I can't figure out where you are getting this information. I have not read about sniffing the fumes for sinus and asthma. Dangerous. Corrosive. I have read, and tried, the use of activated and diluted Miracle-Mineral-Supplement for sinus rinse. No problem at all. I assume the same would be true for enema. Activate then dilute with water; just as if you are taking you normal daily dose.
