Ginkgo biloba leaves

Ginkgo biloba


The Ginkgo biloba, or maidenhair tree, originated in China nearly two million years ago and is the oldest species of tree on earth. Its leaves and seeds have been used as natural remedies for centuries. Yet it’s only in recent decades that medical researchers have found evidence that ginkgo may play an important role in treating conditions such as Alzheimer’s disease and dementia, which lead to lack of concentration, confusion, inability to assimilate new information and memory loss. Ginkgo biloba is widely studied and in Germany and China it is a commonly prescribed herbal medication.

Parts used



The active ingredients in ginkgo biloba are flavonoids (which have powerful antioxidant properties), ginkgolides (unique compounds that suppress a clot-promoting substance in the body) and a sesquiterpenoid called bilobalide.

Medicinal uses

Apart from ginkgo biloba’s usefulness in treating patients with conditions such as dementia and Alzheimer’s disease, it may also be recommended in cases of arteriosclerosis, cerebral hypoxia, strokes, hypertension, hearing loss, vertigo, tinnitus, macular degeneration, Parkinson’s disease, intermittent claudication (leg cramps), altitude sickness, occlusion of the arteries and Raynaud’s disease.

Ginkgo biloba is prescribed to:

  • Regulate the tone of blood vessels, increasing the flow of blood and improving brain and body function.
  • May make blood less ‘sticky’, reducing the risk of blood clots.
  • May slow down the progression of tissue degeneration and relieve depression in people with dementia and Alzheimer’s disease.
  • Ginkgo biloba leaf extract may encourage pain-free walking in patients with intermittent claudication (painful leg cramps), peripheral vascular disease and Raynaud’s disease.
  • May bring relief from migraine.
  • May ease vertigo and equilibrium disorders.
  • May ease breast tenderness and other symptoms of pre-menstrual syndrome.
  • May help in cases of tinnitus.
  • May be useful in cases of arteriosclerosis.
  • May helps in cases of strokes and hypertension.
  • Some studies suggest that ginkgo may help to treat macular degeneration.
  • It is reported to reduce inflammation, especially in the treatment of multiple sclerosis – where nerve tissue is damaged by inflammation.
  • Used in China to treat asthma.


Talk to your medical practitioner before taking any herbal supplements.
Ginkgo biloba is generally considered safe, but it may cause mild gastrointestinal upset, headache, dizziness, palpitations and constipation. Larger doses can cause restlessness, diarrhoea, nausea, vomiting and weakness. Do not take ginkgo if you are pregnant or breastfeeding. It is not advisable to embark on any course of herbal remedies without consulting your natural medicine practitioner. Remember also that although ginkgo has shown some success in treating ailments related with old age, it will not reverse the ageing process.

This native of China is grown all over the world for its novelty and its beauty. Ginkgo is an erect, slow-growing deciduous tree that bears pretty soft green, two-lobed leaves. Male and female flowers are found on separate trees and fruit will only form when they are planted near each other. Plant this hardy specimen in full sun in fertile, well-drained soil.
