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: A good product, the small spray bottle is a very useful addition. has a mild metallic taste - This is the 2nd time ive purchased this product and i haven't turned blue yet drinking it... regardless id rather drink (intermittently) a lab-tested product then risk the home made stuff to avoid the potential side effects I've heard about, so this fits the bill nicely. It's got a slightly more metallic test then some other brands ive used before, but its very mild. i appreciate the glass bottle. the spray bottle is very handy. ive used it on rashes, cuts and burns, as supposedly it helps heal faster, but ive never measured that. other ways ive usually used it, is to hold a drop/ spray under the tongue, and spray into my ear and nose when ive had a cold and am congested, i feel it also helps reduce the time I'm ill. my understanding is the silver ions, are spikey and puncture the bad stuff- but im not a scientist, i just like the idea of simple natural products. (other natural stuff I enjoy includes oregano oil, oysters for bioavailable zinc, apple cider vinegar, tamarind using glass food storage, and grounding feet in damp earth alongside natural sunlight. It's the simple hippie things but they seem to add up to my overall sense of well-being so ill keep using them)

## Questions & Answers

**Q: can I use this to clean my jade face roller?**
A: I don't see why not, but I wash mine with some antibacterial handwash. Save your money!

**Q: Is this definiatelly colloidal silver or ionic?**
A: This is definitely genuine colloidal silver I have recently had viral pneumonia and was hospitalised but I was quickly discharged and sent home feeling so ill I also had an infection in my throat. There is nothing on the NHS to treat viral pneumonia but I could have had antibiotics for my throat infection. I used colloidal silver and had excellent results. I have also used it to spray in to my eyes as I have had long term Blepharitis which is very painful.I have tried all the eye drops the Hospital have given me and also bought every kind on eye drops on the market and Colloidal silver is the only product on the market that works for me.I use it for so much more and will never be without this fantastic product.Well worth the money

**Q: Can this be used or does it help clear up wart/skin tags on neck area**
A: No, I don't think it will have any effect. For skin tags, the fastest way is to tie them off with cotton. Make sure to keep the cotton tight to cut off the blood supply. I had 2 on my eyelid years ago, and within a couple of days they turned black and fell off. Apple Cider Vinegar can do the job. Use a cotton bud to apply it. It's a good idea to put some coconut oil or vasaline around the base of the wart/tag to protect the skin.

**Q: Can you use near metal fillings in the mouth**
A: Absolutely it Is very good for sore gums.
