Briefly. Ginkgo. What is it?
Ginkgo (or Maidenhair tree) is one of the oldest species on this planet, growing almost unchanged 100 and more million years ago. These trees are grown as horticultural plants and on plantations for commercial use. The leaves have a specific form. The tree can live up to 4500, and often over 1000 years.
Ginkgo grows very slowly and the trees can be very large. Ginkgo trees can be extremly large but they grow very slow. There are male and female plants. Female plants bears fruit in Autumn, which is similar to plums. The fruit is in the middle of a hard seed such as nuts and it can be used as food.
The Ginkgo is a unique tree with no close living relatives. For centuries it has been believed that Ginkgo has extincted in the wild, but now it is known to grow wild in at least two small areas in eastern and southeastern China.
The Chinese people traditionally use leaves and fruit nuts, for food and medicine. And although the fruits and leaves of this plant has been used in China for nearly 4-5,000 years, its usage in Western medicine did not begin until the 1950s. Ginkgo is a medicinal plant. Modern science has confirmed this. Major of Ginkgo leafs is being used for tea, and for Ginkgo extract from which we can get variety of medications. Today, Ginkgo is grown on all continents.
