Ginkgotree & ecoturism - fanclub

If you have a young ginkgo plant at home or there is one of these precious trees growing in your surroundings or your attention have been attracted by an information on ginkgotree leaves extract than my website is aimed at you too as it reports detailed information on this tree and its usefulness for the man and the nature. Also the website is aimed at the ecoturism, heath and healthy lifestyle, gastronomic customs included - here you can post your photos, travel recommendations, tour tips and sentences publicly. In the case you are in business in the field of nature extracts and vitamins then allow me attract your attention to little known group of nature products - plant resistance improvers. These nature products are used mainly in Germany and Austria in the practice. In this field I can offer you my experience and services too (contacts, creating websites etc. - see ). Your reactions are welcome.

Ginkgotree - Maidenhair tree
(Ginkgo biloba LINNÉ)

History and inclusion
It is resident in China and Japan, where it is held in the parks and at temples as ornamental and medicinal tree. In some China´s provinces the Ginkgotrees are to be found still wild. Oldest notes over Ginkgo come from the 11th century. In Europe it becomes resident since 18th century again. Oldest Ginkgotree in Europe has date of birth 1730 and address Botanical garden Utrecht, Holland. Later these trees were spread also in England, France, Germany, Italy, North America, Austria-Hungary and other countries. Some beautiful exemplares of Ginkgotree are also in Vienna - in Stadtpark and near the city hall. These trees are to be found in Bratislava too - see the photo Ginkgotree  in the autumn - and in other cities of the Slovakia.

 The Ginkgotree is the only still living representative of a whole class by Ginkgoopsida on the Earth that in Middle Ages (200 -150 million years ago) in all continents was widespread. Sometimes it is thus designated as the oldest tree at all and living fossil. It is the only living link between low and higher plants, between ferns and conifers. Already the dinosaurs ate the Ginkgos! I
t is the symbol of the symbiosis, longevity and strong immunity

Similarly as the maple Ginkgotree grows cca 30 m high. Individual trees can live for a very long time - 1000 years, also more. It blooms from May to June, whereby male and female blooms grow on different trees - Ginkgos are dioecious. Small, yellow-green male blooms occur into compound, down-hanging blooms (pollen cones), which are similar to the male blooms of maple or birch. Yellow-green female blooms - ovulves grow individually or in pair on short stalk as seed germ of the future fruits. The fruits (seeds) are similar to the Mirabell plum or cherries - yellow to orange yellow seeds, diameters cca 1.5 - 2 cm, with the core. In Japan and in China the Gingkoseeds are frequently eaten and have characteristic spicy taste. In good Chinese restaurant you can order Gingkospirit at any time - taste alcoholic Gingko beverages as aperitiv. Male plants, which occur more frequently, sprout in spring cca 2 weeks former as female plants. Afterwards one can differentiate between female and male plants - if these grow in the same conditions. Ginkgo leaves serve as tea (diuretikum and phytopharmakum). One can also cultivate Ginkgotree on the balcony or in the flat without problems and  in this way supply oneself with the healthy raw material for a tea which can receive our health up to high age (see to illustration - cultivation of Ginkgo on the balcony). In Slovakia is Ginkgo relatively little known. In the world the Ginkgo leaves serve as raw material for the production of common sold nature extracts.
In the botany is the Ginkgotree model of the resistance ability opposite parasits - all the same whether mushroom diseases, insect or industry air pollutants. Two Ginkgotrees in Hiroshima survived 6.8.1945 even the atom bomb explosion - see Also one can hardly find mistletoe as parasite on the Ginkgotree. As it is so old, it learned best that own strong immunity is the best weapon opposite all parasits. As basis of this excellent resistance the scientists determined extraordinary ability of the Ginkgotree to transport the nutrients into all cells of the plant and operational readiness to use strong antioxidants (cca 100-times stronger than C-vitamin) for the elimination of the free radicals in each cell of the plant. In addition the symbiosis of the Ginkgotree with so far not well-known alga was proven recently …

Effect and molecular structure

The Chinese medicine knows Ginkgo for 5000 years. For the drug are proven under other following effects:

  • Promotion of the blood circulation, preferably within the range of the micro circulation
  • Improvement of the flow characteristics of the blood
  • Inactivating toxic oxygen radicals (Flavonoide)
  • Neuroprotective effect (Ginkgolide A and B, Bilobalide)
  • Increase of the memory performance and the learning ability
  • Increase of the oxygen deficiency tolerance, in particular brain tissue
  • Antagonism opposite Platelet activating factor (Ginkgolide), i.e. prevention of blood coagulation
  • Antibacterial and anti-virus effects

For the explanation of the molecular stucture of the Bilobalide, Ginkgolide and their synthesis Professor E.J. Corey (the USA) received the Nobel Price in the year 1990. Website  brings closer details.


The Ginkgo leaves serve as raw material for the production of the Ginkgo biloba extract, which is at present the most sold plant medicament in the world. Perhaps weaker form of the Ginkgo extrakts - the Ginkgo tea - knows everyone. German company Dr. Wilmar Schwabe, Karlsruhe patented the method of acetone-water extraction world-wide. The extract is characterized by 22 - 27% Flavonglycoside, determines as Quercetin and Kaempferol inclusive Isorhamnetin (with HPLC) and as Acylflavone with the mol mass M = 756.7 (Quercetinglycoside) and M = 740.7 (Kaempferolglycoside), furthermore 5 - 7% Terpenlaktone, of it approx. 2.8 - 3.4% Ginkgolide A, B and C as well as approx. 2.6 - 3.2% Bilobalid. Content of the Ginkgol acid is under 5 ppm. Ginkgo biloba extract is sold in several preparations under different brand names, from which Tebokan and Tanakan are admitted in Slovakia and Tebonin in Austria.

The monography over Ginkgo “Elixir of Youth” by the Christopher Hobbs (Botanica press, 1991) states several indications to the usage of Ginkgo preparations. Old Chinese medicine already treated the memory disturbances, concentration disturbances, depressive detuning, ear rushing, some eye diseases and headache before 5000 years with medicaments of Ginkgo. New knowledge points out that the list of the diseases, and/or areas where Ginkgo helps is broader. It seems to have a sense  to use preparations of Ginkgo biloba inclusive Ginkgo tea everywhere, where weak blood circulation occurs (cold feet and hands, ear and eye weakness under weak blood circulation, arthritis, rheumatism etc.). Ginkgo helps particularly with potency disturbances, which are caused by a bad blood circulation. One can incorporate Ginkgo preparations thus also to aphrodisiac, which strengthen the libido and which energize sexual live well. Furthermore the Ginkgo preparations protect the human organism against effects of the polluted environment and coherent disturbances (cough, bronchitis, asthma, weak immune system, allergic diseases etc.) and gives also stress support. Perhaps the most important protection can the Ginkgo preparations ensure against the unwanted effect of free radicals (Alzheimer´s disease, prevention of the heart attack and the brain impact and some forms of cancer).

Warning: In the case of particular illness consult your physician or pharmacist before taking a preparation with the Ginkgo biloba extract whether it is suitable.for you. Regular taking of Ginkgo biloba preparations leads to the reduction of the coagulating ability of the blood and therefore in the case of threatening operation  one must stop taking the Ginkgo preparations in time

Cultivation of Ginkgotree

Seed more fertilized Ginkgo seeds in covered container with wet sand in March. After 1 - 2 months take out germinating seeds and plant them in flower pot or in the garden.Young Ginkgo plant needs nearly full shade for first 2 - 3 years. Only if the young Ginkgo tree is high at least 30 cm, it can enjoy full sun. If small Ginkgo tree in free nature is planted, then must be protected  the south side with a broad board or with bush, several corn plants or with other biological material  (see illustration - young Ginkgotree with the sunlights shaded from south side). Young Ginkgotree prospers well in light soil or in the substrate, which consists of 1 part sand and 1 part humus. Too much water could destroy also the young Ginkgo plant by dying the roots. Flower pot for Ginkgo must have therefore a hole. It is recommended to fertilize with the chicken muck and not with synthetic commercial fertilizer.
In Bratislava you can assume the Ginkgo tree annual increasing 15 - 20 cm on the balcony - however, if the flower pot is sufficiently large. In free nature the increases are still more favorable. To cultivate a Ginkgo in order to enjoy a harvest of the Ginkgo fruits in the garden or in the park, it is recommended to plant at least 3 - 4 trees at the same time on the same plot, whereby at least one plant must have female sex. In case of cultivation of the Ginkgo trees in free nature we should consider predominant wind direction in the area and facilitate thus the way of the pollen from the male Ginkgotree to female Ginkgotree. It is recommended to keep distance up to 100 m between female and male Ginkgotree. We obtain best conditions for pollination however if we cultivate the Ginkgotrees both sexes pushed next to each other . With the female Ginkgotree you must count then after 20 - 35 years on falling fruits, which do not spread right aromatic smell for everybody. First 2 years we protect young Ginkgotree against the frost - we cover it at the end of the autumn with branch needles or with dried leaves.


A clever scientist once said : “Each man should have a Ginkgo of his own”. Thus one can only agree.
...because the one, who cuttivates the ginkgo, obviously thinks of next generation and behaves responsibly towards both himself and the nature .... or has already begun to think about it.

Photo album

The photographs from many places prove that the Ginkgotree prospers best in free nature. This extraordinary tree can be ornament of each garden - it depends only on us whether we find the suitable place to its existence in our thoughts and hearts . Photo - click here.

The principal purpose of the Ginkgotree & ecoturism funclub (non-formal, non-commercial and free association of ginkgo friends) would be spreading the Ginkgotree information in Slovakia and EU, their protection and creating better terms for widening the Ginkgotree cultivation in Slovakia and EU. The further goals of the Ginkgotree funclub are the spreading information about ecoturism and immunity of the plants and application of the natural plant resistance improvers . We can partly regard these means for analogy of the homeopathics in human medicine. By nature substance is to be understood a chemical compound arised by the evolution of molecules in free nature as result of natural biochemical processes in by humans not affected and/or  only few and reversibly affected biosystems and it can be identified also today in living nature - not however as residue after application of chemical substances those the human invented /Nemeček 1999/.
