Review: The WHY, HOW and WHEN. One of the best Colloidal silver products on the market, why and tips on review. Try it = Love it - !Note: The manufacturer supplied a review or discounted sample for my own evaluation. I only accept / request items that I'm interested in and the opinion of the product is my own personal view. ***PERSONAL OVERALL OPINION*** This seems to be one of those products that when you come across the products page on desertcart, you think ??? What on earth is this? But then, when you start gathering information, on everything that it can actually do, and one feels like WOW, really!?! At least, been honest, these were my thoughts about this product. Now that I have tried it for over a month… Would I buy it again? YES, but instead of the offered small bottle, I would simply buy the big one. Although, I'm grateful for the opportunity given, as a little product goes a long way and I have been able to discover an amazing and unknown product to me. In order to complete my review, in case it helps, I am sharing all the info I have on the product, so you know exactly what this product is, what it's used for and how. The best way to describe this product is as a natural antiseptic, which by what I have read, it has been used for over 6000 years (so it must be effective) It's important to remember and I must point out, without getting into too much detail, that without any negative reports or any health related issues (that I am aware of, after a lot of reading) that the ingestion of colloidal silver was banned in the European Union at the beginnings of 2010. This is in fact what many refer to as a "Worldwide Battle". As a very brief overview, we could simply say, that the government tries to make it very difficult to sell silver products as Colloidal Silver, as a food supplement because it directly competes with the antibiotic market (makes a lot of sense to me) In the United States, Australia, New Zealand and many other countries Colloidal Silver is still greatly used as a food supplement. ***How can we use colloidal silver?*** We can: *Ingest orally I have taken it orally and I'm standing on my two feet better than ever ;) *Breathe it's vapours / inhale it With a nebuliser, a facial steamer (much cheaper) or by the old pan and towel method. *External applications Apply it on cuts, burns, grazes.. On humans as well as on our pets ;) ***What can it be helpful for?*** Orally *Fatigue *Gastro-intestinal problems *Low immune system *Infections (in general) Inhaling it's vapours *Respiratory infection *Colds *Pneumonia *Bronchitis *Sinusitis External applications *Burns *Skin irritations *Bacterial skin infections *Cuts *Grazes ***Anything important to know?*** That if you're taking it orally, you can't use a metal spoon, as it reduces the effectiveness. The kiddies syrup plastic spoons or "calpol" syringes are the easiest to use. Always leave the product under the tongue, for one minute before swallowing (for better absorption) Taste is not too bad ;) ***How much do I take?*** ***How do I apply it?*** Orally As a nutritional supplement: ½ a teaspoon /2.5 ml per day To boost immune system: 2 teaspoons /10ml per day. 5ml each time on an empty stomach For temporally illnesses as a bad cold etc.: 1 teaspoon / 5ml up to 3 times a day (morning, at noon and at night). Total of 15ml per day. For long term treatments (several months): 2 teaspoons per day/ 10ml per day. With a nebuliser / inhalation Put 2 teaspoons into the nebuliser container, turn it on and breathe slowly and deeply for around 15 minutes (or until the liquid has disappeared) whichever happens first. Repeat three times a day for colds, pneumonia, bronchitis and sinusitis. External applications - On skin You can wet a bandage or a dressing in colloidal silver and apply it on the area. You can also spray it directly on the area to treat. ***What about my Pets?*** As with humans it is possible to use colloidal silver either externally or internally. External use: Sprayed to the required area, at least 3 times per day, for at least one week. Internal use: Administered with a feeding syringe or adding it into your pet’s water or food. +++PROS+++ + 1 Product with many uses + Easy application + Taste is not bad + Does not seem to sting on skin applications. I have one daughter that has complained on a little graze, but she was moaning before I even touched the area, so?!? Not sure on that. ;/ My son, said it didn’t sting on a paper cut (he is younger than my girl) + Effective After having a few internal infections from a non-completed surgery earlier this year, I have been on 3 courses of two different antibiotics at once. As soon as I seem to recover and the treatment is finished, infection comes back shortly after. It has been bringing me down greatly. Finally I have used Colloidal Silver for the past month… And so far (fingers and toes crossed) Infection has not come back this time. I even feel better than before as it seems to help with overall fatigue. I will make sure, we never run out of this product. + Value for money For its numerous uses Because a little goes a long way. ***PERSONAL TIP*** If comparing prices and brands, as we all do. Always check the ppm/ml contents of the product. There is another ones been sold at the same price, and only contain 10ppm/100ml Which is 4 times less silver than in this Colloidal Silver from Institut Katharos. Therefore this Colloidal Silver is one of the best and most concentrated ones in the market. The water used to dilute the product is also ultra-purified and the pureness of the silver is 96% ionic silver (one of its purest forms) ---CONS--- None ***WHAT WOULD I IMPROVE / CHANGE?*** On the box it says, expiry date, from 6 months of opening. But my bottle already came open with the spray nozzle on, so…???!!! That has confused me a little. Besides that small comment, I am very happy I have discovered this superb and effective product and will always have a bottle at home. From a review request to a loyal customer.
Review: Fantastic product - Top marks all round because of great price value for money swift delivery and as you get two bottles The main container for the colloidal silver and a small spray bottle to dispense the liquid prior to any use or application Totally amazing

## Questions & Answers

**Q: Is it in a glass bottle**
A: Yeah, both are glass.

**Q: Not sure his small the silver particle has to be to determined it as nano...are they Nana? Size I'd a human cell?**
A: The ionic silver has nanoparticles 0.15 nanometres and the Colloidal 1-5 nanometres. The smaller particles are more bioavailable and my understanding is they do pass over the human/animal cell barrier.

**Q: Has anyone got the correct link to the ebook the one I got in the little leaflet with this isn’t working**
