6 Emerging Benefits and Uses of Carom Seeds (Ajwain)

Carom seeds are the seeds of the ajwain herb, or Trachyspermum ammi. They’re common in Indian cuisine.

Although referred to as “seeds,” carom seeds are the fruit of the ajwain herb.

They’re slightly green to brown in color and have a pungent, bitter taste. They look similar to cumin seeds, but their taste and aroma are closer to that of thyme.

They’re often sold as whole seeds but can also be ground into a powder and used as a cooking spice.

Carom seeds are incredibly nutritious, being rich in fiber, antioxidants, and other vitamins and minerals. Because of this, they have been associated with health benefits and long been used in traditional Indian medicine practices.

Here are the top 6 health benefits and uses of carom seeds.

1. Fight bacteria and fungi

Carom seeds have powerful antibacterial and antifungal properties.

This is likely attributed to two of its active compounds, thymol and carvacrol, which have been shown to inhibit the growth of bacteria and fungi (1Trusted Source, 2Trusted Source, 3Trusted Source).

Test-tube studies indicate that these compounds may combat potentially harmful bacteria like Escherichia coli (E. coli) and Salmonella — culprits of food poisoning and other health conditions (2Trusted Source, 3Trusted Source, 4Trusted Source).

One test-tube study observed that carom seeds were more effective against multidrug-resistant strains of bacteria and fungi including Candida albicans, Candida krusei, and Streptococcus mutans compared to other solvents (5Trusted Source).

However, further research is needed to examine how the seeds may affect the growth of bacteria and fungi in humans.

2. Improve cholesterol levels

Animal research indicates that carom seeds may lower cholesterol and triglyceride levels. High cholesterol and triglyceride levels are risk factors for heart disease.

In one rabbit study, carom seed powder reduced total cholesterol, LDL (bad) cholesterol, and triglyceride levels (6).

Similarly, a study in rats found that carom seed extract was effective in lowering total cholesterol, triglyceride, and LDL (bad) cholesterol levels while also increasing levels of heart-protective HDL (good) cholesterol (7Trusted Source).

Still, in both studies, carom seed powder only proved effective at treating high cholesterol levels when used in high doses that you won’t get from eating the seeds through a normal diet.

More studies are needed to evaluate how the seeds may affect cholesterol levels in humans.

3. May lower blood pressure

High blood pressure, or hypertension, is a common condition that increases your risk of heart disease and stroke (8Trusted Source, 9Trusted Source).

Traditional treatment involves the use of medications like calcium-channel blockers. These blockers prevent calcium from entering the cells of your heart and relax and expand blood vessels, resulting in lower blood pressure (10Trusted Source).

Some research indicates that thymol — a major component of carom seeds — may have calcium-channel-blocking effects and could help lower blood pressure levels.

For instance, studies demonstrate that carom seed extract reduces blood pressure levels in rats (11Trusted Source, 12Trusted Source).

However, research on carom seed’s effectiveness in lowering blood pressure levels is still limited. Further studies are needed to understand how the seeds may affect blood pressure in humans.

4. Combats peptic ulcers and relieves indigestion

Carom seeds are commonly used as a household remedy for digestive issues in Ayurvedic medicine (13Trusted Source).

Some studies show that carom seed extract may combat peptic ulcers, which are sores of the esophagus, stomach, or small intestine (1Trusted Source, 13Trusted Source).

For example, a two-week rat study observed that treatment with carom seed extract improved stomach ulcers caused by ibuprofen (14).

The study found that the effect of the extract was comparable to that of a common medication used to treat peptic ulcers (14).

Carom seed extract may also help prevent and treat gas and chronic indigestion. Indigestion is categorized as persistent pain and discomfort in the upper part of your stomach. Delayed stomach emptying is one of the perceived causes of indigestion (15Trusted Source).

Interestingly, carom seed spice has shown to accelerate the process of food passing through the stomach in rats, which may help improve indigestion. Still, this has not been proven in human studies (16).

5. May prevent coughing and improve airflow

Some evidence suggests that carom seeds may provide relief from coughing.

Though research is scant, one study in guinea pigs found that carom seeds produced an anticoughing effect greater than that of codeine, a common medication used to treat coughs (17Trusted Source).

Carom seeds may also improve airflow to the lungs.

In a study in people with asthma, treatment with 0.057–0.113 ml per pound (0.125–0.25 ml per kg) of body weight of carom seed extract increased airflow to the lungs 30–180 minutes after administration (18Trusted Source).

The effect was comparable to that of theophylline, a common asthma medication (18Trusted Source).

Ultimately, more research is needed to better understand the effect of carom seeds on coughing and other respiratory symptoms in humans.

6. Has anti-inflammatory effects

Inflammation can be good or bad. Short-term inflammation is your body’s natural way of protecting against illness or injury.

On the other hand, chronic inflammation can have negative effects on your body and increase your risk of certain diseases (19Trusted Source).

Carom seeds have been shown to have anti-inflammatory effects and may reduce inflammation in your body.

A rat study found that supplementing with carom seed extract had significant anti-inflammatory effects (20).

Similarly, a recent study found that arthritis-induced rats given carom seed extract for 21 days had improved inflammatory markers, such as lowered elastase levels, which is an enzyme associated with inflammation (21).

While more research is needed, scientists concluded that carom seed extract may have potential as a treatment for inflammatory disease (21).

re carom seeds safe?

For most people, carom seeds are safe to consume.

Still, pregnant or breastfeeding women should avoid them due to potentially dangerous effects on fetal health, including potential birth defects or even miscarriage (1Trusted Source).

If you’re pregnant, it’s important to consult with your healthcare provider before taking carom seeds in seed, extract, or powdered form.

Additionally, anecdotal reports of nausea after ingesting high doses of carom seeds have been noted. For this reason, the seeds should be eaten in small amounts.

The bottom line

Carom seeds have long been used in traditional Indian cuisine and Ayurvedic medicine.

They have been shown to possess antibacterial and anti-inflammatory effects and may be effective in treating peptic ulcers and reducing blood pressure and cholesterol levels.

Still, most evidence is from animal and test-tube studies, and further research is needed to better understand the benefits of carom seeds on human health.

Carom seeds are considered safe for most people. However, the seeds are unsafe for pregnant women as they have been associated with harmful effects on fetuses.
