11 Health Benefits of Horse Chestnut

Treats Varicose Veins:

These swollen veins are caused by CVI and typically occur in the legs. Horse chestnut extract improves the blood flow in your legs, thereby improving the venous tone. It also helps to decrease the swelling and pain associated with varicose veins.

Relieves Hemorrhoids:

The swollen veins around your anus and rectum are what we refer to as, hemorrhoids. Itching, irritation, rectal bleeding and feeling uncomfortable are all symptoms of hemorrhoids. However, these symptoms can be relieved with the help of horse chestnut seed extract by reducing the inflammation and swelling in the affected veins and that is mainly due to the anti-inflammatory properties of the same.

Has Antioxidant Properties:

Being rich in flavonoid compounds, including quercetin and kaempferol, horse chestnut seed extract has potent antioxidant properties. these compounds can help to prevent cell damage caused by unstable molecules called free radicals. Although both aescin and horse chestnut seed extract have antioxidant properties the effect of horse chestnut seed extract is greater than that of aescin alone.

Consists of Cancer-Fighting Compounds:

As per the studies, aescin helps to reduce tumor cell growth in certain cancers including leukemia, liver cancer, and multiple myeloma. aescin has also been observed to cause cell death in cancerous cells like lung cancer and pancreatic cancer. But it is to be noticed that all these studies focused on the use of aescin. There is still no clear evidence if horse chestnut seed extract would have the same effects.

Protects the Skin:

Horse chestnut seed extract has been linked to anti-aging effects as it reduces inflammation and protects cells. Horse chestnut is thus also made use of in cosmetics.


Helps with Male Fertility:

Aescin is a compound found in horse chestnut. The swelling of the veins near the testicles is one of the main causes of male infertility. The most effective treatment for infertility is thus aescin that consists of the anti-inflammatory and anti-swelling properties. As per a study, taking 30 mg of aescin every 12 hours improved sperm density, sperm motility, and sperm quality.

Relieves Symptoms of Chronic Venous Insufficiency:

This health condition is characterized by poor blood flow to the veins of the legs. Some of the symptoms are:

  • Weakness in the legs
  • Itchy legs
  • Edema, or swelling
  • Leg pain or cramps
  • Leg ulcers
  • Varicose veins or twisted veins that occur in legs

Compression therapy is considered to be one of the effective treatments that can help increase blood flow to the legs. As per a study, horse chestnut extract was also equally effective as compression therapy at reducing swelling and leg volume. however, there is still more research needed to determine the long-term effects.

Protects the Kidneys in Diabetes:

Kidneys can be damaged by diabetic complications.

In diabetic rats with kidney damage, horse chestnut seed extract helped in reducing inflammation ad markers of kidney damage.

May Fight Infections:

In a cell study, it was found that caffeic acid in horse chestnut killed bacteria.


Improves Gut Health:

Aescin blocks the effects of serotonin that is an important neurotransmitter in the gut.

In mice, aescin decreased inflammation and increased gut flow.

Has Potent Anti-inflammatory Properties:

A component found in horse chestnut seed extract, Aescin consists of anti-inflammatory properties that help to reduce inflammation that may be related to venous insufficiency, injury, and swelling. A typical ointment containing aescin can also be applied directly to reduce inflammation and swelling after trauma, sports injuries and surgery.
