A very potent edible biocide that purifies water, prevents parasites, and disinfects produce and any surface. GSE is 10-100 X more potent than chlorine, iodine, or silver oxide, yet it can be diluted and drunk to kill bacteria, fungi and viruses and to detach parasites, while sparing beneficial intestinal flora. Bacteria do not develop antibiotic resistance to it. In tablet form for those who don’t like the intensely bitter taste. Perfect for first-aid kits, travel, eating out, visiting relatives, life, and other adventures. 100 - 125 mg tablets
