Supported by clinical research for acute bronchitis
Why it may be relevant
When bronchitis is showing up as a productive cough with mucus, this herb has been studied for that classic acute presentation in a pragmatic clinical trial.
Umckaloabo (Pelargonium sidoides extract EPs® 7630) is one of the better-studied herbs for acute bronchitis: pooled placebo-controlled trials suggest it may ease symptom severity and shorten how long a cough lingers, though a recent large pragmatic trial found no clear advantage over usual care, so results are encouraging but not uniform.
Dose or use Follow product labeling; consult a healthcare practitioner.
Key study Systematic review & meta-analysis (2008, PMID 18222667): Pelargonium sidoides for acute bronchitis pooled placebo/standard-controlled RCTs of mono-extract in acute bronchitis and found it may reduce symptom severity; note that a large 2026 pragmatic trial (PHYTOBRONCH, PMID 42014704) found no significant benefit over usual care, so the evidence is positive overall but mixed.
EvidenceSupported by controlled trialsTime to resultsTypically 1–2 weeks
Caution: Not recommended during pregnancy or breastfeeding without practitioner guidance; check with your doctor if you take blood-thinning medications.
Thins mucus so a congested cough clears more easily
Why it may be relevant
When your cough is wet and your chest feels full of mucus, NAC works as a mucolytic - it helps break down thick phlegm so it is easier to cough up.
NAC is a well-recognized mucolytic that raises glutathione and helps loosen thick phlegm. Pooled trials in chronic bronchitis show it can reduce flare-ups, and it is widely used to make a wet, congested cough easier to clear; the evidence is strongest for chronic bronchitis rather than short-lived acute episodes.
Dose or use Commonly taken as 600 mg one to two times daily with water. Follow product labeling and check with your practitioner.
Key study Meta-analysis (2024, PMID 38555190): N-acetylcysteine in COPD and chronic bronchitis/pre-COPD pooled RCTs and found NAC significantly reduced the incidence of exacerbations in chronic bronchitis/pre-COPD (IRR 0.81, 95% CI 0.69-0.95). The evidence is centered on chronic bronchitis, so its role in short-term acute bronchitis is supportive rather than proven.

Caution: May cause nausea or stomach upset. If you have asthma, introduce it cautiously; avoid combining with nitroglycerin, and check with your doctor if you take other medications.

Cineole-rich oil used as steam to ease congestion
Why it may be relevant
When congestion is the main problem, inhaling eucalyptus vapour can help open a stuffy chest and loosen mucus so you can breathe more easily.
Eucalyptus oil's active compound, cineole, has a decongestant and expectorant reputation, and its library entry lists bronchitis and congestion. We present it on that basis as a supportive, ungraded option.
Dose or use Add a few drops to a bowl of hot water and inhale the steam, or use a well-diluted chest rub. Do not swallow.
Key study Used by steam inhalation and topically for congestion and chesty coughs; this specific use in acute bronchitis has not been confirmed by a controlled clinical trial included in this review, so it is presented as ungraded.
EvidenceCenturies of traditional use · Human evidence not yet assessedTime to resultsOften eases congestion within minutes of inhalingTraditional useLong-standing traditional staple
Caution: Never take internally - eucalyptus oil is toxic if swallowed. Do not apply near the face of infants or young children, and dilute well before any skin use.

Herbal expectorant traditionally used for chesty coughs
Why it may be relevant
For a mucusy cough, thyme is a long-used expectorant - its thymol content is thought to help loosen phlegm and calm the urge to cough.
Thyme has a long history of traditional use for bronchitis and coughs, and its library entry names these directly. We present it on that traditional basis rather than as a clinically proven treatment.
Dose or use Commonly used as a warm tea (1-2 tsp dried thyme steeped in hot water) up to a few times a day, or per product labeling.
Key study Traditionally used, often combined with ivy, for productive bronchitis coughs; this specific use has not been confirmed by a controlled clinical trial included in this review, so it is presented as ungraded.
EvidenceCenturies of traditional use · Human evidence not yet assessedTime to resultsOften within a few days of regular useTraditional useLong-standing traditional staple
Caution: Avoid if you are allergic to thyme or other mint-family (Lamiaceae) plants. Use only food-level amounts during pregnancy and check with your practitioner before medicinal doses.

Caution: Not recommended during pregnancy or breastfeeding without practitioner guidance; check with your doctor if you take blood-thinning medications.
Traditionally used for viral respiratory infections
Why it may be relevant
Since a chesty bronchitis cough often starts with a virus, andrographis is used to ease the cough, sore throat and other upper-respiratory symptoms that come with it.
Andrographis has a long traditional use for cold, flu and respiratory-infection symptoms, and pooled trials in acute respiratory infections suggest it may ease cough and sore throat. That evidence is for respiratory infections broadly rather than bronchitis specifically, so we present it as a supportive option.
Dose or use Taken as a standardized extract capsule per product labeling; commonly used only during the acute phase.
Key study Systematic review & meta-analysis (2017, PMID 28783743): Andrographis paniculata for symptomatic relief of acute respiratory tract infections pooled 33 RCTs (7175 patients) and found it may improve cough and other ARTI symptoms; the evidence covers respiratory infections generally rather than bronchitis alone, so it is graded as indirect (C) for bronchitis.

Caution: Avoid during pregnancy and if trying to conceive. It may lower blood sugar and blood pressure and can occasionally cause stomach upset or allergic reactions - check with your practitioner if you take related medications.

Lung-meridian acupressure point for coughs
Why it may be relevant
If you would rather do something with your hands, LU7 is the main Lung-meridian acupressure point, traditionally used to ease coughs and chest symptoms - simple to press on yourself anytime.
In Traditional Chinese Medicine, LU7 is a classic point for coughs, colds and bronchitis, and its library entry names these directly. We present it on that traditional basis as a gentle, no-cost self-care technique.
Dose or use Find the point about one and a half finger-widths above the wrist crease on the thumb side. Press with firm, circular pressure for 1-2 minutes on each arm.

Soothing demulcent that coats a dry, irritated throat
Why it may be relevant
For a dry, tickly cough with little mucus, marshmallow root is a demulcent - its mucilage forms a soothing film over an irritated airway to calm the urge to cough.
Marshmallow root has centuries of traditional use for soothing sore, irritated throats and coughs, and its library entry names this use. We present it on that traditional basis rather than as a proven treatment.
Dose or use Commonly taken as a cold-water infusion or tea, or as lozenges or syrup, several times a day. Drink plenty of water with it.
