Natural Remedies for Diaper Rash: What the Evidence Says

A laughing toddler in a bath, the plain water that cleans a sore diaper area best

The most effective natural treatments for diaper rash are the dull ones: air, plain water and a barrier of zinc oxide or petroleum jelly, which are about as natural as a pharmacy gets. Beyond those, a few kitchen remedies have small trials behind them, several have none, and three can make the skin worse.

Below is each remedy parents ask about, with the size of the study behind it where one exists. Most diaper rash trials are small, short and run in a single hospital, so read every positive result below as a reason to keep a remedy on the list and no more than that.

Home remedies for diaper rash, by strength of evidence
Remedy	What the evidence shows	Our view
Air time, plain water	Recommended by the AAP, NHS and every paediatric source we checked	Use first, every time
Zinc oxide or petroleum jelly	Standard barrier care in AAP and NHS guidance	Use at every change while it heals
Your own breast milk	Review of 5 studies, 238 infants: some benefit, low certainty	Reasonable alongside a barrier cream
Calendula ointment	One trial, 66 infants: fewer rash sites than aloe	Promising, thinly tested
Aloe vera	Improved rash in the same trial, less than calendula	Pure gel only; sunburn gels can irritate
Coconut oil	No diaper rash trial found	Safe as a moisturiser, unproven here
Olive oil	Indian Academy of Pediatrics: harms the skin barrier	Skip
Baking soda paste	No trial; may dry the skin and little else	Skip
Apple cider vinegar	Acidic; can irritate	Skip
Essential oils	Poison Control: can cause rashes, some are poisonous through the skin or swallowed	Never on a baby

Breast milk

This has the most research of any home remedy, and it's still thin. A systematic review published in 2026 found five studies covering 238 infants between 2015 and 2025. Two looked at prevention and suggested fewer or milder rashes. Three looked at treatment and reported faster healing with breast milk alone or combined with zinc oxide. The reviewers rated the certainty low to very low, because the trials were small and measured different things in different ways, and concluded that breast milk is a reasonable low-cost addition to standard care but not a replacement for it. In practice that means a few drops on clean skin, left to dry fully, with the barrier cream on top. A rash that hasn't improved in two or three days needs a doctor whatever was applied.

Calendula and aloe vera

The one direct comparison is a 2012 double-blind trial in Iran of 66 children under three. Half received aloe cream and half calendula ointment, three times a day for ten days. Both groups improved, and the calendula group finished with significantly fewer rash sites, with no side effects reported in either. There wasn't a zinc oxide group or an untreated one, so the trial tells you calendula beat aloe and doesn't tell you whether either beat the cream you already own.

On aloe, a Cleveland Clinic paediatrician adds a practical caution: it soothes only in its pure form, ideally straight from the plant, because the aloe gels sold for sunburn carry other ingredients that can irritate broken skin. Read the label for fragrance and alcohol before either one goes near a diaper area, since that's where most of the trouble starts.

Coconut oil and olive oil

We found no trial of coconut oil on diaper rash. The Indian Academy of Pediatrics' skin care guidelines prefer coconut, sunflower or mineral oil for baby massage, and in the same passage advise against olive oil and mustard oil, which it says damage the skin barrier. Coconut oil is therefore a sensible moisturiser on intact skin. As a treatment for an active rash it's unproven, and it isn't a barrier in the way zinc oxide is.

A small 2005 study tried a mixture of honey, olive oil and beeswax on twelve infants and reported improvement over a week, but with twelve babies and no comparison group I wouldn't specify it.

The rest of the routine

Three to leave in the kitchen

Baking soda paste circulates widely online. The Cleveland Clinic's paediatrician says it may help keep the skin dry but won't do much else, and air does that job without leaving a residue. Apple cider vinegar and similar acidic remedies can irritate skin that is already sore, which is the opposite of what a rash needs.

Essential oils are the one category to keep away from babies entirely. America's Poison Control centre says many of them cause rashes on the skin, some are poisonous when absorbed through the skin or swallowed, and none should go on damaged skin, which describes every diaper rash. It adds that children's thin skin and immature livers may make them more susceptible than adults, and that an oil a child chokes on can reach the lungs and cause pneumonia. A diaper area is somewhere small hands go.

What we would do first

Change more often. Clean with water and a soft cloth instead of wipes while the skin is broken, pat dry, give it time with no diaper on, and put zinc oxide or petroleum jelly on dry skin at every change. If you'd like to try breast milk, it goes under the cream. Our diaper rash guide covers the routine in full, including how to tell an ordinary rash from yeast, which no kitchen remedy treats.
