Ginkgo Biloba (Maidenhair Tree) – Effects, Tablets, Price, Reviews

Originating from the remote regions of East Asia—particularly within China—the *Ginkgo biloba* L. tree stands as a botanical testament to resilience, with a documented history spanning nearly four millennia during which both its distinctive fan-shaped leaves and seeds were methodically employed in traditional healing practices. As a relic species that has endured geological epochs with minimal morphological alteration, this remarkable tree is characterized not only by its towering stature (reaching heights of up to 40 meters) but also by its thick, leathery foliage, which bears a striking resemblance to the ceremonial fans of Japan. Deeply embedded in the cultural heritage of the Far East—especially in China, Japan, and Korea—*Ginkgo biloba* embodies the principles of longevity and extraordinary environmental adaptability. While its therapeutic properties had been recognized for centuries, it was not until the mid-20th century, specifically during the 1950s, that the species gained substantial recognition within European clinical medicine, subsequently becoming a focal point of extensive scientific research.

A substantial body of experimental research and meta-analytical reviews confirms that the distinctive pharmacological properties of *Ginkgo biloba*—often referred to as a "living fossil"—are primarily attributable to two key classes of bioactive compounds: flavonoid glycosides (including quercetin and kaempferol) and specialized terpene lactones (notably ginkgolides A, B, C, and bilobalid). Standardized extracts derived from dried leaves, which contain a minimum of 24% flavonoid glycosides and 6% terpenoid lactones, serve as the foundation for therapeutically validated preparations widely employed in both European and North American clinical settings. Owing to its empirically demonstrated neuroprotective, antioxidant, and microcirculation-enhancing effects, *Ginkgo biloba* extract is effectively utilized in the management of age-related cognitive impairments (including mild cognitive impairment and vascular dementia), as well as in the treatment of cerebrovascular insufficiency and peripheral circulatory disorders. Within the pharmaceutical marketplace, the extract is available in diverse formulations—such as standardized tinctures (*Tinctura Ginkgo bilobae*), sustained-release capsules, film-coated tablets, oral drops, and granules—thereby facilitating personalized dosage regimens tailored to individual patient requirements [1, 2, 4].

The standardized dry extract derived from the leaves of *Ginkgo biloba* L. (designated as EGb 761) serves as the primary active constituent in a pharmaceutical formulation available in two convenient oral delivery systems: enteric-coated tablets with modified-release properties and liquid drops intended for sublingual administration. Within the contemporary landscape of prescription and over-the-counter medicinal products based on this botanical extract, a multitude of clinically validated preparations have gained prominence, including branded formulations such as **Seredrin®**, **Bilobil®**, **Tanakan®**, **Tebokan®**, **Keveri®**, **Craton®**, **Ginkgobil®**, **Gincgosan®**, **Teboforan®**, **Rokan®**, **Genoforce®**, **Tebonin®**, and **Ginkgofar®** [2]. Clinicians specializing in geriatric and neurological care frequently prescribe these agents for elderly patients presenting with mild-to-moderate dementia-related symptoms, which may manifest as recurrent vascular vertigo episodes, persistent tinnitus, progressive impairments in both short- and long-term memory retention, emotional lability with predisposition to anxiety disorders, and diminished spatiotemporal orientation capacities. The therapeutic mechanism operates through a multifactorial influence on the circulatory system: bioactive constituents within the extract—primarily ginkgolide flavonoids and terpene lactones—enhance hemorheological parameters, augment capillary fragility resistance, and optimize cerebral microvascular perfusion, thereby potentially mitigating the risk of ischemic stroke events. In the context of dietary supplementation, these preparations are additionally employed as cognitive enhancers, facilitating improvements in memory encoding, information processing efficiency, and sustained attention during complex intellectual tasks.

The contemporary pharmaceutical and dietary supplement market provides a diverse selection of products based on standardized *Ginkgo biloba* leaf extract, with pricing varying significantly according to active ingredient concentration, tablet quantity per package, and manufacturer reputation. For instance, therapeutic-dose preparations containing between 120 and 240 milligrams of extract per tablet—such as *Bilobil intense*—are priced in the range of PLN 24–49 for a 60-tablet supply. Another widely recognized herbal product, *Tebokan*, produced by the German company *Dr. Willmar Schwabe GmbH & Co. KG*, retails at approximately PLN 48 for 50 tablets (each containing 40 mg of standardized ginkgo extract). The same manufacturer also offers higher-potency versions, with 120 mg of extract per tablet, priced at around PLN 47 for a 30-tablet package. As per the manufacturer’s guidelines, this supplement is particularly recommended for individuals experiencing mild cognitive impairments, including memory deficits, reduced concentration, depressive symptoms, or recurrent dizziness.

A substantial body of scientific research corroborates the therapeutic benefits of Ginkgo biloba extracts, particularly in addressing the early stages of Alzheimer’s disease and age-related dementia symptoms. Owing to its rich composition of bioactive compounds, this botanical ingredient is also widely utilized in cosmetics—formulated into creams for sensitive and couperose-prone skin, toners, gels, shampoos, and hair conditioners. However, it is crucial to note that Ginkgo biloba leaves contain ginkgolic acids, which are associated with allergenic potential. Consequently, standardized extracts must not exceed a concentration of 0.0005% of these acids [3]. Clinical trials indicate that Ginkgo biloba preparations carry a low risk of adverse effects, most commonly including headaches, allergic reactions, and mild gastrointestinal disturbances (nausea, vomiting, diarrhea). A key clinical consideration is its anticoagulant activity, necessitating caution in patients taking blood-thinning medications (e.g., heparin, warfarin, aspirin) [1]. Undoubtedly, Ginkgo biloba represents a valuable botanical resource with well-documented antioxidant and anti-inflammatory properties, supporting memory retention, alleviating tinnitus, and enhancing cognitive function in elderly individuals with dementia. Furthermore, its cardioprotective effects may contribute to the prevention and treatment of circulatory disorders [1].
