Here's why:
* It answers the question "what kind?" When you say "natural beauty," "natural ingredients," or "natural talent," you're specifying the *kind* of beauty, ingredients, or talent.
* It doesn't act like a verb or a noun. You wouldn't say "I natural the door" or "The natural was beautiful."
Here are some examples of "natural" used as an adjective:
* The natural world is full of wonder.
* She has a natural talent for music.
* We use only natural ingredients in our products.
