Pillow Mist

Will there be any long-term damage done if I use the B&BW pillow mist every night?
I have not been able to sleep good all summer. So, last week I bought the Black Chamomile Pillow Mist from Bath and Body Works. I have been using it every night and it works really well.
But my mother is a nurse and she says that it probably isn’t good for me to use this every night because I don’t know what kind of chemicals and whatnot is in it. I looked on the bottle and it does not have the ingredients listed. I want to know if there are any harmful chemicals in the pillow mist and if this is a safe product for me to use every night?
Many customers use these products every night. Maybe if you want to be on the safe side swich it up. By the lotion, and shower gel and start taking baths, and only spraying it on desperate nights. Honestly, there hasnt been much research done to see if there can be any damage, but the aromatheropy line is based on natural ingredients, but as for scent and all that, it would be the same if you were spray any kind of linen spray on your sheets every night.
