Poisonous antiseptic
During the decade, Mercurochrome was once a popular over-the-counter medicinal product that was used as an antiseptic. It was usually applied to cuts, scrapes, and the like despite the solution containing mercury. This is why it would stain the skin red, which made it difficult to detect infection or inflammation. The solution could also harm fetuses in pregnant women. Nowadays, Mercurochrome is no longer available at any United States drugstore. It’s a good thing that we’ve come to our senses.
