Nin Jiom Pei Pa Koa
King-to Nin Jiom Pei Pa Koa (Chinese: 京都念慈菴川貝枇杷膏; pinyin: 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.
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.." 
Pei Pa Koa is made up of a blend of herbal ingredients including the fritillary bulb (Fritillariae cirrhosae, 川貝母), loquat leaf (Eriobotrya japonica, 枇鈀葉), ladybell root (Adenophora stricta, 南沙參), Indian bread (Wolfiporia extensa, 茯苓), pomelo peel (Citrus maxima, 化橘紅), chinese bellflower root (Platycodon grandiflorum, 桔梗), pinellia rhizome (Pinellia ternata, 半夏), Schisandra seed (Schisandra chinensis, 五味子), Trichosanthes seed (Trichosanthes cucumerina, 瓜蔞子), coltsfoot flower (Tussilago farfara, 款冬花), thinleaf milkwort root (Polygala tenuifolia, 遠志), bitter apricot kernel (Prunus armeniaca, 苦杏仁), fresh ginger (Zingiber officinale, 生薑), licorice root (Glycyrrhiza uralensis, 甘草), and menthol in a syrup and honey base.
It is common to take the preparation right from the bottle served in a tablespoon. It can also be prepared as a drink, by dissolving a tablespoon full in hot water.
