i, personally, have found, that metal detox can be more hazardous than low level exposure. exposure causes a build up over time. the body does it's best to deal with it. it excretes some, it stores the rest, some by itself, but also with help from the microorganisms that live in us. this is apparently, playing at least some part in the increase in fungal and bacterial overgrowth, that is plaguing many people today. killing these things off too quickly, releases the toxins their overgrowth was meant to control.
excretion can only take place at certain rates. releasing toxins from the tissues faster than the body can remove them is dangerous. the rates can be altered by using binding materials and by altering the modes of excretion. i am working to put together a post containing some of what i have gathered. detoxification seems to be a widely misunderstood subject. i struggle to make sense of all i have found.
i, personally, have experienced symptoms of barium toxicity. i have found relief with epsom salts. i have used them in baths, and even taken a teaspoon with water. this is what i have done. i cannot legally recommend anything to anyone else. i am, as yet, unsure if my improvement was due to the magnesium or sulfur, or both.
i am still researching aluminum. i have found scientific papers describing the use of alfalfa in removing metals, including aluminum, from wastewater. i have also found seaweed(not listed what kind) used for water. what works for wastewater, may not work for humans.
excretion of toxins takes place by kidneys, colon, mucus membranes, tears, hair, nail and skin growth, and sweat. i try to protect my kidneys from any of this. from what i have found, sweating i believe to be the easiest and least dangerous, provided, i don't overheat myself. overheating the brain is dangerous.
far infrared sauna increases sweating without significantly increasing ambient temperature.
i, mostly, use sunlight. this has many beneficial effects for me. it improves my mood and increases my vitamin D sulfate, all the while increasing sweating. i am careful not to burn.
