Euphorbia hirta, commonly known as asthma weed, is a small but powerful medicinal plant valued for centuries across various traditional healing systems.

Indigenous to tropical regions, it grows abundantly in Asia, Africa, and South America, where it has long been recognized for its wide range of therapeutic applications. The plant is particularly famous for its ability to ease respiratory problems, most notably asthma, bronchitis, and chronic cough.

Its natural compounds, such as flavonoids and tannins, work to relax the bronchi and airways, making breathing easier and reducing the severity of coughing fits. Because of these effects, it has earned a reputation as an accessible and effective herbal remedy for people suffering from respiratory distress in communities with limited access to modern medicine.
