Where does sea buckthorn come from and how did its cultivation become professionalized?

Sea buckthorn ( Hippophae rhamnoides ) is a shrub with ancient origins , dating back to the end of the Ice Age . Native to the high plateaus of Asia , particularly Tibet and the Altai steppes , this plant gradually spread across Europe , the countries of the former Soviet Union and Canada over the centuries.

The earliest uses of sea buckthorn are documented in traditional Tibetan medicine , where it was used as a tonic and to treat various respiratory , gynecological , digestive , and skin conditions. Its use later spread to other traditional medicines , notably in ancient Greece , where Pliny the Elder mentioned it.

The history of sea buckthorn is closely linked to its botanical name " Hippophae rhamnoides ", which means "tree that makes horses shine" . This name comes from the belief that adding sea buckthorn leaves to horses' feed improved their coats , a practice attributed to Genghis Khan , founder of the Mongol Empire .

In Europe , sea buckthorn has naturally established itself on the coastal dunes of the Baltic Sea , in Germany , Poland , Holland , Finland and Latvia . In France and Italy , it is found mainly in mountainous regions such as the Alps and the Pyrenees , as well as on the edges of sandy lakes and rivers.

The introduction of sea buckthorn to North America is relatively recent. In Canada , the first plants were imported from Russia in the late 1930s , initially for ornamental purposes. It was only in the 1990s that commercial cultivation of sea buckthorn began to develop, particularly in Western Canada .

In Quebec , the first sea buckthorn plantation was established in 1998 on Île-d'Orléans . Since then, cultivation has gradually expanded in the province, growing from approximately 30 hectares in 2007 to an estimated 80+ hectares in 2015 .

The evolution of sea buckthorn cultivation has been marked by research and varietal selection efforts, particularly in Russia , China , Germany , Latvia and Scandinavia . This work has made it possible to develop commercial cultivars adapted to different climatic conditions and meeting the specific needs of the food and cosmetics industries.

Today, sea buckthorn is cultivated in many countries for its nutritional and medicinal properties . China has become the world's largest producer , with more than 1.33 million hectares converted into sea buckthorn groves since 1982. This expansion reflects the growing interest in this plant with its many virtues , whose thousand-year-old history continues to be written around the world.
