For centuries, it has been widely used as a natural remedy to strengthen the heart, improve blood circulation, and maintain overall cardiovascular balance.

Top 5 Arjuna Benefits for Heart Health

Here are 5 research-backed benefits of arjuna for heart health:

1. Promotes Healthy Heart Function

Arjuna has been valued for its ability to support the heart’s normal functions. The bark contains natural compounds like flavonoids and tannins that help strengthen heart muscles, improve blood flow, and support a steady heart rhythm. 

Because of these properties, arjuna is often used to maintain overall cardiovascular wellness. It helps the heart work efficiently and supports long-term heart vitality.

2. Controls Blood Pressure

Research shows that arjuna plays a supportive role in maintaining healthy blood pressure levels. Its above-mentioned natural compounds help relax and strengthen blood vessels, allowing blood to flow more smoothly throughout the body. This reduces strain on the heart and supports stable pressure levels.²

Arjuna also promotes healthier circulation and may help the body respond better to physical and emotional stress, both of which can influence blood pressure.

3. Fights Inflammation

Inflammation inside the body can damage blood vessels and strain the heart. Arjuna’s natural plant compounds help in reducing internal inflammation. 

By lowering inflammatory activity, arjuna supports healthier arteries and improves overall circulatory wellness. This creates a protective effect for the heart and blood vessels.

4. Manages Cholesterol Levels

High cholesterol is one of the major contributors to heart disease. Arjuna has shown potential in helping lower LDL (bad cholesterol) and triglycerides (a type of fat in the body that stores excess energy from the food) while supporting higher HDL (good cholesterol).²

Better cholesterol balance contributes to cleaner arteries and smoother blood circulation. Over time, this helps reduce the risk of blockages and supports better heart performance.

Terminalia arjuna – flowers and seeds

Climate and soil

• The plant naturally occurs in sub- tropical and tropical moist regions of the country.
• The tree prefers alluvial loamy or black cotton soils, which are loose, moist, fertile, and have good drainage and water holding capacity.
• River bank soils, streams, and ravines are its natural habitat.
• The plant also survives in open sunny and low rainfall areas.

Planting material

• Propagation gives best result when seeds are used. The seeds can be collected in early summer from trees that are more than six-year-old.
• Ripe fruits are collected in March either by lopping the branches or from the ground previously swept clean.
• The seeds are viable for at least one year when stored in sealed tins.

Agro-technique

Nursery technique

Raising propagules

• Seeds are sown in nursery beds in early summer, usually just after collection.
• Germination commences in 8–12 days, and is completed in seven to eight weeks. Germinated seeds may be transplanted in polybags with clay, manure, and sand in equal ratio.
• Alternatively, the pretreated fruits are directly put in polythene bags in April, with half of the fruit above the soil.
• Pre-germinated seeds are preferred to save time and ensure uniform germination.
• The seedlings are sensitive to drought during the germination stage as well as during the growth stage.

Propagule rate and pretreatment

• The number of fruits per kg varies from about 200 to 1200, depending on the size of the fruits.
• Hence, about 4–10 kg of seeds may be required for raising 1 hectare of plantation at a spacing of 6 m × 6 m.
• The seeds should be pretreated by soaking them in cool water for 48 hours.
• Alternatively, the seeds may be soaked in boiling water and allowed to cool.
• The seeds should remain soaked for 24 hours.
• The germination rate of pretreated seeds is up to 90%, while that of untreated seeds is 50%–60%.

Terminalia arjuna – infestation by insect

Planting in the field

Land preparation and fertilizer application

• Preparatory tillage is done in the field, which should be levelled, and pits of size 45 cm × 45 cm × 45 cm are dug at a spacing of 6 m × 6 m.
• About 10 kg FYM (farmyard manure) and NPK (nitrogen, phosphorus, and potassium) @ 75:50:30 g are added per pit and thoroughly mixed with soil as basal dose.

Transplanting and optimum spacing

• About 10-month-old saplings are transplanted in the field in pits in July–August at a spacing of 6 m × 6 m.
• In all, about 280–300 saplings are required per hectare.

Intercropping system

• The crop can be grown as a sole plantation in early growth stage or as a border of other crops.
• Climbers like Tinospora cordifolia (Giloy), Marsdenia tenacissima (Moorva), Operculina turpethum (Trivrit), Opercullina petaloidea (Nishoth), and Celastrus paniculata (Malkangni) may be planted beneath the fully grown tree that serves as host for these climbers.

Interculture and maintenance practices

• About 10 kg FYM + 75:50:30 g NPK per plant are applied as a basal dose at the time of transplanting.
• Further top dressing is given with 50 g nitrogen per tree after three months.
• Field should be kept weed-free.

Irrigation practices

• Irrigation is recommended at 15-day intervals in the summer season for young plantations.
• Irrigation is generally not done during the winter season in the peninsular region.

Disease and pest control

• Aphids (Aphis sp.) attack tender leaves and form galls on it.
• Spraying of biopesticides like Azadirachtin controls this pest.
