6 Top Benefits & Side Effects Of Ajwain Water (Omam Water)

ajwain water benefits
Ajwain water is a popular home remedy for treating gastritis and indigestion in Tamil Nadu and it is also consumed for aiding weight loss. I always stock ajwain seeds at home and use it in home remedies extensively. We get ready made ajwain water in the markets but it is loaded with sugar, so it is best to make it at home yourself and it is so easy to do.

What Is Ajwain Water?

Ajwain seeds (Hindi name) commonly called “Omum” in Tamil, “Bishop’s weed” in English are small grayish colored seeds with a very strong distinctive smell. The decoction of the seeds got by boiling the seeds in water has wonderful health benefits both for adults and children. We call it omum water | omam | oma water in Tamil and ajwain water in Hindi.

Ajwain water medicinal usesAjwain Water Health Benefits:

1. Ajwain Water For Cold & Cough: 

Ajwain water is great for consuming while suffering from cold or cough as it helps reduce cough, this is due to it’s antitussive and bronchodilating properties. If you are suffering from any respiratory problems like cold, cough, headache or asthma, try a cup of warm ajwain water, it will greatly help.

2. Ajwain Water For Stomachache:

When I was younger, whenever I came home from hostel, I used to overeat often and get stomachache. To cure it, my mom always used to give me ajwain water and usually I will be alright very soon. Ajwain water is a very good home remedy for people suffering from stomach related problems which includes indigestion, stomach pain and gastritis.

3. Ajwain Water For Babies: 

Ajwain water can be safely given to very small babies too. Oma water is so very famous here in Tamil Nadu as a medicine for treating indigestion in children, it is also given to babies who don’t have a good appetite. I think every home with children should have a bottle of ajwain seeds, ready to make ajwain water any time.

4. As An Insecticide:

Ajwain seeds have insecticidal properties and is effective in getting rid of cockroaches and mosquitoes if used as a spray. To make the spray, take ajwain water in a spray bottle, add in 10 drops of rosemary or peppermint or citronella essential oil and mix well. Spray this in all nooks and corners to get rid of insects for good.

5. Ajwain Water For Weight Loss:

Ajwain water is now popularly consumed as a weight loss drink. I couldn’t find any studies supporting the claim but thymol extracted from ajwain seeds has been proven to help prevent weight gain, you can read the study that supports this claim here. Please remember that herbs only helps speed up the process. For any meaningful weight loss, a healthy calorie deficit diet and regular exercise is important.

6. Other Health Benefits:

It helps with all metabolic diseases which includes high blood pressure, cholesterol and blood sugar levels. If you are suffering from any of the above mentioned diseases, try including ajwain water in your diet regularly in moderation. It also helps reduce inflammation very effectively so people suffering from inflammatory conditions like arthritis will highly benefit including it regularly.

Out of 75 pregnant woman who were tested, 50 experienced abortion and fetotoxicity!

So it is best to avoid ajwain water when planning for pregnancy and also during pregnancy.

Excessive consumption of ajwain water can lead to bloating and stomach irritation. Some people can be allergic to ajwain seeds, ajwain allergy can cause nausea, dizziness and vomiting. It also interacts with certain drugs, if you are on any medication and planning to consume ajwain water regularly please mention it to your physician without fail.

      All these three ingredients are very good for inflammation and will generally help with any bowel disease. Sukku coffee can be had for both crohn's disease and ulcerative colitis….

      Since I use it as a remedy, I always have it immediately after making this oma water | ajwain water. I would suggest tasting a tiny little bit to know whether it is spoilt, usually it does not spoil fast……

    I bought 150 ml of OMUM WATER from the retail shop as i have stomach ache. Can i drink the whole omum water (150 ml) in a single dosage?

      I don't use store bought oma water so I don't know the correct dosage. But please don't consume 150 ml of oma water in a single dosage, I would suggest taking 1.5 tbsp to 2 tbsp of the oma water and if the stomach pain does not subside you can take the second dosage again….

    Hi, today I gave about 100 ml of Ajwain water for my 9 month old baby. I made her drink the whole day. Infact I wanted to drink the water as I have sevior cough so I used about a tea spoon of Ajwain in about a litre of water boiled. So I thought of giving the same to my baby as well as I felt this is good for digestion. I read ur post only now when I was looking for something. Kindly let me know if the amount of water given was ok?

      Hi, Renuka, I would suggest using omum water | ajwain water only as a remedy when she suffers from indigestion and definitely not often. I would suggest using 1/4 tsp of ajwain seeds boiled in water and given as a single dosage…

    do you mean teaspoon or tablespoon? i talked to two people who said omam is very strong and one woman said she only uses a pinch or 1/4 a teaspoon for 1 cup of water. but you are suggesting 1 to 2 tablespoons for 1 cup of water which is a lot.please clarify. i took a few seeds and chewed on it and indeed it is very very strong.tastes like murukku. 🙂

      I am so very sorry for the late reply. We use 1 tbsp of omum seeds for 250 ml of water, so the amount of omum seeds is correct for that amount of water. We usually take only 2 to 3 tbsp of the boiled mixture(omum water) and then take the remaining in the evening. I should have explained it clearly, sorry for confusing you. For children if it is too spicy, you can reduce the amount of omum seeds to 2 teaspoons…

    If we add one cup of water to the pan and let it boil, do we have to allow it to reduce to a quarter cup? The water that you have strained looks so less. If adults consume only 2 – 3 tbsps at a time, is the rest discarded? I am asking because you said you prefer to make it fresh every time. How many times should this be consumed and for how many days for gastritis? Please advise.

      Sorry, I should have been clear. For adults, 1/2 cup water boiled with 1 tbsp ajwain seeds and reduced to 1/4 cup as a single dosage once a day. For children 1.5 tsp of ajwain boiled in 1/4 cup till ti reduces to almost half as a single dosage. Usually when I have gastritis, having it once itself I will be alright. But you can have it twice a day, if it does not get alright in a single dosage….
