Thesis
The key words in “神农《食经》“茶茗久服令人有力悦志”” are not ornament. They mark where Tang tea names, vessels and provenance meet.
Text
“Shennong’s Classic of Food says: ‘Long use of cha and ming makes a person strong and gladens the spirit.’”
Context
托名神农的《食经》认为，长期饮茶能使人有力气、心情愉悦。
Evidence
- Collation: "令人有力、悦志"各本一致；《食经》为托名古书，今已亡佚，赖《茶经》引文得存一鳞。
- Existing readings: 吴觉农评此条为茶"悦志"功效的最早记载：现代研究表明茶中咖啡因与茶氨酸协同，确有提神而安神之效——与"有力悦志"暗合。
Analysis
The annotation matters less as philology than as a distinction between name and thing. "令人有力、悦志"各本一致；《食经》为托名古书，今已亡佚，赖《茶经》引文得存一鳞。 Once names settle, picking, grading and trade can share a language.
Conclusion
The section does not give a universal rule. It demonstrates a method: read the text, the annotation and the Tang context together before making a modern claim.
