On cleansing medication, purging and my faeces just like that of corn and i never ate corn at this moment in time. what could be those corn like, pls?

No idea either, but: Healthtap physicians have repeatedly addressed this subject with a clear "no" answer to your question. There is virtually no value to colon flushes, cleansers, enemas, irrigation machines when the technique is accomplished to "detox" or eliminate "accumulated waste" or for weight loss. There are few real health benefits, but sigificant unjustified risk. Don't use colonics please unless prescribed.
