I have prepared and used Miracle-Mineral-Supplement enemas. (the nut that made the fetish remark has his own problems..:o) Anyway prepare it as usual..a cleansing enema first then the Miracle-Mineral-Supplement . I have never used more than a 5 drops..plus the citric acid and then add pure water.
I see nothing wrong with using it like this, and I suspect it may get into the system faster and degrade less than when taken orally. I don't think a strong solution would be a good idea, but thats just my opinion. Problem is there is just no way to measure the results with either the oral or rectal route. My personal experience with Miracle-Mineral-Supplement has been very good though and I recommend it to anyone.
When I first started taking it, I just could not stand the taste and I took a short length of clear IV tubing which is not much larger than spaghetti and attached it to a 50ml syringe. Swallowed the tube and poured the MMS solution in the open syringe..no bad taste and the IV tubing is so small that unless you have a really sensitive gag reflex you will not have any problem swallowing the tube.
I view any of the methods, drinking, swallowing the tube, or MMS enema as a lot less to deal with than some of the procedures and treatments the medical community come up with.
