Unfortunately, viruses and bacteria remain major causes of serious illness and thousands of deaths each year. In many cases, antibiotics are not the complete solution, especially when infections are viral or when resistance is involved. For that reason, many people also look to natural remedies for lung health that can support breathing and comfort—particularly herbs traditionally used for congestion, cough, and respiratory irritation.
Below is a practical guide to 15 of the best herbs for healthy lungs, including well-known botanicals used to help clear mucus, soothe inflamed airways, and support the body’s natural defenses.
The Best Herbs for Healthy Lungs
1) Cannabis
Research has explored cannabis for a range of potential benefits, including anti-cancer activity linked to cannabinoid-related pathways. When vaporized (rather than smoked), its active compounds may help support the body’s natural immune response and may reduce the spread of certain infections. Many users also report that vaporized cannabis can open the lungs and sinuses, similar to the effect of a bronchodilator, which is why it is sometimes discussed in relation to asthma management.
2) Peppermint
Peppermint and peppermint oil are rich in menthol, a compound known for relaxing muscles in the respiratory tract and promoting easier, freer breathing. Menthol also works as a helpful decongestant, and peppermint’s natural antioxidant properties may support the body in defending against harmful organisms.
3) Plantain
Plantain leaf has a long history of use for cough relief and for calming irritated mucous membranes. Its active components are associated with antibacterial, antimicrobial, anti-inflammatory, and antitoxic actions. Clinical research has also examined its value for colds, lung irritation, and persistent coughing, including support for mucus production when a dry cough is present.
4) Sage
Sage (especially sage essential oil) is traditionally used for sore throat and cough. Inhaling the steam from sage tea is a common folk method for easing sinus discomfort and supporting people dealing with respiratory complaints.
5) Thyme
Thyme is widely recognized for helping with chest congestion and is also known for its strong antimicrobial qualities. It has been used to help combat bacteria and viruses, making it a traditional choice for respiratory tract infections and even discussions around bacterial issues such as pneumonia.
6) Osha
Native to the Rocky Mountain region, osha root has been used in Native American traditions to support the respiratory system. It contains camphor-like compounds that are commonly associated with helping the lungs function well and supporting clearer breathing.
7) Oregano
Oregano contains natural compounds often described as decongestants and histamine reducers, which can positively affect the nasal passages and respiratory tract. Oregano essential oil has also been studied for its antimicrobial activity, including findings suggesting strong effects against staphylococcus aureus compared to certain antibiotic approaches.
8) Mullein
Mullein leaves and flowers are frequently used to make extracts that may support lung strength. Traditionally, mullein is used to:
- Help loosen and remove mucus
- Support cleansing of the bronchial tubes
- Calm lower respiratory inflammation
It can be taken as a tea or in tincture form.
9) Lungwort
Often found as a tree-growing lichen, lungwort has been used since the 1600s for respiratory wellness and congestion support. It contains compounds believed to encourage the body’s efforts to remove organisms that can negatively affect the lungs and airways.
10) Lobelia
Lobelia is sometimes described as one of the strongest traditional herbal options for respiratory support. It contains lobeline, an alkaloid studied for effects that include:
- Helping thin mucus and break up congestion
- Supporting easier breathing by encouraging airway relaxation
- Stimulating adrenal activity linked to epinephrine release
Because of its traditional use for cough and congestion, lobelia extracts have been included in some commercial cold and cough remedies.
11) Licorice
Licorice root is among the most widely used herbs globally. In traditional Chinese medicine, it is valued for soothing the mucous membranes of the throat, lungs, and stomach and for supporting detoxification of irritated tissue. Licorice is also used to:
- Calm an irritated throat
- Soften phlegm so it can be expelled more easily
- Reduce bronchial spasms
- Help counter oxidative stress that can inflame and tighten airways
Some sources also discuss licorice in the context of supporting the body’s defenses against abnormal cell growth in the lungs.
12) Eucalyptus
For generations, many cultures—including Australian Aboriginal traditions—have used eucalyptus aroma to support the respiratory system and ease throat irritation. It’s a common ingredient in cough products because cineole (a key eucalyptus compound) may:
- Reduce coughing
- Help break up congestion
- Soothe irritated sinuses
13) Elecampane
Elecampane has a long tradition of use for clearing excess mucus. It is often mentioned as helpful for people prone to bronchitis and recurring lung infections, supporting more comfortable breathing and easier expectoration.
14) Coltsfoot
Used for thousands of years in traditional practices, coltsfoot is still taken today to help:
- Expel surplus mucus from the lungs and bronchial tubes
- Ease symptoms linked with asthma, coughing, and bronchitis
15) Chaparral
Native to the American Southwest, chaparral has a history of use for lung cleansing. It contains potent antioxidants that may help reduce irritation. It also includes NDGA, a compound discussed for supporting a balanced histamine response and for its studied effects related to limiting the energy production of certain cancer cells.
