Neem oil is a true gift from nature. I use it in my hot spot salve along with a bunch of other oils.
Hot Spot Remedies: My dog Terra who is part Sheppard and part Akita, had two large hot spots on her back above her tail. I wasn't sure what to do so I asked the folks at our local herb shop ( called "the Herb Shop") and they recommended using Neem oil. When I got home I poured a little Hydrogen peroxide on them to clean and disinfect the spots and then I applied a coating of the oil, nothing else. After about 20 minutes or so, the skin started drying out and that was it, no more problem , completely healed with in a few days.
Several years later, my Mother was in the last few days of her life, from cancer, and we noticed a rather large bed sore on her back so I applied some Neem oil and the same thing happened. Even though her body had started shutting down the skin was reforming on the bedsore!
