Arjuna bark (Terminalia arjuna)

Tier 3 — weak evidence · Heart failure · Angina · Cholesterol

An Ayurvedic heart tonic with growing clinical evidence. Multiple Indian trials show it significantly improves ejection fraction in heart failure, reduces angina frequency, and modestly lowers cholesterol. Contains arjunolic acid, which strengthens heart muscle contractions. Used alongside conventional heart medications, not as a replacement. May interact with cardiac drugs and blood thinners.

Dose: 500 mg bark extract × 2 daily; use under medical supervision alongside cardiac medications
