV.

“Drying the vaginal mucosa increases the risk of abrasions during sex and destroys the protective mucous layer,” said Gunter. “It could also wreak havoc with the good bacteria. In addition to causing pain during sex it can increase the risk of HIV transmission. This is a dangerous practice with real potential to harm.”

We’re not sure how important it is to make your downstairs look new again, but this doesn’t sound like the way to go. Not by any means.
