Thesis

Read through modern tea science, “神农《食经》“茶茗久服令人有力悦志”” is not a lab result but a set of variables: cultivar, soil, light and plucking standard.

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

Modern tea science would split “神农《食经》“茶茗久服令人有力悦志”” into cultivar, soil, light and plucking variables. 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。 They remain testable, but only with their conditions attached.

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.

Source: The Classic of Tea, Chapter VII · The History, section 2; the original is in the public domain.

The vessel is not background. 托名神农的《食经》认为，长期饮茶能使人有力气、心情愉悦。 The same leaf in a different bowl, grinder or sieve changes aroma and texture; vessel and tea are defined together.

Water and fire magnify the difference. The same leaf at a higher temperature or a longer steep changes the sweet-bitter balance; the text only becomes operational at the brewing stage.

In Tang context, 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。. Tea was tribute, medicine and monastery drink at once, not a standalone commodity; the conclusion cannot be transferred without that context.
