Yes, the 20%. I've found it on Amazon for as low as $6. A jar. We always use it first on nasty wounds. It gets the wound bed nice and clean & makes the horse easier to handle because it helps ease pain.
Here's an update on the filly. The bruise is starting to grow hair, and not as tender. Exercise helps a lot. She's sound. Not looking her best, as she's in a rough, range-y growth stage right now. She'll get prettier and shinier soon. I don't want her getting too fat right now, as I'm about to start riding her, so I'll keep her a little lean, then put weight on her. She'll be fat and sassy soon enough.
