A really great home remedy for irritated skin like sunburn or poison ivy is milk and water compresses. It's very simple. Put equal amounts of milk and water in a bowl, room temperature, take a smooth material like a T-shirt or handkerchief, put it in the liquid, wring it out half-way and apply it to the irritated skin for about 5 or 10 minutes. The evaporation of the liquid causes a cooling sensation, makes your skin feel better, and the protein in the milk buffers the irritated skin and goes a long way toward making it feel better. And by the way, use skim milk, not whole milk, because the fat in whole milk doesn't help, it's just the protein in the skim milk, and you'll find relief every time.
