内侍曹都使，新造一宅，迁入半月，饮酒大醉，卧地失音，不能语。召孙至，诊之曰
∶因新宅故得此病耳，半月当愈。但服补心山药丸，治湿用细辛、川芎，月余全安。曹见上
，问谁医。曰∶孙兆郎中。乃召孙问曰∶曹何病也？对曰∶凡新宅壁土皆湿，地亦阴多，人
乍来，阴气未散，心气素虚，醉后毛窍皆开，阴湿之气，入而乘心，故不能语。臣以山药丸
使心气壮盛后，以川芎、细辛去湿，所以能语也。
一人患火病声哑，医皆云不治之症。余诊右部脉洪而有力，自得咽未痛，询前所服，皆
寒凉剂也。遂以天冬、麦冬、沙参、陈皮、贝母、玄参、天花粉、薄荷、桔梗、甘草、细辛
（少许）、海粉、竹茹，数十剂而愈，声如故。间以蜜拌九晒陈槐花，令每睡时细嚼一片，随
津液咽下甚妙。

内侍曹都使，新建了一座宅邸，搬入半个月后，因饮酒大醉，卧于地面导致失声，不能说话。召请孙兆前来诊治，孙兆诊察后说：“这是因为新宅的缘故才会得此病，半个月后会痊愈。只需服用补心山药丸，治疗湿气用细辛、川芎，一个月左右就能完全康复。”曹都使觐见皇上时，皇帝问是谁医治的。回答说：“是孙兆郎中。”于是召见孙兆询问：“曹都使患的是什么病？”孙兆回答说：“凡是新宅的墙壁泥土都潮湿，地面也阴气重，人刚搬来，阴湿之气尚未消散，而患者心气素来虚弱，醉酒之后毛孔张开，阴湿之气侵入并乘虚侵犯心脏，所以不能说话。臣先用山药丸使心气壮盛，再用川芎、细辛祛除湿气，所以能恢复说话。”
有一人患有火病导致声音嘶哑，医生们都认为是无法治愈的病症。我诊察其右部脉象洪大而有力，得知他咽喉并未疼痛，询问之前所服用的药物，都是寒凉药剂。于是使用天冬、麦冬、沙参、陈皮、贝母、玄参、天花粉、薄荷、桔梗、甘草、细辛（少许）、海粉、竹茹，服用数十剂后痊愈，声音恢复如初。平时可用蜂蜜拌合经过九次日晒的陈年槐花，让患者在每次睡觉前细细咀嚼一片，随津液咽下，效果极佳。

Cao Dushi, a palace attendant, had newly built a residence. Half a month after moving in, he became heavily intoxicated by alcohol, lay on the ground, lost his voice, and could not speak. Sun Zhao was summoned for diagnosis. After examining him, Sun said: "This illness is caused by the new residence; it will heal in half a month. Simply take Buxin Shanyao Wan (Heart-Nourishing Yam Pills). To treat dampness, use Xixin (Asari Radix et Rhizoma) and Chuanxiong (Ligustici Chuanxiong Rhizoma); full recovery will occur within a month." When Cao appeared before the Emperor, the Emperor asked who treated him. Cao replied: "Physician Sun Zhao." The Emperor then summoned Sun and asked: "What disease does Cao suffer from?" Sun answered: "The walls of any new residence contain moist soil, and the ground possesses excessive Yin energy. Upon initial entry, the Yin-damp qi has not yet dissipated. If the patient's Heart Qi is inherently deficient, intoxication causes the pores to open, allowing Yin-damp qi to enter and attack the Heart, resulting in aphonia. I first used Shanyao Wan to strengthen the Heart Qi, and then employed Chuanxiong and Xixin to dispel dampness, thereby restoring speech."
A patient suffered from fire-pathology-induced hoarseness. Physicians claimed it was an incurable condition. I palpated the right pulse as flooding and forceful. Learning that his throat did not hurt, and inquiring about previous treatments, I found they had all taken cold-natured formulas. Consequently, I prescribed Tiamendong (Asparagi Radix), Maimendong (Ophiopogonis Radix), Shashen (Glehniae Radix), Chenpi (Citri Reticulatae Pericarpium), Beimu (Fritillariae Bulbus), Xuanshen (Scrophulariae Radix), Tianhuafen (Trichosanthis Radix), Bohe (Menthae Haplocalycis Herba), Jiegeng (Platycodonis Radix), Gancao (Glycyrrhizae Radix et Rhizoma), a small amount of Xixin (Asari Radix et Rhizoma), Haifen (Calamari Endothecium), and Zhuru (Bambusae Caulis in Taeniam). After dozens of doses, he recovered, and his voice returned to normal. Additionally, mixing aged Huaihua (Sophorae Flos) dried nine times with honey, chewing one piece slowly before sleep, and swallowing it with saliva yields excellent results.
