I made up 2 pints of dark gold CS that tested around 35 PPM and used them for sinus flushes with my Grossan water pick. Dark black stuff came out after a flush. I tried regular 10 PPM CS and did not notice the black stuff. Paul may have found that the burnt CS does something for sinus problems.
A friend has cysts on his testicles. I told him that DMSO works for internal cysts and a CS/DMSO spray could maybe reach the cysts. Any ideas? Brickey
