Epsom salts will pull out infection from wounds in scalp infections. I mixed it about 1/2 cup of epsom salt to 1 quart of hot water.
Submerge infected area in solution 4 times a day. If unable to submerge area, just use washcloth to dip in solution and apply over infected are (hot compress method) 4 times a day. I have seen this cure infection after red streak was running up arm (indicative of blood poisoning). No antibiotics were needed. I have many times bathed in 1-2 cups epsom salts in hot bath when muscles or nerves said "help".You really feel relaxed.
I have also used a saturated solution of Apple Cider Vinegar and epsom salts to clear up deep infected ulcers in scalp; No antibiotics were needed. Swab ulcers.
