Great stuff! From a long standing customer.
I have been using Coloidal Silver for many years. A friend first put me on to it, we both had horses and I was delighted to find this. I've since noticed that even the nurses use it on wounds, so I thought it's got to be good. At first I used it for my horses, now I no longer have them, I keep it for myself and the doggies.

Nova Sore Calming Gel - Excellent Product!
I have found the Calming Gel to be highly effective at preventing impending & healing longstanding cold sores on my lips. It is cooling, rapidly absorbed &left my lips soft & well moisturised. The cold sores did not develop as they have in the past. Made from largely natural products, so no nasties here. Friendly efficient service & quick delivery. Highly recommended!

Nova Sore Calming Gel
Nova Sore Calming Gel - Innovative & range development most welcome.
Not wishing to have any sores needless to say. I have used the gel on a couple of occasions when the lip-tingle suggests an infection is likely. The gel stopped the tingling and seemingly prevented any development of the infection.
So far so good. The bottle will remain on-hand, just in case.

I’ve been a loyal customer of this…
I’ve been a loyal customer of this company for well over a decade, and I can honestly say their service has been consistently excellent throughout that time. Both myself, my wife and our dog have benefited from the quality of their products, which have never let us down.
What really sets this business apart is their commitment to customer care. They genuinely value loyalty, and it shows — not just in words, but in how they treat you. On the rare occasion there’s been an issue, it has always been handled quickly, professionally, and without any fuss.
It’s refreshing to deal with a company that combines high-quality products with such reliable and friendly service. I wouldn’t hesitate to recommend them to anyone looking for a business they can trust long-term.

Enhanced benefits from colloidal…
We have been using their colloidal silver products for quite a long time, pre-Covid. When their latest cold sore gel was released we just knew it would be a great product. Proving to be so. Used it as soon as the irritation starts. Avoided the prolonged cold sore development.
