Pediatric cold cough arises from underlying lung deficiency and a preference for consuming raw or cold foods, leading to cold pathogenic factors injuring the Lung, resulting in cough. The manifestations include a pale complexion, copious clear and thin sputum, and clear green nasal discharge. In the initial stage, ancient methods primarily prescribe Shenghui Jupi Yin (Saintly Benefit Tangerine Peel Decoction), which contains Renshen (Ginseng Radix et Rhizoma), Beimu (Fritillariae Bulbus), Ziyexia (Perillae Folium), Chenpi (Citri Reticulatae Pericarpium), Jiegeng (Platycodonis Radix), Xingren (Armeniacae Semen Amarum), with Hongzao (Jujubae Fructus) used as an adjuvant. If the condition persists for a long time without resolution, ancient methods primarily prescribe Bufu Ejiao San (Lung-Nourishing Donkey-Hide Gelatin Powder), containing Renshen (Ginseng Radix et Rhizoma), Fuchao Ejiao (Donkey-Hide Gelatin stir-fried with bran), Chao Niuzilong (Buddlejae Seminis stir-fried), Chao Xingren (Armeniacae Semen Amarum stir-fried), Nuomi (Oryzae Sativum Glutinosa Semen), Zhigancao (Glycyrrhizae Radix et Rhizoma preparata), Madouling (Aristolochiae Fructus), etc., decocted in water and taken after meals.
[Chen Shouzhen’s Note] Pediatric cold cough, in addition to the aforementioned symptoms, is also characterized by qi stagnation and panting, turbid voice, absence of sweating, nasal congestion, and a heavy nasal quality of voice.
