Interesting idea. After posting the thread, I also had the thought about the herbal correlation and how could they be enhancing by breathing the corrispondent planetary energy into them. I read that historically colloidal gold was taken daily in Egypt which could be an allegory to solar energy of course, but I think it's also physical, given the immense benefits of colloidal gold that support students, athletes and workers alike.
I've recently read about colloidal platinum, colloidal palladium and colloidal iridium. The interesting thing about platinum, aside from the benefits, it's its alchemical symbol, which is the Moon symbol next to the Sun symbol. So I thought it could be an allegory for the lesser rainbow body (astral immortality.) Of course, you're not going to become immortal by using colloidal platinum. I'm not saying that, I'm shedding light on alchemy. Interestingly enough, the effects of colloidal platinum seem to relate a lot to spiritual skills like lucid dreaming, enhanced ESP and so on.
Now, of course we know mercury and lead are not to be intaken as that leads immediately to disaster, given their toxicity. However, we take iron as a mineral supplement, so I don't see why a colloidal form couldn't be more effective. I don't know anything about tin and whether it's toxic or even exists as a sol.
For those who don't know what a colloid means, it's a term that comes from chemistry. There are different types of colloids. Here's an explanatory picture:
