Here in South Africa it's usually called supona, a very common and quite effective spray-on for wounds. I find it quite effective especially for minor wounds, cuts and scrapes. For the more serious wounds I personally preer a thing called "wound magic" a Zinc ointment based wound salve that really has done wonders for some of my horses. A very good home remedy we often use and REALLY works miracles are Peach Tree leaves. If you have access to a peach tree take a handfull of leaves, crush them lightly, throw in a pot of water and boil for a few mins. Just about 5 mins or so. Put in a spray bottle and spray on any wounds, any animal. We had a piglet once, cut it's neck badly on a piece of plastic, put some peach leave extract on his neck, two days later it was completely healed.
