Autumn in many Chinese cities is marked by a particular sight: ginkgo trees turning a brilliant, uniform gold, and the sidewalks beneath them scattered with soft, pale fruit. The fruit smells faintly of something overripe, and inside it sits a small, jade-green seed that cooks, bakers, and grandmothers have prized for centuries. That seed is bai guo (็™ฝๆžœ) โ€” the ginkgo nut, literally the "silver apricot".

In Chinese food therapy, bai guo is a quietly remarkable ingredient. It is not a tonic you eat in generous bowls, the way you might eat goji berries or red dates. It is a seed used in small, counted numbers, dropped into congee, soup, or a light stir-fry. Its traditional character is the opposite of expansive: where many foods nourish by adding, bai guo is understood to work by holding, gathering, and securing. That unusual quality is the whole point of it.

This guide looks at ginkgo nuts through a TCM lens โ€” their nature and flavors, the traditional uses that made them a classic for the lungs and kidneys, how to prepare them safely (this matters greatly), and how to bring them into everyday cooking in the modest quantities that tradition recommends.

What Are Ginkgo Nuts?

Ginkgo nuts are the seeds of Ginkgo biloba, the maidenhair tree โ€” the last surviving member of an ancient plant family that has been on earth for well over 200 million years. Individual trees can live for centuries, and some temple specimens in China are said to be more than a thousand years old. The tree is hardy, slow-growing, and famously resilient, which is part of why it has long carried symbolic weight in Chinese culture as a symbol of longevity and endurance.

The seed sits inside a fleshy, apricot-like outer layer that must be removed and discarded. What remains is a hard, pale shell around a soft kernel; the shell is cracked open and the kernel is what gets cooked and eaten. The kernel itself has a thin brown papery skin and, at its centre, a small green sprout. Both of those inner layers matter for safety, and we will come back to them.

Cooked ginkgo kernels are soft, somewhere between a chestnut and a potato in texture, with a mild, faintly sweet flavour and a subtle bitterness underneath. That gentle bitterness is not a flaw; in TCM it is part of how the seed is understood to act.

TCM Properties of Bai Guo

In Chinese food therapy, an ingredient is described by its thermal nature, its flavours, and the organ channels it reaches. Ginkgo nut has a distinctive profile that explains almost everything it is traditionally used for:

Astringency is the key idea here. In TCM, astringent ingredients are understood to hold and bind โ€” to help the body keep what it should keep, rather than letting it leak or scatter away. Sweetness nourishes and moderates, while a touch of bitterness directs energy downward. Together, this profile points squarely at the two channels the seed enters: the Lungs, which govern respiration and the surface of the body, and the Kidneys, which govern the body's deepest reserves and its control over fluids.

That is why bai guo is traditionally described as both astringing the lungs and settling wheezing and supporting the kidneys in holding urine. It is a seed that helps tighten what has become loose โ€” and, being neutral in nature, it can be used across a wider range of constitutions than strongly warming or cooling herbs.

Traditional Uses in Chinese Medicine

Ginkgo nuts appear in Chinese materia medica going back many centuries. The great Ming-dynasty pharmacologist Li Shizhen discussed them in the Bencao Gangmu (ๆœฌ่‰็บฒ็›ฎ), noting both their traditional uses and the importance of eating only small, well-cooked amounts. Over the centuries, the same handful of applications has recurred.

Securing the Lungs: Cough and Wheezing

The most classic use of bai guo is in patterns of chronic, weak cough and wheezing โ€” especially the kind that lingers long after an illness, where the cough is unproductive and the breath feels shallow or easily lost. In TCM terms, this is described as lung qi failing to hold and gather. Ginkgo nuts appear in several well-known classical formulas composed for this pattern, where they are usually combined with herbs that both support the lungs and help direct qi downward.

Because the seed is astringent, it is traditionally considered a poor choice during the acute stage of a fresh cough with copious phlegm โ€” you do not want to "hold" something that needs to come out. It belongs instead to the later, depleted stage.

Helping the Kidneys Hold: Frequent Urination

Alongside their lung action, ginkgo nuts are traditionally used when the kidneys are described as failing to hold โ€” frequent urination, urgency, and especially night-time waking to urinate. This is understood as a weakness in the kidney's consolidating function, and astringent seeds like bai guo are a recognized approach for gently supporting it. They are often paired with other kidney-supporting foods such as walnuts and Chinese yam in warming soups and congee.

Supporting Women's Health

Ginkgo nut also has a long traditional place in formulas addressing excessive vaginal discharge, where the same astringent logic applies. In classical practice it is typically combined with other herbs rather than used alone, and it appears in well-documented formulas composed for that purpose.

A Note on How It Is Used

It is worth repeating: bai guo is almost never a stand-alone remedy. In Chinese practice it is a supporting ingredient โ€” a small, specific addition to a soup, congee, or formula whose overall direction is already correct. Used that way, its astringent character sharpens the whole dish rather than dominating it.

How to Prepare Ginkgo Nuts Safely

This section matters more than any other on the page, because ginkgo nuts are one of the few foods in the Chinese pantry that are genuinely unsafe if handled carelessly. They are not a "snack by the handful" ingredient. Handled the traditional way โ€” small amounts, cooked thoroughly โ€” they are a normal part of the table across East Asia.

Always cook them. Raw ginkgo nuts should never be eaten. The seed contains natural compounds that are substantially reduced by thorough cooking, and traditional cooking methods evolved precisely for this reason.

Remove two layers, not one. After cracking the shell, peel away the thin brown papery skin. Then, if the kernel is large, split it and remove the small green sprout at its centre. Traditional practice is consistent on this point, and it is the sprout that is generally regarded as the most potent part.

Boil before using. The usual approach is to simmer the peeled kernels in boiling water for at least ten minutes, then drain them and add to your dish. Many cooks boil them briefly first even when they will be simmered again in a soup, which is a sensible extra margin.

Keep the count low. For healthy adults, commonly cited traditional guidance is no more than roughly 5 to 10 cooked seeds per day, and staying at the lower end is wise. Children are more sensitive โ€” those under five are traditionally advised to avoid ginkgo nuts entirely, and older children are usually limited to around five cooked seeds.

Signs of having eaten too many include nausea, vomiting, stomach upset, headache, or restlessness. If someone โ€” especially a child โ€” eats a large quantity, seek medical advice promptly. Fresh nuts should also be kept out of reach of pets, for whom they are more dangerous still.

Ginkgo Nuts in the Kitchen

Traditional cooking uses bai guo sparingly and deliberately: a handful across a whole pot, counted out and distributed. These are the most familiar ways to use them.

Ginkgo and Lotus Seed Congee

A gentle, classic combination for the transitional days of autumn, when the air turns dry and the lungs feel it. Rinse one cup of rice and add 8 to 10 prepared ginkgo kernels, a small handful of lotus seeds, and a few jujube dates if you like. Add plenty of water and simmer until the rice breaks down into a soft porridge. Serve plain or with a little rock sugar. Our guide to congee covers the base technique in more detail.

Ginkgo, Celery and Tofu Stir-Fry

A light, everyday homestyle dish. Prepare 8 ginkgo kernels by boiling them first, then stir-fry with sliced celery and cubes of firm tofu in a little oil, finishing with a pinch of salt. The crisp celery and soft, faintly sweet ginkgo make a clean, simple pairing that is especially welcome in autumn.

Ginkgo and Snow Fungus Sweet Soup

A traditional sweet soup that pairs the astringent seed with the moistening, gelatinous quality of snow fungus. Simmer soaked snow fungus with a few jujube dates and 8 prepared ginkgo kernels until soft, then sweeten lightly with rock sugar at the end. It is a good illustration of a core food-therapy idea: modest, balancing ingredients combined for a gentle overall effect.

Ginkgo in Chicken Soup

For a warming, lung-and-kidney-supporting pot, add 10 prepared ginkgo kernels to a herbal chicken soup along with astragalus or codonopsis. Count the kernels so you know exactly how many are in the pot โ€” that habit of counting is itself part of traditional practice.

Classic Pairings

Buying and Storing Ginkgo Nuts

You will most often find ginkgo nuts in three forms. Fresh in their shells appear in Asian markets in autumn; choose ones that feel heavy and have no soft or mouldy spots. Shelled and vacuum-packed kernels are the most convenient year-round option and are already peeled, though you should still check for and remove the green sprout. Canned or jarred kernels are usually the mildest in flavour but are already cooked, so simply drain and use them.

Fresh unshelled nuts keep for several weeks in a paper bag in the refrigerator. Shelled kernels should be refrigerated in an airtight container and used within a week or two, or frozen for longer storage. Cooked, prepared kernels can be frozen in small portions so you always have a counted handful ready for congee or soup.

Ginkgo Leaf vs Ginkgo Nut

One confusion is worth clearing up directly. The ginkgo nut and ginkgo leaf extract are entirely different products with different traditional and modern uses. The nut โ€” bai guo โ€” is a food, cooked into dishes, and understood in TCM to astringe the lungs and kidneys. The leaf is used to make concentrated extracts, which are a separate preparation altogether. They are not interchangeable, and concentrated extracts should only be used with qualified guidance.

Why This Small Seed Deserves a Place in Your Kitchen

Ginkgo nut is a good example of a broader principle in Chinese food therapy: some foods work through quantity and nourishment, and others work through precision. Bai guo belongs firmly to the second group. A dozen kernels across a pot of congee, a few in a stir-fry, a spoonful of sweet soup โ€” it asks to be used thoughtfully and in small amounts, and it rewards that care with a texture, flavour, and traditional character that nothing else quite reproduces.

Who Should Be Careful?

Because ginkgo nuts are a food with real potency, there are clear cautions to respect.

As always with food therapy, the guiding principle is modest amounts, proper preparation, and attention to how your body responds. A few well-cooked kernels in a pot of soup is food. A careless handful of raw seeds is not.
