For centuries, cultures across Asia, Africa, and South America have relied on Euphorbia hirta—a small leafy herb often called asthma weed—as a natural aid for breathing problems. In traditional medicine, it has been used to soothe coughs, ease asthma, and support lung health. While modern medicine does not endorse it as a cure, growing interest in herbal remedies has put this humble weed back in the spotlight, particularly for its potential role in lung cleansing and respiratory support.
This article explores Euphorbia hirta’s history, traditional uses, possible benefits for the lungs, and how it has been prepared in folk remedies.
What Is Euphorbia hirta?
- Botanical family: Euphorbiaceae
- Common names: Asthma weed, snake weed, tawa-tawa (Philippines)
- Appearance: A small, hairy-stemmed plant with oval leaves and tiny clustered flowers.
- Habitat: Commonly found in tropical and subtropical regions, often growing wild along roadsides and fields.
Traditional Uses for Lung Health
Asthma Support
The nickname asthma weed reflects its long use in folk medicine for easing wheezing, shortness of breath, and chest tightness. Decoctions were often prepared from the leaves and stems.
Coughs and Colds
Communities in Asia and Africa brewed Euphorbia hirta tea to loosen phlegm, relieve persistent coughs, and soothe irritated airways.
Bronchial Comfort
By reducing inflammation and promoting clearer airways, traditional practitioners used it as a natural lung cleanser, especially for those exposed to smoke or dust.
What Science Suggests
Research on Euphorbia hirta is still limited, but preliminary studies indicate:
- Anti-inflammatory effects: Certain compounds may reduce airway swelling.
- Antimicrobial activity: Extracts show action against some bacteria, which may help in preventing respiratory infections.
- Bronchodilator properties: Animal studies suggest it may help relax airway muscles, improving airflow.
However, most evidence comes from laboratory and animal studies. Human clinical trials are still scarce, so claims of lung cleansing must be taken cautiously.
How It’s Traditionally Prepared
- Herbal Tea/Decoction: Leaves and stems boiled in water for 10–15 minutes and consumed warm.
- Poultice: Crushed leaves applied externally for skin issues (less common for lung health).
- Powder: Dried leaves ground into powder and taken in small doses with water.
Safety and Precautions
- Euphorbia hirta contains latex that may cause skin or eye irritation.
- High doses may lead to nausea or stomach upset.
- Pregnant or breastfeeding women should avoid it due to insufficient safety data.
- People with chronic respiratory conditions like asthma or COPD should consult a doctor before use—never replace prescribed inhalers or treatments with herbal remedies.

Conclusion
Euphorbia hirta is a traditional herb with a long reputation for supporting lung health. Folk practices used it to ease asthma, clear phlegm, and cleanse the lungs from irritants. Early research shows promising anti-inflammatory and bronchodilator effects, but more human studies are needed to confirm its safety and effectiveness.
If you’re interested in lung health, Euphorbia hirta may serve as a complementary herbal option, but it should never replace professional medical care. Always consult your healthcare provider before trying new remedies, especially for respiratory issues.
