Ajwain Water Benefits: For Periods, Bloating & Pregnancy (Honest Guide)

Ajwain water benefits are a big talk in Indian homes. Your mother or dadi may have handed you a warm cup for gas, or for period pain.

But what does the research really say? This guide gives you the honest answer. It covers periods, bloating, pregnancy and babies, with the sources for each point.

The Short Answer

Quick answer: Ajwain water is a mild home remedy for gas, bloating and period cramps. Small trials hint that ajwain may help, but they used capsules or mixed remedies, not plain ajwain water. It does not bring on a late period. In pregnancy, keep to a pinch in food and ask your doctor.

What Is Ajwain Water?

Quick answer: Ajwain water is carom seeds soaked or boiled in water, then strained. The seeds carry a strong oil, and its main part is thymol.

Ajwain is the tiny, ridged seed of a plant called Trachyspermum ammi. In English it is called carom seed. In Marathi it is ova, and in Tamil it is omam.

A 2012 review in Pharmacognosy Reviews says the seeds hold 2–4.4% oil, known as ajwain oil. Thymol makes up 35% to 60% of that oil (Bairwa et al.).

Thymol gives ajwain its sharp, thyme-like smell (WebMD). When you soak or boil the seeds, some of this flavour moves into the water.

Ajwain Water for Periods: What the Research Says

Quick answer: One small trial found that ajwain capsules eased period pain about as well as a common painkiller. But it used capsules, not ajwain water, and only 70 women. So a warm cup may help a little, but do not expect a cure.

Here is the main study. A team in Tehran tested ajwain on college students with painful periods. The trial ran in 2018 and 2019, and the paper came out in 2023 (Zali et al., Traditional and Integrative Medicine).

• Who: 70 young women with period pain.
• What: half took a 500 mg ajwain capsule three times a day. The other half took mefenamic acid, a common period-pain tablet.
• When: from day 26 of their cycle to day 3 of their period, for three cycles.
• Result: pain went down in both groups. Average pain scores fell a little more in the ajwain group.

The authors wrote: "The findings of this study suggest that ajwain may be effective in pain relief in PD without adverse effects." PD means primary dysmenorrhea, or normal period pain.

Good to know: This trial was small, and the women knew which treatment they got. It also gave ajwain in capsules, swallowed like a pill. A cup of ajwain water is a different thing, and no trial has tested it. So treat it as a comfort drink, not a medicine.

What helps period pain for sure? The NHS suggests a few simple steps (NHS):

• Use a heat pad or hot water bottle on your tummy.
• Try gentle exercise like yoga, walking or cycling.
• Use painkillers like paracetamol or ibuprofen.
• Have a warm bath, or massage your tummy and back.

A warm cup of ajwain water fits well with the heat and rest routine. The NHS says to see a doctor if your pain stops you from doing your usual daily activities.

When to Drink Ajwain Water for Periods

Quick answer: Sip a warm cup when cramps start, or at night before bed. There is no proven best time. Keep it to one or two mild cups a day.

No study has tested the best time to drink ajwain water in periods. So go by comfort.

• When cramps begin: warm drinks can feel soothing on a sore tummy.
• At night: a warm cup before bed is a calm habit for many women.
• With a hot water bag: pair the drink with heat on your tummy, as the NHS suggests.

Can I drink ajwain water during periods? Yes. For most women, a mild cup is fine. If it gives you heartburn, make it weaker or skip it.

Period me ajwain khane ke fayde kya hain? Khane mein ajwain lena theek hai. Par periods mein ajwain chabane ka koi alag fayda kisi study mein test nahi hua hai. Upar wala trial capsule par tha. (In English: eating ajwain in food is fine. But no study has tested chewing ajwain seeds for period pain. The one trial used capsules.)

Can Ajwain Water Bring On a Late Period?

Quick answer: No. There is no proof that ajwain water starts a late period. If your period is late, take a pregnancy test first.

Many reels say ajwain, jaggery and methi water will "bring periods in one day". A 2025 fact check by Health Dialogues looked at this claim. It said: "The claim is FALSE. There is no scientific evidence or medical consensus that these ingredients can reliably or immediately induce periods within 24 hours" (Health Dialogues).

The NHS lists pregnancy first among the common causes of a late or missed period. Stress, sudden weight loss, PCOS (which the NHS now calls PMOS) and some birth control pills are other causes (NHS).

• Take a pregnancy test first. Ajwain is best avoided in pregnancy, so do not use it to try to bring on a period.
• See a doctor if you miss three periods in a row, or your periods turn irregular, says the NHS.

Kya ajwain ka pani pine se period aata hai? Nahi, iska koi saboot nahi hai. Period late ho to pehle pregnancy test karein. (In English: there is no proof that ajwain water brings on a period. If your period is late, take a pregnancy test first.)

Does ajwain water delay periods? We found no study that shows this either. Food and drinks are not on the NHS list of common causes of a late period.

Ajwain Water for Bloating and Gas

Quick answer: Ajwain is a long-trusted home remedy for gas and bloating. One trial of an ajwain and celery seed remedy found it eased bloating and other stomach symptoms.

The 2012 review describes ajwain as a carminative. That means it is used to ease gas. It calls ajwain "an important remedial agent for flatulence, atonic dyspepsia and diarrhea" (Bairwa et al.).

There is one human trial too. In 2017, doctors in Iran tested a remedy made of ajwain and celery seed. It had 150 patients with indigestion, or functional dyspepsia (Azimi et al., Avicenna Journal of Phytomedicine).

The remedy worked better than both a dummy pill and omeprazole, an acid tablet. It eased fullness, bloating, burping and nausea. But it was a mix of two seeds, not plain ajwain water.

For other kitchen drinks that may settle the stomach, see our guides to jeera water, mint water and teas for digestion.

How to Make Ajwain Water

Quick answer: Boil or steep 1 teaspoon of ajwain in 2 cups of water, then strain. Keep it mild. A stronger brew is not better.

FirstCry suggests not more than 1 teaspoon of ajwain in 2 cups of water (FirstCry Parenting). That is a good, mild amount for most adults.

Method 1: Boiled (stronger taste)

1. Add 1 teaspoon of ajwain to 2 cups of water.
2. Bring it to a boil, then simmer for 3 to 5 minutes.
3. Strain into a cup and let it cool until warm.
4. Add a pinch of black salt if you like.

Method 2: Overnight soak (milder)

1. Add 1 teaspoon of ajwain to 2 cups of water.
2. Cover and leave it overnight.
3. Strain and drink it in the morning, warm or at room temperature.

Method 3: Steep in an infuser bottle (easy to carry)

1. Put 1 teaspoon of ajwain in the steel infuser of your bottle.
2. Boil the water and let it cool a little, then pour it in and close the lid. Our product page says not to pour boiling water straight in.
3. Lift the infuser out once the taste is strong enough for you.

This way the seeds stay in the infuser, so there is nothing to strain. You can sip it at your desk after lunch.

Best Time to Drink Ajwain Water

Quick answer: After a heavy meal is the most common time, for gas. Some people like it in the morning or at night. No study shows one time is best.

• After a heavy meal: the classic time, for gas and fullness.
• Morning: some people like a warm cup to start the day.
• Night: a warm cup can be part of a calm bedtime habit, and it is a popular choice during periods.

If you get acidity, avoid drinking it on an empty stomach. Try it after food instead. For acidity, also see which juices are good for gastric acidity.

Is Ajwain Water Safe During Pregnancy?

Quick answer: A pinch of ajwain in food is usually fine in pregnancy. A mild cup of ajwain water now and then may be okay. Avoid strong brews, ajwain oil and pills, and ask your doctor first.

Sources do not fully agree here, so it pays to be careful.

WebMD gives the strictest advice. It says ajwain "should be avoided by women who are pregnant or breastfeeding". It warns that compounds in ajwain have been shown to potentially cause birth defects or miscarriage (WebMD).

FirstCry Parenting says a pinch in dal, curry or paratha is generally considered safe. It says mild ajwain water is okay, with not more than 1 teaspoon in 2 cups (FirstCry).

Babynama puts it simply: "treat ajwain as a spice, not a medicine". It says to skip big doses, strong brews, ajwain oil and ajwain pills (Babynama).

Safe vs avoid: ajwain in pregnancy

Pregnancy me ajwain ka pani pina chahiye? Khane mein chutki bhar ajwain theek hai. Halka pani kabhi kabhi chal sakta hai, par pehle doctor se poochein. (In English: a pinch in food is fine, and a mild cup now and then may be okay, but ask your doctor first.)

First trimester: keep to food amounts. Talk to your doctor before you drink ajwain water often, or if you have a high-risk pregnancy.

9 month pregnancy me ajwain ka pani? Some women drink it in the last month in the hope that it will start labour. There is no proof that it does. The NHS says: "There are no proven ways of starting your labour yourself at home." It adds that herbal supplements "could be harmful to you or your baby" (NHS). FirstCry Parenting warns that large or medicine-like amounts of ajwain could cause the womb to tighten (FirstCry). So in the ninth month, keep to a pinch in food. Never use ajwain water to try to start labour, and ask your doctor before you drink it.

Pregnancy me jeera ajwain ka pani? No study has tested jeera and ajwain water in pregnancy. Babynama says not to mix many strong herbs together without guidance (Babynama). Keep any mix weak, have it only now and then, and ask your doctor.

Ajwain ka pani pine se pregnancy hoti hai? No. We found no study that shows ajwain water helps you get pregnant. If you are trying for a baby, talk to your doctor.

Ajwain Water for Babies

Quick answer: Do not give ajwain water to babies under 6 months. Breast milk or formula is all they need. For older babies, ask your paediatrician first.

Many families give a few drops of ajwain water for a baby's gas. But the NHS is clear: "Breast milk is the only food or drink babies need in the first 6 months of their life" (NHS).

If your baby seems to have a lot of gas or colic, talk to your paediatrician. They can check for other causes.

Side Effects: Who Should Be Careful?

Quick answer: Ajwain is safe for most people in food amounts. Be careful if you are pregnant or breastfeeding, if it gives you heartburn, or if you are giving it to a young child.

• Pregnant or breastfeeding: WebMD says to avoid it (WebMD). Keep to food amounts and ask your doctor.
• Babies under 6 months: no ajwain water at all.
• Heartburn: ajwain is strong. If it makes your acidity worse, make it weaker, drink it after food, or stop.
• On regular medicines: ask your doctor before you drink it every day.
• Severe or new pain: do not treat it at home. See a doctor.

Garam Pani Me Ajwain Ke Fayde

Quick answer: Garam pani me ajwain pine se gas aur pet phoolne me thodi rahat mil sakti hai. Periods ke dard me garam drink aaram de sakti hai. Par yeh dawa nahi hai.

Pani me ajwain dalne ke fayde kya hain? Ajwain ka pani gas, bloating aur badhazmi ke liye ek purana gharelu nuskha hai. Upar diye gaye studies thoda saath dete hain, par woh capsule ya mixed nuskhe par the. (In English: ajwain water is an old home remedy for gas, bloating and indigestion. The studies above give some support, but they tested capsules or mixed remedies.)

Ajwain, ginger and jaggery water is another popular mix. It is a tasty warm drink, but no study has tested this mix. For ginger on its own, see our juices for digestion guide. For another seed water, read about methi water.
