It looks as though Jennifer Aniston is trying really hard these days to live in a very healthy and clean environment, no matter what the cost is. The Hollywood actress has reportedly "banned chemicals" while shooting her latest box office offering, Cake.

Jennifer Aniston, Justin Theroux Put Their Wedding On Hold Again?

According to US Weekly's print edition on Friday, Aniston even forbid her co-workers to use offending items such as Listerine mouth spray, soda and cigarettes while in her presence.

"She'd say everything she uses is all-natural and she knows every product's ingredients," an insider says, reports Celebitchy. She even brought in licorice root - believed to be an herbal remedy for smoking.

Jennifer Aniston Feeling Pressure From Her Family To Get Pregnant? 

While her rep denies the story and says, "Jennifer is not the type to push anything on anyone," the insider says Aniston also proposed yoga and meditation with those around her, too.

Just last month, Aniston opened up about her beauty regime to Yahoo, saying that Theroux would take to extreme measures to make sure she would never "mess with her face."

"There is this pressure in Hollywood to be ageless," Aniston told the site. "I think what I have been witness to, is seeing women trying to stay ageless with what they are doing to themselves. I am grateful to learn from their mistakes, because I am not injecting s--- into my face."

She added, "No honestly, I see them and my heart breaks. I think 'Oh god if you only knew how much older you look.' They are trying to stop the clock and all you can see is an insecure person who won't let themselves age. I also have a fiancé who will put a gun to my head if I touch my face in any way."

The actress also credited her father and his Greek roots for her ageless face.

She said, "My dad [soap opera veteran John Aniston] is 100 percent Greek; he turned 81 and he barely has a wrinkle. And neither did my grandmother, who was 95 when she died. But it's also just water, drinking a lot of water, using really nice good products for your face. Don't overproduce, that's the other thing. Getting proper sleep is always important."
