Er Cha (Catechu)
Chinese Herb: Er Cha (Catechu, black Catechu)
Acacia Catechu; Catechu
Translated literally as "Child's Tea", Catechu appears in the classical Qi Li San Bruise Relieving Powder, and inadvertently in some Wing Chun dit da jow recipes.
Used topically, Catechu is bitter and astringent, exhibits a cool energy, and enters only the Lung meridian. Primarily a damp-draining herb, this substance aids in the generation of flesh and can aid in the arrest of bleeding, especially when caused by heat. It is for these reasons that has been used for athletic injuries.
