I have to disagree. If you are talking about the pearl drop stuff. I believe man made chemicals have no place in our bodies in my opinion. Just cause you won't drop with a heart attack or get a rash doesn't mean its not stressing and adding toxins to the body.

I understand that the body has to deal with everything you eat, drink, breath, absorb etc and I don't believe toxins do you any good.

Think about a little chemicals in your toothpast-no, won't do much. plus shampoo and conditioner and soap, and hair gel/spray, and polution and in water and in made main so called foods (almost all) and in fruit and veg and meat and dairy and work enviroment and prescription drugs we conned into and all the other things we love to take to get rid of that head ache that is there because...? the crap booze etc etc etc

Personally I think that natural stuff tastes better and smells better and feels better (once you get use to you notice a big differance-you can smell the chemical fakeness of it all)

Probably hard to find a study saying brushing teeth a couple times a day will do anything (not that any of the big companies would put out the money to do that).

But it makes sense to me that it all adds up.

Honestly though you feel cleaner once you get use to not covering your self with chemicals. Skin is a big spunge...

Absorb alot in mouth too.

Alluminum-there is lots of studies on that.
