Thank you! I've heard gold is used in shots for rheumatism, just wasn't sure it was the hydrosol.
After some more research it seems the gold hydrosol is a bit more difficult to make at home although the silver version sounds doable. Some warn against using saline. It's recommended to use it on one hand because it's a conductor but then others say that wouldn't make silver hydrosol but silver chloride. Making it without the saline would take a bit longer but might be safer. I'm not sure I understood properly though, I'm quite a dummy as far as chemistry and physics are concerned. I know it can't be a miracle but perhaps it's of some use.
My mom used to persuade me to try an old wives tale. She said using a silver spoon used to be considered beneficial for children because it was believed silver would kill any pathogenic organisms. I just read a chemistry student's comment that sucking on a silver spoon could have similar effects as the hydrosol. That sounds whacko . Really curious what it's about though so I'll probably give colloidals a try and report back in a while.
