The leaves, flowers, and berries of Crataegus plants make hawthorn. Many people take it to support heart health and already-normal blood pressure.
Capsules, tablets, and liquid extracts are the common forms. Consuming it with food helps absorption and lessens digestive issues. Standardized extracts exist, but the right dose varies from product to product.
Caution: Hawthorn can interact with heart medications and might lower blood pressure. Talk to a doctor before using it, especially if you take any heart or blood pressure drugs.
