The medical term for hives is urticaria. Hives are itchy raised areas that develop on the skin. They may vary in size and shape, and usually appear red. Hives many either develop in round patches or ring formations. They can occur on any area of the body such as the arms, trunk, legs and even the face. Hives are caused due to histamine and certain other compounds which are released by the mast cells of the body. Histamine results in leakage of fluid from the blood vessels in the area, thereby leading to swelling. Hives are a fairly common condition and usually resolve in a few weeks time. Although they are not a serious medical condition, they can be bothersome due to the itching and irritation they cause.
In some cases, hives result from allergies to certain foods, insect bites or stings and medications. Most cases of hives, however, are not due to allergic reactions and their exact cause is mostly never found. Some hives are hereditary and in rare cases these may be accompanied by breathing problems and shock. Hives are generally classified into two categories, ordinary hives and physical hives. Ordinary hives may develop for no apparent reason and welts and lesions may occur in many parts of the body. These may then subside in a short period of time and recur elsewhere on the body. These hives may be caused by viral infections or intake of certain medications. Physical hives are caused by physical stimulation of the skin such as rubbing or scratching. This direct stimulation of the skin results in leakage of histamine, resulting in the development of hives.
The most effective way to alleviate the discomfort caused by hives is to apply cool compresses. Taking a cool bath or shower would also help in reducing itching and swelling. Vitamin E oil may also be applied to the affected areas twice a day. Itching and irritation is often effectively reduced by applying a mixture of baking soda and cornstarch. One could also add this mixture to a bath and soak the affected areas in it for a few minutes. Herbal teas are known to work well in treating hives. Drink teas such as chamomile, valerian or peppermint tea for relief from hives. Another home remedy for hives is aloe vera. Apply the gel from aloe vera leaves to soothe itchy hives. Increasing the intake of foods high in vitamins C, E and zinc is also known to help in treating hives.
