Several home remedies can help with the treatment of rashes. But before you learn about these home remedies, you must learn about the various kinds of rashes and their symptoms.

What is a rash?

The term rash does not have any precise definition but refers to a wide variety of skin eruptions.

A rash is an inflammatory condition of the skin that changes the color, appearance, or texture of the skin.

Different types of rashes have various symptoms. Here’s a list of some  common non-infectious rashes –

1. Atopic dermatitis

Commonly known as eczema, this type of rash produces red, itchy skin on the inner parts of elbows, back of knees, cheeks, neck, wrists, and ankles.

Eczema is common in people with asthma or hay fever.

2. Seborrheic dermatitis

Seborrheic dermatitis is a common rash that causes a red itchy eruption that can affect the scalp, forehead, brows, cheeks, and outer part of the ears.

In infants, it can affect the diaper area and lead to cradle cap.

3. Contact dermatitis

This type of rash occurs when you come in contact with a substance or chemical that irritates the skin.

Contact dermatitis causes weepy and oozy skin, and it affects the part of the skin that may have come in contact with the rash-causing substance.

Poison ivy, poison oak and even costume jewelry that contain nickel can cause this rash.

4. Diaper rash

Diaper rash is a type of contact dermatitis that occurs in infants or adults that wear diapers. It happens when feces or urine are in contact with the skin for an extended period.

5. Stasis dermatitis

This rash occurs on the lower legs of people who have chronic swelling caused by poor circulation in veins.

This kind of rash does not ooze; it produces silvery flakes of skin that scale and fall off. It usually occurs on scalp, elbows, and knees.

7. Hives

This rash causes red and itchy bumps. Hives can occur suddenly and usually go away in eight hours.

Most rashes are not dangerous and usually go away on their own after a few days. People generally use over-the-counter remedies to treat rashes. These include –

  • Moisturizing lotions
  • Anti-itch creams containing 1% hydrocortisone cream
