Does table salt promote healing from fin rot?
I would not use table salt, which can conmtain lots of iodine and lacks many trace elements including potassium. I would use regular aquarium rock salt, and yes, it does a great job of promoting healing in any external injury or disease, provided the fish in the tank are not too salt-sensitive. Salt should be added slowly to the tank in a solution form dissolved in water. Typical dosage is a tablespoon per ten gallons.
