❓ Quick Answers
What are the health benefits of cardamom?
Cardamom offers 10 evidence-based health benefits including lowering blood pressure, reducing inflammation (hs-CRP, IL-6, TNF-α), improving triglyceride levels, supporting blood sugar control, and enhancing antioxidant status. A 2024 meta-analysis of 12 RCTs with 989 participants confirmed these cardiovascular and metabolic benefits.[Evidence: A][3]
Can cardamom lower blood pressure?
Yes. A 2024 systematic review of 8 randomized controlled trials (595 patients) found that cardamom significantly reduces both systolic and diastolic blood pressure. The meta-analysis specifically noted decreased blood pressure in patients with metabolic syndrome and related disorders.[Evidence: A][1][2]
Is cardamom anti-inflammatory?
Yes. Multiple meta-analyses confirm cardamom significantly reduces key inflammatory markers including high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α). These effects were observed across 8-12 RCTs involving nearly 1,000 participants.[Evidence: A][1][3]
How much cardamom should I take daily?
Clinical trials consistently use 3 grams of cardamom powder daily, typically divided into doses taken with meals. This dosage has been studied for 8 to 12 weeks in human trials with good safety profiles. Start with smaller amounts and consult your healthcare provider before supplementation.[Evidence: B][4][9]
Can cardamom help with blood sugar control?
Research suggests yes. A randomized controlled trial of 83 type 2 diabetic patients found that 3g cardamom daily for 10 weeks significantly decreased HbA1c, fasting insulin, and HOMA-IR (insulin resistance marker) while increasing SIRT1, a protein linked to metabolic health.[Evidence: B][4]
🔬 How Does Cardamom Work?
Understanding how cardamom produces its health benefits helps you appreciate why this ancient spice has captured modern scientists' attention. The secret lies in its bioactive compounds and the multiple pathways they influence in your body.
Think of cardamom as a skilled orchestra conductor. Just as a conductor coordinates different instrument sections to create harmony, cardamom's active compounds—particularly 1,8-cineole (eucalyptol) and α-terpinyl acetate—coordinate multiple biological pathways to reduce inflammation, fight oxidative stress, and improve metabolic function.
Anti-Inflammatory Pathways
Cardamom works by downregulating cyclooxygenase-2 (COX-2), the enzyme responsible for producing inflammatory prostaglandins. Research demonstrates that cardamom extract significantly decreases COX-2 along with inflammatory cytokines IL-6 and TNF-α.[Evidence: C][8] This triple action on inflammatory pathways explains why multiple meta-analyses show reduced hs-CRP levels in human trials.[Evidence: A][1][2]
Antioxidant Mechanisms
Imagine your cells as a house, and free radicals as rust slowly damaging its structure. Cardamom's phenolic and terpenoid compounds act like a protective coating, neutralizing free radicals through DPPH scavenging activity.[Evidence: C][8] A systematic review confirmed that cardamom enhances antioxidant enzyme production while decreasing oxidative stress markers.[Evidence: A][7] In pre-diabetic women, 8 weeks of cardamom supplementation significantly reduced malondialdehyde (MDA), a key marker of oxidative damage (P=0.009).[Evidence: B][9]
Metabolic Effects
Cardamom appears to improve insulin sensitivity through multiple mechanisms. Research in type 2 diabetic patients showed increased SIRT1—a protein that regulates cellular metabolism and longevity—alongside improved HOMA-IR scores.[Evidence: B][4] Meta-analyses confirm significant triglyceride reduction (weighted mean difference: -20.55 mg/dL) across multiple RCTs.[Evidence: A][5]
Cardiovascular Protection
The blood pressure-lowering effects of cardamom likely stem from its influence on vascular function and its diuretic properties. A 2024 meta-analysis of 12 RCTs (989 participants) confirmed improvements in total cholesterol (WMD: -8.56 mg/dL), triglycerides (WMD: -14.09 mg/dL), and inflammatory markers—all contributing to cardiovascular protection.[Evidence: A][3]
📊 Dosage and How to Use
Clinical research provides clear guidance on cardamom dosage. Across all human trials, researchers consistently used 3 grams of green cardamom powder daily. Here's what the evidence shows:

| Pre-diabetes (inflammation, oxidative stress biomarkers) | 3 g/day | 8 weeks | [B][9] |
| Pre-diabetes (lipids, glycemic indices, blood pressure) | 3 g/day | 8 weeks | [B][10] |
| Non-Alcoholic Fatty Liver Disease (glucose, lipids, fatty liver grade) | 3 g/day (500mg × 2 capsules × 3 times/day with meals) | 3 months | [B][11] |
Recommended Daily Intake
Based on consistent evidence across all four randomized controlled trials, the recommended cardamom dosage is 3 grams daily for therapeutic effects. This dosage demonstrated safety and efficacy across 8-12 week study periods.[Evidence: B][4][9][10][11]
How to Measure 3 Grams
- Powder: Approximately 1 teaspoon of ground cardamom
- Whole pods: About 8-10 green cardamom pods (seeds crushed)
- Capsules: Follow manufacturer dosing (typically 500mg capsules, 6 per day)
Timing and Administration
In clinical trials, cardamom was typically divided into multiple doses taken with meals. The NAFLD study specifically used 500mg capsules, 2 capsules taken 3 times daily with meals.[Evidence: B][11] This approach may improve absorption and reduce any potential digestive discomfort.
⚠️ Risks, Side Effects, and Warnings
What the Research Shows
Clinical trials using 3 grams of cardamom daily for 8-12 weeks reported good tolerability. No serious adverse events were documented in studies involving type 2 diabetic patients, pre-diabetic women, or NAFLD patients.[Evidence: B][4][9][10][11]
Drug Interactions
Note: Limited clinical data exists on specific cardamom drug interactions. Theoretically, cardamom may interact with:
- Anticoagulants/blood thinners: Due to potential effects on blood clotting
- Diabetes medications: May enhance blood sugar-lowering effects
- Blood pressure medications: May have additive hypotensive effects
Always inform your healthcare provider about all supplements you're taking.
Pregnancy and Breastfeeding
Cardamom in food amounts is generally considered safe during pregnancy. However, medicinal doses (supplements) lack sufficient safety data for pregnant or breastfeeding women. Consult your healthcare provider before supplementing with cardamom during pregnancy or lactation.
Who Should Exercise Caution

Frequently Asked Questions
Is cardamom good for your heart?
Research strongly suggests cardamom supports cardiovascular health through multiple mechanisms. A 2024 meta-analysis of 12 randomized controlled trials (989 participants) found that cardamom consumption improved total cholesterol (WMD: -8.56 mg/dL), triglycerides (WMD: -14.09 mg/dL), and reduced inflammatory markers hs-CRP and IL-6. Additionally, systematic reviews confirm significant reductions in both systolic and diastolic blood pressure—key risk factors for heart disease. These combined effects on blood pressure, lipids, and inflammation suggest meaningful cardiovascular protection.
Can cardamom improve cholesterol levels?
Yes, but with important nuances. Meta-analyses show cardamom significantly reduces triglycerides, with one analysis reporting a weighted mean difference of -20.55 mg/dL across 5 RCTs. A more recent 2024 meta-analysis of 12 RCTs found improvements in both total cholesterol and triglycerides. However, the evidence for LDL and HDL changes is less consistent. In pre-diabetic women, cardamom reduced total cholesterol and LDL while showing protective effects on HDL. Results may vary based on individual health status.
Does cardamom have antioxidant benefits?
Yes. A systematic review of 14 studies (8 in vivo, 6 clinical) confirmed that cardamom enhances antioxidant enzyme production and decreases oxidative stress markers. Laboratory research demonstrates that cardamom's phenolic and terpenoid compounds exhibit DPPH free radical scavenging activity—a standard measure of antioxidant capacity. In human trials, 8 weeks of cardamom supplementation significantly reduced malondialdehyde (MDA), a marker of oxidative damage, in pre-diabetic women (P=0.009).
Is cardamom helpful for fatty liver disease?
Promising evidence exists for non-alcoholic fatty liver disease (NAFLD). A double-blind randomized controlled trial studied 87 overweight or obese NAFLD patients who took 3g green cardamom daily (500mg × 2 capsules × 3 times/day with meals) for 3 months. Results showed significant improvements: increased serum irisin (a beneficial hormone) and HDL cholesterol, decreased triglycerides, LDL cholesterol, fasting blood insulin, and HOMA-IR. Notably, fatty liver grade itself improved. This suggests cardamom may benefit those with fatty liver when combined with standard care.
What are the active compounds in cardamom?
Cardamom's health benefits come from several bioactive compounds. The primary active constituent is 1,8-cineole (also known as eucalyptol), a terpenoid compound responsible for cardamom's characteristic aroma and many of its therapeutic effects. Other important compounds include α-terpinyl acetate, various phenolic compounds, and flavonoids like quercetin and catechin. These compounds work synergistically to produce anti-inflammatory effects (downregulating COX-2, IL-6, and TNF-α) and antioxidant activity. Comprehensive reviews note that cardamom's effects on metabolic syndrome involve multiple mechanisms across these compound classes.
