Po Sum On-保心安
In the early 20th century, over-the-counter Chinese or Western medicine was scarce. When ailments struck, the only solution was to get medicine prescribed by a herbalist from a herbal medicine shop. Then came the labourious process of preparing the remedy at home. To sufferers of minor complaints like colds and coughs, dizziness and abdominal pain, this practice was both expensive and time consuming. Appreciating this need, Mr. Kwok Chu Nam, an expert of Chinese medicine, developed a medicated oil for external use with a fine blend of medicinal herbs. He named it Po Sum On Medicated Oil -- an oil to assure well being of the whole family. Friends and relatives were given this new product to try it out. When its effects were further proven, the product was registered and officially marketed in Hong Kong in 1907.
