Which cross-section description correctly describes Tian Ma for good quality?

• A. Cross section should be chalky and opaque
• B. Cross section should be shiny and translucent but not horny
• C. Cross section should be horny, shiny, and translucent
• D. Cross section should be dull and grainy

Answer: (C)

When evaluating Tian Ma, the cross-section that signals good quality shows a horny, shiny, and translucent appearance. The “horny” texture means the tissue is dense and firm, indicating proper drying and intact structure. A shiny cross-section reflects good post-harvest drying, and translucence indicates the parenchyma is well preserved without excessive air spaces or breakdown. Chalky and opaque would suggest degradation or improper storage, while being dull and grainy suggests damage or contamination. A cross-section that is shiny and translucent but not horny is less ideal because the tissue isn’t as dense and robust as it should be. So, the combination of horny, shiny, and translucent best describes high-quality Tian Ma.
