About Us
Guizhou Province, located in southwest China, is renowned as a world-class tourism destination. Its breathtaking natural landscapes, diverse mountain and water scenery, and vibrant ethnic culture have earned it the reputation of being a captivating “natural park.”
With its numerous mountain ranges, lofty peaks, and deep valleys, Guizhou boasts pristine air quality and a mild climate marked by distinct seasons, warm breezes in spring, and abundant rainfall. These exceptional geographical and climatic conditions make Guizhou an ideal habitat for Rosa roxburghii, a rare and precious plant. The province is affectionately known as the “Home of Rosa Roxburghii” in China.
Rosa roxburghii, commonly referred to as Youth Pear, belongs to the Rosaceae family. It thrives at altitudes of 500 to 2,500 meters, blooming in April and May and bearing fruit from August to October. The plant has two primary varieties: yellow rosa roxburghii and golden rosa roxburghii.
Yellow rosa roxburghii features pink blossoms and flattened, round fruits with yellow skin covered in dense spines. The flesh is white or yellow, and the fruit contains seeds.
Golden rosa roxburghii This variety has white blossoms and spindle-shaped fruits with yellow-brown spiny skin. The flesh is orange-yellow, seedless, and contains six times the sugar content of the yellow variety.
The medicinal properties of rosa roxburghii have been documented in the classic Chinese pharmacopeia Compendium of Materia Medica. In Guizhou’s folk traditions, wild rosa roxburghii fruits have been used to produce wine for over 400 years.
In the 1940s, Chinese biochemists and nutritionists discovered that rosa roxburghii fruit is exceptionally rich in vitamin C, recommending it as a new source of nutrition. Since the 1980s, Guizhou has undertaken efforts to protect wild rosa roxburghii resources and promote its cultivation. By the 1990s, the deep processing of rosa roxburghii fruit advanced significantly, leading to the development of mature products such as rosa roxburghii fruit juice, candied fruits, and freeze-dried powders. These products have since entered the consumer market, gaining popularity for their unique health benefits and beauty-enhancing properties.
