Baking Soda
Baking soda is the most common home remedy for itchy skin as well as skin rashes. Baking soda has a soothing effect due to its anti-inflammatory properties. Plus, it acts as a natural acid neutralizer that helps relieve itching.
Add one cup of baking soda to a bathtub filled with cool water. Stir it well to distribute the baking soda thoroughly. Soak in this water for about half an hour. Pat yourself dry instead of rubbing the skin with a towel. Do this once daily.
For more localized itching, prepare a paste by mixing three tablespoons of baking soda with one tablespoon of water. Apply the paste on the affected areas and leave it on for about 10 minutes. Do this once daily.
Colloidal Oatmeal
Colloidal oatmeal (oats ground into an extremely fine powder) helps soothe and comfort itchy skin. It contains anti-irritating, anti-inflammatory and soothing properties that provide instant relief from itching.
Add one to two cups of colloidal oatmeal to a bathtub filled with lukewarm water. Soak in this water for at least 15 to 20 minutes. Never use hot water as it may irritate your skin more. You can take an oatmeal bath up to three times a day, depending on the severity of your condition.
Add a little water to one cup of colloidal oatmeal and leave it until it thickens to a paste-like consistency. Apply this mixture on the itchy skin, cover it with a cloth and leave it on for half an hour. Follow this remedy once daily.
If colloidal oatmeal is not available, you can use unprocessed oat flour or whole oats that have been ground in a food processor.
Cool Water
The sensations of both cold and itching travel along the same nerve fibers in the body, so applying cool water on the affected skin can bring instant relief from itchiness. There are many ways to use cool water for itchy skin.
Run cool tap water over the affected skin for as long as necessary.
Rub an ice cube wrapped in a cloth over the affected area.
Take a cool shower or bath.
Apply a cold compress or cloth wet with cool water to the affected area.
Lemon
People have used lemon to treat itchy skin for ages. Lemon contains citric and acetic acids, which have great antiseptic, anesthetic, anti-inflammatory and anti-irritating properties.
Extract the juice from one to two fresh lemons.
Apply the juice on the affected skin area using a cotton ball.
Let it dry on its own and then wash the area with lukewarm water.
Repeat twice daily until the condition improves.
