Rashes, also known as hives, are skin reactions that cause itchy bumps due to an allergy to certain environmental substances, referred to as allergens. While the cause isn't always clear, it's a response of the body producing histamine when allergic to foods, medications, or other substances. Histamine may also be triggered by infections, stress, sunlight, or temperature changes. The rash often appears as small red, swollen, itchy patches on the skin, which can occur in clusters or individually. The rash usually fades within a few hours without treatment, although new rashes may appear in other areas. If you'd like to treat the rash on your own, various natural remedies are available.
Steps
Avoid Allergens
Understand the Cause of the Rash. Anyone can experience a rash due to an allergy, with about 20% of the population having had one at some point in their life. When allergic, certain skin cells like mast cells release histamine and other signaling chemicals like cytokines. These substances increase leakage from capillaries in the skin, causing swelling and itching, which are common characteristics of rashes.
Avoid Allergens. The first step in treating a rash is to make sure you have removed the source of the allergy. In most cases, people can identify the cause of their rash, so it's important to eliminate the allergen from your skin or environment. Common allergens include poison ivy, poison oak, insect bites, wool clothing, and pet dander. You should avoid these triggers as much as possible and any other allergens you're aware of.
- In some cases of chronic rashes, you may need to investigate the specific cause of the rash.
- Other common causes include food, medications, chemicals like acetone, natural rubber, viral infections, fungal infections, bacterial infections, pet fur or dander, and physical irritants like pressure, temperature changes, and sunlight.
Protect from Pollen. Environmental factors can sometimes trigger rashes. If you're allergic to pollen, you should avoid going outdoors during early morning and evening when pollen levels are highest. Keep windows closed during these times and avoid hanging clothes outside. Change into indoor clothes as soon as you get home and wash your outdoor clothes right away.
- Using a humidifier indoors can also help reduce symptoms.
- You should also minimize exposure to other common air irritants like insect sprays, cigarette smoke, burning wood smoke, tar smells, or new paint odors.
Use Localized Treatment Methods
Apply a Cold Compress. Since the main symptom of a rash is skin irritation, you need to treat the external symptoms to alleviate the rash. Take a clean cotton towel, dip it in cool water, wring out the excess water, and place it over the itchy rash area. Leave it on for about 10 minutes, then wet the towel again to keep it cool, which will also cool your skin.
- You can apply the cold compress as long as you like, until the itching subsides.
- Avoid using water that is too cold, as it may worsen the rash for some individuals.
Add Oatmeal to Your Bath. Oatmeal is one of the best natural remedies for itchy or irritated skin caused by a rash. Take a cup of raw, crushed oats and place them in a food processor or coffee grinder. Grind until the oats become a fine powder. After grinding, add one to two cups of the oat powder into a warm or cool bath, turning the water into a milky, smooth consistency. Soak in the bath for as long as you want, and you can repeat this process as needed.
- Avoid soaking in hot or cold water, as it may aggravate the rash.
- Adding up to four cups of milk can enhance the soothing effect.
Make a Pineapple Compress. Pineapple contains bromelain, an enzyme that helps reduce swelling caused by rashes. Crush some pineapple—whether canned or fresh—and pour it onto a thin towel. Gather the four corners of the towel and secure them with a rubber band. Press the pineapple-covered towel onto the rash area.
- If not in use, store the pineapple in an airtight container in the fridge. You can use it as needed but be sure to replace it after 24 hours.
- Alternatively, you can directly place pineapple slices on the rash.
- Bromelain is also available in supplement form, so you could take it to help treat the rash.
Mix a Paste Using Baking Soda. Baking soda is an effective remedy for itching caused by rashes. Mix one tablespoon of baking soda with enough water to form a paste. Start by adding a few drops of water and stir, then add more water if necessary. Use your fingers or a spatula to spread the mixture onto the rash-affected skin, and apply as many times as needed before rinsing it off with water.
- You can also use the same method with used wine dregs if available and apply it as many times as you wish.
Use Vinegar. Vinegar contains several beneficial nutrients that can help treat various ailments, and you can choose any type of vinegar you prefer. Mix one teaspoon of vinegar with one tablespoon of water and stir well. Use a cotton ball to apply the mixture onto the rash, which will help reduce itching.
Use Nettle. Nettle has long been used to treat hives due to its natural antihistamine properties. You can brew nettle tea, consume it directly, or take it in supplement form. To make a cup of nettle tea, place one teaspoon of dried nettle in a cup of hot water. Let it steep for a moment and allow the tea to cool before drinking. You can also soak a cotton cloth in the tea, wring out the excess, and apply it to the rash. Apply as many times as needed.
- For supplements, you can take up to six 400 mg capsules a day. If consuming nettle directly, it's best to steam it.
- Store any unused nettle tea in an airtight container in the fridge and be sure to make a fresh batch after 24 hours.
Apply Calamine Lotion. Calamine lotion is a mixture of zinc oxide and zinc carbonate, which is effective in treating itching, and you can apply it as many times as needed. Once the itching subsides or if you want to reapply, be sure to first wash off the previous layer of lotion.
- Magnesium milk or Pepto-Bismol can also be used to treat rashes. Both products are alkaline and can help reduce itching.
Use Dietary Supplements
Take rutin supplements. Some herbs and dietary supplements possess natural anti-inflammatory properties. Rutin, a flavonoid compound found in citrus fruits and buckwheat, helps reduce inflammation and swelling by preventing leakage from blood vessels.
- The recommended dose of rutin is 250 mg every 12 hours.
Consume quercetin. Quercetin, another flavonoid compound, also reduces inflammation and swelling. It is produced in the body from rutin. To boost your quercetin intake, consume more fruits and vegetables such as apples, citrus fruits, onions, parsley, cherries, grapes, blueberries, and raspberries. You can also drink tea, red wine, or use olive oil to improve quercetin absorption. Quercetin is available in supplement form.
- Quercetin is more effective than cromolyn, a prescription medication that prevents histamine production, thereby reducing rashes.
- If using supplements, consult your doctor for the correct dosage as it may vary based on individual needs.
Use Indian basil. Indian basil, native to Southeast Asia, has been used in ancient Indian medicine. Research indicates that it helps reduce histamine and leukotriene production from mast cells during a rash.
- Typically, a daily dose of 100 to 250 mg of Indian basil is recommended, but there are no strict guidelines. It is advised to consult a doctor for specific dosage recommendations.
Reduce Stress
Relax. While the exact link between stress and hives remains unclear, stress seems to make us more susceptible to outbreaks. It's important to schedule time each day for a relaxing activity such as walking, reading, gardening, or watching a movie. These activities can help alleviate stress.
- Since relaxation is a subjective experience, find what brings you joy and comfort and make it part of your daily routine.
Practice deep breathing techniques. Deep breathing can significantly help reduce stress. Here’s how to do it: Lie flat on your back, placing a pillow under your knees and neck for comfort. Place your palms on your abdomen, just below the ribcage, with fingers interlaced. As you breathe deeply, your fingers should separate, indicating proper form. Inhale deeply, inflating your belly as if you were a child breathing from the diaphragm. Remember to use your diaphragm instead of your ribcage, as the diaphragm creates a stronger suction that pulls air into the lungs.
- Always breathe from the diaphragm, as it generates a stronger pull of air compared to the ribcage.
Say positive affirmations. Positive affirmations are statements you say to yourself to reduce stress and boost your spirits. Use the present tense and repeat them as often as possible. Common affirmations include:
- Yes, I can do this.
- I am successful.
- My health improves every day.
- I feel happier each day.
- Some people write these affirmations on sticky notes and place them around their home to ease daily stress.
Understand Rashes
Recognize the symptoms. The symptoms and external appearance of a rash may only last for a few minutes, but they can also persist for months or even years. Rashes can appear anywhere on the body, but they are most commonly found in areas that come into contact with allergens, manifesting as swelling and itching.
- Rashes are typically round but may merge to form irregularly shaped larger patches.
Diagnosing a Rash. Rashes are typically diagnosed through direct visual inspection. If you're unable to identify the cause of your rash, a doctor will conduct tests to pinpoint the origin. These tests often include allergy tests to evaluate how the skin responds to different substances.
- If these methods are unsuccessful, blood tests and skin biopsies may be required to examine the skin under a microscope.
Taking Medication for a Rash. For mild to moderate cases, antihistamines are usually taken. These can be purchased over the counter or prescribed by a doctor. The medications include:
- Sleep-inducing antihistamines like brompheniramine (Dimetane), chlorpheniramine (Chlor-Trimeton), and diphenhydramine (Benadryl).
- Non-sleep-inducing antihistamines such as cetirizine (Zyrtec, Zyrtec-D), clemastine (Tavist), fexofenadine (Allegra, Allegra D), and loratadine (Claritin, Claritin D, Alavert).
- Corticosteroid sprays that can be purchased over the counter, like Nasacort, and prescription corticosteroids such as prednisone, prednisolone, cortisol, and methylprednisolone.
- Mast cell stabilizers like sodium cromoglycate (Nasalcrom).
- Leukotriene inhibitors such as montelukast (Singulair).
- Topical immunomodulators like Protopic and pimecrolimus (Elidel).
Seeking More Professional Medical Solutions. In rare cases, a rash can cause swelling in the throat, which may lead to an emergency requiring epinephrine. Epinephrine is also used in the form of an EpiPen for those with severe allergies, helping to prevent anaphylactic shock, a serious allergic reaction that may occur with or without a rash. Symptoms of anaphylaxis include:
- Skin rashes, possibly accompanied by itching, redness, or paleness.
- A warm sensation.
- A feeling of a lump in the throat.
- Wheezing or difficulty breathing.
- Swelling of the tongue or throat.
- Rapid pulse and heartbeat.
- Nausea, vomiting, or diarrhea.
- Dizziness or fainting.
Advice
- For precaution, always apply a small amount of topical medication on a limited area to ensure you aren't allergic. If no reaction occurs within 5 to 10 minutes, you can apply it to the entire rash.
- These medications should not be used on children under five years old without medical supervision.
- If the rash becomes chronic or persists for an extended period, it is advisable to consult with a specialist. An allergist will investigate the cause of the allergic reaction through tests that often include evaluations for food, plants, chemicals, insects, and insect bites.
