In the southeastern coastal province of Zhejiang, China, lush forests of Eucommia ulmoides (hardy rubber tree) quietly weave a legend of nature and culture. As one of the world’s key native habitats for Eucommia ulmoides, Zhejiang is renowned for producing this valuable resource with "golden quality." From misty mountain ranges to modern industrial parks, Zhejiang has harnessed its unique natural endowments and wisdom to decode the "golden secret" of the Eucommia industry.

Today, with the increasing awareness of health, Eucommia extract is becoming a healthy choice for more and more people with its unique health value. As a company deeply engaged in the field of natural health, Sunsourcebio knows that quality is the lifeline of products. To this end, we have established a quality control system with 32 key indicators, using almost strict standards to ensure that every batch of Eucommia extract is trustworthy.

Eucommia ulmoides is a precious Chinese medicinal material and health food raw material. Its main active ingredients include eucommia gum, eucommia polysaccharides, chlorogenic acid, and aucubin. The content and quality of these ingredients directly determine the efficacy and market value of Eucommia ulmoides. The growth environment of Eucommia ulmoides, especially the climatic conditions, greatly affects the accumulation of its active ingredients.

As an important raw material for traditional Chinese medicine and modern functional food, the choice of harvesting season for Eucommia ulmoides directly affects the quality and efficacy of the product. Years of field observation and laboratory analysis have shown that there is a clear difference in chemical composition between new leaves sprouting in spring and mature leaves in autumn, and this difference determines their most suitable application direction.
