You'll know what it's like if at any time you've eaten a whole cardamom pod which is concealed in a dish of rice—the effect is sudden, resinous, a bit sweet and a bit sharp. That strong taste goes beyond flavour; among the many health benefits of cardamom people have used for centuries, the ones related to digestion, oral health, and general well-being are the ones tea drinkers, cooks, and those who explain remedies keep to. The following article looks at what cardamom does in the body, explains why Ceylon cardamom in particular has such a loyal following, and dand describes how it is grown in the central highlands of Sri Lanka before it gets to your spice jar.
What Makes Ceylon Cardamom Different
Cardamom is not native to Sri Lanka in the same way that cinnamon is — the majority of the world's supply comes from Guatemala and the Western Ghats in India. However, the plant, Elettaria cardamomum, did discover a true second homeland in the cool, wet highland areas of Sri Lanka at some point during the colonial era and has remained there ever since. For many generations small-holder farmers in these highland areas have grown it, generally on small plots situated between tea and other shade crops.
It is the growing conditions, not the fact that it belongs to a different species, that make ceylon cardamom special. Cooler nights, higher elevation, and steady rainfall cause the pods to mature more slowly, which tends to concentrate the essential oils that give cardamom its aroma and a greener, more herbaceous flavour than cardamom grown at lower altitudes. People who deal with both Indian and Sri Lankan cardamom usually say that the pods from Ceylon have, in addition to the typical citrus and pine notes, a cleaner eucalyptus flavour. Although this difference is slight, you will notice it if you use cardamom often.
From the Central Highlands: How Sri Lankan Cardamom Is Grown and Harvested
Most cardamom produced in Sri Lanka comes from the misty area that extends through Nuwara Eliya, parts of the Kandy district, and the foothills near the Knuckles Range—regions situated about 3,000 to 6,000 feet above sea level. Cardamom is a particular plant; it requires shade, humidity, and well-drained soil, which is why it is usually grown among larger trees rather than in open fields. Here, farmers generally allow it to grow alongside older tea bushes or within forest cover, keeping the soil cool and shielding the shallow root system from the sun's direct effects.
The plant is a perennial with rhizomes; it produces long, reed-like stems from a rootstock beneath the ground, and the flowers (and subsequently the pods) appear on separate panicles situated low down near the base instead of on the tall stems. As a result, harvesting has to be done by hand. The pickers go through the fields and select the pods one at a time, since not all the pods on a single plant ripen at the same time. An experienced picker learns to tell whether a pod is ripe by looking at its colour and texture rather than by referring to the calendar.
Once the pods have been picked, they are cleaned and dried — traditionally by sun-drying on raised mats, although many smaller operations now use low-heat drying to protect volatile oils that can be damaged by sun exposure. Grading then takes place, generally involving sorting the pods by size and colour into categories that are approximately equivalent to the international "bold green" and "extra bold" classifications applied to help keep them. This is slow and on a smaller scale than industrial cardamom estates in Guatemala, and this scale is one reason Ceylon cardamom remains a speciality item rather than a commodity crop.
Cardamom for Digestion: What Tradition and Research Say
This is where cardamom earns much of its reputation. In Ayurvedic and Sri Lankan traditional medicine, cardamom has for a long time been used after meals, either by chewing it whole, brewing it into tea or adding it to milk, with the aim of aiding digestion. The substances responsible for this effect, primarily cineole and terpinen-4-ol, are believed to relax the smooth muscle of the digestive tract, just as is the case with peppermint tea reducing bloating.
A number of small clinical studies have examined the effect of cardamom on functional dyspepsia (which is the medical term for chronic indigestion having no obvious structural cause) and have found that there are modest improvements in symptoms such as bloating and discomfort when cardamom is used together with other carminative herbs. This does not amount to proof that cardamom cures indigestion by itself, but it is in agreement with the centuries of anecdotal evidence. If you're asking about cardamom for digestion in particular, the easiest method is to drink a cup of tea made with two or three crushed pods after a heavy meal, or to add a pinch of ground cardamom to warm water.
It also mildly relieves gas and the unpleasant pressure that comes with it— which is probably why so many cuisines from South Asia and the Middle East pair cardamom with rich, heavy dishes such as biryani, kheer, and slow-cooked meats. The spice isn't included merely for flavour; it also has a digestive function.
Green Cardamom Benefits for Oral Health
If you chew a whole green cardamom pod, you will quickly notice it clears your mouth — and that's no coincidence. Cardamom has natural antibacterial properties, and laboratory studies have shown that its essential oils are active against some bacteria linked to bad breath and early gum irritation. This is one reason cardamom pods are used as a palate cleanser after a meal in South Asia, either included in paan or served in a small dish at the end of a meal in Sri Lankan and Indian restaurants.
One of the most immediate and obvious benefits of green cardamom that people mention is fresh breath—you don't need any study to verify it, you can tell within just a few seconds of chewing a pod. Some people brew cardamom into a mouthwash by crushing a few pods, steeping them in hot water, letting the mixture cool, then swishing it around before spitting it out. Although it can't replace regular dental care, it is a low-effort habit with a long history.
Antioxidant Properties: Why Cardamom Deserves a Place in Your Pantry
In addition to aiding digestion and supporting respiration, cardamom contains a reasonable amount of antioxidant compounds—namely flavonoids and phenolic acids—which help to neutralise free radicals in the body. Since damage caused by free radicals is connected with nutrition, research consistently links various things, such as general consumption and diets that include spices, to be linked with better long-term health results, even though no individual spice acts as a magical remedy by itself.
Cardamom is useful in this context because it is easy to include in your daily routine. Unlike certain antioxidant-rich ingredients that require a conscious effort to eat, cardamom can be easily added to tea, coffee, oatmeal, baked goods, and savoury dishes without significantly changing how you currently eat. Simply adding a cardamom pod to the coffee grounds when making your morning coffee the Sri Lankan way not only adds flavour but also provides a small daily dose of these compounds—no extra step is needed.
Is cardamom beneficial for blood pressure?
This is one of the more frequently asked long-tail questions, so it merits an honest response rather than a general statement. Some early research, including a small clinical trial involving people with stage-1 hypertension, showed that taking cardamom powder regularly over several weeks was linked to modest decreases in blood pressure readings. The researchers suggest that the potassium in cardamom and its weak diuretic effect might explain this — potassium helps to balance sodium levels and a reduction in fluid retention can ease the pressure on the walls of the blood vessels.
Even so, this represents only early-stage evidence and should not be seen as a substitute for prescribed treatment. For people who are managing high blood pressure, cardamom may well be a sensible inclusion in a healthy diet, but it must not be used in place of medication or medical advice. Individuals who have a diagnosed cardiovascular condition should consult their doctor before using cardamom as a therapeutic remedy rather than merely as a spice.
Bringing Cardamom Into Daily Life
You don't need to make any drastic changes to your diet. All you have to do is add a few whole pods to the rice when you're cooking it, put one or two crushed pods into your evening chai, and sprinkle a pinch of ground cardamom into your baking—this is exactly how cardamom has been used in Sri Lankan and South Asian homes for many generations. The health benefits come from consistency, not from treating cardamom as a medicine taken on its own.
Whole cardamom pods retain their oil much longer than pre-ground cardamom, which loses its strength within a few months of being ground. If you really want to get the most out of cardamom—whether you need it for flavour or its health benefits—it makes a real difference to buy whole, well-dried, well-graded pods and grind only small amounts as needed.
Cardamom requires a little patience, both in how it is grown in cool highland areas and in how it is used around the house. While it doesn't cure any condition, it is one of the more useful spices to keep in the pantry when you incorporate it daily into tea, coffee, and cooking.

Frequently Asked Questions
Is Ceylon cardamom the same as ordinary green cardamom?
It is the same species, Elettaria cardamomum, only grown in a different area. Ceylon cardamom has a slightly greener, more herbaceous smell because of the cooler, higher-altitude conditions in Sri Lanka. Although the flavour difference is slight, it is noticeable to those who frequently use cardamom when cooking.
How much cardamom is needed for the purpose of digestion?
There is no fixed amount, but if you crush two or three pods and let them steep in hot water for five minutes, you will get a mild, effective tea that most people get on well. Similarly, you can stir about a quarter teaspoon of ground cardamom into warm water or milk after a meal. Start with a small amount, then adjust to your taste, since cardamom's flavour is strong.
Can I have cardamom every day?
Cardamom is safe for most people when included as a normal part of their diet, whether used in tea, coffee, or cooking. As with any spice used for therapeutic purposes, the amount matters more than the quantity — a small number of pods each day is usually enough to get the flavour and traditional benefits without going overboard.
How can I tell whether cardamom is genuine and of good quality?
Look for pods that are whole and not split, with a bright green colour and a tight seal; pale, paper-like, or split pods are generally old or have been inadequately dried. A fresh pod should have a strong aroma as soon as you crush it. When you are purchasing in large quantities for business purposes, you can find out more about grading and sourcing on our wholesale inquiry page.
What is the best method for storing cardamom pods?
Store whole pods in a sealed container, away from light and heat, and keep them in a cool cupboard rather than by the stove. Whole pods will stay potent for about a year this way, but ground cardamom starts to lose its aroma after a few months, so only grind what you plan to use soon.
Do you export Ceylon cardamom overseas?
We ship Ceylon cardamom and other spices from Sri Lanka to customers and businesses worldwide. Documentation is arranged for commercial orders. If you have any questions regarding shipping times or the minimum quantities required, please get in touch with us via our contact page.
Can cardamom be of any help with bad breath?
Across South Asia, it is traditional to chew an entire pod after eating, and the antibacterial oils naturally present in cardamom help freshen breath quickly. Although it is a good habit, it works most effectively when combined with, not in place of, regular brushing and flossing.
Is it safe to give cardamom to somebody who is taking medication for high blood pressure?
Cardamom does not appear to have dangerous interactions with common blood pressure medications, so people on prescribed treatment should tell their doctor about any diet changes, such as regularly consuming cardamom. It should be seen as a helpful part of a healthy diet, not a replacement for medical care.
