Jamun Benefits & Medicinal Uses

Jamun fruit pulp, seed with seed coat and kernel, alone kernel, bark and leaves all parts are used in many health conditions. We discuss its benefits and medicinal uses according to different parts of the Jamun Plant. Here are some common benefits.

Nutrients in Jamun

The composition of Jamun fruit mainly depends on the region where it is cultivated and on the climate of that particular region. Climate plays a very important role on the composition of minerals rather than that of the vitamins. The major minerals present in Jamun pulp as well as seeds include:

  • Sodium
  • Potassium
  • Magnesium
  • Calcium

Sodium and potassium are two important electrolytes that are required for regulating blood pressure whereas, magnesium and calcium are vital for strong bones and teeth. Besides this, Jamun pulp and seeds also contain other minerals such as zinc, phosphorus, iron, copper, manganese, chromium and chlorine. It also contains a variety of vitamins such as vitamin A, thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), folic acid (vitamin B9) and vitamin C.

In addition to this, Jamun also contains an appreciable quantity of protein. Amino acids present in Jamun include:


Jamun pulp also contains sugars such as galactose, fructose, glucose, maltose and mannose. Of all these sugars, maltose is present in the highest quantity.

Antioxidant Properties

Jamun fruits are used to cure a number of ailments. Such beneficial effect is possible due to the presence of antioxidants in it. Scientific studies have found that skin or peel of Jamun fruit has more antioxidants as compared to Jamun pulp. Therefore, it is better to eat whole Jamun in order to get more antioxidants. Antioxidants present in Jamun include:


These antioxidants along with other health promoting compounds scavenge free radicals and combat oxidative stress. Extracts of Jamun seeds have antioxidant potential and it works by trapping free radicals such as superoxide, hydroxyl, and lipid peroxide. β-carotene, a potent antioxidant present in Jamun inhibits auto-oxidation and thus protects the body against various harmful diseases. Research has shown that oral administration of Jamun seed extract lowered oxidative stress and increased the level of antioxidant in the body.

Heart Diseases

Hypertensive and individuals with altered lipid profile are at an increased risk of developing heart diseases. Research has shown that Jamun fruit and its other plant parts are very effective in reducing the risk of such diseases and thus provides protection to the heart. Individuals with heart diseases are often in the state of oxidative stress. Reduction in oxidative stress further reduces the risk of heart diseases. Jamun possesses antioxidant activity which in turn combats oxidative stress. Besides this, Jamun extracts also protect the cardiac cells against the harmful effect of free radicals.

Jamun Fruit Pulp Benefits & Uses

Jamun Fruit Pulp is juicy and has amazing sweet and astringent taste. It imparts crimson black color on the tongue. It is nutritious and rich in phytochemicals and antioxidant, which helps to maintain the health.

Specific Time to Eat Jamun & Drink Jamun Juice

According to Ayurveda, if Jamun fruit pulp or Jamun juice is taken before food, then it increases VATA DOSHA in the body. To prevent it, it should be taken in PITTA KALA (Time when Pitta is predominant in body and nature). The best time to eat Jamun is afternoon from 12:00 PM to 3:00 PM.

Poor Appetite

Jamun fruit juice is beneficial for improving appetite. It is used in following way for this.

Jamun fruit juice20 ml
Trikatu Churna500 mg
Trikatu Churna should be added in 4 teaspoons (20 ml) Jamun fruit juice for improving its digestive stimulant action and preventing abdominal distension.


Jamun fruits are beneficial for reducing abdominal fullness, abdominal discomfort, and burning sensation in the abdomen. For this, a handful fruits can be eaten and Sonth (dried ginger root powder) should also be taken with water after consuming the Jamun fruit for maximum benefits.

Chronic Colitis

Jamun fruits reduce the inflammation of the colon linings and astringent action reduces the frequency of bloody stools. It is effective when a patient passes stool with a feeling of burning pain and mucus content may also be present in the stools.

Rectal Bleeding (Bleeding Diarrhea)

The astringent action of Jamun fruit reduces bleeding in the stools and reduces the frequency of loose stools. In Ayurveda, it is advised to drink its juice in a dosage of 20 ml along with Gulkand (2 teaspoons).


Research has shown that Jamun has anti-tumor activity in which it inhibits the growth of the tumor. Research has also found that treatment with Jamun reduced the incidence of the tumor as well as reduced the size of the tumor. This effect is possible due to the ability of Jamun to detoxify harmful cancer-causing cells. It also plays a protective role by inhibiting the action of free radicals and by combating oxidative stress.

Furthermore, it is also observed that Jamun reduces the multiplication of cancer-causing cells and hence, it reduces the population of such cells. Jamun extract also prevents the spread of cancer to other organs of the body. These effects of Jamun are attributed to its high antioxidant and anti-inflammatory effects. (Reference)

Liver Protective Effect

Excessive exposure to toxins, infectious agents, and drugs to the liver causes damage and injury to the liver. It leads to the generation of free radicals that impair the normal function and structure of the liver. During this period, levels of liver enzymes increase and blood sugar levels also rise as glycogen is stored in the liver. It was found that treatment with Jamun extract reduced the level of liver enzymes as well as blood sugar levels. Furthermore, it restored the normal function and structure of the liver. This result indicates the Jamun extract possesses liver protective (hepatoprotective) activities.

Research has also shown that toxic agents react with liver cells and thus, lead to hardening of the liver. Such change in the structure alters the normal functioning of the liver. It has been observed that Jamun acts as a liver tonic and thus, protects it against damage. Jamun also contains antioxidants that scavenge the free radicals, which are formed in the liver during liver damage and thus, it combats oxidative stress. It was even found that low dosage of Jamun extract does not possess liver protective effect. Therefore, more human trials are required to confirm the dosage of Jamun extract for humans with liver diseases and its safety profile also needs to be determined.

Jamun Seeds’ Benefits & Uses

Jamun Seeds are beneficial in diabetes mellitus and some other diseases, as discussed below.

Type-2 Diabetes Mellitus

Jamun seeds are widely used for the treatment of type-2 diabetes mellitus in India and many other countries. Jamun bark, seeds, and leaves are utilized for the management of blood sugar levels. Jamun seeds reduce postprandial sugar level as well.

A rat study found that treatment with Jamun extract for 15 days significantly lowered high blood sugar levels. An active compound named ‘MYCAMINOSE’ present in Jamun works similar to an anti-diabetic drug called GLIBENCLAMIDE and it stimulates the secretion of insulin from pancreatic beta-cells. Furthermore, Jamun seeds lower blood sugar levels by potentiation of insulin effect by either increasing the secretion of insulin or by increasing its release from the bound form. Thus, the hypoglycemic properties of Jamun seeds may be due to its insulin stimulatory effects.

Another interesting research showed that Jamun seed extract inhibits the enzyme that converts carbohydrates into glucose on digestion. Such inhibition prevents a sudden rise in the blood sugar levels after a meal. Fiber present in Jamun seeds such as cellulose, hemicellulose and lignin had a little impact on blood sugar.

Some studies have found that high antioxidant content of Jamun combats oxidative stress and thus reduces hyperglycemia. In addition to this, Jamun also increased the storage of glycogen in liver and muscles and thus reduced the amount of glucose in the blood. Jamun also increases the activity of glucose transporter and thus, helps to transport glucose in the liver and muscles.

In diabetes mellitus, Jamun seeds are used in dosage of 1 to 2 grams thrice daily. For increasing its anti-diabetic and anti-hyperglycemic effects, the following combination is very helpful.

Jamun seed powder100 grams
Methi (Fenugreek) seed powder100 grams
Amla Powder (Amla Churna)100 grams
Bilva Leaf Powder100 grams
Gurmar (Gymnema Sylvestre) Powder100 grams
Neem Leaf Powder50 grams
Chirata Powder50 grams
Haldi (Turmeric) Powder50 grams
Trikatu Churna50 grams
Dosage: 1 teaspoon with warm water thrice daily 30 minutes before meal
This mixture improves insulin sensitivity as well as boosts the insulin secretion.
In initial stages, this Jamun seed combination works awesome without any other medicines. If the patient is taking allopathic medicines, then the need to monitor blood sugar level and reduce the dosage of allopathic medicines gradually as per achievement of good control on blood glucose level.
Restricted Diet: Potatoes, Rice, Sugar, Sweets, and other high glycemic foods
Recommended Diet: Pulses, Barley and Gram flour Chapatti, Cow’s Milk, Green Vegetables and other low glycemic foods

Glycosuria (Glucosuria)

Jamun seed powder is an excellent solution for Glycosuria (sugar in urine). In this case, the similar combination can be used as described above under heading Diabetes Mellitus.

Peptic Ulcers

The gut-protective role of Jamun is due to the presence of tannins in it. Several drugs cause damage to the inner lining of the gut. Tannins present in Jamun have shown to reduce the damage caused by drugs and also reduces the concentration of free radicals in the gut. Drugs induce gastric damage and ulceration through the excess generation of reactive oxygen species. Many studies have claimed that Jamun has antioxidant activities. Furthermore, research has shown that Jamun extracts have an anti-inflammatory and anti-ulcer effect. Jamun also helped to restore mucus, a viscous layer that protects the inner lining of the stomach against harmful effects of drugs and acid. (Reference)

Another study observed that Jamun seed extract played a beneficial role in the treatment of aspirin-induced peptic ulcers. The study revealed that Jamun seeds possess anti-ulcer and antioxidant properties that protect against stomach ulcers. Aspirin induces the formation of free radicals that cause injury to the inner lining of the stomach. The study further revealed that Jamun seeds significantly reduced oxidative stress parameters and improved the antioxidant enzymes such as catalase, glutathione, and superoxide dismutase. Thus, Jamun seeds exhibited a relaxing effect on the gut and helped in the treatment of stomach ulcers. (Reference)

High Cholesterol Levels

Many studies have shown that Jamun extracts have excellent antilipemic activity and it helps to lower high blood cholesterol levels. Treatment with Jamun seed extract helped to reduce high levels of total cholesterol, LDL (low-density lipoprotein) cholesterol, VLDL (very low-density lipoprotein) cholesterol (unhealthy) and triglyceride levels. Such effect of Jamun seed extract is due to the presence of health-promoting compounds such as alkaloids, flavonoids, saponins, tannins, phenols, gallic acid and ellagic acid. Furthermore, Jamun also significantly increased the level of healthy cholesterol- HDL (high-density lipoprotein).

Another study observed that Jamun seed extract contains water soluble fiber that significantly reduced the level of cholesterol in the liver as well as in the heart. It also increased the excretion of bile acids, thus more cholesterol is used for the formation of bile rather than being stored in the body. Such activity was due to its gelling property of fiber that gets bound to bile acid and increases its excretion in the feces.

Jamun Seed Kernel

Jamun Seed Kernels are specially used in following cases:


Astringent action of Jamun seed kernels helps to treat diarrhea. It is more beneficial in cases of chronic diarrhea. In chronic diarrhea, Jamun Kernels are used in following way:

Jamun Seed Kernel Powder100 grams

Jamun Tree Leaves
Jamun Tree Leaves

Jamun Leaves’ Benefits & Uses

Jamun leaves are useful in mouth ulcer, bleeding piles, diarrhea, typhoid fever, etc.

Antimicrobial Properties

Diseases caused by microbes and bacteria have increased tremendously. Therefore, natural agents are required to get rid of these microbes and to protect the body against infectious diseases. One interesting research observed the effect of Jamun leaves against drug resistant gram positive and gram negative bacteria. This positive effect is attributed to the presence of flavonoids, glycosides, steroids, alkaloids, saponins, phenols and tannins. These phytochemicals present in Jamun leaves confer antimicrobial effects.

Flavonoids present in Jamun have a natural ability to modify the body’s reaction to the virus and allergies and thus they possess anti-microbial and anti-allergic properties. Steroids and tannins also possess strong anti-microbial activities. Researchers have also claimed that tannins have the ability to inhibit HIV replication selectively.

The study results revealed that Jamun leaves exhibited antibacterial activity against:-

  1. Bacillus Subtilis (causes food poisoning)
  2. Salmonella typhi (causes typhoid)
  3. Pseudomonas Aeruginosa (causes infection in lungs, kidney, and urinary tract)
  4. Escherichia coli (causes food poisoning)
  5. Proteus Vulgaris (causes urinary tract infection and wound infections)

Therefore, the remarkable activity of Jamun leaves may be due to high concentration of phytochemicals and other health promoting compounds present in it.

Hypertension (High Blood Pressure)

Anti-hypertensive treatment is required to lower the level of high blood pressure and to reduce the risk of hypertension-related complications such as heart diseases and stroke. Studies have shown that a reduction of 5 mm Hg in systolic blood pressure reduces the risk of death associated with heart disease by 7%. Treatment with Jamun leaf extract reduces vasoconstrictor agents that constrict the blood vessels and in turn raise the blood pressure. Furthermore, the presence of flavonoids and triterpene possess significant vasodilatory effect that widens the blood vessels and ensures smooth blood flow throughout the body. In addition to this, antioxidants present in Jamun reduce the oxidative stress in kidneys and blood vessels and thus help in lowering high blood pressure. Besides this, Jamun is a good source of potassium that further helps in the treatment of hypertension. Thus, Jamun can be successfully made a part of DASH diet (DIETARY APPROACHES AGAINST HYPERTENSION).

Mouth Ulcers

The decoction is prepared using 10 grams Jamun Leaf powder and 800 ml water, which is simmered to reduce to 200 ml liquid. This decoction is used for gargling to treat mouth ulcers.
