I remember a testimony from about 5 years ago from a guy who had worked with asbestos for years ... after he started taking sodium chlorite and drinking a grass drink, he started having small bumps (like goose bumps) appear all over his arms.
Then little particles emerged from the heads that developed on these bumps ... they were asbestos particles that had been "stored" away by the body.
Your body can produce some very strange skin reactions using this protocol. I would strongly suggest that you continue using wheatgrass/barley grass, etc... And try to drink a liter of water per day per 40lbs of body weight.
As far the Miracle-Mineral-Supplement goes, if the skin condition is tolerable to you, then just continue it. If it is bothersome, or worsens, then consider going down by a drop. If it is a healing reaction, and you discontinue, then you will give the pathogens time to regroup and colonize again.
