Nin Jiom Pei Pa Koa
King-to Nin Jiom Pei Pa Koa (京都念慈菴川貝枇杷膏, Jīngdū niàn cí ānchuān bèi pípá gāo), commonly known as Nin Jiom Pei Pa Koa or simply Pei Pa Koa, is a Traditional Chinese natural herbal remedy used for the relief of sore throat, coughs, hoarseness, and loss of voice. It is a throat demulcent and expectorant. There's no known side effect in consuming this product due to the natural ingredients, and is suitable for all ages; however, the dosage needs to be reduced if the patient is a child under the age of 12, and to consult physician if the patient is pregnant.
In the name of the company, "King-to" means "capital", referring to Peking, and "Nin Jiom" means "in memory of my mother"; hence, it stresses the important virtue of filial piety. "Pei Pa Koa" means "Loquat syrup".
The formula for Pei Pa Koa was originally created by Doctor Ip Tin-See, a physician for the Qing Dynasty. Yang Jin, a county 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, it is manufactured and sold by Nin Jiom Medicine Manufactory Limited, a Hong Kong corporation. It is available worldwide.
Pei Pa Koa has annual sales of 45 million USD.
A study at the China Academy of Traditional Chinese Medicine published in a 1994 article, "Pharmacological studies of nin jion pei pa koa", states that Nin Jiom Pei Pa Kao "had significant cough relieving and sputum removing effects. It also had an evident effect on relieving asthma in vivo and in vitro. In four acute or sub-acute inflammatory models, the anti-inflammatory effect was marked.."
