Botanical name

There are a few botanical names for ajwain. You’ll see Trachyspermum ammi; Carum copticum and Trachyspermum copticum.

The oil has a light orange to reddish color and a peppery, thyme-like smell.

What is in the oil?

The main compounds in the oil are thymol, gamma-terpinene, p-cymene, and beta-pinene. Alpha-pinene, alpha-thujene, beta-myrcene, carvacrol, limonene, and terpinene-4-ol have also been reported.

This 2014 study looked at two methods for measuring antioxidant activity. And the results were interesting. It showed ajwain oil had really good antioxidant effects; comparable to the likes of Vitamin C.

That’s awesome! And it’s all because of thymol.

It may be anti-inflammatory

Another 2014 study found the oil can reduce inflammation. And again, it’s all because of thymol. But compounds like gamma-terpinene, beta-pinene, and p-cymene have also exhibited very good anti-inflammatory benefits.

It can help you breathe better

Do you know what a bronchodilator is? It’s something that can help your airways to relax. And when they relax, more oxygen can get into your lungs and into your blood. Of course, you want that, especially when you have the flu!

And this 1998 animal study on guinea pigs found ajwain oil had relaxing and bronchodilatory benefits. So you can use ajwain oil to ease your stuffy nose and congested sinuses. It also works well to treat coughs and colds.

Oh, and for the record, thymol isn’t responsible for these ajwain oil benefits. It’s alpha-pinene!

Ajowan oil is antibacterial

Take a look at this 2015 study. It tested ajwain oil on twelve species of bacteria including E. coli. The oil showed good antibacterial activity. In fact, its results were similar to the antibiotic used as the control.


These benefits are the result of … you guessed it … thymol! But alpha-pinene and beta-pinene also add to these effects.

It is also antifungal

The oil is toxic to a wide range of fungi. At least, that is according to this 2016 study. It tested 15 essential oils including ajwain, thyme, clove, rosemary, eucalyptus, lemon, oregano and more. And the results showed all the oils had strong antifungal benefits.

Ajowan kills insects

There are loads of studies that explore these ajwain oil benefits.

This 2017 study tested 12 oils on german cockroaches and found ajwain and dill oils were the best repellents.

Another study from 2012 found the oil killed mosquito larvae at really low concentrations. And, not only that, the oil prevented the mosquito eggs from hatching a couple days after the oil was applied.

A 2009 Korean study used 26 essential oils on Japanese termites. And ajwain, allspice, caraway, dill, and geranium oils had the strongest insecticidal activity.

Awesome! Oh, the oils killed all the termites within two days. So got insect problems? Then add some ajwain oil! It repels and kills!

Here’s a quick summary of all the ajowan essential oil benefits we’ve seen:

Ajwain Oil Uses

You can use ajwain oil in so many ways.

Add a few drops to your diffuser to clear up your sinuses, and ease your coughs. Or blend it with spicy oils like sage and thyme. It also works really well with citrus oils like bergamot, lemon and orange.

You can use it in your massaging blends too, but make sure you do a skin patch test to see if you are allergic to the oil. If you are not, then mix two or three drops of ajwain oil to a teaspoon of your favorite carrier oil.

Some aromatherapists suggest the oil may stimulate your appetite. Keep that in mind and talk to your doctor before using the oil. This is important if you are pregnant, breastfeeding or taking any special medication.
