The bark and leaves of horse chestnut are medical-but seed extract is most commonly used.
What Is It?
The horse chestnut plant’s seeds and leaves contain a substance that thins the blood. Research shows seed extract can treat chronic venous insufficiency and may have a cancer-fighting effect.
Where Can You Get It?
Found in most drugstores.
How Much Is Enough?
For circulation, 300 mg seed extract containing 50 mg of the active ingredient, aescin, twice daily is recommended.
Do not eat raw horse chestnut-it is dangerous. A standardized seed extract is safe.
