Terminalia arjuna
Pronounced Arjuna = ar-JOO-nuh; Terminalia arjuna = ter-mih-NAY-lee-uh ar-JOO-nuh
Cool, dry, and astringent: it tones and strengthens a weak, over-worked, or racing heart, tightens lax vessels, and cools an inflamed cardiovascular terrain.
Insufficient reliable data; avoid. Ayurvedic tradition and modern references list arjuna as contraindicated or to be avoided in pregnancy owing to a lack of safety data. Source: Herbal Reality Arjuna monograph; WebMD consumer safety summary (insufficient evidence, avoid).
Insufficient reliable data; avoid medicinal use pending data. Sources conflict (some rate it possibly acceptable traditionally), but no adequate human lactation studies exist. Source: Herbal Reality Arjuna monograph; WebMD consumer safety summary.
No established modern pediatric dosing and no pediatric safety studies were located. Although Ayurveda has used arjuna for childhood cardiac conditions, reserve internal use in children for qualified practitioner guidance.
Astringent, cooling, and drying: may cause constipation, mild nausea, gastritis, headache, or (rarely) insomnia. High or prolonged doses may lower thyroid hormone levels and could aggravate or unmask hypothyroidism, so monitor in thyroid disease. Mild antiplatelet and blood-pressure-lowering activity warrants monitoring alongside relevant medication and discontinuation about 2 weeks before surgery. Serious cardiac disease must be managed by a physician; use arjuna as an adjunct only, not a replacement.
Avoid in pregnancy and lactation (safety not established; traditionally contraindicated in pregnancy). Use cautiously in hypothyroidism, in cold or deficient digestion with a tendency to constipation, and in bradycardia or hypotension. Coordinate with a physician when combined with cardiovascular, anticoagulant or antiplatelet, or thyroid medication. Not a substitute for prescribed cardiac therapy.
A large, widely cultivated and common riverine tree across the Indian subcontinent; not listed as threatened and not on the United Plant Savers list (which tracks North American natives). The main sustainability concern is bark harvesting: choose partial, regeneration-sparing bark collection or cultivated/plantation-sourced bark, as the tree renews its bark over time.
Not named in the canonical biblical texts. Native to the Indian subcontinent; the tree is named for the Mahabharata hero Arjuna, and its bark has served as a cardiac tonic in Ayurveda since antiquity, recorded in the Charaka Samhita and Sushruta Samhita and specifically advocated for heart ailments by Vagbhata (Ashtanga Hridaya, ~7th century CE). It carries an official monograph in the Ayurvedic Pharmacopoeia of India.
