If you want to remove toxins like heavy metals ,as the article writes, you have to undergo a process called chelation. You infuse a compound which binds to the heavy metals and makes it water soluble which can be excreted via kidneys. The problem with this is that you lose a lot of other benificial nutrients in the body too and is only recommended for heavy metal poisoning.
And people don't understand the PPM ( parts per million) concept. Some of the toxins in you are like "a drop in the ocean". No real need to worry about it.
