I was today searching the internet for Thornit ear powder and came across the following recipe.
Make up your own version of Thornit with ingredients from your chemist.
4 oz. zinc oxide powder
4 oz. boric acid powder
1/2 oz. Iodoform powder
Mix well. Keep in a sealed jar in a cool dry place.
How it works
The iodoform powder kills anaerobic bacteria and fungi which flourish in warm, moist, airless places. The zinc oxide and boric acid keep the ear dry, which prevents further infections. In the days before antibiotics, Iodoform was frequently used in human medicine to pack puncture wounds where anaerobic bacteria also grow. It may be hard to find because it isn't used much any more.
Does anyone know if this is a accurate recipe?
