Ginkgo tea safety concerns addressed in this article, along with answers to other common questions about the herbal beverage.
Can ginkgo tea be made safe?

It’s Q&A Day at 10almonds!

Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!

In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

So, no question/request too big or small 😎

❝I’d be interested in OTC prostrate medication safety and effectiveness.❞

Great idea! Sounds like a topic for a main feature one day soon, but while you’re waiting, you might like this previous main feature we did, about a supplement that performs equally to some prescription BPH meds:

❝Was very interested in the article on ginko bilboa as i moved into a home that has the tree growing in the backyard. Is there any way i can process the leaves to make a tea out of it.❞

Glad you enjoyed! First, for any who missed it, here was the article on Ginkgo biloba:

Ginkgo Biloba, For Memory And, Uh, What Else Again?

Now, as that article noted, Ginkgo biloba seeds and leaves are poisonous. However, there are differences:

The seeds, raw or roasted, contain dangerous levels of a variety of toxins, though roasting takes away some toxins and other methods of processing (boiling etc) take away more. However, the general consensus on the seeds is “do not consume; it will poison your liver, poison your kidneys, and possibly give you cancer”:

The leaves, meanwhile, are much less poisonous with their ginkgolic acids, and their other relevant poison is very closely related to that of poison ivy, involving long-chain alkylphenols that can be broken down by thermolysis, in other words, heat:

Leaves, seeds and exocarp of Ginkgo biloba L. (Ginkgoaceae): A Comprehensive Review of Traditional Uses, phytochemistry, pharmacology, resource utilization and toxicity

However, this very thorough examination of the potential health benefits and risks of ginkgo tea, comes to the general conclusion “this is not a good idea, and is especially worrying in elders, and/or if taking various medications”:

Medicinal Values and Potential Risks Evaluation of Ginkgo biloba Leaf Extract (GBE) Drinks Made from the Leaves in Autumn as Dietary Supplements

In summary:

  • Be careful
  • Avoid completely if you have a stronger-than-usual reaction to poison ivy
  • If you do make tea from it, green leaves appear to be safer than yellow ones
  • If you do make tea from it, boil and stew to excess to minimize toxins
  • If you do make tea from it, doing a poison test is sensible (i.e. start with checking for a skin reaction to a topical application on the inside of the wrist, then repeat at least 6 hours later on the lips, then at least 6 hours later do a mouth swill, then at least 12 hours later drink a small amount, etc, and gradually build up to “this is safe to consume”)

For safety (and legal) purposes, let us be absolutely clear that we are not advising you that it is safe to consume a known poisonous plant, and nor are we advising you to do so.

But the hopefully only-ever theoretical knowledge of how to do a poison test is a good life skill, just in case 🙂

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
