What is Ginkgo Biloba?
The ginkgo tree gave the dinosaurs a run for their money and is now considered a “living fossil,” dating all the way back to the Jurassic period.
Also known as the ginkgo biloba tree or maidenhair tree, it has no botanical relatives and was even thought to be extinct up until the 1600s when it was found in Japan in monasteries and temple gardens of Buddhist monks. Ginkgo is incredibly resilient, can live to be 3,000 years old and has even survived atomic bomb explosions.1 You read that right.
Leaf it to Ginkgo Biloba for Health and Wellness BenefitsWith its prehistoric track record and complete disregard for extinction, it’s not surprising that ginkgo biloba extract has some hearty health benefits. From brain boosts to mood support, heart benefits and more—you better beleaf ginkgo can lend a limb to your wellness routine.
Memory and CognitionOne of the better-known uses for gingko biloba is its brain-boosting capabilities. This extract may boost memory when paired with panax ginseng (Korean ginseng) and may also promote healthy cognitive function.2,3 Ginkgo’s ability to promote brain function may be due to promoting blood flow to the brain, but it doesn’t hurt to add neuro-friendly nutrients to your diet as well.
Immune HealthOne of the lesser-known benefits of ginkgo biloba is its immune-boosting properties. Ginkgo is packed with antioxidants and flavonoids, which helps the body get rid of toxins.4 This boosted antioxidant activity can lend a hand to promoting healthy immune function.5
Heart HealthStudies have shown that ginkgo biloba can support heart health.6 Ginkgo contains terpenoids, organic compounds that promote blood circulation by dilating blood vessels and preventing platelets from sticking.7 This improved circulation makes it easier for your heart to pump blood and function properly. While ginkgo biloba is better known for improving brain function, it’s hard to ignore these circulatory benefits for heart health.

Ginkgo biloba may promote relaxation and provide support to cope with everyday stress and tension.8 This extract may also benefit a healthy mood and support positive thinking.9 Branch out by pairing ginkgo biloba with your favorite wind-down rituals to get some quality R&R.
