Primary processing of ginseng


Once the roots are harvested, the next step is to wash them. Since ginseng roots should always be washed when they are fresh, it is preferable to wash roots as soon as possible after harvest. The most important thing to keep in mind is not to over wash the roots. Too vigorous washing will damage the fragile "skin" of the root.

There are commercially available pieces of equipment specifically designed to wash ginseng roots, which typically consist of a barrel that is mechanically rotated as water jets spray the roots. Some mechanically inclined growers have even modified old wringer washers for washing roots.



It is important to regularly inspect roots throughout the drying process. Any discoloration or mold on the roots indicates a problem, suggesting the need for adjustments in the temperature, humidity, or airflow. As ginseng roots dry, they will begin to shrink, but often will remain spongy at least partway through the drying process. To determine if roots are completely dried, sample a few roots by breaking them. Properly dried roots snap easily into two pieces. Carefully inspect the inside of the root for any discoloration; a properly dried root should be entirely white inside. Drying too quickly will often create a brown ring inside the root, while drying too slowly will create moldy sections.



With recent progress and the large-scale development of the modern Chinese medicine industry, the production of raw materials must be standardized and updated to ensure the stability and reliability of the quantity and quality of raw materials. Similarly, the continuous development of the circulation of medicinal materials also requires standardized and stable production of medicinal materials as the basis for business development of enterprises. According to the development of Chinese traditional medicine processing industry, many enterprises try to enter the international mainstream market, and many foreign pharmaceutical enterprises also require the supply of standardized raw materials of Chinese medicine. All these require that the production of traditional Chinese medicine must be standardized and large-scale, that is, according to GAP (Good Agricultural Practice for Chinese Crude Drugsproduction of medicinal materials. China is a country with abundant and diverse resources and has a long medical culture. We should establish a complete standardization system in the research and development of traditional medicine, especially in the modernization of traditional Chinese medicine, to set a model for international traditional medicine.
