Most expectorants also have the effects of relieving cough asthma; antitussives and antiasthmatics , on the other hand the effect of resolving sputum. So they are generally referred to as drugs for resolving sputum and relieving cough and asthma

凡具祛痰或消痰作用的药物，称为化痰药；能 减轻或制止咳嗽和喘息的药物，叫止咳平喘药。 一般咳喘每多挟痰，痰多亦必致咳喘，而化痰 药多兼止咳、平喘之功，止咳平喘药亦多兼化 痰之效。 两类药合于一章，总称之为化痰止咳平喘药

Effects Resolving phlegm; relieving cough and asthma 功 效：化痰、止咳、平喘。 Indications Expectorants are used for treating phlegm syndrome; Antitussives and antiasthmatics are chiefly indicated for cough and asthma due to affection by exo-pathogenic factors and impairment of the functions of internal organs. 适应证：痰多之咳喘以及癫痫惊厥、瘿瘤瘰疬、阴疽流注等证

Compatibility In treatment, antitussives and antiasthmatics are often used in combination with Expectorants, and vice versa. Diseases that comes or stems from internal damage or exogenous invasion may lead to profuse sputum and cough

Therefore, it is necessary in treatment to not only use proper antitussives, antiasthmatics and expectorants according to the disease condition, but also to use necessary combination of drugs according to various etiological factors, and with due to consideration of the exterior and interior, deficiency and excess, and heat and cold of the disease, if satisfactory therapeutic effect is to be obtained

第一节 化痰药 Expectorant Effects and Indications Drugs for resolving cold-phlegm are warm and dry, and have the functions of warming the lung to eliminate phlegm. Drugs for resolving heat-phlegm are cold or cool, and have the functions of resolving heat￾phlegm. Some of the drugs are sleek and have the function of moistening dryness. Some of the drugs are salty and have the function of softening hardness to dissipate stagnation

Drugs for resolving heat-phlegm are used for treating cough, asthma, yellow thick sputum, and epilepsy, apoplexy, convulsion, goiter, scrofula. Drugs for resolving cold-phlegm are used for treating cold-phlegm syndrome and damp￾phlegm syndrome, such as cough, asthma, profuse white phlegm, greasy coating, vertigo, numbness of the limb, deep rooted carbuncle of Yin nature and metastasis abscesses
