Bai GuoA traditional Chinese herb dedicated for coughs and combating aging, Ginkgo nuts, or Bai Guo, are one of the most popular and famous supplemental options.

As for methods of preparing gingko nuts, there are many excellent options out there, such as frying, roasting, boiling, accessories to main ingredients, cookie, preserved fruit, can, beverage, and liquor, etc.

What are ginkgo nuts?

Actually they refer to the seeds of ginkgo tree, also known as Ginkgo biloba in Latin and Yin Xing in Chinese. This is one of rare Deciduous Trees with orange-yellow drupe fruit, which blossoms in May and matures in October. As the oldest existing plant seeds of the relict plant, it is the only one survivor in this genus. Ginko biloba grows slower but life is way much longer, even up to thousands of years. Currently the oldest ginko tree is found in Di Lin Temple, which locates in Fu Lai Mountain, Ri Zhao, Shangdong province. It is said that it dates back to Shang dynasty, more than 3,500 years ago.

The earliest evidence about Gingko biloba was found in Carboniferous nearly 3.5 billion years go. They were ever widely distributed in Europe, Asia, and America in the northern hemisphere during Jurassic Period of Mesozoic but later declined gradually in Cretaceous Period. About half million years ago, Quaternary glaciation began and the cold killed most of the ginkgopsida. Somehow only some species in China survived this disaster. Also called as living fossil and panda plant, wild Gingko biloba communities are found in just a few places in China. Due to small population and dioecious nature in the wild, to protect this rare species now most of maidenhair trees are cultivated. No doubt, all of them worldwide are all originated from China, directly or indirectly.

Ginkgo nuts are oval or subglobose, 2.5 to 3.5 long, and about 2cm in diameter. Its outer fleshy seed coat is with white powder, faint yellow or orange-yellow when ripe; middle sclerotin seed coat is white, with 2 to 3 ridges; internal membranous seed coat is with rich endosperm.

    Very interesting article… The recipe seems like it has many health benefits, but does it taste good?

      It is hard to say since people’s taste differs from each other. Some people think ginkgo nuts are tasty but some others don’t think so.

    Oh my! I was going to buy ginko nuts on amazon, but now I am afraid to get them at all. Never knew they were toxic. Glad I read this article.

      When it comes to consumption of ginkgo nuts, dosage is the key here. If you follow the suggested amount, you’ll be just fine by maximizing the benefits while minimizing the toxic.

  3. another

    Other sites offer 10/day for adults or 4/day for children as the safe dosage rather than 40 to 300 and say not at all if on blood thinners or blood pressure medicine (and some other specific drugs).

    1. Hahahahahahaaaa...u suck.

      I believe you misunderstood the article. It says “regular dosage is 6 to 10 grams, or 5 to 10 pieces”. It further says “the over dose is 7 to 150 pieces for children and 40 to 300 pieces for adults.” 40 to 300 is the toxic overdose, not the regular dose. Please read your articles SLOWLY, or, read it twice if you weren’t able to understand it fully the first time. Thanks.

      Ginkgo biloba may increase the effect of blood thinners (Anticoagulants and antiplatelet drugs). When combined with clopidogrel, ticlopidine, warfarin, heparin, aspirin, etc., this herb may lead to uncontrollable bleeding or bleeding.
