From BBC news:
"The key ingredient of the water, called Microcyn, are oxychlorine ions - electrically charged molecules which pierce the cell walls of free-living microbes.
The water can only kill cells it can completely surround so human cells are spared because they are tightly bound together in a matrix. It is made by taking purified water and passing it through a semi-permeable sodium chloride membrane, which produces the oxychlorine ions."
One study reports decreasing wound healing time from 55 days to 43 days of foot ulcers, compared to the control group (both groups received standard antibiotic treatment, the control group did not receive the water treatment.)
The current targeted use is for increasing healing times for diabetec foot ulcers. Their current study: Oculus Initiates Patient Enrollment in Phase II Study of Microcyn(R) Technology for Treatment of Mild Diabetic Foot Infections.
