This is Bob Flaw's rendition of Po Sum On (Bao Xin An) Medicated Oil which was first introduced in 1907. In the early 1900's, Kwok Chu-nam, an expert in Chinese medicine, developed a medicated oil for external use with a blend of Chinese medicinal herbs. He named it Po Sum On, "Protect the Heart" Medicated Oil. As the story goes, friends and relatives were given this new product to try. When its effects were further proven, the product was officially marketed in Hong Kong and, from there, throughout East Asia. With a proven healing power for all sorts of complaints and supported by word-of-mouth, Po Sum On eventually became a household name in the Far East. Now this oil is available in an American version. It is still made with the same high quality ingredients but according to Western standards of manufacturing and packaging at a significantly lower price.
