Bed sore

My father who is 89 years old came back with a bed sore from the hospital in May.

I started him on tarantula, calendula, hepar sul and gunpowder with lycopodium and Silicea.

The below pic are taken on 17/5/22 before I started him on the homeos. The the after photo taken on 22/6/22. I also used gun powder directly on the would during dressing.
