Ginkgo Biloba: Benefits, Uses, and What the Science Says

When people talk about ginkgo biloba, a traditional herbal supplement derived from the leaves of the ginkgo tree, used for cognitive support and blood flow. Also known as maidenhair tree extract, it's one of the most studied botanicals for brain health and circulation. Unlike synthetic drugs, ginkgo biloba isn’t a quick fix—it’s a slow-acting plant compound that works over weeks, not hours. Many take it hoping to sharpen memory, reduce brain fog, or improve circulation in their hands and feet. But does it actually work? And who should avoid it?

It’s often grouped with other herbal supplements, natural products taken for health benefits without a prescription. Also known as botanicals, these include things like turmeric, ginseng, and echinacea. Ginkgo biloba stands out because it’s been tested in dozens of clinical trials, especially for older adults. Studies show it may help with mild memory issues linked to aging, but it doesn’t reverse dementia. It’s also used to support blood flow in the legs, especially in people with intermittent claudication—where walking causes leg pain due to poor circulation. The active ingredients, flavonoids and terpenoids, act as antioxidants and help relax blood vessels. That’s why it’s sometimes paired with other supplements for heart or brain support.

But it’s not harmless. Ginkgo biloba can interact with blood thinners like warfarin or aspirin, raising the risk of bruising or bleeding. It may also affect blood sugar levels, so diabetics should watch for changes. And while it’s sold as a supplement, quality varies wildly—some products contain little to no actual ginkgo, while others have contaminants. That’s why checking third-party tested brands matters more than price.

People who take it for memory often don’t see results right away. Most studies suggest at least 6 to 12 weeks of daily use before noticing any difference. And it’s not for everyone—pregnant women, people with seizure disorders, or those preparing for surgery should skip it. If you’re already on meds for depression, anxiety, or blood pressure, talk to your pharmacist before starting.
