What Are the Symptoms of Antimony Poisoning?
Antimony is in the same chemical group as arsenic, another metalloid mineral.
Thus, many of the signs and symptoms of antimony poisoning resemble those of arsenic intoxication:

•Small doses or limited exposures to antimony and its compounds can cause depression, headache, nausea, or dizziness.
•Acute exposure to large doses usually causes severe vomiting, abdominal pain, diarrhea, and numbness or tingling in the extremities.
Left untreated, significant intoxication can cause death within a few days.
•People who are chronically exposed to relatively low doses of antimony can exhibit varying degrees of the abovementioned symptoms.
Additionally, they may experience hair loss (systemic exposure) or a thickened, scaly rash called lichen planus (skin exposure).

Of course this concerns me as she has had some rashes and abdominal pain and explosive bowels, diarrhea ect..
She was in stomach gas pain one night pretty bad..
And in a very highy upset & aggitated state..
Her mouth is red all around it and up one cheek constant licking , though it's alot better now.
She has Antimony at high levels coming out for sure.
So I assume that it is causing this for her.
Antimony is never good to ingest like good for you..
I believe..
It's not easy to get out either she is chelating..
To get it out..
