Horse Chestnut – A remedy against Circulatory Problems

Horse Chestnut – A remedy against Circulatory Problems

In recent times, horse chestnut has become a remedy for those who suffer circulatory problems. Swollen legs are caused by a bad blood flow, resulting in varicose veins that affect both women and men. However, recent studies have proven that the properties of horse chestnut go beyond. This is due to the fact that it can even be a great antioxidant or support for male fertility.

What is the Horse Chestnut?

Horse chestnut or Aesculus hippocastanum is also known as conker tree. However, it has nothing to do with the traditional chestnut tree.

The first difference is that its fruits are not edible (this is important, since it eating them can trigger side effects). It does have medicinal properties due to the many active ingredients that are contained in its different parts.

Properties of Horse Chestnut

  • Flavonoids, phytosterols and allantoin in its bark.
  • Campentrol and kenferol in its leaves, as well as flavonoids and phytosterols too.
Thanks to all these properties, horse chestnut protects our organism especially against clots or cardiovascular diseases. Moreover, it also improves the capillary resistance.

Horse chestnut contains anti-inflammatory elements. It helps to treat problems such as varicose veins, phlebitis or circulatory edema. Hemorrhoids are a kind of varicose veins, which is why using extracts or supplements can help to treat this problem that many suffer in silence.

The active ingredients come from a group of chemicals called saponins. Escin is probably the most important one.

Escin helps to reduce the swelling and inflammation. The studies have concluded that escins seal leaks in the blood vessels. Moreover, they improve the elasticity of the veins, prevent the release of enzymes (known as glycosaminoglycan hydrolases) which break the collagen and produce holes in the capillary walls. In addition, they reduce the inflammation and block other physiological factors that damage the veins and our health.

The fruits are not edible due to the glycosides and saponins that they contain. This is due to the fact that they can trigger different digestive disorders and side effects. However, the non-toxic parts from this tree and plant (mostly the bark) are what is used to make dietary supplements.

Origin of the Horse Chestnut

Horse Chestnut Tree

It is a tree that belongs to the hippocastanaceae family and it can grow up to 30 meters high. It is native to the Balkans , north of India, Asia Minor, Greece, Bulgaria, the Caucasus and the Himalaya. History tells us that it was taken from Constantinople to France where it was planted in the streets of Paris. It can still be found there today and it has also been cultivated in areas with a warm climate, as well as in Northern areas of Europe and America.

The name ‘horse chestnut’ was coined by the Turks, who fed their horses with the fruit from this tree. They did this in order to provide energy for their animals during their long travels and hard works.

Precisely, the fruit of this plant is surrounded by a capsule with thorns that holds the seeds.

The first mention of these plants appears in a letter from 1557. However, it would not become widely known until the 19th century. This tree does not live for a very long time, and its wood is not useful for building, which is why it may have been underestimated in the past.

The first studies about the properties of this tree were performed in Germany in 1960. From then on, it became renowned for its properties as an anti-inflammatory elements for vein disorders on the legs.

Thanks to this, it is currently the third most sold natural product in Germany.

Fruit from Horse Chestnut

As we have previously said, the fruit from horse chestnut is not edible even if it has been consumed in the past. Today, it has been proven that the fruit, as well as the bark that surrounds it, are toxic due to its content in escin (saponin). It has a very bitter flavor, which is why most people refuse to it again after the first time.
