Dark stuff coming out of skin during bath

[Guest guest]

This is going to sound wierd but I've noticed when Ido an herbal cleanse, I get

dark oily stuff under my nails when I sweat during a bath.

I happened when I did my lung cleanse, and now during my kidney cleanse. The

amount is incredible. When i drain the tub, there is a ring of it around the

tub.

If this is toxins coming out, that would explain the fatigue I get when doing

the cleanses.

Just wondering if anyone has noticed this when doing a bath or sauna (whether

cleansing or not).
