Balloonflower Root for Cough and Asthma Relief

Balloonflower Root (Platycodon grandiflorus Root, Jie Geng)

Overview:
Balloonflower root, known as Jie Geng in Traditional Chinese Medicine (TCM), is the dried root of Platycodon grandiflorus, a perennial herb native to East Asia. It has been used for centuries to support respiratory health, soothe the throat, and expel phlegm. Its distinctive guiding property helps direct the effects of other herbs to the upper body, especially the lungs and throat.

Botanical Profile:
Platycodon grandiflorus, also called balloonflower due to its balloon-like buds, produces thick, fleshy roots that are harvested in autumn. After cleaning and drying, the roots are used medicinally for both internal and external applications.

Traditional Uses in TCM:

1. Supports Lung Function:
   Jie Geng opens the lungs and helps relieve symptoms like coughing, chest congestion, and shortness of breath, particularly when due to phlegm.

2. Soothes the Throat:
   It is commonly used for sore throat, hoarseness, and laryngitis, often in formulas treating wind-heat or wind-cold conditions.

3. Clears Pus and Infections:
   Jie Geng is used to promote the discharge of pus in conditions such as lung abscesses or throat infections.

4. Guides Herbs Upward:
   A unique function of Jie Geng is its ability to "guide" other herbs to the upper body, enhancing their effect in the chest and throat.

Active Compounds and Effects:
Balloonflower root contains triterpenoid saponins (notably platycodin D), flavonoids, and polysaccharides. These compounds are associated with expectorant, anti-inflammatory, antimicrobial, and immune-supporting properties.

Usage and Dosage:

• Form: Often used as decoction, extract powder, capsules, or syrup.

• Dosage: Typically 3–9 grams per day when used as dried root in decoction.

Precautions:

• Avoid in cases of chronic cough due to yin deficiency, or when coughing blood.

• Use cautiously during pregnancy and consult a healthcare provider before use.

• May cause mild irritation to the throat or stomach in sensitive individuals if overused.
