Where does the horse chestnut tree grow?

Horse chestnut grows mainly in Europe, Asia and the north of the American continent, such as in Canada or the United States.
Horse chestnut is native to western Asia, mainly Turkey. It was then introduced to Europe in the late 1500s.


– Horse chestnut is used in the treatment of heavy legs , however its effectiveness is questioned by some specialists due to the lack of conclusive studies, although the Cochrane (read below) meets these criticisms. You should also know that it is always difficult to prove the effectiveness of a remedy for sensations such as heavy or aching legs , an ailment that is also questioned. However, it may be possible to notice objective symptoms, such as the volume of the legs and the presence of edema.
Measures other than horse chestnut for sore legsmay include regular exercise (promoting blood circulation) and a healthy diet, especially one rich in fruits and vegetables. Discover our complete file on heavy or painful legs

study A 2012 study by Cochrane, an organization of scientists, showed horse chestnut seed extract to be an effective and safe short-term treatment for chronic venous insufficiency. Overall, this study showed an improvement in chronic venous insufficiency in terms of signs and symptoms (eg leg volume and presence of edema) with this horse chestnut extract compared to a placebo. This study was published on 14 November 2012 in the Cochrane Library (DOI: 10.1002/14651858.CD003230.pub4 ). Citing this study, as well as another one from 2015, larger than the one from 2012, also from Cochrane, and reaching the same conclusions, the journalists of a special edition of the French magazine Science & Viedated July 2020, dedicated to medicinal plants, estimated when talking about horse chestnut that its effectiveness against venous insufficiency has been scientifically proven. The journal Science & Vie also published a favorable review of red vine (Vitis vinifera) also against venous insufficiency.

– It is not possible to consume horse chestnut directly. In other words, horse chestnut must be made into medicine or preparation (eg cream). We must not confuse the Portuguese chestnut ( Castanea sativa ), which is edible, with the horse chestnut.

– When they ripen, the chestnuts change from green to brown.

– Horse chestnut, in the form of medicine, is widely used and appreciated in Germany. In this country, it is one of the most used medicinal plants, as well as ginkgo biloba and St. John’s wort (hypercoa) .
