Which description best matches Tu Si Zi quality?

• A. Hollow, brittle seeds; pale surface
• B. Thin seeds; white surface
• C. Full, hard, solid seeds; greyish-brown or yellowish surface
• D. Soft seeds; green surface

Answer: (C)

Tu Si Zi quality reflects mature, well-preserved seeds. The best description is full, hard, solid seeds with a greyish-brown or yellowish surface. This indicates the seeds are dry and intact, ready to provide the intended astringent effect that helps stabilize essence and support kidney function. Hollow or pale seeds suggest deterioration or poor quality, thin seeds imply underdeveloped seeds, and soft seeds with a green surface indicate immaturity or spoilage. Therefore, full, hard, solid seeds with a greyish-brown or yellowish surface best matches Tu Si Zi.
