NUTRIBIOTIC - Travellers Friend, Grapefruit Citrus Seed Extract
GSE is ideal as a safe and simple way to treat drinking water when camping, back packing or in any emergency situation where safe drinking water is not obtainable, and boiling(or distilling) is not practical.
Available water should first be filtered. (At the very least, let suspended particles settle.) Retain the clear water and add 10 to 25 drops of grapefruit seed extract(less for questionable tap water, more for stream or pond water) for each one gallon of water. Shake or stir vigorously and let sit for a few minutes. A slightly bitter taste may be noticed. This is just the inherent taste of the GSE.
Safe and easy to carry!
