Prussian Blue

Prussian Blue is a dark blue pigment created through a chemical reaction between iron salts and cyanide compounds. It appears vibrant blue and is used in various applications, including art and medicine. Medically, it functions as an antidote for certain types of poisoning, such as with radioactive or toxic metals, by binding to these substances in the body and helping remove them through waste. Its stable, non-toxic nature and strong color make it valuable both aesthetically and therapeutically.
