The way that I understand it is that if we supply the body with the raw materials and vital energy that it needs, the body becomes a very efficient self-healing and self-cleansing organism. Looking at it from this perspective, no, we don't need flushes that other people do if we are willing to wait for the body to do its thing. But, todays society has the attitude of "I want it yesterday!" So the differant flushs are used to speed up the process.
It really depends on how patient you are and how long your willing to wait for your body to correct itself.
I hope this makes sense and helps a little.
