How to Get Rid of a Rash: The Best Home Remedies (Research Based)

A rash can appear on any area of the body and because it can be due to many different factors, getting rid of a skin rash involves knowing its cause. Some common causes of rashes are eczema, psoriasis, rosacea, allergic reactions to some substances, bacterial or fungal infections, and taking certain medications. Sometimes, factors like stress, using harsh soaps, changes in temperature or other underlying medical conditions can aggravate a skin rash.

There are many effective ways to get rid of a rash quickly using natural treatments. Some of the best home remedies for a rash include ingredients to soothe the inflammation, relieve the itchiness, and get rid of any germs that irritate the skin. For example, coconut oil, tea tree oil, oatmeal, aloe vera, and chamomile all have antimicrobial and calming properties that are beneficial for healthy skin.

Natural treatments also help to relieve the discomfort and irritation that skin rashes cause. For example, along with the inflammation, you may experience itchy skin, blistering, scaling, and bumps on the skin. There are many effective natural cures to help treat these rash symptoms.

Before looking at the best home remedies to get rid of a rash, let’s look as some of the common causes why rashes on the skin can appear.

Common Causes of a Rash

According to dermatologist Dr. Gary Cole, a rash refers to any kind of skin inflammation or discoloration that changes the normal appearance of the skin.1 Some common causes of a rash can include:

Eczema. Dr. Cole explains that atopic dermatitis (eczema) causes red, weeping rashes on the back of the elbows and knees, on the cheeks, wrists, and ankles.2

Rosacea. Rosacea causes rash-like symptoms on the face that include flushing, sensitive and dry skin, and spider veins.3

Psoriasis. Doctors at the Mayo Clinic say that psoriasis is a chronic inflammatory skin condition. It causes skin cells to form thick, red, itchy patches with scaling.4

Heat. Dr. Benjamin Wedro on says that a heat rash occurs when sweat gets blocked in the skin’s pores. The result is inflamed skin that causes a rash. You may also have bumps on the skin and experience blistering.5 Heat rash is also one of the common causes of rash on inner thigh.and can even appear on the buttocks.

Contact dermatitis. According to the American Academy of Dermatology, contact dermatitis can affect most people. Allergic skin reactions or substances that irritate the skin cause a rash to appear. Depending on the severity, contact dermatitis can also cause dry skin, itching, stinging, and blistering.6

Fungal or bacterial infections. Skin infections caused by yeast or bacteria can cause outbreaks of red skin rashes. For example, bacteria that accumulates in the folds of skin can cause impetigo which causes discolored skin rashes.7 Ringworm is caused by a fungal infection and causes a circular red rash on the skin.8

Drug rash. A skin rash can be a side effect of some medications. Dr. Wingfield Rehumus from the University of British Columbia says that drug rashes cause redness, bumpy skin, tiny red spots (petechiae), hives, and itching. Usually, the rash will disappear when a person stops taking the medication.9

Hives. Another cause of a rash is hives. The itchy, sore red patches of skin are usually as a result of an allergic reaction. However, stress, extreme temperatures, and exercising can all be one of the causes of hives.

Insect bites. Skin rash can develop as a result of an allergic reaction caused by insect bites. For example, bed bug rash can develop as a result of bed bug bites.

There can be many other reasons why you develop a rash on the skin. If a new rash appears or you can’t get rid of it using natural home remedies, you should visit your doctor or dermatologist.

The Journal of Drugs in Dermatology reported that colloidal oatmeal (ground oatmeal) reduces inflammation, repairs skin, stops itching and is a natural moisturizer. It is also well tolerated as a topical skin healing treatment in persons of all ages, including babies. They concluded that oatmeal is a safe and effective treatment for dermatitis.12

Another study showed that oatmeal can help to reduce drug rashes in all of the patients who used it to soothe their skin.13

Use oatmeal to soothe any kind of itchy rash. You can make an oatmeal mask to apply directly to the skin rash, or you can add 2 cups of oatmeal to your bath water to stop body itching.
