Poison Ivy Rash Treatment
Poison ivy is a plant native to North America, where it can be found in most regions, except those with extreme heat or cold. It is a wild, woody vine whose leaves and stems contain an oil called urushiol, which can cause a severe allergic reaction on many people’s skin. This reaction can cause symptoms such as intense itching and rash. In more severe cases, blisters appear that may release a clear fluid. However, the symptoms of poison ivy allergy occur only 12 to 48 hours after your skin touches the plant. During this time, an individual’s skin, clothes, and equipment may also carry the urushiol, which is odorless and colorless. This increases the risk of the oil spreading to several parts of the body, or contaminating other people. It is recommended that all clothes and equipment be isolated and washed immediately in any cases of suspected poison ivy exposure. Any skin exposed to poison ivy should be washed under running cold water at the earliest, and with soap and water if available. This helps to remove urushiol from the skin, reducing the intensity of the allergic reaction.
While the rash can be quite uncomfortable, it usually disappears in around two weeks as the skin’s allergic reaction fades. At home, treatment is usually focused on reducing the inflammation and providing relief from the itching. Over-the-counter hydrocortisones can help in mild cases, but more severe reactions (especially those that develop blisters) need to be examined by a doctor, who may have to prescribe oral corticosteroids and antihistamines. If blisters develop, do not touch them, since they form a natural bandage and protect the damaged skin tissue. A simple cold compress can be very soothing and helps to numb the areas affected by the rash.
Home Remedies for Poison Ivy
Calamine lotions or petroleum jelly can also help to cover and protect the inflamed skin. Aloe vera gel is especially useful, since its antiseptic qualities help to prevent secondary infections in the affected area and it speeds up the skin’s healing process. In cases where the rash is widespread, taking a bath in water containing sea salt and medical oatmeal preparations (available at drugstores) can provide much relief. Some people prefer to apply a paste of baking soda and water to the rash, since this is believed to reduce the inflammation and protect the skin. Another popular home remedy involves rubbing the affected skin with the insides of banana peels, which has a cooling effect.
