Why is Ferric Chloride no longer used to stop bleeding in wounds?
My grandfather worked in the jungle for a mining company when he was young. In his first aid kit, there was always a small bottle of a black liquid that stung like hell but would seal any superficial wound instantly.
Over the years, he made sure we always had a bottle at home. When I was a kid, I cut my finger and it was starting to turn into an ulcer; my grandfather applied that liquid with some gauze. It stopped the infection right away, although it did leave a nasty scar.
He passed away a while ago, and when I tried going to pharmacies to ask for Ferric Chloride, they didn't even know it existed. Every time I see a doctor or a nurse, I ask them about it, but none of them seem to know what it is either. When I look it up online, the only results I find are about using it for etching metal...
