You posted, "Let's hear your best poison ivy, poison oak stories" so here goes.
Todd was a teenager who used to come visit me. He came by with the worse case of poison oak we ever saw. I opened the Bible to James five, laid it open on the table and said,
"Take a look at this page," wanting him to find James 5:13-16 for himself. It says,
"Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing praises. Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, having anointed him with oil in the name of the Lord; and the prayer of faith will restore the one who is sick, and the Lord will raise him up, and if he has committed sins, they will be forgiven him."
He read silently down the page, and said,
"If that's what It says, that's what It means. Who are the elders?"
"I don't know," I responded. I remember thinking I couldn't be very 'elder' at the time; being only thirty-four years old.
"Well you're the oldest one here," he indicated.
"Pat, you're the next oldest, come join us," I requested. I don't remember if we used olive oil, cooking oil or motor oil at that time, but after this incident there was always some olive oil available. I poured some oil on his head and Pat and I laid hands on Todd and prayed for God to heal him. We didn't see an immediate change. About an hour later Todd excitedly said,
"Look at this! The poison oak's gone!"
Another fun story is when I first heard of homeopathic medicine. I figured what the heck. It sure can't hurt. My aunt was a nurse at the time and told me, "That stuff doesn't work." I followed the directions carefully. The next I was in the poison oak I was careful but not as careful as normal. I didn't get it at all. The next time I was not careful at all and didn't get it. After awhile I became so casual I forgot all about it. In fact one time while looking out over a clearing I grabbed a leaf from a nearby plant to chew on. Then I noticed it was poison oak. Never bothered me.
If I stopped taking it. I got the rash bad.
