详观一百十一号（绍兴医药学星期报）所登之案，其呃逆终不愈者，以其虚而兼郁也。然观其饱时加重，
饥时见轻，知病因之由于郁者多，由于虚者少。若能令其分毫不郁，其呃当止。郁开呃止，气化流通，虽
有所虚，自能渐渐撤消。特是理虚中之郁最为难事，必所用之药分毫不伤气化，俾其郁开得一分，其气
化自能撤消一分，始克有效。拙拟医方篇中载有卫生防疫宝丹，原系治霍乱急证之方，无论其证因凉因热，
皆屡试屡验。后有沈阳赵××，得温病甚剧，舁至院中求为延医，数日就愈，忽作呃逆，昼夜不止，
服药无效。因思卫生防疫宝丹，最善行气理郁，俾一次服五十粒，呃逆顿止。又数日有陈姓患呃逆证，旬日
不止，眠食俱废，精神疲惫，几不能支。亦治以卫生防疫宝丹，俾服八十粒，亦一次即愈。由斯知卫生防疫
宝丹，治呃逆确有把握，无论其为虚、为郁，用之皆可奏效也。盖方中冰片、薄荷冰为透窍通气之妙
药，而细辛善降逆气，白芷善达郁气，朱砂能镇冲气之冲逆，甘草能缓肝气之忿激，药非为呃逆专方，而无
一味非治呃逆必需之品，是以投之皆效也。若其人下元虚甚者，可浓煎生山药汁送服。其挟热者，白芍、麦冬
煎汤送服。其挟寒者，干姜、浓朴煎汤送服。愚用之数十次，未有不随手奏效者。若仓猝不暇作丸
药，可为末服之。
仔细查看绍兴医药学星期报刊登的第111号医案，该患者的呃逆（膈肌痉挛）始终未能痊愈，是因为其病机属于虚证兼有气郁。然而观察患者饱食时症状加重，饥饿时症状减轻，可知病因多由气郁引起，少由虚损引起。如果能使其气机分毫不郁滞，呃逆自然停止。气郁解除而呃逆停止，气化功能流通恢复，即使身体有所虚损，也能逐渐消除。只是调理虚证中的气郁是最为困难的事，必须所用药物丝毫不损伤气化功能，使得气郁每解开一分，气化功能便自行恢复一分，这样才能见效。我在拙作《医学衷中参西录·医方篇》中记载的卫生防疫宝丹，原本是治疗霍乱急证的方剂，无论病情是因寒凉还是因热邪所致，都屡试屡验。后来沈阳有一位赵姓患者，患温病（感受温热邪气引起的急性外感热病）非常严重，被抬到诊所求我延请医生诊治，几天后病情好转，突然发生呃逆，昼夜不停，服用其他药物无效。于是我想到了卫生防疫宝丹，它最擅长行气理郁，让患者一次服用五十粒，呃逆立刻停止。又过了几天，有一位陈姓患者患呃逆证，十多天不止，睡眠和饮食都废弛，精神疲惫，几乎无法支撑。也用卫生防疫宝丹治疗，让他一次服用八十粒，也一次就痊愈了。由此可知，卫生防疫宝丹治疗呃逆确有把握，无论呃逆是由于虚证还是由于气郁，使用它都能奏效。因为方中的冰片、薄荷脑是透达孔窍、通畅气机的妙药，而细辛善于降逆气，白芷善于通达郁结之气，朱砂能镇摄冲脉之气的上逆，甘草能缓和肝气的忿激，此药并非专为呃逆设立的方剂，但没有一味药不是治疗呃逆所必需的，所以投用都有效。如果其人下元（肾与命门）虚损严重的，可用浓煎的生山药汁送服。如果兼挟热邪的，用白芍、麦冬煎汤送服。如果兼挟寒邪的，用干姜、厚朴煎汤送服。我使用此法数十次，没有不随手奏效的。如果仓促之间来不及制作丸药，可以将其研为粉末服用。
A careful examination of Case No. 111 published in the *Shaoxing Medical and Pharmaceutical Weekly Report* reveals that the patient's hiccups (spasmodic contraction of the diaphragm) remained incurable because the pathology involved both deficiency and Qi stagnation. However, observing that symptoms worsen after fullness and alleviate during hunger indicates that the etiology is predominantly due to Qi stagnation rather than deficiency. If one can ensure that there is not even a trace of Qi stagnation, the hiccups will cease. Once the stagnation is resolved and hiccups stop, the physiological transformation and circulation of Qi (Qi Hua) will flow freely; even if there is some underlying deficiency, it will gradually dissipate on its own. The most difficult aspect lies in regulating Qi stagnation within a context of deficiency. It is essential that the prescribed herbs do not impair the physiological transformation of Qi in the slightest. Only when every fraction of stagnation is resolved can the physiological transformation of Qi recover by a corresponding fraction, thereby achieving efficacy. In my work *Yixue Zhongzhong Canxi Lu*, Chapter on Medical Formulas, I recorded the *Weisheng Fangyi Baodan* (Health Protection and Epidemic Prevention Precious Pill), originally formulated for treating acute cholera. Regardless of whether the condition was caused by cold or heat, it has proven effective upon repeated trials. Later, a Mr. Zhao from Shenyang suffered from severe Warm Disease (acute febrile disease caused by warm pathogenic factors). He was carried to the clinic seeking medical attention. After several days of treatment, his condition improved, but he suddenly developed persistent hiccups day and night, which did not respond to other medications. Recalling that *Weisheng Fangyi Baodan* excels at promoting Qi movement and resolving stagnation, I administered fifty pills at once, and the hiccups ceased immediately. A few days later, a Mr. Chen presented with hiccups lasting over ten days, resulting in loss of sleep and appetite, extreme mental fatigue, and near exhaustion. He was also treated with *Weisheng Fangyi Baodan*, taking eighty pills at once, and recovered completely in a single dose. This demonstrates that *Weisheng Fangyi Baodan* is reliable for treating hiccups, effective regardless of whether the cause is deficiency or stagnation. This is because Borneol (Bingpian) and Menthol (Bohebing) in the formula are excellent agents for penetrating orifices and unblocking Qi, while Asarum (Xixin) effectively descends rebellious Qi, Angelica dahurica (Baizhi) effectively disseminates stagnant Qi, Cinnabar (Zhusha) calms the upward rebellion of Chong Qi (Rebellious Qi of the Penetrating Vessel), and Licorice Root (Gancao) moderates the irritability of Liver Qi. Although this is not a formula specifically dedicated to hiccups, every ingredient is essential for treating hiccups; hence, it yields consistent results. For patients with severe deficiency of the Lower Yuan (Kidney and Mingmen), the pills should be taken with a concentrated decoction of Dioscorea opposita rhizome (Shanyao). For those with accompanying Heat, they should be taken with a decoction of White Peony Root (Baishao) and Ophiopogon tuber (Maidong). For those with accompanying Cold, they should be taken with a decoction of Dried Ginger (Ganjiang) and Magnolia bark (Houpo). I have used this method dozens of times without fail. If pills cannot be prepared in an emergency, the powder form may be administered directly.
