I love peppermint oil, and it seems that a lot of people share that opinion. Peppermint oil is one of the most commonly used essential oils right now. As an EO fan, I diffuse a lot of it because of its minty smell. Further, some recipes and blends call for this essential oil.

Peppermint oil is not only useful, but it is also affordable. Because of its popularity, peppermint oil is always in high demand. Fortunately, supply has kept up. In 2011, the United States manufactured around seven million pounds of peppermint essential oil. Additionally, the United States produces more than 5.4 million pounds of peppermint in any given year since 2000.

What Is Peppermint Oil?

Peppermint oil is a well-known essential oil used in flavoring your food. You can also use it to add fragrance to different products. It also has potential in treating several health conditions.

It is the extract from the leaves of the perennial flowering herb. Peppermint belongs to the same family as lavender, rosemary, spearmint, sage, and thyme. You can extract this oil by steam distillation if you can obtain fresh or partly dried leaves. You can also use hydrodistillation, which uses water instead of steam.

It can be colorless, or it might have a pale greenish-yellow or pale yellow color. If you put it on your skin, it will feel cold.

How to Select a Good Peppermint oil

If you want to buy this oil, there are a lot of options from different manufacturers and sellers. How do you choose the best peppermint oil products? Here are some tips from the Alliance of International Aromatherapists.

First, you should have an idea of how you are going to use it. If you are buying peppermint essential oil for medicinal use, then be sure to get a therapeutic grade product. For those who are using it for candles, cleaners, and soap, then choosing a medium quality oil will be enough.

If you have access to different brands, then you should do a sniff test. Choose the one with the scent that you like the most. You can also test for quality by checking the smell, which should be minty and sweet at the same time.

Aside from the scent, you should also choose peppermint oils that have a clear, pale greenish yellow, or pale yellow color. It should also not leave any stains when it evaporates. The best peppermint oil will have a thin and dry texture.

If available, check the gas chromatography-mass spectrometry laboratory results for the peppermint oil that you want to buy. It should contain around 20 to 50 percent menthol, up to 31 percent menthone. It should also have small amounts of methyl acetate, pulegone, and isomenthone, among others.

Pure peppermint essential oil will have a .900 to .907 specific gravity at room temperature. It will also have a refractive index of 1.461 to 1.4631. You could see all of these in the GC/MS results.

Choose brands you can trust

Buying from a trusted company can assure you that you are getting quality oils. You should buy from manufacturers that include information on their products, their processes, and how to use it safely. These companies also label their products accurately.

Be sure that you choose a brand that does not use toxic additives such as phthalates, which can be carcinogenic. You should also patronize manufacturers that do not use pesticides, biocides, or fertilizers. It is important to go 100% organic when choosing your peppermint oil.

No cornmint

There are peppermint oil brands that have cornmint oil added in the mixture. Aside from buying a contaminated product, cornmint oil also works differently from peppermint. It might not give you the potential health benefits you want.

Read the label

The most crucial step in choosing the best peppermint oil is to take time to read the label. Premium quality peppermint essential oil should have a label stating the complete botanical name, the country of origin, the batch number, and date.

It should also detail the extraction method and which part of the plant they harvest. The manufacturer should also indicate if it is pure 100% oil and include safety instructions. Lastly, it should come in a sealed colored glass.

Warnings and Side Effects of Using Peppermint Oil

In general, you should not use essential oils when you are pregnant, and you should avoid using it on children without proper guidance.
