Hawthorn (Crataegus monogyna) contains oligomeric procyanidins and flavonoids that demonstrate antioxidant activity through superoxide anion scavenging and metal chelation. This European herb has been traditionally used for cardiovascular support and digestive health, though clinical evidence remains limited.
Hawthorn (Crataegus monogyna Jacq.) is a flowering shrub native to Europe, Western Asia, and North Africa, with fruits, leaves, and flowers used medicinally. The plant material is typically extracted using aqueous or ethanol solvents to produce concentrated extracts containing high concentrations of flavonoids and phenolic acids.
The provided research contains only in vitro antioxidant assays and phytochemical analyses, with no human clinical trials, randomized controlled trials, or meta-analyses included. No PubMed PMIDs were provided in the research dossier.
No clinically studied dosage ranges for human use were provided in the research. The studies only reference laboratory concentrations of 100 μg/mL for in vitro testing, which cannot be translated to clinical dosing. Consult a healthcare provider before starting any new supplement.
Hawthorn berries (Crataegus monogyna) contain a well-characterized profile of bioactive compounds, particularly polyphenols, with moderate macronutrient content. Macronutrients per 100g fresh weight: carbohydrates 11-17g (primarily fructose, glucose, sucrose), dietary fiber 3-5g (pectin-rich, supporting digestive transit), protein 0.4-0.9g, fat <0.5g, water content ~75-80%. Key micronutrients include vitamin C (approximately 35-90mg/100g fresh berries, though variable by ripeness and origin), vitamin B-complex traces (B1, B2, B6), potassium (approximately 250-430mg/100g), calcium (approximately 40-60mg/100g), magnesium (approximately 14-20mg/100g), phosphorus (approximately 20-35mg/100g), and iron (approximately 0.5-1.2mg/100g). Primary bioactive compounds: oligomeric proanthocyanidins (OPCs) at 1-3% dry weight (primarily epicatechin and catechin-based dimers and trimers, concentrated in leaves, flowers, and bark more than berries), vitexin-2-O-rhamnoside (a C-glycosylflavone, 0.1-0.9% dry weight in leaf/flower extracts), hyperoside (quercetin-3-galactoside, approximately 0.2-1.5% dry weight), rutin, chlorogenic acid (approximately 0.5-2.0mg/g dry weight), and ursolic acid (a pentacyclic triterpene, approximately 0.3-0.6% in berry skin). Anthocyanins (cyanidin-3-galactoside, cyanidin-3-glucoside) contribute 1-5mg/g to the reddish pigmentation of ripe berries. Bioavailability notes: OPCs and flavonoids undergo significant first-pass metabolism; vitexin glycosides show moderate intestinal absorption (~20-30% in animal models); polyphenol absorption is enhanced by the food matrix fiber (slower gastric transit) but may be reduced by co-ingestion with proteins. Standardized herbal extracts (WS 1442 and LI 132 pharmaceutical grades) are typically standardized to 18.75% OPCs or 2.2% flavonoids, providing more consistent bioactive delivery than raw berry consumption.
Hawthorn's oligomeric procyanidins and flavonoids like vitexin and hyperoside scavenge superoxide anions and chelate metal ions, reducing oxidative stress. These compounds may also modulate nitric oxide pathways and inhibit angiotensin-converting enzyme (ACE), potentially supporting cardiovascular function through multiple antioxidant mechanisms.
Current evidence for hawthorn is primarily limited to in vitro studies demonstrating antioxidant activity through superoxide scavenging and metal chelation. No clinical trials have been provided to support the traditional cardiovascular or digestive health claims. Most evidence remains at the preclinical level, with human studies needed to validate traditional uses and establish effective dosages.
Hawthorn is generally well-tolerated but may interact with cardiovascular medications including digoxin, beta-blockers, and calcium channel blockers due to its potential cardioactive effects. Common side effects may include dizziness, nausea, and digestive upset at higher doses. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals taking heart medications should consult healthcare providers before use.
