We use sugar or honey with iodine for wounds. Preparation H to reduce swelling around the wounds if needed. We've had some really awful wounds, due to some careless hunters, heal with virtually no scars. We used to use Used Motor Oil for the horses hooves but it has soooo many additives in it now I wouldn't use it on a triple dog dare. A cheap and super easy way to get the "Witches Knots" out of manes and tails is to put 3 parts and 1 part Corn Starch in a spray bottle. Spray into the knot. Let set for a couple of hours to really work in deep, if needed. Then comb out.
