Historical Background

Ginkgo is a 'living fossil' — the last survivor of an ancient plant family — and a sacred tree of Chinese and Japanese temples. Its fan-shaped leaves brew a mild tea traditionally associated with circulation and memory, and ginkgo leaf extract is among the most studied herbal preparations.

Earliest recorded uses: Used in Chinese medicine for millennia; a 'living fossil' tree; leaf tea for circulation traditions.

Traditional Uses

These uses document historical traditions and do not imply proven effectiveness.

Flavor & Aroma

Aroma: Mild, slightly nutty, green, faintly sweet

Tea Information

Research Summary

Ginkgo leaf extract has conflicting evidence for cognition and circulation; large trials (e.g., GEM) found no clear benefit for memory in older adults. It is not a treatment for dementia, tinnitus, PAD, or any disease, and may increase bleeding risk; discuss with a clinician.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
