In the Mesozoic era, a class of this plant already numbered numerous species throughout the world. Therefore, nowadays, it is impossible to find a plant that is similar to ginkgo biloba. For the first time, the healing properties of this wonderful plant were discovered in ancient China. At that time, mainly seeds of this herb were used for the treatment of respiratory diseases as well as diseases of the liver and bladder. Nowadays, ginkgo is also used to relieve symptoms of asthma and sometimes as a secondary drug for bronchitis.

Some scientists believe that this plant has a magnificent effect in the treatment of memory disorders in Alzheimer’s disease; in addition, it improves memory of healthy people. However, judging by the results of the studies recently completed by American medical scientists, this plant neither prevents the decline of intellectual abilities of the person nor slows the development of Alzheimer’s disease. One of the longest and most rigorous studies ever conducted with ginkgo biloba did not find evidence that it can prevent the disease among the elderly who have problems with memory. Dementia occurs in every third person after 65 years. At present, it appears that in the fight against dementia, there is no medicine but regular physical activity, healthy eating, and healthy lifestyle (Pizzorno & Murray, 2012).
