History
The formula for Pei Pa Koa was originally created by Doctor Ip Tin-See, a physician for the Qing Dynasty. Yang Xiao-Lian, a provincial commander, asked Doctor Ip to treat his mother's persistent cough. They were so impressed that they created a factory to mass-produce it. Later, the Yang family sold the business to Tse Sui-Bong, a medicine practitioner. Nin Jiom Medicine Manufacturing was incorporated in 1962 to expand the business.

Today, Pei Pa Koa has annual sales of 45 million USD.
