Potatoes are fantastic for many things, like making French fries or vodka.

But they are not a great choice for contraception.

A 22-year-old Colombian woman recently inserted a potato into her vagina and left it there for two weeks.

The potato sprouted roots, and then the roots began to grow. Inside her vagina.

According to Metro U.K., the woman complained to doctors about abdominal pains. When it came to light that she had been storing a starchy vegetable in her hoo-hoo, she told doctors she had done so on advice from her mother.

“My mum told me that if I didn’t want to get pregnant, I should put a potato up there,” she told medics. “I believed her.”

She may have wanted to Google that one for more information before taking action.

Doctors were able to remove the potato and roots without surgery, and the woman will not suffer any lasting physical effects.
