Botanical Description

A large ancient deciduous tree with distinctive fan-shaped bright green leaves with radiating veins turning golden in autumn, and small plum-like yellow-orange seeds with a kernel; the leaves are the part used.

Also known as: Maidenhair Tree, Yin Xing, Fossil Tree

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 Preparation

Modern Evidence

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.
