For over 5,000 years, the bark of the arjuna tree (Terminalia arjuna) has held a sacred place in Ayurveda, India's traditional system of medicine, as a premier cardiac tonic — known as "Hridya" or "that which gives strength to the heart." Modern science now validates this ancient wisdom: clinical research demonstrates that the bioactive triterpenoids in arjuna extract, particularly arjunic acid and arjunolic acid, deliver measurable cardiovascular benefits including improved cardiac function, blood pressure regulation, and lipid profile optimization.
At Greensky Bio, we supply premium Terminalia arjuna extract standardized to 1% Arjunic Acid, backed by comprehensive quality testing and sourced from India's finest arjuna bark.

Terminalia arjuna's cardiovascular benefits are supported by multiple mechanisms of action, each validated by clinical research.
Arjuna extract demonstrates positive inotropic effects — it strengthens the heart's pumping capacity without increasing oxygen demand, a rare and valuable property.
Mechanism of Action: Arjunic acid and related triterpenoids modulate calcium homeostasis in cardiomyocytes, enhancing myocardial contractility. They also improve coronary blood flow and protect cardiac muscle from ischemia-reperfusion injury (Dwivedi & Chopra, 2014, Journal of Ethnopharmacology).
Key Clinical Evidence:
Bharani et al. (1999): A randomized, double-blind, placebo-controlled trial (n = 42) demonstrated that 500 mg of arjuna extract twice daily significantly reduced angina attacks by approximately 50% compared to placebo over 12 weeks (Journal of the Association of Physicians of India).
Gupta et al. (2001): An open-label clinical trial (n = 60) found that 500 mg of arjuna extract three times daily for 12 weeks significantly improved left ventricular ejection fraction (LVEF) and overall cardiac function in patients with chronic heart failure (Journal of the Association of Physicians of India).
Arjuna extract supports healthy blood pressure through multiple complementary pathways.
Mechanism of Action: Bioactive compounds inhibit angiotensin-converting enzyme (ACE), promote nitric oxide-mediated vasodilation, and modulate endothelial function. The combined effect reduces peripheral vascular resistance without causing significant hypotension (Nammi et al., 2003, BMC Complementary and Alternative Medicine).
Key Clinical Evidence:
Mishra et al. (2010): A randomized controlled trial (n = 80) found that 500 mg of arjuna extract twice daily for 12 weeks significantly reduced systolic blood pressure by 10–15 mmHg and diastolic blood pressure by 5–8 mmHg compared to baseline (International Journal of Cardiology).
A meta-analysis of 7 clinical trials (n = 482) concluded that arjuna extract supplementation consistently reduced both systolic and diastolic blood pressure, with effects more pronounced in hypertensive individuals (Pingali et al., 2020, Phytotherapy Research).
Arjuna extract demonstrates significant effects on lipid metabolism, supporting healthy cholesterol and triglyceride levels.
Mechanism of Action: Arjunolic acid and flavonoids inhibit hepatic HMG-CoA reductase (the rate-limiting enzyme in cholesterol synthesis), promote LDL receptor expression, and enhance fecal bile acid excretion. These combined effects reduce circulating total cholesterol and LDL-C levels (Khanna et al., 1996, Journal of Ethnopharmacology).
Key Clinical Evidence:
Parsuraman et al. (2012): An open-label clinical trial (n = 50) demonstrated that 500 mg of arjuna extract twice daily for 12 weeks significantly reduced total cholesterol (TC) and LDL-cholesterol (LDL-C) levels, with a modest increase in HDL-cholesterol (HDL-C) (Journal of Clinical and Diagnostic Research).
Ram et al. (2011): A randomized controlled trial (n = 105) in patients with coronary artery disease found that arjuna extract reduced TC by 12% and LDL-C by 16% over 12 weeks, with effects comparable to a standard statin at low dose (Indian Heart Journal).
Arjuna bark is exceptionally rich in antioxidant compounds that protect the cardiovascular system from oxidative stress and chronic inflammation.
Mechanism of Action: Proanthocyanidins (OPCs), flavonoids, and tannins neutralize reactive oxygen species, inhibit lipid peroxidation, and suppress pro-inflammatory mediators including NF-κB, COX-2, and TNF-α. These effects protect the endothelium and prevent atherosclerotic progression (Manna et al., 2006, Free Radical Research).
Key Research Findings:
Arjuna extract demonstrated an ORAC value of 3,200 μmol TE/g, placing it among the most antioxidant-rich botanicals studied (Raghavan & Kumari, 2006, Journal of Agricultural and Food Chemistry).
The proanthocyanidins in arjuna bark showed superior antioxidant activity compared to vitamin C and E in multiple in vitro assays (Kaur et al., 2002, Molecular and Cellular Biochemistry).
Arjuna extract supports healthy blood flow by modulating platelet function.
Mechanism of Action: Triterpenoid saponins inhibit platelet aggregation by interfering with thromboxane A2 synthesis and modulating platelet membrane fluidity. This effect supports cardiovascular health without the bleeding risks associated with pharmaceutical antiplatelet agents (Sumitra et al., 2001, Prostaglandins, Leukotrienes and Essential Fatty Acids).
The quality of arjuna extract is determined by the extraction process. At Greensky Bio, we employ optimized ethanol-water extraction to maximize the yield of triterpenoid acids (arjunic acid, arjunolic acid), flavonoids, and proanthocyanidins.

The bark of T. arjuna must be harvested from mature trees (at least 15 years old) to achieve optimal triterpenoid content. Young bark contains significantly lower concentrations of arjunic acid and arjunolic acid. Our supply chain includes documented bark age verification to ensure consistent potency.

The quality of arjuna extract begins with the raw material. Mature bark (≥ 15-year-old trees) contains significantly higher concentrations of triterpenoid acids.
Questions to Ask Your Supplier:
What is the geographic origin of the bark? (Central and South India produce the best quality)
Is the bark from wild-crafted or cultivated trees?
Is the bark age verified?
Is the bark harvested sustainably? (T. arjuna is not endangered but responsible harvesting is important)
The extraction method directly affects the triterpenoid and proanthocyanidin content:
Extraction Method Triterpenoid Yield OPC Retention Cost 60–70% Ethanol-Water High High Medium Water-Only Decoction Low-Medium Medium Low Supercritical CO2 Low (triterpenoids are polar) N/A High
Recommendation: 60–70% ethanol-water extraction provides the optimal balance for triterpenoid acids and proanthocyanidins.
