Natural Remedies for a Brown Recluse Spider Bite

I work in a school cafeteria. We have had the same gentleman exterminate our kitchen for years. One day he, another co-worker and I were chatting. He mentioned he had been bitten by a brown recluse a few years back. He was at a clients house when she noticed the bite. She asked him if she could try an old home remedy that was good for spider and insect bites. He agreed and she went to her kitchen and made a paste of flour and milk. She then proceeded to mix in nutmeg till it made a "tan" color. She applied the paste to the area and he went along his way. By the next morning he said all that was left was a pimple. No pain, swelling, redness, fever, nothing but the pimple.
