Antiseptic Fomentation (for dogs and cats) 1 part chamomile 1 part red clover 1 part comfrey root 1 part thyme Herbs may be used fresh or dried. Mix together. Make a strong infusion. Dip muslin or wool cloth into hot liquid, and apply to sore or inflamed area. Keep the fomentation hot and apply repeatedly. The fomentation will help bring the infection to the surface, and if a scab is present, it will come loose easily and the wound will drain. After the wound has been opened and drained, sprinkle Antibacterial Powder on it.
