Organic Cardamom Pods Powder
Also known as: Cardamom, green cardamom pods, organic cardamom powder, Elettaria cardamomum
Overview
Organic cardamom pods powder is derived from the seeds of Elettaria cardamomum, a plant native to South Asia. It is widely used as a spice and flavoring agent and also consumed as a dietary supplement. The powder contains bioactive compounds with antioxidant, anti-inflammatory, and antimicrobial properties. It is primarily used for supporting cardiovascular health, glycemic control, digestive health, and oral hygiene. Research on cardamom has matured to include several randomized controlled trials (RCTs) and systematic reviews, though the evidence base is still emerging and not fully conclusive.
Benefits
Cardamom supplementation has demonstrated several evidence-based benefits. For cardiovascular health, a systematic review and meta-analysis of RCTs indicated that green cardamom significantly reduced systolic blood pressure (SBP) by approximately 0.54 mmHg and diastolic blood pressure (DBP) by about 0.90 mmHg, with more pronounced effects in hypertensive individuals. A meta-analysis of seven RCTs also showed a significant reduction in triglyceride levels, although no significant impact on total cholesterol, LDL-C, or HDL-C was observed. Cardamom intake has been shown to reduce markers of systemic inflammation, such as high-sensitivity C-reactive protein (hs-CRP), particularly in studies lasting 10 weeks or longer. Furthermore, supplementation has been associated with up to a 90% increase in antioxidant capacity, supporting its role in reducing oxidative stress. While traditional uses include oral health benefits, such as freshening breath and promoting saliva flow, and essential oil studies show antimicrobial activity against oral pathogens, direct evidence from human trials on oral health is less robust. Evidence for direct glucose-lowering effects is limited.
How it works
Cardamom's therapeutic effects are attributed to its rich composition of polyphenols, flavonoids, and essential oils, including cineole and α-terpineol. These compounds exert antioxidant effects by scavenging free radicals and anti-inflammatory actions by modulating inflammatory cytokines like IL-6 and TNF-α. Its potential to lower blood pressure may involve improving endothelial function and reducing vascular resistance. The antimicrobial properties are thought to stem from its bioactive constituents disrupting bacterial cell membranes and inhibiting microbial growth. While the active constituents are absorbed primarily in the gastrointestinal tract, detailed bioavailability data are currently limited.
Side effects
Cardamom is generally considered safe when consumed in culinary amounts and appears safe in supplement doses up to 3 grams per day, as used in clinical trials. Adverse effects are rare, with mild gastrointestinal discomfort being occasionally reported. No significant drug interactions have been documented in high-quality studies. However, data on contraindications and use in special populations, such as pregnant or lactating individuals, are limited, and caution is advised due to insufficient evidence. Individuals with gallstones should also exercise caution, as cardamom may trigger colic.
Dosage
Effective dosages of green cardamom powder in clinical trials typically range from 1 to 3 grams per day. For measurable benefits in blood pressure and inflammation markers, supplementation duration of at least 8 to 12 weeks is often required. There is no established maximum safe dose, and doses exceeding 3 grams per day lack sufficient safety data from high-quality studies. The timing of supplementation relative to meals is not standardized, and specific absorption factors or cofactor requirements are not well characterized. It is advisable to start with a lower dose and gradually increase if tolerated, adhering to the clinically studied ranges.
FAQs
Is cardamom effective for lowering blood sugar?
Current evidence from meta-analyses does not support significant glucose-lowering effects of cardamom supplementation.
Can cardamom be used for hypertension?
Yes, modest reductions in both systolic and diastolic blood pressure have been demonstrated in adults with hypertension.
Are there side effects?
Cardamom is generally well tolerated, with minimal side effects like mild gastrointestinal discomfort reported at studied doses.
How long before benefits appear?
Benefits on inflammation and blood pressure typically appear after 8 to 12 weeks of consistent supplementation.

- https://pubmed.ncbi.nlm.nih.gov/32359750/ – This systematic review and meta-analysis of seven RCTs investigated the effects of cardamom on lipid profiles and glucose. It concluded that cardamom significantly reduced triglyceride levels but had no significant effect on total cholesterol, LDL-C, HDL-C, or fasting plasma glucose. The study highlighted moderate heterogeneity among included trials.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10804083/ – This systematic review and meta-analysis focused on the effects of cardamom on blood pressure and inflammatory markers. It found significant reductions in systolic and diastolic blood pressure, as well as hs-CRP, particularly with longer supplementation durations. The study noted stronger effects in hypertensive individuals and maintained a robust methodology.
