Terminalia arjuna (family Combretaceae), commonly referred to as Arjuna, is one of the most prominent cardiovascular tonics in traditional Ayurvedic pharmacology (Hridya)[1]. Used for over a millennium to treat chest pain, heart failure, hypertension, and dyslipidemia, modern clinical and pharmacological research has validated its multi-target mechanisms[2]. The therapeutic profile of T. arjuna stem bark stems from a complex matrix of oleanane triterpenoids, triterpenoid glycosides, flavonoids, and hydrolyzable tannins that collectively confer anti-ischemic, anti-atherosclerotic, antihypertensive, and antioxidant cardioprotection[3].
Therapeutic Use
Obesity (medoroga), wound management (vrana), heart diseases (hridroga), loss fof strength due to injury (kshatakshaya), obstinate urinary disorders including diabetes mellitus (prameha), thirst (trishna), melasma (vyanga)[4]

Major Phytochemical Constituents
The pharmacological activities of Terminalia arjuna bark are attributed to four primary bioactive classes[2]:
| Phytochemical Class | Key Active Constituents | Primary Pharmacological Roles |
|---|---|---|
| Oleanane Triterpenoids | Arjunolic acid, Arjunic acid, Arjungenin, Terminic acid | Cardioprotective, anti-platelet, anti-apoptotic, and direct free-radical scavenging[8]. |
| Triterpenoid Glycosides | Arjunetin, Arjunosides I–IV, Arjunglucosides I & II | Inotropic, chronotropic, and cardiac membrane-stabilizing activities. |
| Flavonoids & Phenolics | Arjunone, Arjunolone, Baicalein, Luteolin, Quercetin | Endothelial nitric oxide stimulation, vasodilation, and inhibition of LDL oxidation. |
| Hydrolyzable Tannins | Punicalagin, Punicallin, Casuarinin, Terflavin C | Vascular astringency, anti-inflammatory, and extracellular matrix protection. |
Pharmacological Mechanisms & Scientific Evidence
Cardioprotective & Anti-Ischemic Actions
T. arjuna extracts preserve myocardial structural integrity during ischemic events and reperfusion injury[1]:
- Endogenous Antioxidant Preservation: Prevents the depletion of key intracellular antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)[3].
- Anti-Apoptotic Regulation: Downregulates pro-apoptotic markers (Bax, caspase-3) while upregulating anti-apoptotic proteins (Bcl-2) and heat shock proteins (HSP-70) in ischemic cardiomyocytes[2].
A double-blind, randomized, placebo-controlled crossover study evaluated 58 patients with chronic stable angina (NYHA Class II–III). Administration of 500 mg of T. arjuna bark extract every 8 hours significantly reduced anginal frequency and nitrate consumption, accompanied by objective improvements in treadmill exercise duration and reduced peak ST-segment depression compared to placebo[9]. Furthermore, clinical evaluations in congestive heart failure and ischemic heart disease demonstrate improved left ventricular ejection fraction[10].
Vascular Tone & Anti-Hypertensive Efficacy
- Endothelial Nitric Oxide Activation: Flavonoid and glycoside fractions stimulate endothelial nitric oxide synthase (eNOS), increasing vascular NO availability and inducing endothelium-dependent vasodilation[2].
- Inotropic & Chronotropic Balance: Demonstrates positive inotropic (enhancing force of contraction) and mild negative chronotropic (regulating pulse rate) effects without increasing myocardial oxygen demand[1].
Anti-Platelet & Anti-Atherosclerotic Effects
- Thrombin-Induced Inhibition: The isolated triterpenoid arjunolic acid inhibits thrombin-induced platelet aggregation with an <math>IC_{50}</math> of 0.048 mM—exhibiting greater potency than aspirin (<math>IC_{50} = 0.088\text{ mM}</math>)[8][3].
- Lipid Modulation & Foam Cell Suppression: Reduces circulating total cholesterol, low-density lipoprotein (LDL), and triglycerides while raising high-density lipoprotein (HDL) via upregulation of PPAR-γ pathways and suppression of oxidative LDL modification[1].
Posology & Preparations
| Traditional / Modern Preparation | Standardized Dosage | Primary Clinical Applications |
|---|---|---|
| Arjuna Churna (Stem Bark Powder) | 3–6 g daily (with milk or warm water) | General cardiotonic, hyperlipidemia, mild hypertension. |
| Arjuna Kwath (Decoction) | 50–100 ml daily (1:4 reduced decoction) | Angina pectoris, heart failure support, fluid overload. |
| Arjunarishta (Hydro-alcoholic Ferment) | 15–30 ml twice daily after meals | Post-myocardial recovery, palpitations, cardiac fatigue. |
| Standardized Dry Extract (Capsule/Tablet) | 250–500 mg twice or thrice daily | Ischemic heart disease, coronary artery disease prophylaxis. |
Safety, Toxicology & Contraindications
- Toxicological Profile: Preclinical safety evaluations demonstrate high oral safety thresholds (<math>LD_{50} > 2000\text{ mg/kg}</math> in rodent models)[2]. Clinical studies confirm excellent tolerability across long-term administration[9].
- Adverse Reactions: Mild, transient gastrointestinal effects (such as mild constipation or dyspepsia) may occur due to the high tannin concentration.
- Precautions & Interactions:
- Anticoagulants & Antiplatelets: Given arjunolic acid's inhibitory effect on thrombin-induced aggregation, monitor coagulation metrics when co-prescribed with agents like Warfarin, Aspirin, or Clopidogrel[8].
- Antihypertensives: Potential additive hypotensive effects; routine blood pressure monitoring is advised when integrated into existing antihypertensive regimens[1].
