What is Horse chestnut extract?

Horse chestnut extract powder is derived from the seeds of the horse chestnut tree (Aesculus hippocastanum). Horse chestnut is native to areas of Europe, but is now grown in many areas around the world. Aescin (also spelt escin) is the most abundant active compound of horse chestnut extract and exhibits a range of actions.

Historically, horse chestnut has been used for purposes as diverse as a whitening agent for fabrics and as a soap. More recently it has been found to be of benefit in disorders of the venous system, particularly chronic venous insufficiency. It has also been used in the past to help with haemorrhoids.

Several studies have shown that horse chestnut extract is better than placebo for improving the symptoms of chronic venous insufficiency. One study has shown it to be equivalent to using compression stockings for reducing oedema or swelling. This study showed a reduction of about 25% of oedema fluid over a 12 week period.

Horse chestnut extract is currently used as an alternative to compression stockings for those who are unable to use compression. Common reasons for not using compression include those who are unable to tolerate compression, have peripheral vascular disease, find it to difficult to use, or simply do not wish to use compression.

How does it work?

Studies have suggested several different actions that are desirable in some diseases. Horse chestnut extract powder appears to impair the action of platelets (important components of blood clotting). It also inhibits a range of chemicals in the blood, including cyclo-oxygenase, lipoxygenase and a range of prostaglandins and leukotrienes. These effects result in reduced inflammation and reduced blood pressure. Horse chestnut also reduces swelling by constricting vessels of the venous system and slowing the leakage of fluid out of the veins.

 Functions of Horse Chestnut Extract    

1. Strengthens vein walls, increases elasticity, and decreases permeability (leakage).

2. Decreases edema -swelling caused by accumulation of fluid in the veins.

3. Reduces venous inflammation.

4. Stimulates circulation.

5. Treats hemorrhoids (traditional).
