This is Bob Flaws' rendition of Po Sum On ® medicated Oil. In the early 1900s , 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.Functions Move the qi and quickens the blood, disperses inflammation and stops pain and itchingIngredients Bo He You (Peppermint oil - Oleum Menthae Piperitae) Xue Jie (Sanguis Draconis)Cha You (Tea oil (Oleum Camelliae Theae, Tea Oil, not tea tree oil) Huang Qin (Radix Scutellariae)Gui You (Cinnamon oil - Oleum Cinnamomi Cassiae) Gan Cao (Radix Glycyrrhizae)Method of Use Adults and children two years of age and older: Apply to affected area not more than 3-4 times daily.

These include peppermint oil, tea oil, cinnamon oil, and Xue Jie (Sanguis Draconis). Not only does tea oil provide therich smoothness of this medicated oil, the xanthines it contains are also very stimulating to the qi and blood. Peppermint oil, tea oil, and Huang Qin (Radix Scutellariae) are all cool or cold and clear heat. Cinnamon oil is warm and warms and frees the flow of the channels and vessels. The addition of cinnamon oil insures that the heat-clearing ingredients are not overly cold and, therefore, constricting, while the cool and cold ingredients insure that cinnamon oil does not aggravate heat with heat. Gan Cao (Radix Glycyrrhizae) enters all 12 channels and moderates and regulates the harsh qualities of the other herbs, whether hot or cold. When used topically, it also resolves toxins and emolliates and softens the skin. WARNINGS1. For external use only.2. Avoid contact with eyes and genitals.3.
