Green Tomato: Green (unripe) tomatoes contain a compound which perfectly neutralizes the toxin found in the poison ivy plant. It can be rubbed on the skin if you know that you recently came into contact with the plant (and thus absolutely prevent a reaction) or, if you have a full-blown case of the oozing pustules (yum), it can cure them pretty quick. Just cut green tomatoes in half and rub over the affected area. If the sores are already present, do this 3-4 times the first day and once or twice the second day. Just use freshly sliced tomatoes each time. The itching will soon stop and the sores will begin to quickly dry up. I've had people come back and hug me for this tip.
