Hawthorn

Crataegus monogyna

also known as May tree, Whitethorn, Crataegus

Moderate (mild heart failure)

A small tree from the rose family whose berries, leaves, and flowers have been a European heart tonic for centuries. Modern research backs the tradition — hawthorn extract has real, well-studied benefit in early-stage heart failure, and works by supporting the heart muscle itself rather than just masking symptoms.

  • Supports the heart muscle in early-stage heart failure — improves exercise tolerance and reduces symptoms like shortness of breath and fatigue
  • Mildly lowers blood pressure
  • Antioxidant action that protects heart tissue
  • Improves blood flow to the heart by gently dilating coronary arteries
  • Long traditional European use as a gentle heart tonic, dating back to the Middle Ages

Active in Proanthocyanidins (OPCs), Vitexin, Flavonoids, Triterpenes.

Heart conditions need medical management — hawthorn complements but does not replace standard heart failure treatment
Use caution with digoxin and other heart medications — hawthorn can amplify their effects
Use caution with blood pressure medications — additive lowering
Stop two weeks before surgery
Skip during pregnancy and nursing — can stimulate the uterus
Anyone with a known heart condition should start hawthorn only with provider awareness
