Platycodon Root
- Chinese
- 桔梗
- Pinyin
- Jie Geng
- Latin
- Radix Platycodi
Known in TCM as Jie Geng (桔梗), this bitter and acrid, neutral herb enters the Lung and Stomach. Traditionally, it opens and disseminates Lung Qi while transforming phlegm, used for cough, wheezing, chest oppression, and copious sputum in both wind-cold and wind-heat patterns that obstruct the Lung, most often applied for cough, productive cough, and pharyngitis. Modern research has identified Platycodin among its active constituents.

Traditional Use
Primary Actions
- Opens and disseminates Lung Qi while transforming phlegm, used for cough, wheezing, chest oppression, and copious sputum in both wind-cold and wind-heat patterns that obstruct the Lung.
- Benefits the throat and restores the voice, making it classically important for sore throat, hoarseness, painful swallowing, and loss of voice when phlegm, wind-heat, or toxicity blocks the throat gate.
- Expels pus and opens the Lung, so it is chosen for Lung abscess, throat suppuration, and toxic phlegm-heat with chest pain, fever, foul sputum, or blood-streaked expectoration.
- Guides the actions of other herbs upward to the chest and throat, which explains its frequent use in formulas that need upper-burner direction.
Secondary Actions
- IDENTITY NOTE: this record is therapeutically the same medicinal as balloonflower-root.json. The duplicate exists because the import split the common English name from the botanical-derived English name.
- Jie Geng is a medicine-food root in East Asia, but its upward-directing action remains clinically important and should not be overlooked.
Classic Formulas
- Zhi Sou San, where Jie Geng opens Lung Qi and helps stop lingering cough with phlegm after an external pathogen has not fully resolved.
- Yin Qiao San, using Jie Geng to benefit the throat and ventilate the Lung in wind-heat sore throat and early febrile disease.
- Pu Ji Xiao Du Yin, where Jie Geng helps direct toxin-clearing herbs to the upper burner and swollen painful throat.
Classical References
- Traditional materia medica records Jie Geng for chest fullness, throat obstruction, cough, and impaired Lung diffusion and descent.
- Its upward-guiding ability is a major classical reason it appears in both respiratory formulas and throat formulas.
- This file should stay clinically aligned with balloonflower-root.json unless the site intentionally decides to keep duplicate English-name records distinct for some future editorial reason.

Safety & Interactions
Contraindications
- Chronic cough due to Yin deficiency
- Coughing or spitting blood due to Yin-deficient fire
- Upward-rebellious Stomach Qi with significant nausea or vomiting
Cautions
- Excess dosage can cause nausea, vomiting, gastric irritation, sweating, or restlessness because of the herb's ascending and saponin-rich nature.
- Intravenous or parenteral use is contraindicated because platycodon saponins have hemolytic activity outside the digestive tract.
