Product Use

Production & Sourcing

The production of Dong Quai begins with cultivating the plant in well-drained, fertile soil, typically in cool, high-altitude regions where it thrives. The cultivation process involves sowing seeds or planting root divisions in fields, where the plants require careful management to ensure healthy growth over a period of three to four years before they reach maturity.
Harvesting Dong Quai is a meticulous process, usually carried out in the late autumn when the roots have accumulated their maximum beneficial compounds. The entire plant is dug up, but it is the thick, aromatic roots that are most valued. The roots are cleaned to remove soil and then sliced into pieces for drying. The drying process is crucial as it preserves the root’s active constituents. The dried roots are often further processed into powders, extracts, or sliced roots for various applications.
