Cardamom Benefits: Ancient Spice, 2026 Research Update

Quick Answer

Cardamom is a warming spice used medicinally for over 4,000 years for digestion and lung health. Clinical trials from 2023–2026 now confirm cardamom (typically 1.5–3g daily) can modestly reduce blood pressure, inflammatory markers (CRP, IL-6, TNF-α), LDL cholesterol, and blood sugar (HbA1c, insulin resistance), with newer research also pointing to benefits for focus and cognitive performance.

As a warming spice, cardamom’s health benefits are genuinely fascinating — and unlike a lot of trendy supplements, this one has thousands of years of traditional use behind it, plus a growing stack of modern clinical trials backing it up. Cardamom supports natural immunity and works as a decongestant, antioxidant, expectorant, and carminative. Like most true spices, it also has meaningful anti-inflammatory effects.

In this post, I’ll walk through cardamom’s long history as medicine and the research proving out these benefits — including several newer studies published in 2023, 2025, and 2026 that weren’t available the last time I updated this post.

What is Cardamom?

Using cardamom is a rewarding experience because it has a wonderful aroma similar to ginger and its many gut health benefits and turmeric. Cardamom’s botanical name is Elettaria cardamomum, and it belongs to the Zingiberaceae (ginger) family.

Used in warming drinks, health supplements, savory dishes, and baked goods, this spice has a lot to offer. Cardamom fruits are also referred to as cardamom pods.

My favorite way to use cardamom pods is to crush them with my hands and steep them in hot water to make a simple cardamom herbal tea.

Cardamom’s History in Medicine

Cardamom has been used as medicine since ancient times in Greece, Rome, Egypt, and India. All of these cultures used it for similar purposes: digestive disorders and lung diseases. This consistent, independent use across cultures is itself a strong signal that it’s genuinely effective for these conditions. Hippocrates, the Father of Medicine, also acknowledged cardamom’s digestive benefits.

The use of cardamom as medicine in the United States goes back a long way, too. Tinctura Cardamomi Composita was a common spice blend used throughout the country, containing cardamom. According to the 1908 Textbook of Pharmacology, Therapeutics and Materia Medica, this tincture combined cardamom, cassia cinnamon, caraway, cochineal, and a base of alcohol.

Tinctures are simply medicines made by dissolving a drug in alcohol. Cardamom tincture was also described in the King’s American Dispensary in the late 1800s. This formula was found in pharmacies across the country and then largely vanished after the 1910 Flexner Report reshaped American medical education.

Tinctura Cardamomi Composita was historically used primarily for digestive ailments and lung disorders.

Why Use Cardamom?

Cardamom is rich in healthy antioxidants, and its complex chemistry of more than 20 distinct antioxidant compounds is more than the sum of its parts.

Among these healthy compounds are numerous terpenes that help decrease inflammation throughout the body.

Cardamom pods contain beneficial compounds such as:

  • Terpinyl acetate
  • Linalool
  • 1,8-Cineole
  • Limonene
  • Borneol

These healthy compounds can reduce nausea, reduce pain, have anti-anxiety effects, protect the heart, and more. Let’s look at why this complex, healthy spice helps the body — and what the newest research says.

Cardamom’s Aroma and Character

Each plant has a unique character. This is how we can easily tell the difference between cardamom and ginger, even though they’re closely related.

Specifically, cardamom has aroma characteristics that are spicy, rich, warm, aromatic, and slightly woody. When we focus on a plant’s aromatic character — like cardamom’s — we gain both emotional and physical benefits. That’s because cardamom’s volatile oils send direct signals to the brain that help dampen stress and inflammation. Research on cardamom aromatherapy and aerobic fitness shows that simply inhaling the aroma imparts measurable benefits for the lungs.

Cardamom also imparts feelings of invigoration and relaxation at the same time — a somewhat unusual combination among aromatic plants.

Cardamom has a distinctly warm character due to its chemical composition. This warming spice heats the body in a much more subtle way than hot peppers. As a relative of ginger, both spices bring heat to the body.

Since the earliest recorded history of Ayurvedic medicine, cardamom has been used for its warming qualities, which help bring balance back to the body when needed. Cardamom essential oil may improve circulation, which could help explain its warming effect on the body.

Traditional Uses of Cardamom

Cardamom has been used for hundreds of years as medicine. It was traditionally used for:

  • Treating heartburn
  • Intestinal spasms and irritable bowel syndrome (IBS)
  • Diarrhea, gas, and constipation
  • Liver health
  • Gallbladder complaints
  • Loss of appetite
  • Common colds and infections
  • Cough and bronchitis
  • Epilepsy
  • Headache
  • Urinary issues
  • High blood pressure

People also used cardamom for mental fatigue, loss of appetite, menstrual cramps, pancreatitis, colic, and more.

Scientifically Proven Benefits of Cardamom (2026 Research Update)

Cardamom is chemically complex. As a complex spice, it may support many parts of the body because it improves immune function, and acts as a decongestant, antioxidant, expectorant, tonic, carminative, and anti-inflammatory agent.

Cardamom Helps Digestion & Gut Health

Cardamom has anti-nausea effects in the body, so it’s excellent for reducing stomach distress.

Another potential benefit is that cardamom may reduce stomach ulcers, which can be caused by alcohol, aspirin, and NSAID-type drugs. In animal studies, cardamom reduced aspirin-induced stomach ulcer formation.

Newer lab research also backs up cardamom’s traditional reputation as a gut-protective spice. A 2021 study on green cardamom essential oil found it inhibited biofilm formation from E. coli O157:H7 by up to 85% and Salmonella Typhimurium by up to 100% at low concentrations, without any mutagenic activity — supporting its long history as a natural antimicrobial for gut infections. Follow-up research through 2025 has continued to confirm cardamom essential oil’s antibacterial and antibiofilm activity against gram-negative gut pathogens.

Cardamom also helps improve digestive function according to animal studies, working through numerous mechanisms — including a reduction in inflammation. While more human research is still needed, it’s a safe spice to try, since it carries GRAS status (generally recognized as safe).

Cardamom Reduces Blood Pressure & Inflammation

Spices are beneficial in so many ways, and cardamom is no exception when it comes to blood pressure and inflammation. A 2023 systematic review and meta-analysis of 8 randomized clinical trials found that cardamom supplementation significantly reduced hs-CRP, IL-6, and TNF-α — three of the most important inflammatory markers used in clinical practice — along with both systolic and diastolic blood pressure. A more recent 2026 clinical review builds on this, reporting an average systolic blood pressure reduction of roughly 8 mmHg at a dose of 3 grams daily.

In an earlier trial, patients with newly diagnosed high blood pressure who received 3 grams of cardamom powder daily for 12 weeks had significant improvements in blood pressure and markers of well-being.

Cardamom May Reduce Diabetes Complications

Like most spices and herbs, cardamom may be protective for people with diabetes. A review of 6 clinical trials and 14 cell studies concluded that cardamom has beneficial effects on reducing insulin resistance, oxidative stress, and inflammation.

A 2026 clinical review adds to this picture, reporting that cardamom supplementation at around 3 grams daily improved both HbA1c and HOMA-IR — two of the standard clinical markers used to track blood sugar control and insulin resistance. In an earlier study, cardamom also improved liver function and reduced cholesterol and blood glucose levels in diabetic rats — performing about as well as the prescription drug pioglitazone on these measurements.

Cardamom Reduces Pain

Muscle spasms can cause many kinds of pain, and cardamom may help here too.

One study found that cardamom reduces muscle spasms and pain by blocking the muscarinic receptor in rats — in other words, cardamom reduces nerve-induced pain. This kind of pain can occur almost anywhere in the body, including the stomach.

I’ve personally observed this pain-relief benefit. When I apply diluted cardamom essential oil to my temples, my tension headaches ease almost immediately.

Cardamom May Reduce Cancer Risk

Many culinary herbs and spices are well known to reduce cancer risk, and cardamom is no exception. One study showed that cardamom reduced the growth of colon cancer cells and triggered cancer cell death in mice.

Cardamom also reduced the appearance of non-melanoma skin cancers in rats.

More research is still needed, but it’s certainly safe to add cardamom to your diet for its numerous health benefits.

Cardamom May Protect the Heart

Thanks to its strong antioxidant effects, cardamom is protective for the heart. Early research shows that cardamom powder helps prevent high cholesterol, reduces oxidative stress on the heart, and reduces liver damage in animals fed a diet high in fat and sugar.

A 2026 clinical review takes this further, reporting that 3 grams of cardamom daily reduced LDL cholesterol by roughly 18–22% while protecting HDL (“good”) cholesterol — an effect likely related to cardamom’s fiber content binding to bile acids in the gut and reducing cholesterol reabsorption.

Early research even suggests cardamom may reduce the toxicity of the chemotherapy drug doxorubicin on the heart muscle. It also reduces blood pressure as described above and has a mild diuretic effect in animals.

As part of a healthy diet, cardamom can be a simple addition that supports a healthy heart.

Cardamom & Cognitive Function (New 2026 Research)

One of the more interesting additions to the cardamom research since I last updated this post involves black cardamom (Amomum subulatum) and cognitive performance. A 2026 randomized, double-blinded, placebo- and active-controlled trial published in Frontiers in Neuroscience found that a full-spectrum black cardamom extract improved focus, alertness, and executive function in healthy working adults — with effects that held up favorably even when compared against caffeine. This is early-stage research on a specific extract rather than whole cardamom spice, but it’s a promising new direction for a plant that’s mostly been studied for metabolic and digestive benefits.

Cardamom is Calming

Many spices and herbs have anti-anxiety effects and calming properties, and cardamom is among them.

One clinical study demonstrated just how calming cardamom can be — patients receiving cardamom powder over 12 weeks reported improved feelings of well-being. Cardamom also has relaxing and sedative effects according to animal studies.

Cardamom Helps Immunity and Lung Health

Like many spices, including cinnamon, cardamom essential oil has anti-fungal, anti-parasitic, and anti-bacterial effects. It even blocks certain viral enzyme functions in animal studies.

Inhaling cardamom essential oil before exercise improves lung function because it increases oxygen levels in tissues during exercise. It may also help combat asthma symptoms thanks to a bronchodilatory effect, though more research is still needed.

While the ideal dose and delivery method for immune support haven’t been fully worked out, cardamom is safe to use regularly as part of a preventative wellness routine.

Cardamom Reduces Bad Breath

Cardamom can reduce bad breath thanks to potent antibacterial and antifungal properties against odor-causing strains of Candida and Streptococcus.

How to Use Cardamom

You can use cardamom in any recipe you wish. It works especially well in curries, stir-fry dishes, for seasoning chicken and meats, and in baked goods. It’s also great as a tea, as described above. While ground cardamom can be pricey at retail grocery stores, you can buy cardamom pods in bulk at health food stores like Natural Grocers or on Amazon for very reasonable prices.

Cardamom in Coffee

My own daily habit: I add 4–5 whole cardamom seeds directly to my coffee grounds before brewing. It does two things at once — it mellows out the harshness and bitterness of the coffee, so the cup tastes noticeably smoother, and it gives me a small daily dose of cardamom’s compounds without any extra effort. It’s become one of those small rituals I don’t think twice about anymore, but the flavor difference is real if you haven’t tried it. This pairs nicely with coffee’s own research-backed health benefits — you’re essentially stacking two beneficial ingredients in one cup.

It’s especially worth trying if you drink decaffeinated coffee, which tends to fall flat and lack the fuller flavor of regular coffee. Cardamom fills in that flavor gap beautifully, while also boosting the cup’s health benefits and adding its own naturally relaxing effect — which pairs nicely with an evening or after-dinner decaf. If you’re particular about coffee quality (I am — mold and mycotoxin exposure from poorly processed coffee is more common than people realize), it’s worth reading my honest review of Terra Lava Coffee — it’s become my go-to for a clean cup, cardamom seeds and all.

Cardamom in Winter Infusions

In the winter months, I switch things up and make warming herbal infusions with cardamom pods — often alongside other warming spices — which fits with its traditional use as a spice that brings heat and balance to the body during colder weather.

Cardamom Supplementing and Dosing

Studies using cardamom supplements typically range from 1–4 grams daily of ground cardamom, with most of the clinical benefits described above studied at around 3 grams per day. You can buy cardamom as a retail spice or in capsule form.

Cardamom Myths

Aphrodisiac

Some websites claim that cardamom essential oil is an aphrodisiac. While this may be true, there’s no direct research at this point supporting the claim.

That said, indirect evidence suggests it may support sexual function by improving circulation. It may also heighten sexual responsiveness simply by improving overall well-being.

Rich in Minerals

Per gram, cardamom does contain minerals like magnesium, manganese, and copper. However, the amount of this spice you’d need to eat to get a meaningful dose of minerals isn’t realistic for most people.

Cardamom Safety

As mentioned, cardamom is generally recognized as safe.

As with anything, consult with your doctor before using cardamom medicinally, and use caution with cardamom supplements during pregnancy. If you take blood pressure medication, talk to your doctor before adding cardamom supplements, since the combined effect could lower blood pressure more than intended.

Make sure to discuss any new supplements in your healthcare routine with your healthcare provider.

One more note from my clinical practice: as with any food or spice, it’s possible to have a sensitivity to cardamom, and I always encourage people to pay attention to how their own body responds. That said, as a Certified LEAP Therapist who has reviewed MRT food sensitivity results for clients for years, cardamom sensitivity is genuinely rare in my observation compared to more common reactive foods and spices.

Frequently Asked Questions

Does cardamom really lower blood pressure?
Yes — a 2023 meta-analysis of 8 randomized clinical trials confirmed that cardamom significantly reduces both systolic and diastolic blood pressure, along with inflammatory markers like hs-CRP, IL-6, and TNF-α. A 2026 clinical review found an average systolic reduction of about 8 mmHg at 3 grams daily. If you take blood pressure medication, tell your doctor before adding cardamom supplements, since the combined effect could lower your blood pressure too far.

How much cardamom should I take daily?
Most clinical studies use 1–3 grams of ground cardamom per day, roughly half a teaspoon to one teaspoon. Start with smaller culinary amounts if you’re new to it, and consider a standardized supplement if you want a consistent, higher therapeutic dose.

Can cardamom help with blood sugar and insulin resistance?
Early research suggests yes. A 2026 clinical review found that cardamom supplementation at around 3 grams daily improved HbA1c and HOMA-IR, two standard markers of blood sugar control and insulin resistance, likely due to its anti-inflammatory compounds and antioxidant activity.

Does cardamom help with cholesterol?
Yes — a 2026 clinical review found that 3 grams of cardamom daily reduced LDL cholesterol by roughly 18–22% while protecting HDL (“good”) cholesterol. Cardamom’s fiber content is thought to bind to bile acids in the gut, reducing cholesterol reabsorption.

Is cardamom good for the gut and digestion?
Yes. Cardamom has traditionally been used for heartburn, IBS, gas, and constipation, and animal studies show it reduces stomach ulcer formation and improves digestive function. Newer lab research also shows cardamom essential oil inhibits biofilm formation from gut pathogens like E. coli and Salmonella.

Can cardamom improve focus or brain function?
A 2026 randomized controlled trial on black cardamom extract found improvements in focus, alertness, and executive function in healthy adults, with effects comparable to caffeine in some measures. This is newer, more preliminary research on a specific extract rather than the whole spice.

Can I add cardamom to my coffee?
Yes — adding a few whole cardamom seeds (about 4–5) to your coffee grounds before brewing is a traditional practice, popular in Middle Eastern and South Asian coffee preparations. It mellows out coffee’s natural bitterness and harshness for a smoother-tasting cup, while adding a small daily dose of cardamom’s beneficial compounds. It’s especially useful in decaffeinated coffee, which tends to taste flatter than regular coffee — cardamom fills in that missing flavor while boosting the cup’s health benefits and adding its own relaxing effect.

Can you have a sensitivity to cardamom?
Yes, as with any food or spice, it’s possible to have an individual sensitivity to cardamom. As a Certified LEAP Therapist who has reviewed food sensitivity (MRT) results for clients over many years, I can say that cardamom sensitivity is genuinely rare in my clinical observation compared to more commonly reactive foods and spices — but if you notice a reaction, it’s worth discussing with a practitioner who can help you confirm it.
