How Safe is Ginkgo Biloba?

Some warnings to consider before taking the ‘memory activator’ capsule.

A few years ago, Ginkgo Biloba was only recognized as a cerebral activator for old people. It was usually known as the 40 mg Tebokan tablet. Nowadays new companies produce this herbal medicine in soft gel capsules with the increased dose of 500 mg.

As an over-the-counter and prescription drug, Ginkgo biloba has been one of the most top selling product in most countries. In the Philippines, students from high school to college levels enjoy the benefits of this herbal drug for its brain power.

Ginkgo Biloba is also known as Maidenhair tree, Kew tree and Japanese silver apricot. It is referred to as a living fossil because it is believed to be the oldest living specie at about 200 million years old. While the seeds of Ginkgo tree have been used in tradition Chinese medicine for 4000 years, the extract of Ginkgo leaves is used medicinally in North America and in most parts of the world.

    In addition, Gingko Biloba may affect the following:

  •  Ginkgo may result in uncontrolled bleeding or hemorrhage. It should not be taken with antiplatelet or anti-clotting drugs e.g  clopidogrel, ticlopidine, warfarin, heparin, and aspirin.
  • Certain herbs, such as danshen, devil’s claw, eleuthero, garlic, ginger, horse chestnut, papain, red clover, and saw palmetto, can also increase the risk of bleeding if combined with ginkgo.
  • Ginkgo has been found to interfere with the metabolism of drugs processed by an enzyme called cyp3A4.
  • As stated above, Ginkgo may increase the risk of seizures. It should not be taken with the following:

1.       antidepressants

2.       antibiotics such as penicillin and cephalosporins

3.       Corticosteroids

4.       Drugs that suppress the immune system  (azathioprine and cyclosporine, borage, evening primrose, and wormwood)

  •  Ginkgo shouldn’t be used with the drug cyclosporine (used to suppress the immune system), because it  has been found to decrease the effect of that drug.
  •  Ginkgo may interact with insulin and other drugs for diabetes, such as metformin (Glucophage), glyburide (Glynase), glimepiride (Amaryl), and glipizide (Glucotrol XL).
  • There have been some cases of high blood pressure in people taking Ginkgo and thiazide diuretics.

So, there you go folks. Just a reminder, herbal medicine as it is, Ginkgo Biloba should also be consulted with your doctor to avoid unnecessary complications.

  2. Very useful information..

  3. Good info on this herb. Used to take Ginko daily but stopped taking it a few years and ironically cannot remember why I stopped taking it.

  4. Very well written. The bonsai society have even come up with the version of this plant. I must say no pain no gain so people in need just have to take the risk. Nice post kabayan.

  5. very informative piece.

  6. Nice write!
    “Ginkgo has been found to interfere with the metabolism of drugs processed by an enzyme called cyp3A4.”

    Watch out with it, this particular enzyme is for the biodegradation of older anti-depressive medication and for things like barbiturates.

    I’m curious however in which doses the dangers come prevalent though, it’s a herb and most herbs are only dangerous (generally) in high dosages.

  7. very nice\’ but what is the recommended dosage for the students (as they use it as a memory enhancer)?
