I was introduced to colloidal silver about seven or eight years ago. I am no doctor or expert on alternative medicine, however, I am a huge fan of colloidal silver. It has definitely worked for my family abd I. I love the Sovereign Silver brand. I have been buying this specific brand for about five or six years now. I get the dropper version of this as well as the spray. I have tried a different brand in a gel form but it is hard to find and didn’t work as well as the spray or dropper in my opinion. I have read articles and seen videos on people turning blue (hasn’t happened to me thankfully ) and people or health professionals saying the claims of healing are false. I can’t speak for those people or those studies but I can share my experience with you. If you use the proper dose, then you won’t likely turn blue. If you use a reputable brand, then you probably won’t turn blue either. If you have any health conditions or take any medication, then consult a doctor or alternative health care professional that you trust to guide you. While I was sick one year, with what seemed to be never ending sinus infections, I went to a health food store as a last resort for relief. A friend told me to try some colloidal silver because antibiotics were not working. I thought she was nuts to be honest but I was desperate for relief and couldn’t call in to work forever. She had made two other recommendations from the same store before and it seemed like they help with other issues so I thought I would take my chances. I consulted with an employee in the store before getting the colloidal silver and he seemed to really be informed, so I took the plunge. Colloidal silver is antibactetial and antimicrobial. I can tell you I have never looked back. I cleared up my sinus infection and I have continued to use it for many other things with success. I have use the spray and dropper for sore throat, ear pain, diaper rash, cuts, eye infection, and just about anything you can think of. I used the nasal spray version for stuffy nose, sinus infection (as soon as there are signs and before it is too full of nasal discharge) and it worked wonders. It shortens the duration of these ailments and prevents thrm from taking a foothold. I used colloidal silver when I had strep throat(also used medicine from doctor because I didnt want to mess around with strep). I used it when I had a urinary track infection during pregnancy and my doctor was amazed at the results. I used it for pink eye and never needed medication. It really is amazing. It really has saved myself and my family tons of doctors trips and money. Definitely don’t skip the doctor if you are having issues or have conditions that could be life threatening but the silver can make a great partner for some conditions. In some cases it will allow you to skip medications and be rid of ailments permanently. Do your research before you buy this item.
