Ginkgo

Ginkgo (Ginkgo biloba Ginkgoaceae)


Other Names: Maidenhair Tree, Living Fossil

Described by Charles Darwin as a "living fossil," Ginkgo biloba is the oldest surviving tree species, thriving in China over 200 million years ago. Individual trees can live for over a thousand years. Introduced to Europe in the 18th century, ginkgo is valued as an ornamental tree.


Parts for Use

Leaves

  1. Ginkgo is cultivated for the pharmaceutical industry, notably in France and America.
  2. Leaves are harvested using machines that cut branches from young trees.
  3. Leaves are used to produce tinctures, dry extracts, and various pharmaceutical products.

Ingredients

Ginkgo’s active components include ginkgolide terpenes and polyphenol flavonoids, which act as antioxidants to strengthen blood vessels and improve circulation.


Use in Treatment

Ginkgo has been used in Chinese herbal medicine for over 4,000 years to address forgetfulness in the elderly. A 1999 study showed that 120 to 160 mg of ginkgo extract daily for 12 weeks improved concentration, memory, and reduced sudden mood swings and apathy in older adults. Its effects are linked to enhanced blood circulation, particularly in aging brain blood vessels. Ginkgo strengthens veins, reduces capillary bleeding, and may alleviate acrocyanosis, a condition causing persistent bruising on hands and feet. Chinese research suggests ginkgolides could benefit asthma and prevent atherosclerosis. Ginkgo is also prescribed to enhance mental alertness and treat impotence.


Cultivation

This hardy tree thrives in rich, well-drained soil in a sunny location.
