In Unani and Ayurvedic systems, Black Cardamom is used as a medicine for the treatment of several gastrointestinal disorders.

It was revealed in an experiment that black cardamom had significantly inhibited gastric lesions induced by ethanol.

One of its fractions tested had also increased the wall mucus showing a protective sign on the gastric mucosal barrier that plays a vital role in protecting the stomach wall against gastric acids and digestive enzymes (1,2).

It may help with Dental Caries

Tooth decay or Dental caries is mainly caused by bacteria. When we eat certain foods, bacteria react with them and produce acids that can damage the teeth surface leading to cavities.

Invitro study had shown that Black cardamom has potential anti-microbial activity against some of the bacterial species that can cause dental caries.

Among different bacterial species tested, Staphylococcus aureus was found to be one of the most susceptible ones followed by Streptococcus mutans, Saccharomyces cerevisiae, and Candida albicans (3).

Anti Inflammatory Activity

In research conducted, Fruit extracts of black cardamom were orally administered to the rats subjected to carrageenan induced paw edema to know their anti-inflammatory activity.

The results had revealed that both the extracts tested (methanolic and aqueous) had shown significant anti-inflammatory activity in a dose dependent manner and the results obtained were also comparable to the standard drug Ibuprofen (4).

Analgesic Activity

Since ages, Black cardamom is used as a folk medicine to treat various health problems and also as a substance that can relieve pain.

In a study conducted, to know the analgesic activity of black cardamom, it was revealed that methanol and ethyl acetate extracts of the seeds were known to exhibit significant analgesic activity when tested using the hot plate method and writhing method (5).

It can help against Stress

Large cardamom can act as an excellent adaptogen, a substance that can help to counteract the stress related effects on the body.

In an experimental study, guinea pigs were divided into three groups and were subjected to stress by allowing them to swim till exhaustion. On the other hand, they were injected with Adrenaline, a drug that can intensify blood pressure and heart rate (6).

Injecting adrenaline had significantly reduced the swimming time in all three groups.

However, when compared with the normal control group, animals that received Black cardamom has less effect (44.77%) than that received Ashwagandha (32.84%).

It may be used to treat Ischemic Heart Disease

Large Cardamom may be useful for patients with ischemic heart disease as it may help to reduce the risk factors associated with it.

Thirty male individuals with this disease were studied by dividing them into two groups with fifteen each for 12 weeks, in which one group was given 3 grams of cardamom powder and the other with a placebo.

Blood samples of the patients of both the groups are collected at 6 weeks and 12 weeks during the study and tested for various factors.

The study found that the administration of black cardamom had significantly reduced the lipids that tend to form deposits in arteries and also enhanced the fibrinolytic activity (the process of stimulation the blood clot dissolution) and serum total antioxidant status that help to reduce the risk associated with the disease.

The placebo group did not show any change in the parameters tested (7).

Hepatoprotective Activity

In Ayurveda and several other traditional systems, Black cardamom is used as a medicine for treating various liver disorders.

Several studies conducted had also revealed that black cardamom seeds possess excellent hepatoprotective properties.

Treatment with black cardamom methanolic extract and silymarin in experimental rats that were subjected to 20% ethanol induced liver damage had shown that the treatment had significantly prevented the various changes caused by ethanol to the liver, indicating that the extract of this plant seeds has excellent hepatoprotective activity.

The study also said this protective nature of black cardamom may be due to its phytochemicals like flavonoids, glycosides, and terpenoids as an individual or by the combined effect (8).

To evaluate the hypolipidemic activity of the Black cardamom fraction, Hyperlipidemia was induced in experimental animals by feeding them with an atherogenic diet for 120 days.

Which lead to an increase in serum total cholesterol, LDL and VDL, etc., and the good cholesterol HDL was decreased.

Large cardamom administration in those animals had shown a significant reduction in the total cholesterol, LDL, VDL levels also with an increased level of HDL (10).

It has Free Radical Scavenging Nature

An experiment had shown Amomum subulatum fruits reported to possess a significant radical scavenging activity.

It was found that ethyl acetate soluble fraction isolated during the experiment had shown the highest radical scavenging activity against DPPH.
