Acute bronchitis
Also known as: acute bronchitis, chest cold, acute tracheobronchitis, acute cough associated with bronchial inflammation
Acute bronchitis is a short-term inflammation of the bronchi, most commonly associated with a viral respiratory infection. It typically presents with cough, with or without sputum, and may include chest discomfort, fatigue, sore throat, nasal symptoms or mild wheeze. In otherwise healthy people it is usually self-limiting, although the cough may persist for three to four weeks. Antibiotics are not routinely indicated for uncomplicated acute bronchitis. TCM management is based on differentiation of Wind-Cold, Wind-Heat, Phlegm-Heat, Cold-Phlegm or a lingering deficiency pattern and must not delay assessment for pneumonia, asthma, COPD exacerbation, influenza, COVID-19 or another serious respiratory disorder.

Lifestyle & Diet
- •Rest, maintain adequate hydration and use warm or soothing fluids according to tolerance.
- •Avoid smoking, second-hand smoke, vaping, dust, strong fragrances and other airway irritants.
- •Humidified air may provide symptomatic comfort, but equipment must be cleaned appropriately to prevent microbial contamination.
- •Honey may soothe cough in adults and children older than 12 months; never give honey to an infant younger than 12 months.
- •Avoid routine antibiotic expectations for uncomplicated acute bronchitis because most cases are viral.
- •Explain that the cough commonly lasts up to three or four weeks; reassess for deterioration or symptoms beyond the expected course.
- •Follow current respiratory-infection guidance regarding testing, staying home, masking and contact with vulnerable people when a transmissible infection is suspected.
- •Avoid strenuous exercise during fever or significant systemic illness and return gradually as breathing and energy normalise.
- •Do not use smoke-producing moxibustion in poorly ventilated spaces or around patients with reactive airway symptoms.
Cautions & Contraindications
- •Do not treat presumed acute bronchitis without referral when pneumonia or another serious cardiopulmonary disorder cannot be reasonably excluded.[,]
- •Do not advise patients to stop prescribed inhalers, antivirals, antibiotics or other medicines without consultation with the prescribing clinician.[,]
- •Do not assume yellow or green sputum alone proves bacterial infection or requires antibiotics.[,]
- •Avoid herbs containing restricted, toxic, improperly processed or legally prohibited substances.[]
- •Screen all herbal prescriptions for pregnancy, breastfeeding, paediatric age, allergy, hepatic or renal disease, hypertension, cardiovascular disease and herb–drug interactions.[]
- •Use extreme caution with or avoid Má Huáng-containing prescriptions in cardiovascular disease, uncontrolled hypertension, tachyarrhythmia, hyperthyroidism, stimulant sensitivity or interacting medicine use.[,]
- •Do not use raw Bàn Xià, raw Nán Xīng or non-compliant Xì Xīn products.[,]
- •Avoid strong warming formulas or moxibustion in Phlegm-Heat, high fever, pronounced thirst or a red tongue with yellow coating.[,]
- •Avoid strong tonification while an unresolved acute excess pathogen remains.[,]
- •Do not needle deeply over the thorax, lung fields or supraclavicular region.[]
- •CV22 Tiāntū requires specialised anatomical training and controlled insertion technique.[,]
- •Do not perform treatment that delays emergency care when respiratory distress, hypoxia, haemoptysis, confusion or severe chest pain is present.[,]
When to reassess or seek care again
- •Expect cough to settle over 3 weeks; reassess at 3 weeks if cough persists or at any point if it worsens.[]
- •Review within 48–72 hours if fever >38°C persists, breathlessness increases, or the patient becomes systemically unwell — consider pneumonia.[,]
- •Reassess in 6–8 weeks if cough persists beyond 8 weeks — investigate for post-infectious cough, asthma, pertussis, or malignancy (chest X-ray, spirometry).[]
- •Smoking, vaping, or ongoing environmental smoke/dust exposure.[]
- •Recurrent viral URTIs, cold exposure, and Wind invasion in constitutionally Lung-qi deficient patients.[]
- •Poorly controlled asthma, COPD, or gastro-oesophageal reflux triggering chronic cough.[]
Frequently Asked Questions
What are the main TCM patterns associated with acute bronchitis?+
Common patterns include Wind-Cold constraining the Lung, Wind-Heat invading the Lung, Phlegm-Heat obstructing the Lung, Cold-Phlegm obstructing the Lung and a lingering post-infectious cough involving Lung Qì or Lung Yīn deficiency [3].
Which acupuncture points are commonly considered for acute bronchitis?+
Frequently considered points include LU7, LU5, BL13, LI4, ST40 and CV17. Selection must follow the diagnosed pattern, respiratory status, constitution and relevant anatomical safety requirements [3].
How long does an uncomplicated acute-bronchitis cough usually last?+
The cough is commonly self-limiting but may persist for three to four weeks. Worsening symptoms, significant breathlessness, haemoptysis, persistent fever, recurrent bronchitis or cough lasting beyond three weeks should prompt medical review [1].
Are antibiotics normally required for acute bronchitis?+
Antibiotics are not routinely recommended for uncomplicated acute bronchitis because most cases are viral and antibiotics generally make little difference to the overall clinical course. Medical assessment determines whether a bacterial infection or high-risk presentation requires different management [1].
When should a patient with suspected acute bronchitis be referred urgently?+
Urgent referral is indicated for severe or worsening breathlessness, cyanosis, confusion, haemoptysis, severe chest pain, suspected pneumonia, persistent or very high fever, hypoxia or substantial clinical deterioration [1].
Can acupuncture and Chinese herbal medicine replace medical assessment?+
No. They may be used as adjunctive approaches by appropriately qualified practitioners, but they must not delay diagnosis or treatment of pneumonia, asthma or COPD exacerbation, influenza, COVID-19, pertussis, pulmonary embolism, cardiac disease or another serious cause of cough [3].
