Reading the bitterness

Ilex latifolia Thunb is a holly-family plant known in Japanese as Tarayō. A review lists it alongside the related species Ilex kudingcha as a source plant for large-leaved kudingcha drunk in China.

The same review introduces 『同君録』 (in translation: "Tong Jun Lu, Record of Tong Jun"), a book from the Later Han period (25-225 CE), as recording kudingcha as a bitter drink. It says that later investigation identified the originally described species as Ilex latifolia, Ilex kudingcha, and Ilex cortia. The review adds that I. cortia, which differs in botanical characteristics and chemical constituents, is now distinguished from kudingcha as a separate species (Gougucha). The description in 『同君録』 (in translation: "Tong Jun Lu, Record of Tong Jun") is introduced through the review; the original text itself was not checked.

Culture (1)

Ilex latifolia is documented as having bitternesspreliminary

Scope: Layer: literature (a review's secondhand account of an ancient text).

"In the book 'Tong Jun Lu' (A.D. 25-225; E. Han Dynasty), Kudingcha was described as having a bitter flavor and reportedly kept people awake all night. The original species in 'Tong Jun Lu' were investigated and certified to be I. latifolia, I. kudingcha, and I. cortia."
Limitations: The original 『同君録』 (in translation: "Tong Jun Lu, Record of Tong Jun") could not be checked (a secondhand account in the review). The review adds that I. cortia is now classified separately from kudingcha as Gougucha because its botanical characteristics, chemical constituents, and medicinal uses differ.
