Overview

Jakseolcha ("sparrow-tongue tea") takes its name from its tiny, tongue-shaped young leaves, picked early for the finest grade. The Donguibogam lists it under the plain name "bitter tea" (苦茶) and records the same everyday effects tea drinkers still recognize: clearing the head, aiding digestion after a heavy meal, and keeping drowsiness at bay.

TranslationIts nature is slightly cold (some say cold), its taste sweet and bitter, and it is non-toxic. It lowers qi, resolves lingering food stagnation, clears the head and eyes, promotes urination, stops wasting-thirst, and reduces excessive sleepiness. It also counters the toxicity of grilled and fried foods.

Caution: The classics themselves caution that long-term use can be depleting and that tea taken cold tends to accumulate phlegm; best enjoyed warm and in moderation, and avoided close to bedtime given its wakefulness effect. Consult a professional.

Frequently asked questions

Is jakseolcha the same plant as ordinary green tea?

Yes — both come from Camellia sinensis. "Jakseolcha" refers to tea made from the earliest, tiny tongue-shaped leaf buds, prized as the finest grade.

Did the Donguibogam warn about drinking too much tea?

Yes — the text itself notes that long-term use can be depleting to the body and that cold tea tends to cause phlegm to accumulate, advising moderation.
