Xanthium refers to the fruits of Xanthium strumarium, the common cocklebur. Xanthium is from an ancient Greek word xanthos meaning yellow; strumarium means "cushionlike swelling," in reference to the seedpods which turn from green to yellow as they ripen (later they become deep yellow to brown). Cocklebur is a reference to the cockle shell-like appearance of the pods and their "burry" nature. The pods (fruit) are used in Chinese medicine and known as cangerzi. Cang is based on the character that means deep green; er means ear, this referring to the appearance of the leaves like green pig's ears (see photo, below); zi is the fruit.

The leaves and root are anodyne, antirheumatic, appetizer, diaphoretic, diuretic, emollient, laxative and sedative. The plant is considered to be useful in treating long-standing cases of malaria and is used as an adulterant for Datura stramonium. An infusion of the plant has been used in the treatment of rheumatism, diseased kidneys and tuberculosis. It has also been used as a liniment on the armpits to reduce perspiration. The fruits contain a number of medically active compounds including glycosides and phytosterols. They are anodyne, antibacterial, antifungal, antimalarial, antirheumatic, antispasmodic, antitussive, cytotxic, hypoglycaemic and stomachic. They are used internally in the treatment of allergic rhinitis, sinusitis, catarrh, rheumatism, rheumatoid arthritis, constipation, diarrhoea, lumbago, leprosy and pruritis. They are also used externally to treat pruritis. The fruits are harvested when ripe and dried for later use. The root is a bitter tonic and febrifuge. It has historically been used in the treatment of scrofulous tumours. A decoction of the root has been used in the treatment of high fevers and to help a woman expel the afterbirth. A decoction of the seeds has been used in the treatment of bladder complaints. A poultice of the powdered seed has been applied as a salve on open sores.
