Ginkgo (Ginkgo biloba)

The leaves of this tree, a survivor from the dinosaur era, can help with forgetfulness and erectile dysfunction, and may also be useful for asthma, coughs, and atherosclerosis. Ginkgo can be cultivated even in small gardens.

Ginkgo (Ginkgo biloba) is the oldest plant species on earth and is often described as a living fossil. In Chinese herbal medicine, ginkgo has been used for more than 4,000 years to address forgetfulness. A study conducted in 1999 showed that taking ginkgo leaf extract can slow the decline in cognitive function. A daily dose of 120 to 160 mg given to older adults over 12 weeks helped improve concentration and memory, while also reducing sudden mood swings and apathy.

The extract’s effectiveness may be linked to its influence on circulation, since ginkgo benefits the blood vessels in the brain. It strengthens veins and reduces capillary bleeding, which suggests potential benefits for another age related condition, acrocyanosis, meaning the persistent appearance of bruises, especially on the hands and legs.

In 1997, Chinese researchers discovered that ginkgolides have physiological effects that may one day help patients with asthma and prevent the onset of atherosclerosis.

Herbal practitioners recommend ginkgo to enhance mental alertness in people of all ages, and also to treat erectile dysfunction. In China, the seeds and leaves are used to relieve coughs and asthma. The seeds, roasted or pan fried, have a pleasant taste and are believed to ease hangovers.

Ginkgo is cultivated worldwide, can grow up to 40 meters tall, and can live for a thousand years. For small gardens, dwarf varieties are more suitable and usually reach around five meters. Ginkgo thrives in well drained, moist soil. A young tree is sensitive to cold and frost, so it needs protection in winter, and later becomes very hardy.

Warning

At appropriate doses, no harmful effects have been reported, although exceeding the recommended amount may cause stomach upset and dizziness. Ginkgo is not advised for children, pregnant women, those who are breastfeeding, or individuals taking anticoagulant medication. Before any surgery, inform your physician if you are taking ginkgo preparations.
