Very impressed! ### ⭐⭐⭐⭐⭐ Review *by L***H on 7 May 2025* Seit ich es benutze, merke ich eine spürbare Verbesserung meines allgemeinen Wohlbefindens. Einfach und effektiv! ### ⭐⭐⭐⭐⭐ Review *by W***E on 10 January 2026* Works for poison ivy! It actually disinfects, or cleanses so to say. We’ve cleared bush with pioson ivy growing rampant and even dressing up to the core, we still get some. The sooner you spray it on your itch, the better it works! Once you notice you have a slightly itchy spot, spray it! Once it breaks out it will definitely help, but not nearly like right away! The first summer we lived in the bush, I dealt with poison ivy the whole summer! I’m still careful to not come in contact with it, but I still get it, and on first response I use the spray! Up to 3 times a day or so and for only a few days instead of bearing with it for a few weeks! ## 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.co.uk/products/381038246-premium-colloidal-silver-40ppm-34-fl-oz-optimal-concentration-formula](https://www.desertcart.co.uk/products/381038246-premium-colloidal-silver-40ppm-34-fl-oz-optimal-concentration-formula) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-22*
