Institut Katharos Colloidal Silver is a high quality brand which I have found to be very effective at what it does. Silver has been used for thousands of years for microbial infections due to its anti-bacterial properties. This particular brand comes with a handy little spray bottle which is of great use for administering externally. I have used this colloidal silver effectively to prevent infection in several ways as follows: ✅ Applied it topically on open wounds to clean and protect ✅ Used the spray bottle in nose and mouth as a preventative measure ✅ Applied on my cats paw when she had a cut ✅ Applied on cold sores ✅ Used internally to relieve infections My family have also used this product with success for some of these issues. Having tried a few brands of Colloidal Silver, I have been using Institut Katharos Colloidal Silver for 9 years now. It is a brand I completely trust and is a permanent fixture in my first aid box. Review: BRILLIANT, AMAZING PRODUCT. - This is an amazing product. My cat had some very nasty sores on the base of her back which we think were caused by an allergy to flea saliva. I wanted to try an alternative, gentler treatment than antibiotics or steroids. A friend recommended using Colloidal Silver, which I had heard of before. This particular one had good recommendations. Absolutely brilliant. Cat didn't mind me praying it on as does not sting. Within 7 days there was a considerable improvement and within 10 days, sores had completely healed. I sprayed 3 times a day, morning, mid afternoon and then bedtime, reducing down after 10 days to morning and night and 16 days on, just giving one spray at night. She's completely healed now. Bought the 300 ml bottle and used about 60mls, it goes a long way with the spray bottle provided. Husband and son have sprayed into their mouths when feeling a cold coming/sore throat and next day it seems to have gone. I cannot recommend this product highly enough and have ordered another bottle for a friend. Well done to this little French business for producing a clean, safe and effective alternative to chemical medicine. ## Features - ●●● POWERFUL COLLOIDAL SILVER ●●● Just two ingredients. Yes, really.

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: Can u ingest this and use it as a cleanse** A: Yes definitely as me and the dogs use it, did you read the ebook sent to your email? **Q: Has anyone got the correct link to the ebook the one I got in the little leaflet with this isn’t working** A: I didnt get an e mail and the address on leaflet doesnt work. I know they used this before antibiotics were invented in the first world war! ## Customer Reviews ### ⭐⭐⭐⭐⭐ A genuine and quality product from a brand I trust *by R***Y on 13 March 2026* I have been using Colloidal Silver for eleven years now and I would never be without it in my cabinet.

It's worked out a lot better than I imagined. For example: my mother's legs often come out in blisters and sores because of poor circulation (her legs aren't at the stage of ulceration - yet). Recently, my dog accidentally scratched one of her legs and I immediately applied the colloidal silver to where the scratches were to help clean it up and in the hope it would help it heal. After regularly spraying it on the spot (this was done, together with my sister's nursing of the same leg by other means) … it is on its way to getting better. I have used colloidal silver in products before (in hand wash and infused into sticking plasters); I bought a spray bottle of it in 2017 (of a different brand but with a slightly lesser concentration than this one). I initially bought it because it helped with fresh cuts or grazes to the skin or sore spots on human members of my family … I even used colloidal silver on my pet dog when a benign lump on her skin suddenly burst on Christmas Day 2017, not knowing whether it was the right thing to do as other stuff would definitely be harmful (NB: I explained to the vet what happened and what I did with the colloidal silver - he told me I did the right thing. Nowadays, there are ointments and other things for pets containing colloidal silver). I am delighted with this brand of colloidal silver and, when the current bottle is finished, I will purchase another from the same people in the very near future. ## Frequently Bought Together - Premium Colloidal Silver 40ppm 300mL ● Free Spray Bottle to Fill & Ebook Included ● Optimal Concentration Formula, Smaller Particles, Better Results ● Laboratory Certified ● Liquid Silver - Nature's Greatest Secret Antibacterial Multi-Purpose Gel with 98% Premium Quality Colloidal Silver 100g (packaging may vary) - Benatural Essentials Premium Colloidal Silver Aloe Hydrogel 100g | Soothing Gel For Minor Burns, Scratches and Rashes | Antibacterial & Antifungal | PH Balanced | Manufactured in the UK --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/102114973-premium-colloidal-silver-40ppm-300ml-free-spray-bottle-to-fill](https://www.desertcart.kg/products/102114973-premium-colloidal-silver-40ppm-300ml-free-spray-bottle-to-fill) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-21*
