Ultra SilverColloidal Silver | 500 PPM | 4 Ounce | Fine Mist Spray

First off the product is amber tinted a sign of quality and it shows up on my dogs coat I'm treating. The packaging is above and beyond. The spray bottle is shrink wrapped then put in a zip lock bag. No leaking. Hoping it helps a wound on dog can update that aspect later. I will buy again I believe the quality is good.

Nothing

I found this info online but have not tried it myself. I do use the 500 ppm silver sparingly and it works when we need a stronger solution to a problem.'The best way to get an estimate of the PPM of silver in your results is with an EC (Electrical Conductivity) meter. These are readily available from Amazon. Measure the EC of your results, and multiply that by 1.1 — it’s as simple as that.If you already have a TDS meter, you can use that; the resolution is not as good, but if you multiply your TDS reading by 2.5, you will get a reasonable approximation of the colloidal silver PPM.'

This has healed sores, KEPT ME FROM CATCHING THIS WINTERS BUGS, and much more

It will take some time to see results.

This is one of the better brands where you can actually see that it has the right color and taste. Right now there are a lot of brands selling this clear stuff that has little to no taste and when you put some in a cleat container and shine a laser thru it the result is almost the same as tap water. With this stuff the laser beam becomes Very visible indicating a good silver content. I've also noticed healing much much faster from cold symptoms, cold sores, and minor cuts and scratches etc. This stuff is well worth it and can be diluted with distilled water to a weaker concentration for daily maintenance. I usually take 1 tsp diluted down to 50ppm every morning to prevent catching colds etc with excellent results during the cold and flu season.

Didn’t know it was brown in color. Do not like this.

It did show that it was yellow but I need to spray it onto a cotton pad before applying. I have another one that is a supplement and it is clear.
