Ginkgo Biloba: 4 Health Benefits of This Herbal Remedy
Ginkgo biloba, derived from the leaves of the ancient ginkgo tree, is a popular herbal supplement with roots in Traditional Chinese Medicine (TCM). Renowned for its potential to boost brain function, improve blood circulation, and combat oxidative stress, ginkgo biloba has gained attention as a natural remedy for various health concerns.
This article explores the science-backed benefits, potential uses, and safety considerations of ginkgo biloba supplements to help you make informed decisions about incorporating them into your wellness routine.
What Is Ginkgo Biloba?
Ginkgo biloba, also called ginkgo biloba leaf extract, comes from the fan-shaped leaves of the ginkgo tree. This tree, often referred to as a "living fossil," has survived for over 200 million years. Its extracts are rich in antioxidants like flavonoids and terpenoids, which may help combat cell damage and promote overall health.
Top Health Benefits of Ginkgo Biloba
1. Supports Memory and Cognitive Function
Ginkgo biloba is often praised for its potential to enhance memory and cognitive performance, particularly in older adults.
Research Insights:
A review of 21 clinical trials revealed that combining ginkgo biloba with conventional Alzheimer’s treatments may improve cognitive function in individuals with mild symptoms. However, the studies varied in size and quality, and more robust evidence is needed.What It Means for You:
While ginkgo biloba may offer mild benefits for age-related cognitive decline, it’s not a proven treatment for Alzheimer’s or other severe conditions.
2. Promotes Eye Health
The antioxidants in ginkgo biloba may benefit vision by improving blood flow to the optic nerve and retina.
Potential Benefits:
- May slow the progression of glaucoma by reducing optic nerve damage.
- Could support retinal health and reduce the risk of macular degeneration.
Study Limitations:
Evidence remains inconclusive, with small-scale studies suggesting modest improvements in some participants.
3. Reduces Anxiety and Depression Symptoms
Ginkgo biloba’s role in mental health stems from its antioxidant properties, which may help regulate mood.
Notable Findings:
A study showed that 480 mg of ginkgo extract daily reduced anxiety symptoms in individuals with generalized anxiety disorder. Additionally, pairing ginkgo with antidepressants improved post-stroke depression symptoms in older adults.Important Note:
These findings are preliminary, and ginkgo biloba is not a substitute for professional mental health treatments.
4. Lowers Blood Pressure
By improving blood flow and reducing clotting, ginkgo biloba may help manage high blood pressure (hypertension).
- Research Highlights:
- A 2014 review found mixed results, with some trials showing reduced blood pressure and others indicating no significant effects.
- A small 2018 study supported its potential for lowering arterial hypertension.
