Therefore it also works for poison ivy, oak and sumac. There was a very helpful comment about the urushiol being the active agent and once that is washed off (of everything!) the clear fluid from the blisters is not an irritant. Thankfully I just got a very mild case (through a hole in a jersey glove I think) between my middle and ring fingers on one hand. I just ran a trickle of hot tap water over it as long as I could stand it a few times (maybe I only needed to do it once ;-) and that was way hot enough to assuage the itch, again for several hours.

You are correct in your assumption. Oddly enough, I got the info straight from a physician, which you would think would try to prescribe some medication to help fund the medical establishment. This is how it was described to me and the reasoning behind why this works. Get the water as hot as you can stand, without burning yourself. (I have a higher tolerance of pain and have burned myself in the past, but over time, worked out the perfect temp. ) What the hot water does, is releases the histamines in that area of your body, that is being treated. Our body has an allergic reaction to the ivy. With allergies, what do we take? Anti-histamines. So, with the hot water releasing these histamines, that cause the allergic reaction, there is nothing there to cause the itch. I was told that it can take your body, on average, 4-8 hours to replenish the histamines in the applied area, so it depends on the person I suppose. My own personal experience, I get relief from the itching for about 8 hours. When it starts to flare up again, another hot water treatment. Another interesting thing occurs too. The use of the hot water tends to dry out the affected area as well, thus the reaction to the ivy only lasts 3-4 days and it's gone. The drawback to it though, is now you've got dry skin for a few days. I don't experience that too often, but it does happen on occasion and really isn't a big deal to me. But, you could use lotion if you were so inclined. What used to be an 8-10 day irritation, aside from the frustration of trying every over-the-counter method to no avail, is now completely gone within a 3-4 day period. Plus, water is much cheaper than anything else you purchase. I used to hate mowing the grass or working in the yard, due to the ivy that grew along my fence. Now, I go at it with wreckless abandon, not worrying about the ill effects of the reaction, because I've found the perfect way to take care of the problem. IT WORKS! Besides that, what have you got to lose, water is basically free.Replied By Mountanpalm (Boone, Nc. Watauga, Usa) on 09/04/2011
So happy to find another living being that is on the same page as I am. Found this "hot as you can stand" remedy on the internet ten yrs. ago..... I stand by it today. I must have a high tolerance....... As people flinch when I explain the process....... I no longer do the "bathtub'.... Instead the shower...... Which you can regulate better when you get to the point of "intolerance" and move out of the way alot faster..... I get the same sensation as a good "scratch of the itch"..... With the hot water..... And revel in it. (sick, I know, but "ahhhhhh") But it works...... Lasts for 6-8 hours... Itch free for 8 hours........ I'll take it anyday. NOTHING over the counter works this good... I also use calamine to quicken the drying process...... Thanks for your comments!! [I am suffering from a terrible case as I write this......... But there is light.... at the end of this tunnel.]Replied By Jim (Cabrera, Dominican Republic) on 07/23/2012
This is a great description of how to use the HOT water method. It works for me and takes away the itch instantly for long periods of time.
