White Flower Analgesic Balm is known throughout the world. The product was developed in 1927 by Gan Geog Eng, a resident of Singapore. The fluid was originally made only for private use, but family friends and acquaintances tried it out and liked it so much they convinced Mr. Gan to produce it on a commercial basis. He called it Pak Fah Yeow (also written Bai Hua You, which means white flower oil), named for his favorite flower, the white narcissus. The trademark was registered in 1935. Following the initial success in Singapore and Penang, Mr. Gan decided to enter into the Hong Kong market in 1951, seeing it as both a potential major market and ideal manufacturing center. With a series of marketing campaigns, extensive outdoor advertising, and endorsement by well-known Chinese opera actors, White Flower Oil became a leading product in the Far East. White Flower Analgesic Balm is manufactured by Hoe Hin Pak Fah Yeow Manufactory Limited, Hong Kong under strict quality control and GMP compliance.
