[48] The shrine is in the city of Kamakura, Kanagawa Prefecture, Japan. [35][36] Whether native ginkgo populations still exist has not been demonstrated unequivocally, but there is genetic evidence that these Southwestern populations may be wild, as well as evidence that the largest and oldest Ginkgo biloba trees may be older than surrounding human settlements. Native to China,[2] the tree is widely cultivated, and was cultivated early in human history. [72][73][74], According to a systemic review, the effects of ginkgo on pregnant women may include increased bleeding time, and there is inadequate information about safety during lactation. At least morphologically, G. gardneri and the Southern Hemisphere species are the only known post-Jurassic taxa that can be unequivocally recognised. However, high genetic uniformity exists among ginkgo trees from these areas, arguing against a natural origin of these populations and suggesting the ginkgo trees in these areas may have been planted and preserved by Chinese monks over a period of about 1,000 years. The tree was nicknamed kakure-ichō (hiding ginkgo), derived from an Edo period legend in which Minamoto no Sanetomo is assassinated on 13 February 1219 by his nephew, Kugyō, who had been hiding behind the tree.

[35] This study demonstrates a greater genetic diversity in Southwestern China populations, supporting glacial refugia in mountains surrounding eastern Tibetan Plateau, where several old-growth candidates for wild populations have been reported. More studies are needed to determine the significance of these findings. This ancient herb acts to enhance oxygen utilization and thus improves memory, concentration, and other mental faculties.

The implications would be that G. biloba had occurred over an extremely wide range, had remarkable genetic flexibility and, though evolving genetically, never showed much speciation. While it may boost cognition in older populations, this effect is not very reliable or generalizable.
