I tried this for my daughter who was bitten and I found out about it a day later when the site was swollen, huge and warm to the touch. I applied the bread, wrapped to her in an ace bandage and this morning when I removed the bandage/bread all had come to the head and drained out. She said it no longer hurt or irratated her.
Bread cured my daughters spider bite. Went to doctor who put her on anti-biotics. It did nothing for her. My wifes grandma told her to put a piece of bread on it. She did and it drew all of the puss out and cured it in one night.
