How To Dilute Peppermint Oil

There are two things to remember when you want to know how to dilute peppermint oil. The first is someone’s age, and the second is the time of day.

Peppermint is chock full of constituents to help you concentrate or to settle your digestion, but because they are so refreshing, peppermint will keep you awake all night.

Sleep is out of the window! But, then, menthol is a potent constituent that slows respiration, so we would use it with much more care in children than in adults.

This article looks at how to safely and efficiently dilute peppermint oil. We’ll investigate the different conditions it can be helpful for, discuss anyone who should not use it (pregnant women, for example), and identify any likely problems that arise with peppermint oil.

How To Dilute Peppermint Oil - Maximum Dilutions

Do not apply this oil neat. Essential oils should always be diluted into carrier oils and spread over a large surface skin area. We have several of them for you to choose from on our site.

We recommend 3% dilution for adults, 2% for people in a weakened state, and 0.25% for children over 6. We do not recommend using essential oils on children under 6 months old unless it is an emergency.

How to Dilute Essential Oils

Dilution is so much easier in metrics than it is in imperial measurements!

A great guide is that a teaspoon holds approximately 5ml of oil which equals about 100 drops of carrier oil. 

If you work with teaspoon measures, dilution becomes simple. 

    • 3% dilution of peppermint oil in a teaspoon of carrier oil is 3 drops 
    • 2% dilution for someone who is weakened (Has been ill, if frail and elderly)
    • 1 drop = 1% dilution.

Easy peasy lemon squeezy!

Incidentally, if you come into contact with spillage and are exposed to more significant concentrations than noted above, just add more vegetable oil to dilute it, then wash it off with soap.

Calculating g dilution for children is harder because how do you do a quarter of a drop? 

Do four teaspoons, roughly a tablespoon of the carrier, and splash more if you're lazy. Then one drop of peppermint oil in that. Peppermint is never a good choice for children…

Peppermint Essential Oil Energetics

This is a very refreshing oil. It is fabulous if you feel sluggish, lethargic, or need to focus, but kids are naturally already that way. Giving peppermint essential oil is like shoveling a ton of sugar in their faces and then washing it down with amphetamines…it’s just a terrible plan. Not only will they bounce off the ceiling, but they’ll also be awake for hours.

The high levels of menthol in Peppermint essential oil t can make it a tough choice for children. As an essential oil, it fibrillates the heart. It makes it beat much faster, making us feel more alert and switched in. However, the menthol in it also slows respiration, so it would never be a good plan to apply it close to a child's face. If you really must use it, only apply it to their back. However, in our opinion, regardless of why you want to use peppermint essential oil, there will always be a better alternative if it comes to kids.

How To Dilute Peppermint Oil Safely: What To Look Out For

Pregnancy and Breastfeeding

We do not recommend using peppermint essential oil during pregnancy. While Peppermint essential oil is theoretically deemed safe for breastfeeding, essential oils do pass through into breast milk that not all babies like. If your child suddenly becomes reluctant to feed, cease use for a couple of days to ensure it is not the oil affecting their palate. Moreover, it is not conducive to either mom or baby getting a good night’s sleep. Therefore, we do not recommend using peppermint oil when breastfeeding.


We recommend that the maximum time you would diffuse for any purposes would be 2 hours before taking half an hour’s break. This applies to humans and creatures alike!

Dealing with Accidents

Keep essential oils out of the reach of children. We do not advise ingesting any essential oils. However, if it does happen accidentally, drink milk and seek medical assistance. Take this leaflet and the oil bottle with you to the emergency room. Avoid inner ears, eyes, and sensitive areas. If you should get it into your eyes or start a skin reaction, we suggest rinsing with vegetable oil to dilute it more. Do not try to rinse with water; oils and water do not mix, so it will merely spread the oil over a larger surface area. Cold full-fat milk will work, but it must have a high-fat content to absorb the essential oil. If you do happen to develop a rash, discontinue use immediately.

Other Safety Concerns

It is not recommended that Peppermint essential oil is used by anyone with either cardiac fibrillation or who has a deficiency of the enzyme G6PD. G6PD deficiency is a well-recognized deficiency that affects the blood. It is mainly found in men.

Peppermint Oil for GERD

However, if you suffer from gastroesophageal reflux, peppermint can further loosen the valve that contains acid in your stomach, allowing digestive juices to come up into the chest. Chamomiles, aniseed, fennel, or ginger will do a better job.

How to Dilute Peppermint Essential Oil Around Pets

It’s best to try to use your peppermint essential oil away from your animals if you can.

Peppermint essential oil can be used safely around dogs, but they often don’t like the smell. Likewise, it is repellent to most rodents and spiders.

It poses a potential risk of toxicity to cats as they do not possess the correct enzyme to metabolize some of its components in their livers. This means the oil does not break down into smaller parts in their system, so it’s as if they have imbibed it undiluted. In addition, diffusers, evaporators, and even reed diffusers propel drops into the air, which could land on your cat. Limit the time you leave it in the room, as the longer it stays, the more chance it has of collecting droplets on its fur and then grooming itself, which could be hazardous.

Please note that both cats and dogs have profoundly more vital senses of smell than we do, and like humans, each has its likes and dislikes, so always make sure the door is open for your pet to leave the room when they have had enough.

A Note on Cat Toxicity

Introducing something new to the home is worth watching how it affects everyone. Some cats can develop a runny nose or itchy eyes from strong fragrances or burning sensations in their nose and throat. Watch out for them drinking more water than usual. Drooling can be a sign they feel nauseous, and watch for them vomiting or having difficulty breathing. They might seem to be coughing up a hairball, indicating respiratory irritation. If any of these start, the first thing to do is to get them out into the fresh air. Usually, being moved away from the scent will help. If not, then seek urgent veterinary assistance. Remember that you are witnessing poisoning, and they need immediate assessment.
