How Essential Oils Can Improve Health Symptoms
Essential oils have been used all over the world for hundreds of years to bring relief from everyday health issues, including headaches, nausea, and anxiety.
Primary application methods are either topical using a diluted oil on pressure points or directly applying it to the affected area of skin.
Other popular treatments include air diffusion and steam treatments, where the healing essence is breathed in to provide further relief.
These natural oils are antibacterial and, when used properly, can do things like reduce fevers and eliminate aches and pains.
What is Motion Sickness?
Many people are susceptible to motion sickness due to genetics or pre-existing medical conditions.
The nausea and vomiting that can accompany it are caused by the brain getting mixed signals from the body.
Primarily this happens while riding in vehicles or whenever information relayed to the brain from the inner ear does not match up with what the eyes are observing.
For example, sitting in a moving vehicle can lead to the eyes seeing movement that the body is not feeling, which results in sickness.
How to Apply the Essential Oils for Nausea
Motion sickness can happen anytime, anywhere, but it usually strikes when you are on the move in a car, boat, or aeroplane.
Due to the limited space when travelling, it is good to know that topical application is incredibly useful for treating nausea.
There are also several other options for anyone who finds themselves at home suffering from motion sickness due to illness, injury, or prolonged reaction to a trip.
There are several models of air diffusers, but they all work in the same fundamental way.
They have a tank for placing the oil and a medium such as water. One common type is the sonic diffuser, which has a ceramic plate that vibrates at a high frequency when it is plugged in.
This motion breaks down the oil, mixes it well with the water, and disperses it into the air in the form of a light mist. This is then breathed in, and the oils do their work healing the body.
The most common way to do an aromatherapy steam treatment is to boil water, place it in a heatproof bowl or container, and add a few drops of your preferred oil.
You can lean over it with a towel over your head to soak up any humidity and let the steam fill your lungs.
Although breathing through your nose can get you some great benefits, you do not want to do that for longer than a few minutes at a time, or it might lead to bouts of dizziness.
Long, deep, open breaths will allow the oil to do its work.
When doing steam aromatherapy, one thing to remember is to limit the amount of time you spend breathing it in. Too much is not healthy for your body’s system. Twenty to thirty minutes is a reasonable limit to how long you should spend per steam session.
A bottle with a wick in it can serve as an aromatherapy inhaler. You can buy them off sites with essential oil products.
A well-mixed combination of essential oil and water is put into the bottle, and then during trips or when you are feeling motion sickness, you can remove the cap and inhale the oil.
Applied Directly On Skin
When applying essential oils directly onto the skin, you will need to check what rate of dilution is recommended by the distributor.
Oils are concentrated, which means that you may get sick if you absorb too much into your skin.
The safest way to use essential oils in topical treatments is to dissolve them into creams or other oils, which are skin-safe, such as coconut oil.
The exact ratio will depend on which one you are using, but the rule of thumb is to limit the essential oil to approximately 3% of the combination.
Two or three drops for every half-ounce of the mixture will usually do the trick.
If you notice any discolouration, itching, or discomfort at the site, then discontinue your use of the oil immediately.
Allergies are not uncommon with natural ingredients like those used in essential oils.

In essential oils, lemon oil is one of the go-to for stomach upsets.
It is known to help decrease symptoms such as dizziness, nausea, nervousness, and stomach cramps.

It can also be mixed with one of the oils mentioned above. Many recipes for motion sickness oils involve mixtures of three or more to increase potency.

A 2012 review of studies involving essential oils used to treat nausea showed that there is reason to believe peppermint oil and ginger oil can treat it. (Source: https://pubmed.ncbi.nlm.nih.gov/22784340/)
Other studies have shown mixed or lower-end results that put essential oil use on par with the placebo effect, which means there is still more research to be done on the topic. (Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6494172/)
