Platycodon grandiflorus
Pronounced Common: Jie Geng (jyeh-gung); Balloon Flower. Latin: Platycodon grandiflorus (pla-TEE-koh-don gran-dih-FLOR-us).
Neutral, drying, and dispersing: the messenger that opens a phlegm-bound chest, drains pus from the Lung, and floats other herbs upward.
No specific human safety studies. Platycodon is a food-homology plant (eaten as doraji) and is not on standard pregnancy-contraindicated (emmenagogue/abortifacient) lists; TCM regards culinary and standard therapeutic doses as generally acceptable. Some Western retail sources advise avoidance for lack of data. Prudent course: culinary amounts acceptable; avoid concentrated extracts and high therapeutic doses without practitioner supervision. (AHPA Botanical Safety Handbook, 2nd ed.; limited data.)
No documented lactation concerns; the root is a traditional food during and after pregnancy in Korea. No dedicated studies exist. Culinary use appears low-risk; use caution with concentrated preparations. (Limited data.)
Used in reduced-dose pediatric TCM cough and sore-throat formulas and eaten as food. Generally regarded as safe short-term at age-appropriate reduced doses for productive cough and sore throat. Avoid in infants and do not exceed standard dosing. Seek care for high fever, breathing difficulty, or cough lasting beyond a few weeks.
Large doses irritate the stomach and provoke nausea and vomiting (a saponin effect), so keep to standard dosing. May cause mild gastrointestinal upset. Saponins are hemolytic if injected: oral use only, never parenteral.
Avoid in yin-deficient dry cough and in coughing or spitting of blood from deficiency fire. Use cautiously with active peptic ulcer disease (saponin mucosal irritation). Not for intravenous or injectable use.
Widely cultivated across East Asia as food, medicine, and garden ornamental; abundant and not at-risk (not listed by United Plant Savers). Prefer cultivated root.
Not in canonical biblical or Mediterranean (Dioscorides/Pliny) texts; native to East Asia. First recorded in the Shennong Ben Cao Jing (Han dynasty). A culinary and medicinal staple across Korea (doraji), China (jiegeng), and Japan (kikyo).
