What is Cardamom?
Cardamom (Elettaria cardamomum) is a spice known for its aromatic seeds and pods, often referred to as the "queen of spices." It has numerous health benefits, including for cardiovascular and lung health.
This herb has been documented in ancient religious texts as a spice used both for health and devotional purposes.
The Cardamom herb is a perennial plant that typically grows to about 2-4 meters in height. It has long, lance-shaped leaves, small white or pale green flowers, and green pods containing small, black seeds.
Cardamom is native to the forests of the Western Ghats in Southern India. It thrives in tropical climates and is cultivated in countries like India, Sri Lanka, Guatemala, and Tanzania.
Primary Compounds of Cardamom
Cardamom contains several bioactive compounds, including:
• Cineole (Eucalyptol): Known for its antimicrobial and anti-inflammatory properties.
• Terpinene: An antioxidant with antimicrobial properties.
• Limonene: Provides antioxidant benefits and contributes to the aroma.
• Linalool: Has anti-inflammatory, antimicrobial, and sedative properties.

Health Benefits of Cardamom
Digestive Health
Cardamom is known for its carminative properties, which help reduce bloating, gas, and indigestion. It stimulates the secretion of gastric juices and aids in digestion.
Antioxidant Properties
Rich in antioxidants, cardamom helps protect the body from oxidative stress and free radical damage, contributing to overall health and disease prevention.
Anti-inflammatory
Cardamom has anti-inflammatory properties that can help reduce inflammation and associated pain, benefiting conditions like arthritis.
Respiratory Health
Cardamom is used to treat respiratory issues such as cough, asthma, and bronchitis. It acts as an expectorant, helping to clear mucus from the respiratory tract.
Oral Health
The antibacterial properties of cardamom make it effective in improving oral health. It is used to treat bad breath and prevent infections of the mouth and throat.
Blood Pressure Regulation
Some studies suggest that cardamom can help lower blood pressure due to its diuretic effects and high antioxidant content.
Antimicrobial Activity
Cardamom exhibits antimicrobial properties, making it effective against a variety of bacterial and fungal infections.
Clinical Research on Cardamom
Many studies have confirmed Cardamom’s benefits on human health. This is combined with thousands of years of human use by traditional doctors.
A 2024 Cochrane review of 12 human clinical studies found that Cardamom reduced triglycerides by an average of 14 mg/dL, reduced total cholesterol by 9 mg/dL, reduced C-reactive protein levels, and reduced inflammation levels. The researchers stated:
“In conclusion, cardamom consumption can improve specific cardiovascular metabolic biomarkers and potentially confer protective effects on cardiovascular health.”
A 2022 review of 6 human clinical studies involving 410 people showed that 3 grams of cardamom for between 8 weeks and 3 months significantly improved HbA1C levels and HOMA-IR (homeostatic model assessment – which measures insulin resistance) among those with blood sugar issues.
Another review of 14 studies also found that cardamom improved levels of insulin resistance, oxidative stress, inflammation, and cholesterol.
A 2020 study found that cardamom significantly aided in the reduction of nausea among pregnant women.
A 2022 review of research found eight studies that included 595 patients that tested cardamom. These studies found that cardamom significantly reduced diastolic blood pressure, reduced inflammation levels and reduced high-sensitivity C-reactive protein.
Other studies have shown similar effects, but also improved antioxidant status, and reduced ulcerative conditions. Another study showed it reduces toxoplasmosis infections.
