Your memory serves you well. I have the sota pulser which doubles as CS maker. It makes about two cups in two hours, so it would take a long time to make enough to fill a tub. Adding it to the bath water seems to be benifical, I use the CS that I cook too long,for that. It seems to have left or at least is dormant, everywhere except my face. I am still having issues with my sinus, nothing like before. I'm going to get a snorkel, I can't hold my breath long enough to drown it on my face.
I use Epsom Salts in my bath along with Sea Salt , lavender, tea tree, CS, and what ever else is handy. It is warmer here so I have been swimming in the ocean alot.
One more good thing to report I am not having near the pain issues with my joints and back these days.
I've been using kelp for iodine, got Lugols the other day, so I am giving that a try. Still OPing? I am. It has been really hard coming back from this hell, and costly. I've decided it takes alot of money to stay healthy as well, unless you grow your own food. I've been using CS in the vegtable garden, can't wait to see the results of that. My chickens have on it a while and the yolks of their eggs are the color of the sun at sunset. The eggs taste like the ones you would eat in Heaven. Here is another chicken story for you. I watched the meet your meat video(Ana's blog). The next morning, sitting outside I was thinking of it, just as my little yellow Batham came into view. I swear this is true. Up she hops on the arm of the chair that I was sitting in, she stays for the longest time, letting me pet her and making cool chicken noises. Now I know horses can read your mind, but chickens too. I don't think I will put Iodine in their water. What was the name of that book, where the animals, pigs took over the farm? The outside world beckons. Stay well.
