Coconut oil is a miracle product, and Shailene Woodley recognizes its benefits in an interview with Into the Gloss.

"You can do something called 'oil pulling' where you swish coconut or sesame oil in your moth when you wake up and spit it out. It's amazing!" she told ITG. "It really makes your teeth whiter, because the plaque on your teeth is not water soluble, it's fat-soluble."

The April Marie Claire cover star also has some other rather obscure beauty rituals.

Woodley said clay is one of the best things to put into your body, a tip she picked up from an African taxi driver. She even told readers that they should learn more about customs from taxi drivers.

"So, I've discovered that clay is great for you because your body doesn't absorb it, and it apparently provides a negative charge, so it bonds to negative isotopes. And, this is crazy: it also helps clean heavy metals out of your body."

Her friend started eating it, but was worried when her bowel movements smelled like metal. Woodley researched and found that it was completely normal when you first start eating clay. And she warned that the most important thing was knowing the source of the clay. She personally likes Mountain Rose Herbs.

She also talked about how the sun helps her "genital issues."

"Another thing I like to do is give my vagina a little Vitamin D," she said. "I was reading an article written by an herbalist I studied about yeast infections and other genital issues. She said there's nothing better than vitamin D. If you're feeling depleted, go in the sun for an hour and see how much energy you get. Or, if you live in a place that has heavy winters, when the sun finally comes out, spread your legs and get some sunshine."

Woodley is very into living life naturally, so she's very particular about the beauty products she uses, such as being a fan of 100% Pure. And though she's passionate about her way of life, she knows there are times she has to be respectful of other people.

That's why you'll never catch her looking completely natural on TV or at an important red carpet event. But you might see her wearing running shoes beneath her beautiful gowns.
