Ginkgo Biloba

🌿 Ginkgo (Ginkgo biloba)

Ginkgo is one of the world’s oldest living tree species — often called a “living fossil” — traditionally used to support circulation, cognitive clarity, and overall vitality. Modern research highlights ginkgo’s flavonoids and terpene trilactones, which contribute to its antioxidant and neuroprotective reputation. Most consumer products are made from the leaf extract, not the seed (which contains compounds requiring caution).
