Contact with poison ivy usually causes a swollen, itchy rash that can blister if it's severe. According to the book "Folk Remedies That Work," the plant contains an oil called urushiol that causes the allergic reaction if you don't wash your skin with cold water immediately after contact. There are several popular home and over-the-counter remedies for red, inflamed skin caused by poison ivy. However, you should consult with a doctor before using these treatments.
Aloe Vera
Aloe vera contains antibacterial and anti-inflammatory compounds that, according to the book "1,801 Home Remedies," can reduce swelling and redness related to poison ivy rash. If your rash is fairly new, it can also keep the area from blistering. Slice a leaf off of your aloe vera plant and squeeze the gel from inside the leaf into your hand. Gently massage the gel into the rash, and make sure to wash your hands thoroughly with cold water and antibacterial hand soap afterward to keep the rash from spreading. Repeat the treatment every two to four hours. Aloe vera is not appropriate for severe rashes with blisters.
Vinegar Compress
White vinegar can dry out your rash and relieve itching. However, it can also burn broken and irritated skin, so this home remedy is really only for fresh rashes that you haven't scratched. Mix 1/2 cup of white vinegar with 1-1/2 cups of cool water and refrigerated the mixture until it's cold. Soak a soft, clean washcloth in the vinegar solution and apply it as needed to the rash.
Calamine Lotion
Calamine lotion is one of the most popular over-the-counter remedies for poison ivy rashes, and it's one of the few treatments appropriate for rashes that have begun to blister. Apply the calamine lotion according to the instructions on the packaging, thickening it with a pinch of cornstarch or baking soda if you prefer a more pasty consistency. Calamine lotion helps dry up pus and blisters, and is appropriate for more severe cases of poison ivy. However, if it's having no effect on your rash, you should see a doctor immediately. You may be having a serious allergic reaction that requires prescription medication.
