Skin rashes of any kind are no fun. Whether it’s something mild like a reaction to laundry detergent, or something more serious like a food allergy or a skin condition like eczema or psoriasis.

Skin rashes can cause a lot of aches and pains and can appear out of the blue.

Many things can cause rashes, making the root incredibly difficult to identify.

If you’re trying to figure out what’s causing your rash, there are some natural remedies you can apply to help with itching and inflammation. In fact, some options can cure the rash if you treat the cause of the rash.

What is rash?

According to the Queensland, Australia government health system , a rash is a temporary rash or outbreak on the skin that usually appears as red patches or redness or dry, scaly skin.

There are many types of rashes, including eczema, hives, and heat rash. Some may be temporary or chronic.

In some cases, rashes can be a sign of a serious illness, such as measles, so it’s important to see a doctor.

Causes of the rash

Our skin is covered in microorganisms that make up the skin microbiome. When these are balanced, so is our skin.

Rashes occur when the skin microbiome is out of balance.

There are many causes that generate a rash, it can be due to an allergy, to the sun, or even a disease. Below we name some of the most common causes.


Heat rash occurs when the sweat glands in the skin are blocked and sweat cannot reach the surface of the skin to evaporate. This causes inflammation, resulting in a rash.

Similarly, common symptoms of heat rash include red bumps on the skin and an itchy sensation.

Also, the rash appears as reddened skin with small blisters and inflammation. It often occurs in skin folds or areas where air cannot circulate or in hot, humid climates.

On the other hand, heat rash usually disappears when the skin cools down.

Should the area become infected, medical treatment is necessary and can be prevented by avoiding heat and humidity or wearing loose clothing to allow air to circulate.

Irritations and allergies

According to the prestigious Mayo Clinic , one of the most common causes of rashes are allergies.

Contact dermatitis is expressed as a red, itchy rash caused by direct contact with a substance that causes an allergic reaction.

In this sense, many substances can cause reactions, they can be soaps, cosmetics and fragrances, or even jewelry, plants and pet hair or dust mites.

So it’s important to identify allergens that can cause allergies or rashes.

Viral diseases

Viral infections are illnesses caused by a virus, and some, especially those that often affect children or babies, can cause rashes.

While they may seem alarming, they are usually nothing to worry about and go away once the infection clears up.


Rashes can also be caused by medications that the body can react to. The type of rash depends on the medication and the body’s response.

There are several medications that have been linked to all kinds of rashes, and the timing of the rash can vary. This may appear right away or a few weeks after you first take the medicine.

Petechiae Rash

According to the Mayo Clinic , petechiae are small round spots on the skin that appear after bleeding.

The color may be reddish, brown, or purple and is due to bleeding. These rashes appear when the capillaries bleed and blood is spilled on the skin.

This condition can be due to various causes, such as prolonged exertion, medications, or medical disorders as a result of fungal, viral, or bacterial infections.


Also known as Henoch-Schönlein purpura , but more often referred to simply as “purpura,” is a rash of purple dots on the skin caused by a disease consisting of a rash, joint pain, gastrointestinal problems, and glomerulonephritis (a kidney disorder ).

hot tub rash

If you spend a long time in contaminated water or water, a rash known as “hot tub rash” can occur.

This rash is caused by the germ Pseudomonas aeruginosa . This germ is found in the environment and usually appears days after taking a bath in a bad bathtub, lake or swimming pool.

blistering rash

Blisters are small pockets of fluid (serum) that form in the upper layers of the skin after it has been damaged and can appear anywhere on the body.

The fluid that collects under damaged skin protects the underlying tissue and allows it to heal.

The blisters can be caused by friction, heat, burns or contact with strong chemicals or even diseases such as chickenpox.

home remedies to get rid of rash

First, be aware that while some chemical-based skin products can help with symptoms, they also contain toxic chemicals that are harmful to the body.

Parabens and petroleum-based agents are two very common ingredients found in most over-the-counter and prescription creams that can lead to endocrine (hormonal) problems and can cause potential damage to internal organs. They usually don’t cure a rash either, but simply treat the itch.

Below are some of the most common ways that you can help heal a rash naturally.

Keep in mind that they may require multiple applications (some may even take months) before the rash clears up; however, they provide useful nutrients for the skin and will not cause toxicity to the body.

Many can also provide immediate relief to the skin when a rash breaks out.
