CHING WAN HUNG
Ching Wan Hung (also written Jing Wan Hong) is a Chinese herbal ointment that is considered especially helpful in the treatment of burns. It has been applied to chemical burns, radiation burns, and sunburns, as well as burns caused by fire, electricity, steam, or direct contact with a hot liquid. It is also utilized to treat hemorrhoids, poison oak/ivy dermatitis, and bedsores. It acts to relieve pain, decrease inflammation and infection, and aid in the regeneration of the damaged tissues. It is fast acting, alleviating burn pain almost immediately after application. Rub a generous amount of ointment directly into the affected area after it has been thoroughly cleaned. The area may be covered with gauze to further reduce possibility of infection and irritation. Gauze should be changed daily. Note that this ointment, like many Chinese ointments and liniments with a red color, can stain clothing.

Other ingredients mentioned in Chinese literature about this product include rhubarb and gardenia. The red color of the ointment comes from several of the herbs, hence the name "Wan Hung" (meaning myriad red ingredients; Ching means capital, referring to the origin of the formula in a capital city).

It is used to treat ulcerations and rashes, and is a common remedy for dermatitis caused by contact with poison oak and similar allergens.
