Very impressed! Review: Amazing Product and brand - I LOVE this product and I’ve recommended it to several other people. Sore throat— spray or gargle. Ear infection? Spray it or add a couple drops to the ear. Earrings caused slight infection to my ears. Sprayed some silver and it was better within a day. Fee a cold coming on, gargle/swallow for a couple days. Minor cuts and scrapes? Spray this on. Tastes like water at first but then has a different aftertaste (which my kids don’t necessarily like), but it’s tolerable and goes away quickly. Used for my dogs as well. I’ve used this for so many different things and can’t say enough good things about it. I wish I had known about it sooner. Worth every penny. The company is great and the quality of their product is top notch. I’ve purchased twice now. I highly recommend this brand. ## Features - ●●● BOOST YOUR IMMUNITY ●●● Let your body thrive with Institut Katharos’s colloidal silver.

We were so heartbroken...with these teeny little birds, the nearest vet to us who even knew anything about treating them was a couple of hours away. Poking around online revealed mites as a possible culprit, and colloidal silver as a possible remedy. It really did seem to help. They were fine for a long time, but then after the pandemic really hit they both started acting fussy and itchy again. I found this seller on Amazon. The first order cleared up the eye issues right away, so we slacked off on using it with our birds. We won't make that mistake again. One of them developed a frankly horrifying-looking wound near his eye from the scratching. We started using this stuff on them again, and I don't know how it works, but it works. It's just CRAZY how it works. His wound completely healed up! We add just a couple of drops in their water dishes each day, and spray them with it at least a couple of times a day. They actually really love getting sprayed. Y'all, these Zebra Finches are close to ten years old, which is ANCIENT for them. And they're doing great! I'll keep using this stuff on them! ## Frequently Bought Together - Premium Colloidal Silver ● Optimal Concentration Formula, Smaller Particles, Better Results ● Laboratory Certified ● Liquid Silver Made in EU ● Free Spray Bottle to Fill & Ebook (34 fl oz) - Silver Miracles - Colloidal Silver Soap - 3 pack - Pure Colloidal Silver Gel 40 PPM • 100% Natural and only 3 Ingredients • Optimal Texture and Absorption (Better Than Creams) • Amber Glass and Ultra-Practical Pump • Ebook Included • Institut Katharos --- ## 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.tn/products/184418109-colloidal-silver-bottle-34-fl-oz-and-spray-1-fl](https://www.desertcart.tn/products/184418109-colloidal-silver-bottle-34-fl-oz-and-spray-1-fl) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-07*
