Most people associate the application of oatmeal to a case of the chicken pox, but hives that appear as a result of an allergic reaction are quite similar to the itchy spots of chicken pox. You can make a small amount of oatmeal and refrigerate it, and then apply it to the site of the hives. The nutrients and minerals in the oatmeal can soothe the inflammatory response of the histamines and eliminate your desire to scratch the site of the rash. You can also draw yourself a full-size oatmeal bath if you have a larger outbreak of hives as the result of allergic exposure.
