King-to Nin Jiom Pei Pa Koa (), commonly known as Nin Jiom Pei Pa Koa or simply Nin Jiom Herbal Cough Syrup, is a Chinese patent medicine used for the relief of sore throat, coughs, hoarseness and aphonia. It is a throat demulcent and expectorant.
The brand diversified to also produce a number of other Chinese patent medicines such as Sho-saiko-to and Siwu Tang in 1993. It started producing throat lozenges in 1997 based on the original syrup. A sugar-free version of the original syrup was released in 2025.
Name The name is in Cantonese. In the name of the company, king-to () means "capital", referring to Beijing, and nin jiom () means "in memory of my mother"; hence, it stresses the important virtue of filial piety. In Pei Pa Koa, pei pa () is Cantonese for "loquat", while koa () means "syrup", though it is unclear how the spelling came to be (one suggestion is Hokkien: ).
The product is marketed under the brand name Cap Ibu dan Anak (Malay for "Mother and Son Brand", referring to the brand's logo) in Malaysia,Malaysian Business, Issues 1-6. New Straits Times Press (Malaysia), 1997. p.32 Singapore and Indonesia, also acronymed as OBIDA (as in Obat Batuk Ibu dan Anak) in the lattermost country.
History The formula for pei pa koa was reportedly created by Ip Tin-see, a Qing dynasty physician born in 1680. Ip was asked by county commander Yang Chin to treat his mother's persistent cough. They were so impressed that they created a factory to mass-produce it. In 1946, the Yang family sold the business to Tse Sui-bong, a medicine practitioner, who founded the Nin Jiom Medicine Manufactory. The company was formally incorporated in 1962, and continue to manufacture and sell the product worldwide.Ali F. Farhoomand, (2005). Small Business Management and Entrepreneurship in Hong Kong: A Casebook. Hong Kong University Press. . p.48 The headquarters of the company are located in Hong Kong and Taoyuan, Taiwan.
Availability and marketing of the product expanded in the 1980s, and today it is easily found in North America, most often in Chinese groceries and herbal stores.
Pei pa koa had annual sales of HK$350 million in 2014.
