Hawthorn (Two- and Single-Necked) – Effects and Contraindications

Hawthorn, a genus within the *Rosaceae* family, occupies a distinguished position in European flora due to its ecological adaptability and medicinal significance. The botanical nomenclature derives from the Greek term *"kratos,"* denoting hardness and resilience—qualities embodied by the plant’s dense, durable wood. This deciduous shrub or small tree proliferates across the continent, enhancing the visual and functional diversity of deciduous forests, roadsides, municipal parks, and residential gardens. While over two hundred hawthorn species exist globally, the European landscape is predominantly populated by the common hawthorn (*Crataegus monogyna*), the midland hawthorn (*Crataegus laevigata*), and their hybrid variant, *Crataegus × media*. For centuries, the berries and inflorescences of these species have been integral to traditional medicine, particularly in cardiovascular support therapies. Pharmacies and herbalists offer both dried botanical materials (flowers and fruits) for infusions and standardized leaf extracts of *Crataegus oxyacantha*. The berries are harvested in autumn, typically from late September through October, though they frequently persist on branches until the first frost. Beyond their therapeutic use, they serve as a versatile culinary ingredient in jams, jellies, fruit preserves, herbal teas, fermented beverages, cordials, and confectionery, prized for their subtly tart flavor profile.

Contemporary scientific evidence confirms that both the fruits and flowers of hawthorn (*Crataegus* spp.) constitute a rich reservoir of bioactive phytochemical compounds, prominently featuring flavonoids, procyanidins, and phenolic acid derivatives—substances with well-documented antioxidant and cardioprotective properties. Within traditional healing systems, including European folk medicine, hawthorn-based preparations such as hydroalcoholic extracts, infusions, and decoctions have been extensively employed as adjunctive therapy for cardiovascular disorders (e.g., coronary insufficiency, arrhythmias, arterial hypertension), as well as for alleviating gastrointestinal complaints (e.g., functional diarrhea, dyspepsia) and metabolic dysfunctions. *In vitro* and *in vivo* investigations demonstrate that *Crataegus* extracts exert multifaceted pharmacodynamic effects: they enhance myocardial perfusion via coronary vasodilation, modulate the activity of lipid-metabolizing enzymes (resulting in hypocholesterolemic outcomes), and exhibit neuroprotective and anxiolytic attributes mediated through interactions with GABAergic receptors. Additionally, the high ascorbic acid content in hawthorn flowers renders the plant a valuable adjunct in the prevention of seasonal infections. This material further includes a practical recipe for homemade hawthorn tincture, complete with dosage guidelines and flavor-modification suggestions.

Homemade preparations derived from the fruits and flowers of hawthorn (*Crataegus* spp.) are widely regarded as safe and rarely associated with adverse effects. Current scientific evidence supports the notion that even prolonged use of these remedies does not lead to significant side effects. However, owing to the plant’s hypotensive properties, individuals with chronically low blood pressure should exercise heightened caution and seek guidance from a healthcare professional before incorporation. Hawthorn, abundant in polyphenols, flavonoids, and procyanidins, has been valued for centuries for its cardioprotective and vasoregulatory benefits. As early as antiquity, the eminent Greek botanist and physician Dioscorides documented its medicinal applications. Contemporary phytotherapy, revisiting these age-old remedies, increasingly advocates for supplementation with hawthorn extracts—whether as infusions of dried berries or traditionally prepared tinctures—following time-honored formulations aimed at enhancing overall well-being.
