]( https://www.societeapothecary.com/s/search?q=ginkgo ) Ginkgo Leaf: Materia Medica Ancient and resilient, the Ginkgo tree is a living fossil—unchanged for over 200 million years. Its fan-shaped leaves, once food for dinosaurs, now serve as powerful medicine for the modern mind and circulation. Ginkgo stands as a bridge between memory and presence, tradition and renewal. “Ginkgo carries the wisdom of time—strengthening memory, circulation, and spirit with every golden leaf.” MATERIA MEDICA Latin Binomial: Ginkgo biloba Common Name(s): Ginkgo, Maidenhair Tree TCM Name: Bai Guo Ye (白果叶) Ayurvedic Name: Not classically used but sometimes adopted in modern formulations Family: Ginkgoaceae Physical Description of the Plant: A tall, deciduous tree with distinct fan-shaped, bilobed leaves that turn brilliant yellow in autumn. Ginkgo trees are dioecious (separate male and female trees). Female trees bear malodorous fruits, while the leaf is used medicinally. Habitat: Native to China; now cultivated worldwide in temperate regions. Highly tolerant of urban pollution and soil variation. Harvest and Collection: Leaves are harvested in summer to early fall before they begin to yellow. Dried quickly in shade to preserve phytochemicals. Parts of the Plant Used: Leaves (the seeds or “nuts” are used in TCM with caution but not generally recommended due to toxicity) Qualities: Bitter, slightly astringent Energetics: Neutral to slightly cooling; drying, stimulating to circulation Chemical Constituents: Flavonoid glycosides (quercetin, kaempferol) Terpenoids (ginkgolides, bilobalide) Organic acids Proanthocyanidins Antioxidants Actions: Nootropic Vasodilator (especially microcirculation) Antioxidant Neuroprotective Antiplatelet (mild) Tonic for capillaries and veins Anti-inflammatory (mild) Anti-vertigo Indications: Memory loss, cognitive decline, early-stage Alzheimer’s Tinnitus and vertigo (vascular-related) Raynaud’s syndrome and poor extremity circulation Eye health (macular degeneration, glaucoma adjunct) Intermittent claudication (leg cramping from poor blood flow) Brain fog and mental fatigue Recovery after stroke or brain injury (adjunctive use) Diagnostic Picture: Ginkgo is suited for individuals with sluggish circulation to the brain or extremities—cold hands and feet, slow memory recall, dizziness, or vascular tension. Best for the aging, mentally fatigued, or forgetful. Contraindications/Cautions: May increase bleeding risk; avoid with blood thinners or before surgery Rare side effects: headache, digestive upset, dizziness Avoid use of seeds unless under trained guidance (toxic in high doses) Drug Interactions: Anticoagulants (warfarin, aspirin, etc.) Antiplatelet drugs Seizure medications (high doses may reduce seizure threshold) Monitor closely with diabetes medications (can slightly alter glucose regulation) Dosage: Tincture: 1–2 mL up to 3x daily Capsules/Extract: 120–240 mg daily, standardized to 24% flavone glycosides and 6% terpenoids Tea: Less commonly used due to lower extraction; simmer dried leaves gently and combine with circulatory tonics Combinations: With Gotu Kola for cognitive support and vascular repair With Lion’s Mane for neuroregenerative protocols With Rosemary and Sage for memory blends With Hawthorn for heart and brain circulation synergy With Bilberry for eye and capillary
