Ginkgo biloba: what is the secret of these trees to live more than 1,000 years

(and how much they really benefit humans)

The next time you feel old, remember the ginkgo biloba. These trees can live more than 1,000 years and are designed to be almost immortal.

Now a new study reveals the secret of the longevity of these trees Millennials

The investigation, considered the most complete that has been done on the plant aging, offers the first genetic evidence that explains the long life of this species.

The study focused on the genetic analysis of ginkgo trees with ages between 15 and 667 years in the United States and China.

The analysis of the bark, seeds and leaves of the trees showed that their growth does not slow down, even if hundreds of years have passed. In fact, they found that in some cases It accelerates.

The scientists also discovered that the size of the leaves, the photosynthesis ability and the quality of the seeds was not affected by age either.

What is the secret?

YOUNG FOR EVER

Ginkgo biloba can live for several centuries and, paradoxically, are at risk of extinction due to deforestation.

They are native to

China and are the last survivors of an ancient family of trees from which fossils of the last era of the dinosaurs.

They are also known as a maidenhair tree and although they are disappearing in the wild, they can be found in parks and gardens in various parts of the world, where they stand out for their striking yellow leaves During autumn.

The key to their longevity and good health is that they produce chemicals thats protect against stress factors such as diseases or droughts.

Genetic analysis revealed that the tree produces antioxidants, antimicrobial and protective hormones.

In addition, biologists found that old age related genes they are not activated when the tree reaches a certain age, as it does in other species such as herbs or annual plants.

Thus, although the tree is devastated by frost or lightning, all your processes necessary to keep growing healthy continue to function without problem.

“As they age, the ginkgo show no signs of weakening their ability to defend themselves against stress“says biologist Richard Dixon of the University of North Texas, co-author of the study.

According to experts, these types of studies can be useful to better design reforestation programs and understand which trees and where they can bring better ecosystem benefits over time.

DOES IT WORK FOR HUMANS?

In several parts of the world ginkgo biloba extract is sold as a supplement to treat all kinds of ailments, such as memory loss, tinnitus and circulatory problems.

Doctors, however, warn that there is not enough evidence of the benefits of ginkgo biloba in humans.

“The effect of ginkgo on memory improvement has had conflicting results“says the portal of the Mayo Clinic in the USA.

“While some evidence suggests that ginkgo extract might modestly improve memory in healthy adults, most studies indicate that ginkgo does not improve memory, attention or brain function. ”

The clinic also reports that epileptic people, prone to seizures, with bleeding disorders or pregnant women They should not consume ginkgo.

They also warn that raw or toasted ginkgo seeds should not be eaten, since they can be poisonous

The National Health Service of the United Kingdom, meanwhile, warns that ginkgo “not recommended as a treatment for people who are recovering from a heart attack.”
