I thought at first that the writer was joking, since human bodies automatically detoxify themselves constantly over the span of about 30 hours, and they need no magical treatments or "processes" to do it. It is hyper rare for anyone to need to be detoxified: maybe 1 on 100,000 people, once in a life time, and after being exposed in very unusual and rare circumstances to a toxin that their bodies cannot handle. "Toxic cleansing" happens every time one drinks a glass of water and every time one uses a toilet; the only toxins that a person has to worry about are a few metals such as mercury and lead, and no amount of "cleansing" will remove those toxins.
In other words, the writer of this pamphlet has no knowledge at all about the subject. Skip this one.
