Cang Er Zi ( Xanthium sibiricum) ia also known as Chinese Cocklebur and is a traditional Chinese medicinal herb that benefits the nasal passage and dispels wind dampness.

The Xanthium Fruit is a medicinal herb from the flowering plant called Cocklebur (Xanthium) which is a member of the daisy family and is native to Asia and the Americas.  The spines and seeds of the cocklebur fruit contain a toxic chemical called carboxyatractyloside.  When Xanthium Fruit is prepared for medicinal use the spines are removed from the bur and often stir-fried to reduce the amount of carboxyatractyloside in the herb.
