Ajwain oil or ajowan oil has great health benefits. It can improve breathing, reduce inflammation and so much more.
Properties of Ajwain Oil
You can more find more than one botanical name of ajwain or ajowan. There are quite a few actually. The main ones are: Trachyspermum ammi; Carum copticum and Trachyspermum copticum.
You can also find many names for ajwain too like carom and bishop’s weed. So verify the botanical name especially before buying the oil.
Color & Smell
The oil has a light orange to reddish color and a peppery, thyme-like smell.
What’s in the oil?
The main compounds in ajwain oil are thymol, gamma-terpinene, p-cymene, and beta-pinene. Alpha-pinene, alpha-thujene, beta-myrcene, carvacrol, limonene, and terpinene-4-ol can also be found in it.
Benefits of Ajwain Oil
Ajwain oil has many health benefits. It can neutralize free radicals, reduce inflammation, improve breathing, kill microbes like bacteria and fungi, and repel and kill insects.
Ajwain oil is antioxidant in vitro
Lab studies show ajwain oil has in vitro antioxidant benefits.
This 2014 study used two different methods for measuring the antioxidant effects. And the results showed ajwain had comparable results to Vitamin C and gallic acid. That’s awesome! And it’s all because of thymol.
It may be anti-inflammatory
Another 2014 study tested the oil on white blood cells and measured their release of nitric oxide. Mind you, nitric oxide is a common inflammatory indicator.
Can you guess what the results were? The oil greatly reduced the release of nitric oxide. That means ajowan oil MAY be a strong anti-inflammatory agent.
Again, thymol was the key compound causing this benefit. But other compounds like gamma-terpinene, beta-pinene, and p-cymene also showed valuable anti-inflammatory activity.
It can help you breathe better
Ajowan oil may be a bronchodilator. That means it can relax your bronchi and airway bronchi. This can allow more oxygen to get into your lungs.
Evidence for this benefit comes from a 1998 study which tested the oil on guinea pigs. The oil showed significant relaxant and bronchodilatory effects. But thymol was not the cause. Researchers speculated alpha-pinene was the compound responsible for these benefits.
Nonetheless, you may be able to use ajwain oil to ease your stuffy nose and clear sinus congestion. It may also help with treating your cold, cough, or other respiratory problem.
Ajowan oil is antibacterial
There are lots of studies that prove this benefits of ajowan oil.
For instance, a 2015 study looked at ajowan’s effects on 12 species of bacteria. They included Listeria monocytogenes, Salmonella typhimurium and Escherichia coli. The results found ajowan had moderate to strong effects against the bacteria tested. And the oil was comparable to the antibiotic used as the control. Wow!
Similar results were also found in this 2011 study. It tested ajowan oil on fifteen common bacteria. And the oil was able to inhibit and kill all fifteen species.
It is also no surprise that thymol is ajowan’s main antibacterial compound. But alpha-pinene and beta-pinene also add to these effects.
It is also antifungal
There are several studies proving ajowan essential oil is toxic to a wide range of fungi.
For instance, this 2016 study tested the antifungal effects of 15 essential oils on 3 fungi. The oils here included thyme, clove, rosemary, eucalyptus, lemon, oregano and more. The results showed all the oils had strong antifungal benefits.
Again, thymol and beta-pinene are the main antifungal components in the oil.
Ajowan kills insects
There is tremendous evidence exploring this ajowan oil benefit.
A 2017 study explored the effects of 12 oils on German cockroaches (Blattella germanica). Of all the essential oils tested, ajowan and dill were the most potent repellents! The study went on to show carvacrol and thymol were the main repellent compounds.
Another study from 2012 showed ajowan oil can kill the larvae of Aedes aegypti mosquitoes. And this can happen at incredibly low concentrations of the oil.
The study also found the oil in larvae-infested water two days after it was added. So ajowan was persistent enough to prevent the mosquito eggs from hatching.
That means ajowan oil is great for controlling the mosquito population.
One study published in 2009 checked the insecticidal effects of 26 essential oils on Japanese termites. Ajowan, allspice, caraway, dill, and geranium oils had the strongest activity. The oils killed all the termites in under two days.
So use ajowan oil to handle all your insect problems! It has your back for sure.
Oh I should mention, the compound responsible for these effects is … thymol!
Here’s a quick summary of all the ajowan essential oil benefits we’ve seen:
