Cardamom: Health Benefits, What the Research Shows, and How to Use It

Cardamom is a spice made from the seed pods of plants in the ginger family, with a warm, slightly sweet, almost minty flavor. It’s used in curries, baked goods, teas, and coffee across South Asia, the Middle East, and Scandinavia, and it has a long history in traditional medicine.

Researchers have studied cardamom’s possible health effects, but most of the work so far has been in animals and laboratory dishes, and only a handful of small human studies exist. This guide separates what has been observed in people from what remains early-stage.

Blood Pressure

In humans: In one small study, 20 adults with newly diagnosed high blood pressure took about 3 grams of cardamom powder daily for 12 weeks. Their blood pressure fell into the normal range and their antioxidant status rose substantially. The study was small and had no placebo group, so it can’t prove cardamom was responsible.

In animals: Cardamom extract increased urine output and lowered blood pressure in rats, which suggests a possible diuretic effect.

Takeaway: Promising but preliminary. Cardamom isn’t a substitute for blood pressure medication or lifestyle changes.

Antioxidant and Anti-Inflammatory Effects

Cardamom contains plant compounds with antioxidant activity. In rat studies, cardamom extract inhibited several inflammatory compounds, and cardamom powder reduced liver inflammation in rats fed a high-carbohydrate, high-fat diet. Human evidence on its anti-inflammatory effects is limited.

Digestion and Stomach Ulcers

Cardamom has long been used in traditional medicine for nausea, indigestion, and stomach discomfort. In rat studies, cardamom extract reduced the number or size of aspirin-induced ulcers, in one case more effectively than a standard anti-ulcer drug at the dose tested. Test-tube studies also show activity against Helicobacter pylori, a bacterium linked to many stomach ulcers. None of this has been confirmed in people, so cardamom shouldn’t replace medical treatment for ulcers or H. pylori infection.

Cancer: Laboratory and Animal Research Only

In one mouse study, animals given a cancer-causing chemical developed fewer skin tumors when fed cardamom powder than untreated mice, and cardamom compounds slowed the growth of some cancer cells in test tubes. These are early laboratory findings. There is no evidence that eating cardamom prevents or treats cancer in humans, and it shouldn’t be treated as a cancer remedy.

Breath and Oral Health

Chewing cardamom pods after meals is a traditional way to freshen breath. Test-tube studies found that cardamom extract and oil can inhibit bacteria associated with tooth decay and reduce bacteria counts in saliva samples. Whether the effect holds up in everyday use hasn’t been established, so chewing a pod is a pleasant habit, not a replacement for brushing and flossing.

Antibacterial Activity

Laboratory studies show that cardamom extracts and essential oil can inhibit various bacteria and yeasts, including E. coli, Staphylococcus, Salmonella, and Candida. These were test-tube experiments, so they don’t show that eating cardamom treats infections.

Breathing and Exercise

One small study found that people who inhaled cardamom essential oil before walking on a treadmill took in more oxygen than a control group. Animal studies suggest cardamom extracts may relax airway muscles. This research is very limited, and cardamom isn’t a treatment for asthma. If you have asthma, keep using your prescribed medication.

Blood Sugar

In rats fed a high-fat, high-carbohydrate diet, cardamom powder helped keep blood sugar from rising. But in a human study where participants added cinnamon, cardamom, and ginger to black tea for eight weeks, only cinnamon improved blood sugar control. So there’s currently no good evidence that cardamom lowers blood sugar in people.

Liver, Anxiety, and Weight

Rat studies suggest cardamom may protect the liver, reduce anxious behavior, and affect body weight. In one study of 80 overweight or obese women with prediabetes, cardamom supplementation was associated with a modest reduction in waist size. These findings are too limited to draw conclusions.

Is Cardamom Safe?

In normal culinary amounts, cardamom is considered safe for most people.

• Supplements and extracts: There is no established dose, because most research has been in animals. Supplements aren’t strictly regulated, so if you use one, choose a third-party-tested brand and ask your doctor or pharmacist first.
• Pregnancy and breastfeeding: Food amounts are generally fine, but concentrated supplements and extracts haven’t been well studied.
• Gallstones: Cardamom may stimulate bile flow, so people with gallstones should check with a doctor before using large amounts.
• Medications: Anyone taking blood pressure, blood-thinning, or diabetes medication should talk to a doctor before using supplements.

How to Use Cardamom

• Add ground cardamom to oatmeal, yogurt, or baked goods
• Crush a pod into tea or coffee
• Use whole pods in rice dishes, curries, and stews
• Chew a pod after a meal as a breath freshener

Whole pods keep their flavor longer than ground cardamom, so grind seeds as needed.

Frequently Asked Questions

Does cardamom lower blood pressure?
One small human study found improvements, but it was uncontrolled and short. Larger trials are needed.

Is cardamom good for digestion?
It has a long traditional history for nausea and indigestion, and animal studies are encouraging, but human evidence is limited.

Does cardamom really freshen breath?
Its strong aroma masks odors temporarily, and lab studies show antibacterial activity, but there’s little research on lasting effects.

How much cardamom can I eat?
Culinary amounts are fine for most people. There’s no established therapeutic dose.

Can cardamom replace medication?
No. The research is early, and cardamom shouldn’t replace prescribed treatment.

The Bottom Line

Cardamom is a flavorful spice with interesting early research behind it, especially for blood pressure and digestion. But most of the evidence comes from animal and test-tube studies, and the few human studies are small. It’s a pleasant, safe addition to food for most people, not a proven treatment for any condition.
