（见白喉忌表抉微）
白喉禁忌。诸家言之甚详。兹条列于下。其尤须发明斟酌者。略参如左。
白喉为手太阴燥气化火。治宜滋阴清热。即挟有少阳少阴木火标症。亦宜仿吴氏温
热法。清中夹疏。慎不可用升柴粉葛等温升之味。以助其焰。此理吴氏辨之甚详。
可熟玩也。张善吾除瘟化毒神功辟邪诸散。皆首用葛根。恰犯所忌。吐法为六淫要
诀。唯此症大忌。恐一经涌吐。其势即上窜也。
麻桂羌防为寒湿家发汗之祖药。治温热者已严加禁忌。况白喉纯系燥火。岂可复投
发汗。致伤津液。
喉症如火毒蕴结于肠胃之间。腹痛便闭者。均可用下法。唯白喉切宜谨慎用之。
盖燥火烁金。肺汁内涸。治当以养阴清燥为主。井非一二剂所能了事。若大下之
后。胃气告匮。阴药安能任受。不独重伤津液也。其必不得已者。可仿吴氏宣白承
气法。不可直用仲景之三承气也。
喉科用刀针者。多由风火郁结于血分。红肿痛闭。危在顷刻。必须刺取恶血。以泄
其气。使火气自衰。今白喉来势既缓。自可按法施治。何必漫用刀针。致伤阴血。
唯太阴本症较轻。少阳少阴风火标症较重。红肿异常。甚则紫。项背俱肿者。可间
用刺法。其发白处。仍不可犯。此理于上三经同病条略加阐发。可参玩也。
将上述药物研磨成细粉。用米醋煎煮成浓汁。以药汁调和药粉制成如绿豆大小的丸剂。每次服用四分（约1.2克）。用茶汤浸泡至软化后，捣烂送服。儿童用量减半。
（出自《白喉忌表抉微》）
白喉的禁忌症，各家论述非常详尽。现逐条列举如下。其中特别需要阐明和斟酌的内容，略作补充如下：
白喉是由于手太阴肺经的燥气化火所致，治疗应当滋阴清热。即使兼有少阳、少阴经的木火标证，也应当仿照吴鞠通氏温病学派的方法，在清热的同时兼顾疏解。千万不可使用升麻、柴胡、粉葛等具有温升作用的药物，以免助长火势。这一道理吴鞠通氏辨析得非常详细，可以仔细研读体会。张善吾所著的除瘟化毒神功辟邪诸散，都首先使用葛根，恰好犯了上述禁忌。吐法是治疗六淫外感的重要方法，唯独此症大忌。恐怕一旦引发涌吐，病势就会向上窜动加剧。
麻黄、桂枝、羌活、防风是治疗寒湿病症发汗的祖方药物，治疗温热病时已经严格禁止使用，何况白喉纯属燥火之证，岂可再投以发汗药，导致损伤津液？
咽喉病症如果因火毒蕴结于肠胃之间，出现腹痛、大便闭塞的症状，都可以使用下法（泻下通便）。唯独白喉切需谨慎使用。因为燥火灼伤肺金，导致肺中津液内竭，治疗应当以养阴清燥为主，并不是一两剂药就能解决的事情。如果在峻下之后，胃气衰竭，阴柔的药物又怎能承受得住？这不仅会重伤津液。如果实在不得已而为之，可以仿照吴鞠通氏的宣白承气汤法，不可直接直接使用张仲景的三承气汤。
喉科使用刀针放血的情况，多是因为风火郁结在血分，导致红肿疼痛闭塞，情况危急，必须刺破放出恶血，以泄其气，使火气自然衰退。如今白喉发病势头较缓，自然可以按照常规法治愈，何必随意使用刀针，以致损伤阴血？只有当太阴本证较轻，而少阳、少阴的风火标证较重，红肿异常，甚至呈现紫色，颈部和背部都肿胀的情况下，才可以间歇性地使用刺法。对于发白的部位，仍然不可触犯。这个道理在上文关于这三经同病的条目中已有略加阐发，可以参考研读。
Transparent Realgar (ground finely and purified by water flotation) Curcumae Longae Rhizoma (Yujin, 郁金) Semen Crotonis Tiglii Frost (Badou Shuang, 巴豆霜)
The above herbs are ground into fine powder. Rice vinegar is boiled to make a concentrated decoction. The powder is mixed with the vinegar juice to form pills the size of mung beans. Each dose is four fen (approx. 1.2g). Soak in tea soup until soft, then mash and swallow. Children's dosage is halved.
(From *Baihou Jibiao Juwei*)
Contraindications for Baihou (Diphtheria-like throat disease) have been discussed in detail by various authors. They are listed item by item below. For those points requiring particular elucidation and deliberation, brief comments are added as follows:
Baihou arises from the transformation of dryness-heat fire in the Hand-Taiyin Lung Meridian. Treatment should focus on nourishing yin and clearing heat. Even if accompanied by superficial symptoms of wood-fire from the Shaoyang and Shaoyin meridians, one should follow Wu Juzhong’s method in Warm Disease theory: clearing heat while simultaneously dispersing. One must strictly avoid using warming and ascending herbs such as Shengma (Cimicifugae Rhizoma), Chaihu (Bupleuri Radix), or Fenge (Puerariae Radix), as these would assist the flame. This principle was analyzed in great detail by Wu Juzhong; it can be studied carefully. Zhang Shanwu’s formulas, such as Chuwen Huadu Shengong Pixie San, all prioritize the use of Gegen (Puerariae Radix), which precisely violates this contraindication. Vomiting therapy is a key technique for treating the Six Exogenous Pathogens, but it is strictly contraindicated in this condition. There is a fear that inducing vomiting will cause the pathogenic qi to surge upward.
Mahuang (Ephedrae Herba), Guizhi (Cinnamomi Ramulus), Qianghuo (Notopterygii Rhizoma et Radix), and Fangfeng (Saposhnikoviae Radix) are ancestral herbs for inducing sweating in cold-damp conditions. Their use is strictly prohibited in warm diseases; how much more so in Baihou, which is purely dryness-fire? Administering diaphoretic agents would damage body fluids.
In throat disorders, if fire-toxin accumulates between the intestines and stomach, causing abdominal pain and constipation, purgative methods may be used. However, in Baihou, purgatives must be used with extreme caution. Dryness-fire scorches metal (Lung), leading to the internal depletion of Lung fluids. Treatment must primarily focus on nourishing yin and clearing dryness; it cannot be resolved in just one or two doses. After severe purgation, Stomach qi becomes exhausted, making it impossible for yin-nourishing medicines to be tolerated. This not only severely damages body fluids. If absolutely necessary, one may imitate Wu Juzhong’s Xuanbai Chengqi Tang method, rather than directly applying Zhang Zhongjing’s three Chengqi Decoctions.
The use of knives and needles in throat surgery is usually due to wind-fire stagnating in the blood level, causing redness, swelling, pain, and obstruction, with danger imminent. It is necessary to puncture and release evil blood to vent the qi, allowing the fire to subside naturally. Since Baihou has a slower onset, it can be treated according to standard methods. Why resort to indiscriminate use of knives and needles, thereby injuring yin blood? Only when the Taiyin primary syndrome is mild, but the Shaoyang and Shaoyin wind-fire secondary syndromes are severe, with abnormal redness and swelling, turning purple, and swelling extending to the neck and back, may puncturing be used intermittently. Areas showing white patches must still not be touched. This principle is elaborated slightly in the section on simultaneous involvement of these three meridians; please refer to it.
