## Questions & Answers

**Q: What’s the difference between 10 PPM and 20 PPM silver solutions?**
A: 10ppm (parts per million) means that for every million parts of the liquid, 10 parts are silver. 20ppm means that for every million parts of the liquid, 20 parts are silver.

**Q: How do I choose between a spray or dropper application?**
A: Sprays are convenient for broader areas or quick applications, while droppers offer more precise control.

**Q: What’s the advantage of True Colloidal Silver over ionic silver?**
A: True Colloidal Silver contains particles, not ions, offering more stability and deeper, longer-lasting antimicrobial effects.

**Q: Are refill bottles more economical than sprays or droppers?**

### ⭐⭐⭐⭐⭐ It works!

I always have this in the cupboard. Using it sensibly, it acts for me as an antibiotic and an effective antiseptic for wounds etc.

### ⭐⭐⭐⭐⭐ This silver treatment is truly outstanding.It comes in a glass bottle,as silver in plastic is not a good thing apparently!!
*by M***Y on 22 September 2014*

Our health is so important,when you look at modern living in general...As I am not young any more and a diabetic it is vital I keep on top of health issues as they arise. I bought this Enhanced Colloidal silver a while back,and at the same time I also bought another version in a plastic bottle.I used the plastic bottle first,for various ailments., eg.mouthwash,toothache from exposed nerve etc and I was not impressed,the results were always poor!!.I even used it on a dog's sore paw with no visible result. Then I had an itch on my inside right thigh.It has driven me mad for weeks,I thought perhaps it was the heat..I tried all the expensive creams from chemists,including cortizone,but back it came each time with a real vengeance -- I also tried the silver from the plastic bottle,again to no avail... In desperation yesterday I saw the box unopened of this colloidal silver here advertised in a glass bottle,so I thought,oh well what have I got to lose.I used cotton wool pads,soaked them with this silver,applied,and in one hour the itching had stopped...I could also see the redness disappearing that had become "angry looking" as I was scratching it so much.I went through the whole night without a murmur of an itch,nothing.Today the patch is healed....I know diabetics are famous for skin not healing as quickly as non diabetics,but this healing was incredible,All that interminable itching,much worse at night, and the cure lay all along in the bottle on the shelf!!...I am totally won over,and I have nothing to gain by telling this apart from hoping to help another person who perhaps is desperately looking for a cure. I am now going to buy another bottle of this of this for use as an Autumn/Winter gargle,as I never have flu injections through a bad reaction I once received where I passed out.. .So now my silver can be my main stay to get me through the Winter months.
