I have done a huge amount of research on holistic medicine and diets etc, I have bought some from my local health food shop but apparently Colloidal Silver kills ALL bacteria and viruses, if that is the case then antibiotics that people are starting to become immune from and which has been reported in the UK recently, that could be the answer to the antibiotics not working, I have a friend that every time they have a cold, the flu or a sore throat, sprays a little in the mouth and the symptoms disappear over night every time without fail. Anyhow, I know you can ingest it but I am trying to find out how much you can take without taking too much because of not knowing any side effects if there are any. You can however use it on the outside of the body and hospitals and surgeries in the UK are starting to use it this way with great success.
You can also buy colloidal gold which is ruby red in colour rather than the silver being clear, that can also be used as an anti inflammatory and can completely rejuvenate the whole body, I am researching this also and have found a Scottish company that makes and sells it so will buy from them over the internet and try it for myself.
Look into to it yourselves and maybe try it out but just make sure you buy it from a reputable company and know its a legitimate product, the UK have the most strict trading standards in the world hence why I am buying from a UK company.
I would be interested in any successes anybody has so please let me know.
