I tell everyone about it. I use it on minor burns, cuts, sore throats. During the summer it helped with the itchy throat I get from hayfever. It also helped cool down my heat rash. I spray it to even keep me cool. It has so many benefits I keep it with me at all times. I take it with me abroad it even stops the itching after a mosquito bite. Absolutely brilliant! Review: Why did I not know about this until now? - In a casual chat with my brother on the phone I mentioned that our crazy labrador puppy who is ball bonkers kept getting grazed elbows as she loves to go into a sliding skid to catch the ball when we we throw it. He said "oh you need colloidal silver" just spray it on the sores and they'll heal in no time. I then did a bit of research and read all the great reviews and all the things colloidal silver could be used for. I immediately ordered some and I have to say it does work a treat on the dog's sores. I just spray it on and she has stopped over-licking them now too. My daughter has started using it as a topical application and swears her acne patch on her forehead is much better and I've been using it as both a face toner (spritz) and throat spray. I am amazed I have not heard of this miracle product before - its brilliant and is now my go-to product for well just about every ailment. I scratched my hand gardening and immediately sprayed the wound with colloidal silver. I swear it took the sting away immediately and healed in no time. I've always been a good healer but I definitely think this speeds up the healing process and the anti-bacterial properties are a bonus. I've just ordered a second bottle so I've definitely always got some in. The only criticism I would make is how difficult it is to decant from the large bottle to the small one without spillage. Think I'll need to invest in a tiny funnel to help. ## 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.

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. ## 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.jp/products/102114973-colloidal-silver-bottle-300ml-and-spray-30ml-to-fill](https://www.desertcart.jp/products/102114973-colloidal-silver-bottle-300ml-and-spray-30ml-to-fill) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-27*
