Pei Pa Koa (Cantonese pronunciation) is a Chinese herbal syrup that's been around for more than 100 years, originating from Beijing during the Qing dynasty. The syrup is used to treat cough, phlegm, lungs, etc.
The recipe hasn't changed since it was conceived. And in 1946, the company “Nin Jiom” was established in Hong Kong and commercialized this product.
The syrup is an iconic staple in Chinese households, and the packaging is distinctly unique to its era.
