Euphorbia hirta is a small tropical medicinal herb used for centuries in traditional medicine across Asia, Africa, and the Americas. It grows in warm climates and is known for its hairy stems, reddish color, and milky sap.

It belongs to the Euphorbiaceae family and grows 15–50 cm tall in disturbed soils like roadsides, fields, and gardens. The plant has opposite leaves with serrated edges and releases a white latex when broken.

It contains many bioactive compounds such as flavonoids, tannins, alkaloids, terpenoids, saponins, phenolics, and steroids. These natural substances are believed to contribute to its traditional medicinal effects and have attracted scientific interest in recent studies.

One of its most common traditional uses is for respiratory problems. It has been used for asthma, cough, bronchitis, wheezing, and chest congestion. Herbal teas made from leaves are believed to help relax airways, reduce mucus, and ease breathing.

It is also used for digestive and urinary issues. Traditionally it helps with diarrhea, dysentery, stomach cramps, indigestion, and urinary tract support. It is considered a mild diuretic that may help increase urine flow and remove excess fluids from the body.

The plant is applied externally for skin problems such as wounds, rashes, insect bites, boils, and infections. It has also been used for fever management and sometimes for intestinal parasites. Poultices and crushed leaves are common traditional applications.

Common preparations include herbal teas, decoctions, powders, and poultices. However, caution is needed because excessive use may cause nausea, vomiting, or irritation. The sap can irritate skin and eyes, so proper care and moderation are important.

Overall, Euphorbia hirta remains an important traditional remedy in many rural communities due to its wide availability and long history of use. While valued in folk medicine, it should be used responsibly and with awareness of possible side effects.
