What Traditional Chinese Medicine (TCM) herbs are used to suppress coughing and resolve phlegm?

Cold is the most common illness. Aside from nasal congestion—which can be particularly bothersome—coughing is another frequent symptom. Traditional Chinese medicine (TCM) offers numerous herbs effective for relieving cough and resolving phlegm, with notable therapeutic results. So, which TCM herbs are used for cough suppression and phlegm resolution? Let’s explore them below.

Common TCM Herbs for Cough Relief and Phlegm Resolution

1. Platycodon Root (Jiegeng)

Platycodon root is neutral in nature and bitter and pungent in taste. It functions to open and regulate lung qi, resolve phlegm, and drain pus. It is commonly used for wind-cold exterior syndromes, sore throat and swelling, lung abscess, cough with purulent sputum or blood, and abdominal pain with phlegm-damp accumulation.

2. Fritillaria Bulb (Chuanbeimu)

Fritillaria bulb is cool in nature and sweet and bitter in taste. It relieves cough, resolves phlegm, clears heat, and disperses nodules. It is indicated for chronic cough due to deficiency, hemoptysis, chest tightness and emotional depression, throat obstruction, lung atrophy (a TCM pattern of chronic lung weakness), scrofula, and breast abscess.

3. Aristolochia Fruit (Mandouling)

Aristolochia fruit is cold in nature and bitter with a slight pungency. It clears lung heat, resolves phlegm, suppresses cough, and alleviates wheezing. It is suitable for cough and wheezing due to lung-heat, copious phlegm with shortness of breath, chronic cough due to lung deficiency, hemoptysis, aphonia, and hemorrhoidal or fistulous swellings and pain.

4. Pinellia Rhizome (Banxia)

Pinellia rhizome is warm in nature and pungent in taste, and is toxic when used raw. It dries dampness and resolves phlegm, reverses upward qi movement to stop nausea and vomiting, and disperses nodules and dissipates stagnation. It is indicated for cough with rebellious qi, excessive phlegm obstructing the lungs, chest and epigastric fullness and distension, distending pain, and goiter, scrofula, or abscesses.

5. Peucedanum Root (Qianhu)

Peucedanum root is cool in nature and bitter and pungent in taste. It dispels wind, clears heat, descends lung qi, and resolves phlegm. It is used for wind-heat headache, cough and wheezing due to phlegm-heat, nausea and vomiting, and chest and diaphragmatic fullness and oppression.

The above lists common TCM herbs used for cough relief and phlegm resolution. These herbs all demonstrate excellent effects in moistening the lungs and suppressing cough. You may select an appropriate herb based on your specific condition; however, dosage and administration must be carefully observed—and consultation with a qualified TCM practitioner is strongly recommended. Additionally, for everyday cough with excessive phlegm, consuming pears may be beneficial: they not only supply vitamins but also help moisten the lungs and promote fluid production.
