What is the typical surface color of Tu Si Zi seeds?

• A. Bright red
• B. Green
• C. Greyish-brown or yellowish surface
• D. White

Answer: (C)

The main idea here is identifying Tu Si Zi by its appearance, specifically the seed’s surface color. Tu Si Zi are the dried seeds of Cuscuta chinensis (dodder). They characteristically have a greyish-brown or yellowish surface after drying. This color fits the typical look of the dried seed coat and helps distinguish them from seeds or materials that might appear bright red, green, or white, which are not characteristic for Tu Si Zi. Minor variations can occur with storage or processing, but greyish-brown to yellowish remains the standard appearance.
