Cardamom Health Benefits: What the Research Really Shows
Which benefits of cardamom (elaichi) are backed by clinical trials, which are myths, how much to take per day, and who should be careful. Based on meta-analyses of Elettaria cardamomum studies, reviewed by a medical reviewer.
⚡ The Short Answer
Cardamom is safe and healthy in food amounts. Trials on green cardamom show small improvements in blood pressure, inflammation markers and insulin, mostly at about 3 g a day. It does not help weight loss, and it is not a treatment for any disease.

Why Most Cardamom Health Articles Overpromise
Search for cardamom benefits and you will find claims of detox, fat burning, cured colds and better libido. Almost none of those come from human trials. The real research is smaller: a handful of randomized trials, pooled in meta-analyses, mostly using about 3 g of green cardamom daily for 8 to 12 weeks.
This guide rates every benefit by evidence strength, corrects the nutrition numbers using USDA data, and gives practical daily amounts. The research is on green cardamom (Elettaria cardamomum, elaichi). For black cardamom (badi elaichi) see our black cardamom guide; for the basics see what is cardamom.
“Cardamom’s aroma comes from 1,8-cineole and α-terpinyl acetate. These compounds are real and interesting, but a pinch in tea is a flavour choice, not a treatment.”
Editorial note — Medical review teamCardamom Nutrition Facts — Per Teaspoon and Per 100 g
USDA FoodData Central values for ground cardamomMany pages list nutrients “per gram” with inflated numbers. Here are USDA values for one teaspoon (about 2 g) and for 100 g. The per-100 g figures look impressive, but nobody eats 100 g.
| Nutrient | Per 1 tsp (2 g) | Per 100 g |
|---|---|---|
| Calories | 6 kcal | 311 kcal |
| Carbohydrates | 1.4 g | 68.5 g |
| Dietary fiber | 0.6 g | 28 g |
| Protein | 0.2 g | 10.8 g |
| Fat | 0.1 g | 6.7 g |
| Calcium | 7.7 mg | 383 mg |
| Iron | 0.3 mg | 14 mg |
| Magnesium | 4.6 mg | 229 mg |
| Potassium | 22 mg | 1,119 mg |
| Zinc | 0.1 mg | 7.5 mg |
Values are approximate and vary by origin and grade. Source: USDA FoodData Central, “Spices, cardamom”.
Reality check: at a teaspoon a day, cardamom gives well under 1% of your daily potassium, iron or magnesium. Think of it as a source of plant compounds and flavour, not a mineral supplement.
Cardamom Health Benefits Backed by Research
Each benefit rated by strength of human evidence“Moderate” here still means a handful of small trials. Treat every result as promising, not proven.
❤️
Blood Pressure
Limited–moderateWhat studies found
A meta-analysis of 8 trials (595 adults) found diastolic pressure fell by about 0.9 mmHg; systolic did not change significantly. Another 2023 analysis found drops of 1 mmHg or less. Most trials used about 3 g daily for 8–12 weeks.
≈ −1 mmHg
🛡️
Inflammation & Antioxidants
ModerateWhat studies found
A 2023 meta-analysis reported lower hs-CRP, IL-6 and TNF-α in people consuming cardamom. The authors warned that few trials exist, so larger studies are needed.
Markers ↓
🩸
Insulin Levels
LimitedWhat studies found
A 2025 meta-analysis of 8 trials found lower serum insulin, but no significant change in fasting glucose, weight or BMI. It is not a diabetes treatment.
Insulin ↓ only
🍵
Digestion: Bloating and Gas
Traditional useWhat studies found
Cardamom is a classic carminative and lab studies show gut-muscle relaxing effects, but good human trials are scarce. A cup of cardamom tea after a heavy meal is a low-risk habit. Just do not expect proven results.
😁
Breath and Oral Health
Lab studies onlyWhat studies found
Chewing a pod freshens breath, and cardamom oil shows antibacterial activity in the lab. No strong clinical trial shows it prevents cavities or gum disease.
Popular Cardamom Claims Without Good Evidence
Where each common claim actually stands| Claim | Where the science stands |
|---|---|
| Weight loss / fat burning | No significant effect on weight or BMI in a 2025 meta-analysis. |
| Detox of kidneys and liver | No human evidence. Your liver and kidneys already do this. |
| Cures colds, asthma, bronchitis | Cineole shows effects in lab studies. No proof cardamom treats respiratory illness. |
| Boosts libido or fertility | Based on animal studies and tradition. No reliable human trials. |
| Better skin, focus or sleep | Plausible from antioxidant and aroma effects but not properly tested. |
| Prevents gestational diabetes | Not supported. Never replace prenatal care with spices. |
Cardamom for Women, Men, Pregnancy and Children
Research does not show different benefits by sex. Safety advice differs.👩
For Women
The blood pressure, inflammation and digestive findings apply equally. Some trials used 3 g daily in overweight women with prediabetes. There is no solid evidence that cardamom balances hormones or eases period pain, though warm cardamom chai can be comforting.
👨
For Men
The same cardiovascular and metabolic findings apply. Libido claims lack human data, so do not rely on cardamom for sexual health concerns. See a doctor instead.
🤰
Pregnancy and Breastfeeding
Food amounts are generally considered fine. Medicinal amounts, extracts and supplements are not recommended because safety data is lacking. Check with your doctor or midwife, and never use cardamom to treat nausea or blood sugar problems on your own.
🧒
Children
There is no established medicinal dose for children. Tiny culinary amounts in milk, oatmeal or rice are normal in many cuisines. Avoid concentrated products and cardamom oil, and ask a pediatrician before using it for coughs or tummy aches.
Cardamom Pods vs Powder vs Extract
Which form to choose, and where tea fits in| Form | Best for | Notes |
|---|---|---|
| Whole green pods | Tea, milk, rice, curries | Keeps aroma longest. Crush before use. |
| Ground powder | Baking, smoothies, coffee | Convenient but loses aroma in months. See our cardamom powder guide. |
| Extract, capsules, tincture | Only under medical advice | Strength varies by brand. Not studied for long-term use. |
| Black cardamom | Smoky savory dishes | Different species with little health research. |
Cardamom tea benefits: tea is the easiest daily habit. It is calorie-free and may ease bloating for some people, but a cup holds far less than the 3 g used in trials. Try our cardamom tea recipes or cardamom tea for sleep. Out of pods? Use the seeds to ground conversion calculator.
How Much Cardamom Per Day Is Safe?
There is no official recommended intake. These are practical, evidence-based ranges.Everyday cooking and tea
Pinch – 1 tsp
Up to about 1 tsp ground (2 g), or a few crushed pods. Safe for most healthy adults.
Food amountStudied dose in adults
≈ 3 g / day
Roughly 1½ tsp ground, used in most trials for 8–12 weeks. Treat 3 g as a ceiling without medical advice.
Trial dosePregnancy / children
Food only
No established dose. Tiny culinary amounts only, and ask your doctor before anything more.
No set doseTip: introduce cardamom gradually. Large spoonfuls of dry powder can irritate the stomach. Extracts and capsules: follow the label and ask your doctor first.
Cardamom Side Effects and Who Should Be Careful
Very well tolerated in food amounts. Ask a professional if any of these apply.- Gallstones: cardamom seed may trigger gallstone colic. Stay at food amounts.

- Allergy: avoid it if you react to cardamom or other ginger-family plants. Contact dermatitis has been reported.
- Blood pressure or diabetes medication: cardamom may add to the effect, so monitor your levels.
- Blood thinners or planned surgery: lab studies suggest mild anti-platelet activity. Tell your doctor about concentrated use.
- Reflux (GERD): spices can trigger heartburn in some people.
- Kidney disease: ask your doctor before using extracts.

Cardamom Health Benefits — Frequently Asked Questions
Straight answers based on the researchYes, in food amounts it is safe for most people and adds antioxidants. Trials show small benefits for blood pressure, inflammation and insulin, but the studies are small and short, so cardamom is a helpful extra, not a treatment.
There is no official limit. Cooking amounts (a pinch to about 1 tsp ground, or a few pods) are fine. Most trials used about 3 g daily for 8–12 weeks, so 3 g is a sensible ceiling without medical advice.
Only slightly. Pooled trials show average drops of about 1 mmHg or less. It should never replace medication.
It is a low-calorie way to enjoy cardamom and may ease bloating. A cup gives much less than the 3 g used in studies, so expect comfort more than medical effects.
Food amounts are generally considered fine. Supplements, extracts and large amounts are not recommended because safety data is lacking. Ask your doctor or midwife first.
Per 100 g yes (about 1,119 mg), but a teaspoon has only about 22 mg, so it is not a meaningful potassium source in normal use.
No. A 2025 meta-analysis of eight trials found no significant effect on body weight or BMI.
Stay at food amounts if you have gallstones, are pregnant or breastfeeding, or are allergic to ginger-family plants. Ask your doctor before concentrated use if you take blood pressure, diabetes or blood-thinning medication.
