1. Hawthorn (Crataegus spp.)

Detailed Overview:
Hawthorn is often called the “heart herb” because of its profound ability to support cardiovascular health. It has been used for centuries in both Western herbalism and Traditional Chinese Medicine to improve heart function, regulate blood pressure, and enhance circulation. Hawthorn works gently, making it ideal for long-term use.

Chemical Constituents and Actions:

• Flavonoids (quercetin, rutin): These powerful antioxidants protect against free radical damage, reducing oxidative stress on the heart and blood vessels.
• Proanthocyanidins: Improve the elasticity and strength of blood vessel walls, reducing risks of plaque buildup and atherosclerosis.
• Triterpenoids: Support heart muscle function and have anti-inflammatory effects.
• Oligomeric procyanidins (OPCs): Promote blood flow and reduce arterial stiffness.

Tissue States and Mechanisms:
Hawthorn is particularly useful for addressing tension (wind) and cool, dry conditions in the cardiovascular system. It strengthens the heart muscle (myocardium) and enhances coronary artery blood flow, improving oxygen delivery to the heart. It is both a circulatory and cardiac tonic, addressing underlying stagnation in blood flow.

Therapeutic Benefits:

• Improves symptoms of congestive heart failure (CHF), including fatigue and shortness of breath.
• Regulates blood pressure by relaxing and dilating blood vessels.
• Reduces anxiety-related palpitations.
• Supports recovery after heart surgery or heart attacks.

Preparation and Dosage:

• Tea: Brew 1 tablespoon of dried berries in 8 ounces of water for 15 minutes, 2-3 times per day.
• Tincture: Take 1–2 dropperfuls, 2–3 times daily.
• Capsules: 500 mg, up to twice daily.

Contraindications:
Avoid combining with prescription heart medications without professional supervision, as hawthorn may enhance their effects.

The Science

Hawthorn has been extensively studied for its cardiotonic properties. A systematic review published in the American Journal of Medicine concluded that hawthorn improves symptoms of chronic heart failure (CHF), such as fatigue and shortness of breath, while also enhancing exercise tolerance. The study attributes these benefits to hawthorn’s high flavonoid content, which strengthens blood vessels and improves circulation.
