笔者早年随师姚景南先生(肇庆市名老中医),见师常于难治性咳嗽病例中加入白及10～20g,其效极佳,甚觉惊奇。诊余查阅本草方书均无所获,请教于师,师言:“白及味苦甘而性凉,颜色白而入肺,前人均谓其能收敛止血,消肿生肌,其实白及又善止咳,尤对阴虚咳嗽、肺热咳嗽、百日咳、痨咳有良效,惟其味涩,故有表证者慎用。”笔者恍然大悟,知此为吾师独有心得。遂于日后诊务中,随证加入白及,共治疗103例,屡用屡验,若将白及研末冲服其效更佳。 In the early years, the author followed the teacher Mr. Yao Jingnan (Zhaoqing City, old and famous Chinese medicine practitioners). He often added white and 10 to 20 g to the case of refractory cough. The effect was excellent and he was surprised. After consulting the medical books in the medical consultations, they all learned nothing. Ask the teacher, the teacher said: "Bitter and cool, white and lung, the former per capita said that it can converge to stop bleeding, swelling and myogenic, in fact, white and good Relieving cough, especially for yin deficiency cough, hyperactivity cough, whooping cough, and expectorant cough have good effect, but its taste is astringent, so there are watchers who are cautious about using it.” The author suddenly realized that this is a unique experience for my teacher. In the future, in the future, 103 patients were treated with the card. A total of 103 patients were repeatedly tested. If white and powdered, it would be more effective.
