Hawthorn Powder
Also known as: Crataegus, Crataegus monogyna, Crataegus laevigata, Hawthorn extract, Hawthorn Powder
Overview
Hawthorn is an herbal extract derived from the leaves, flowers, and berries of the *Crataegus* species, primarily *Crataegus monogyna* and *Crataegus laevigata*. It is indigenous to Europe, Asia, and North America, and has a long history of use in traditional medicine to support heart health, particularly in the management of conditions like hypertension and heart failure. Hawthorn is rich in flavonoids and oligomeric procyanidins, contributing potent antioxidant properties. Current research supports its efficacy, particularly for patients with chronic heart failure, where multiple clinical trials and meta-analyses reveal significant benefits. While the evidence regarding its role in hypertension is less conclusive, it indicates moderate maturity in research, reflecting robust outcomes in heart failure treatments.
Benefits
Hawthorn extract has been shown to enhance exercise tolerance and lessen cardiac workload in those with chronic heart failure (NYHA classes I-III). Clinical studies reveal significant improvements in maximal workload, averaging an increase of 7 Watts, along with relief from symptoms such as dyspnea and fatigue, especially in patients with mild to moderate heart failure. Furthermore, hawthorn may assist in blood pressure regulation, potentially enhancing effects when combined with other herbs; however, more research is needed in this area. Notable benefits from hawthorn are realized within weeks to months, indicating clinically relevant outcomes for patients.
How it works
Hawthorn functions primarily by enhancing cardiac output and promoting vasodilation, which reduces peripheral resistance. Active compounds like flavonoids and oligomeric procyanidins play a key role in improving endothelial function and stimulating nitric oxide synthesis. This biological activity supports a healthier cardiovascular system, contributing to lower blood pressure and more regulated heart rate.
Side effects
Hawthorn is typically considered safe when used as directed. Common side effects observed (>5%) include nausea and dizziness, while less frequent side effects (1-5%) can involve fatigue, sweating, palpitations, and headaches. Rare effects (<1%) include dyspnea, sleeplessness, agitation, and epistaxis. Caution is advised, as hawthorn may interact with certain medications, particularly those impacting heart conditions, such as digoxin and beta-blockers. Due to these potential interactions and its effects on cardiac function, individuals with severe cardiac conditions and pregnant or breastfeeding women should consult healthcare providers before using hawthorn.
Dosage
The standard initial dosage of hawthorn is around 160 mg per day, with optimal dosages generally ranging from 600 to 1,800 mg daily, divided into two or three doses. It is recommended not to exceed 1,800 mg daily, as firm safety thresholds are not established. To promote better absorption and minimize gastrointestinal discomfort, it's advisable to consume hawthorn with meals. Standardized extracts are preferred to ensure consistent levels of active compounds for effective results.
