I have heard about sodium thiosulphate being used for removal of heavy metals from the body. Aparently, there is a fungus in the blood called candida that absorbs it. But, too high a level of the candida can cause cancer. So, one has to kill the candida off and have something there to bind to the lead that will flush it out of the system.
As for peer reviewed research that curseyou mentioned, having seen the politics of peer reviewed research, I'd discount much of it outright...
Example. My last ex's father was a fancy biologist in a cancer research lab in Montreal area. He was required to publish a paper every so many years (think it was 4 or 5). So, he felt like he was near to a major breakthrough to a possible cure. So, he wrote a paper that told about his findings that were repeatable. They told him to change his paper and remove many of those things, because much of several reasons. Funding, it didn't fit the narrative that was wanted to be portrayed, and possible elimination of jobs in the cancer research institutes worldwide. Apparently, cancer research is a major industry worldwide, and the companies/institutes/foundations that get donations for 'research' would lose a lot of money if cancer was cured. We can't have the higher ups in the charities that you give money to having to stop living high off the hog because donations dried up because people are no longer afraid of cancer...
I read through his papers, both the original one, and the one as it was published. One did not resemble the other.
Having talked to other scientists in research, it's a fairly constant story. Even if they won't outright admit it.... Instead of looking further into anomalies, they disregard them, because these anomalies are harmful to the narrative that the group/company that is providing the funding wants portrayed...
My BiL is in pure research. So, I ask him about his research some times, and ask what he's trying to prove, etc. Then I ask him about what is disregarded. So, he'll tell me about a lot of stuff that's just tossed. So, I ask him, if these are actually constants, and not anomalies, would the theory have to be changed. He says yes... So, I ask him why he's disregarding it, and he always has the same answer. They'd lose their funding for the project. Here's the big problem that I have... he and any of his colleagues I have talked to have no problem with bought and paid for results. As long as they're getting paid, it's all good...
Let's look at medical tests... When a new drug is in human trials, there is a certain amount of side effects that are considered acceptable... But the companies doing these tests seem to not have a problem dropping people off the tests with the claim that they turned out to not be a suitable candidate for various reasons. Too high of a list of side effects in a patient, patient not responding to treatment as it was thought they would, etc. That's why there are so many lawsuits against drug companies in the US these days...
Anyways, with so called peer reviewed research, I'm of a very skeptical mind. These days, I"m more interested in what they disregarded that what they actually claim that they found...
