Silver is a relatively rare metal that would almost never find its way into the human body in any meaningful quantities in real life. It has no known function in the human body (or I'm pretty sure in any vertebrate bodies). How the hell would your immune system's strength be based on a mineral that human bodies are almost never exposed to in reality?
Breh, the guy I quoted said she was "instantly healed". If you're just supplementing your immune system then you ain't getting "instantly healed". Bring it up with him, not me.
"can easily google" - I google and see dozens of sites confirming that people can turn that color for real
"eliminates from any conversation about anything scientific" - those google results include numerous scientific sites
I think our teacher has the "only quacks and profiteers" version of google.
This is Stan Jones, well-known Liberatarian politician, in the public eye for 20 years, it's easy to find before and after pictures.
"Associated Press Libertarian U.S. Senate candidate Stan Jones, speaks Sept. 23, 2002, during a debate at the Great Falls Civic Center in Great Falls, Mont. Jones has a distinct blue-gray skin color, the result of taking too much of an anti-bacterial form of pure silver. Jones said he started taking colloidal silver in 1999 in preparation for what he feared might be Y2K disruptions that could lead to a shortage of antibiotics."
You can read about him in the BBC, but if you don't trust that then even pro-silver sites like
Colloidal Silver Facts and
Sovereign Silver confirm his story.
Other scientific sites:
WebMD: "Argyria is a rare
skin condition that can happen if silver builds up in your body over a long time.
It can turn your skin,
eyes, internal organs, nails, and gums a blue-gray color, especially in areas of your body exposed to sunlight. That change in your skin color is permanent."
Wired.com "The disorder is caused by excess silver ions in the body, which react when exposed to light (the same phenomenon that makes silver nitrate useful for developing photos) and form dark deposits in the skin. It’s a rare but irreversible condition, and in most cases the culprit is overenthusiastic use of colloidal silver."
Science Daily "Researchers have shown for the first time how ingesting too much silver can cause argyria, a rare condition in which patients' skin turns a striking shade of grayish blue."
Live Science "Homeopathic medicine, colon cleanses, juice fasts: Of all the unproven health remedies, one of the weirdest may be taking colloidal silver. People drink the silver solution in an attempt to keep infections at bay, but those who drink too much turn a disturbing shade of blue-gray, a condition known as argyria."
Chemistry World "Scientists have put forward a
detailed biochemical model to explain
argyria, a condition which turns sufferers' skin a distressing blue colour. It is caused by chronic exposure to silver and although the new work won't lead to a cure it does provide new insights into the health risks associated with silver nanoparticles that are now ubiquitous in modern life."
Smithsonian Mag "For the first time, researchers have figured out how silver can permanently turn a person’s skin into a striking blue-grey color, causing a condition known as argyria"
And finally,
a summary from the Mayo Clinic:
"Colloidal silver isn't considered safe or effective for any of the health claims manufacturers make. Silver has no known purpose in the body. Nor is it an essential mineral, as some sellers of silver products claim.
Colloidal silver products are made of tiny silver particles suspended in a liquid — the same type of precious metal used in jewelry, dental fillings, silverware and other consumer goods.
Colloidal silver products are usually marketed as dietary supplements that are taken by mouth. Colloidal silver products also come in forms to be injected or applied to the skin.
Manufacturers of colloidal silver products often claim that they are cure-alls, boosting your immune system, fighting bacteria and viruses, and treating cancer, HIV/AIDS, shingles, herpes, eye ailments and prostatitis.
However, no sound scientific studies to evaluate these health claims have been published in reputable medical journals. In fact, the Food and Drug Administration has taken action against some manufacturers of colloidal silver products for making unproven health claims.
It's not clear how much colloidal silver may be harmful, but it can build up in your body's tissues over months or years. Most commonly, this results in argyria (ahr-JIR-e-uh), a blue-gray discoloration of your skin, eyes, internal organs, nails and gums. While argyria doesn't usually pose a serious health problem, it can be a cosmetic concern because it doesn't go away when you stop taking silver products.
Rarely, excessive doses of colloidal silver can cause possibly irreversible serious health problems, including kidney damage and neurological problems such as seizures.
Colloidal silver products may also interact with medications, including penicillamine (Cuprimine, Depen), quinolone antibiotics, tetracycline and thyroxine (Unithroid, Levoxyl, Synthroid) medications."
