Hawthorn
Crataegus spp. — also: Mayflower, Thornapple
Some human trials suggest adjunctive benefit in mild heart failure — but this is a serious condition that needs a physician, not self-treatment.
A revered European 'heart' herb and a Chinese digestive; long used as a cardiovascular tonic.
Studied as adjunct support in mild heart failure (symptoms, exercise tolerance) and for blood pressure.
Flavonoids and oligomeric procyanidins may have mild vasodilatory and antioxidant cardiac effects.
- Possible adjunct support in mild heart failure/BP
Several trials as add-on in mild heart failure; not a standalone therapy.
- Serious condition involved
- Self-treatment is risky
- Strong cardiac-drug interactions
- Masking real heart disease
- Anyone with heart disease or on heart/BP meds without a doctor
Generally well tolerated; dizziness, GI upset; the concern is masking serious cardiac disease.
May potentiate heart, blood-pressure, and nitrate medications (digoxin, beta-blockers, etc.) — HIGH interaction caution.
Anyone with heart disease must involve a cardiologist; limited pregnancy data.
Common hedgerow tree; berries, leaves, and flowers are used.
Real cardiac signal in studies — which is exactly why it belongs in a cardiologist's plan, not a solo experiment.
