Hi, I'm the one below with the nice "new" feet and I

thought I would list the colours that come out of the body and what they mean. I got the list from one of the "operators" of the machine in my area:

black - detoxifying from liver
black flecks - heavy metals, chemicals
brown - from liver, cellular debris, tobacco
dark green - from gallbladder
orange - from joints
red flecks - blood clots
white cheeselike particles - yeast
white foam - lymphatic system
yellow green - kidneys, bladder, urinary tract, female
parts/prostate
blue - triglycerides (fat)

I no longer get any black flecks (after weeks of masses of them) and see mostly plain brown now.
