A great natural remedy to help treat an inflamed wound and with pus (abscess) is the clay poultice.
The clay cataplasm will act on the abscess making scarring faster.
Just buy a packet of green clay at a health food store and put only two tablespoons of the clay in a glass or plastic container and add some water until it's like a paste.
Next, under the wound, place a clean, permeable cloth and apply the poultice in the region, letting it act for a few minutes, then washing.
Repeat this procedure two more times and finally wipe the wound very well.
