Treatment of miliaria or prickly heat rash includes natural applications that soothe and calm the rash. Naturally, apple cider vinegar is an effective treatment for detoxifying the affected pores. Additionally, organic powders help soak up excess sweat and prevent the condition.

What Is Miliaria?

Also known as heat rash, prickly heat affects individuals of all ages, particularly during hot, humid weather. Characterized by red to white bumps on the skin and an itchy or prickly feeling in the affected area, miliaria can be extremely uncomfortable.

Miliaria develops as the sweat ducts in a particular area become clogged. When this clogging occurs, the sweat does not evaporate as it should but rather remains beneath the skin, causing the characteristic inflammation and rash. Contributing factors may include immature sweat ducts, a tropical climate, physical activity, certain fabrics and medications.

Home Remedies for Prickly Heat Rash

Home treatments for prickly heat include a variety of options to eliminate clogged pores and the associated irritation. Treatment options include apple cider vinegar, castor oil, aloe vera and others. Additionally, keeping the affected area clean and dry helps eliminate the condition.

Apple Cider Vinegar

Apple cider vinegar treats the underlying cause of miliaria. As he condition is caused by clogged pores, applying apple cider vinegar to the affected area removes dirt and toxins naturally and safely. The vinegar also serves as an anti-inflammatory agent when used in a diluted form.

Castor Oil

Derived from the bean of the castor plant, castor oil is rich in ricinoleic acid. This acid penetrates the skin, nourishing and moisturizing it. The oil is also antimicrobial, so it eliminates infection, serves as an anti-itch agent and delivers pain-relieving properties.

Aloe Vera

Aloe vera is a natural cooling agent. When applied to prickly heat, aloe vera relieves itching and cools the affected skin. Aloe vera also helps heal the rash.

Miliaria is an uncomfortable skin condition marked by a red, rough inflamed skin rash. If treated with natural methods such as apple cider vinegar and aloe vera, however, the rash can be not only soothed but also eliminated.

So I started getting miliaria (heat rash) when I was about 17 and it was horrible! I was cooped into the house for so long... I took calonine to get rid of it some but no one would be able to figure out what it was so I had to find it on my own and when I found it it made all sense!

So I still delt with it for awhile and I thought of apple cider vinegar being a cure all so I decided to take a bath with it and soak in it for about 20 mins in warm water (sounds bad but it worked) and I did that for about a few week and then up until now because I quit taking a bath with it and it came back. But when it starts coming back I go and take a bath with the apple cider vinegar and I'm back to normal again!

Try it! It works!

ACV for Miliaria (Prickly Heat)

This is completely embarrassing. I'm a woman with large breasts and, unfortunately, I gained weight that I'm now working off.

One day I was in the shower and noticed that the skin under my breast was very itchy. I looked and noticed it was a rash. I'd never had anything like it and, a few days later, realized it was prickly heat because of my heavy breasts. I then looked at pics of prickly heat cases and pretty much my skin looked just like it. :(

I read that apple cider vinegar might help. (It helps with so many ailments that I figured why not try it?) However, I knew my skin was tender, so I watered it down with about 50% water. I got a cotton ball and applied it to the skin under my breasts. There was a little stinging but the itching went away. I treated my skin consistently for a day. Then I went to the gym. I brought some cotton balls soaked in 100% ACV with me and used them after I showered. I've decided that I'll probably be a risk for this until I loose the weight that I need to loose.

Now I apply a little ACV after my showers. I even put a little ACV under my breasts before working out. That might be a bit excessive, but I want to avoid this from happening again. It's just not a good feeling. Also, before getting dressed, I follow up with baby powder to soak up any sweat.

Embarrassing to have prickly heat there, but I have it and ACV has saved me again.

I tried most all of the Internet remedies for heat rash and thought I'd go insane with the itching. I have been plagued with this for 3 summers which makes living in South Texas no picnic or day at the beach! I have found much relief from making a 50/50 apple cider vinegar and water mix. I put it in a spray bottle and use it as an "after bath splash". I also diligently scrub the area and dry thoroughly but I think the Apple Cider Vinegar is the key. I suspect it is fungal in origin and that the Apple Cider Vinegar has remedied this. Blessed relief!


Thanks for the info on Apple Cider Vinegar and prickly heat in Texas. My neighbor is really suffering. He will give it a try.

Our child had a heat rash and castor oil worked best. We tried the ACV on one side and castor oil on the other.. Both my wife and I agreed that castor oil worked best and quickest.

I am just wondering, how would you spread the castor oil on several parts of the body? The rash my son has is in various places on his there a way to thin it out for spreading purposes?

Thank you so much.
