Thesis

Section 12 is not really about “设服荠苨使六疾不瘳知人参为累则茶累尽矣”; it is about how Lu Yu turns tea from a local product into an object of argument.

Text

“If one takes qini in place of ginseng, none of the six ailments will be cured. Understand how ginseng may mislead, and the pitfalls of tea become clear.”

Context

荠苨（jì nǐ）：桔梗科植物，形似人参而性味不同，误服无效。六疾：泛指各种疾病。瘳（chōu）：痊愈。

Evidence

• Collation: "荠苨"各本一致，指形似人参而药性迥异的植物。吴觉农校注：此句收束全章，以"茶累尽矣"点明茶亦须辨真伪、得正法。
• Existing readings: 吴觉农评"知人参为累，则茶累尽矣"为全章结穴：辨茶如辨药，须识真伪、讲时地、重制法——此"知累而避"的态度，正是《茶经》教人科学饮茶的落脚处。

Analysis

Formally, the section gives a judgment, adds material detail, then returns to human practice. 荠苨（jì nǐ）：桔梗科植物，形似人参而性味不同，误服无效。六疾：泛指各种疾病。瘳（chōu）：痊愈。 That is why the Classic of Tea reads as an argued book rather than a miscellany.

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 I · The Origin, section 12; the original is in the public domain.

In Tang context, 吴觉农评"知人参为累，则茶累尽矣"为全章结穴：辨茶如辨药，须识真伪、讲时地、重制法——此"知累而避"的态度，正是《茶经》教人科学饮茶的落脚处。. Tea was tribute, medicine and monastery drink at once, not a standalone commodity; the conclusion cannot be transferred without that context.

Modern tea science would split the sentence into cultivar, soil, light and plucking variables. 吴觉农评"知人参为累，则茶累尽矣"为全章结穴：辨茶如辨药，须识真伪、讲时地、重制法——此"知累而避"的态度，正是《茶经》教人科学饮茶的落脚处。 The variables remain useful, but none of them alone explains the cup.

Storage adds another variable: moisture and temperature. "荠苨"各本一致，指形似人参而药性迥异的植物。吴觉农校注：此句收束全章，以"茶累尽矣"点明茶亦须辨真伪、得正法。 Old and young tea do not share one shelf life, so “the older the better” is not a rule.
