Still not very expensive and clearly it worked for the OP soooI also question the purpose of using moisturizers on a wound .
If you don’t want to use it that’s fine but it clearly worked for them so there’s no need to bash it. Or act like it costs $500 or something. I found it for $4 plus shipping. And even at $20 that’s still cheaper than a $200 vet bill.
Maybe epsom salt is even cheaper but maybe some people would rather pay and use this
Just cause you wouldn’t doesn’t make it wrong.
