• C. Dry, full rhizomes with a hard texture; no fibrous roots or soil on the surface; yellow cross section
• D. Fresh rhizomes with water on surface; white cross section

Answer: (C)

Quality indicators for She Gan focus on proper drying, intactness, cleanliness, and internal color. A good quality She Gan is a dry, full rhizome with a hard texture, showing it has been properly dried and aged and is still structurally intact. It should be clean with no fibrous roots attached and no soil on the surface, which reflects thorough cleaning and good harvest handling. The cross-section should be yellow, indicating the normal internal coloration of a well-preserved dried rhizome. Fresh, wet, or soft specimens, or ones with surface soil or fibrous roots, point to poorer quality or improper processing.
