【方歌】发颐肿痛结核般，经属阳明身热寒，伤寒疹毒汗失表，
肿至咽喉调治难。
【注】此证又名汗毒，发于颐颔之间，属足阳明胃经，初起身
发寒热，肿如结核，微热微痛，渐肿如桃如李，疼痛倍
增，由伤寒发汗未尽，或疹形未透，壅积而成。初起宜
荆防败毒散汗之，外以二味拔毒散敷之即消。如消之不
应者，肿痛日增，势必溃脓，宜服托里透脓汤，溃后按
痈疽溃疡门治法。若此证失于调治，或误投寒凉克伐之
药，毒必内陷，肿至咽喉，痰涌气堵，汤水难咽者逆。

【方歌】时毒初发类伤寒，漫肿无头在项间，因感四时不正气，
治分壮弱疏解痊。
【注】此证初起，状类伤寒，憎寒发热，令人恍惚不宁，肢体
酸疼，或兼咽痛，一二日间，发于项腮、颔颐，作肿无
头，渐渐焮赤疼痛，或似结核有根，漫肿色赤，俱由感
冒四时不正邪气，客于经络，酿结而成，非发于病后之
颐毒也。惟在医者，精察疮色，辨别虚实。治法须宜疏
解，不可骤用寒凉，致毒不外发而内攻咽喉者险矣。初
服荆防败毒散汗之，其肿不消者，宜服连翘消毒饮；肿
仍不消，脓势将成，壮者宜服透脓散，弱者宜服托里透
脓汤，外敷二味拔毒散，脓熟针之。溃按痈疽溃疡门治
法。

【方歌】发颐病症表现为腮部肿胀疼痛，肿块形状如同结核，病位归属于阳明经，伴有身体发热和恶寒的症状。若因伤寒疹毒导致汗出而不畅，未能及时解表，致使肿胀蔓延至咽喉部位，则治疗十分困难。
【注】此证又被称为“汗毒”，发生于下颌与面颊之间（颐颔），归属于足阳明胃经。初起时身体出现恶寒发热，肿胀如结核一般，微热且轻微疼痛；随后逐渐肿大如桃或李子大小，疼痛显著加剧。此病多由伤寒发汗不彻底，或麻疹透发不畅，导致邪气壅积而成。初起阶段适宜服用荆防败毒散以发汗解表，外用二味拔毒散敷贴，即可消退。如果用药后肿胀未消，且肿痛日益加重，势必会化脓溃破，此时适宜服用托里透脓汤；溃破后按照痈疽溃疡门的治疗方法处理。如果此证失于调治，或者误用寒凉攻伐的药物，毒邪必然内陷，肿胀蔓延至咽喉，出现痰液涌盛、气道堵塞、汤水难以吞咽的情况，属于逆证（预后不良）。

【方歌】时毒初发时症状类似伤寒，肿胀弥漫无头结，发生在颈部两侧，由于感受了四时不正之气所致，治疗需根据患者体质的强弱进行疏风解表，以求痊愈。
【注】此证初起时，症状类似伤寒，憎寒发热，使人神志恍惚不安，肢体酸痛，有时兼有咽喉疼痛。在一两天内，肿胀发作于颈侧、腮部及下颌，肿胀无头结，逐渐变得红赤疼痛，或者像有根底的结核，肿胀弥漫且颜色红赤。这都是因为感冒了四时不正的邪气，客居于经络之中，酝酿结聚而成，并非病后发生的颐毒。关键在于医生要仔细察看病灶的颜色，辨别虚证实证。治疗方法必须适宜疏风解表，不可骤然使用寒凉药物，否则会导致毒邪不能外发而内攻咽喉，这就危险了。初起时服用荆防败毒散发汗，如果肿胀不消，适宜服用连翘消毒饮；如果肿胀仍不消，脓势即将形成，体质强壮者适宜服用透脓散，体质虚弱者适宜服用托里透脓汤，外用二味拔毒散敷贴，脓成熟后用针穿刺排脓。溃破后按照痈疽溃疡门的治疗方法处理。

[Prescription Verse] Fa Yi (Parotitis) presents with swelling and pain in the parotid region, with lumps resembling tubercles. The disease belongs to the Yangming channel, accompanied by fever and aversion to cold. If caused by Shanghan (Cold Damage) or rash toxins where sweating fails to release the exterior, leading to swelling extending to the throat, treatment becomes difficult.
[Annotation] This condition is also known as "Han Du" (Sweat Poison). It occurs between the jaw and cheek, belonging to the Foot-Yangming Stomach Channel. Initially, it presents with aversion to cold and fever, with swelling resembling a tubercle, slight heat, and mild pain. Gradually, it swells like a peach or plum, with significantly increased pain. It arises from incomplete sweating during Shanghan or failure of the rash to fully erupt, causing stagnation and accumulation. In the early stage, Jingfang Baidu San (Aucklandia and Saposhnikovia Decoction for Overcoming Toxicity) should be taken to induce sweating, and Erwei Baidu San (Two-Ingredient Decoction for Extracting Toxicity) applied externally, which will resolve the swelling. If the swelling does not subside and pain increases daily, suppuration is inevitable; Tuoli Tou Nong Tang (Decoction for Supporting the Interior and Expelling Pus) should be administered. After ulceration, treat according to the methods in the Chapter on Ulcerative Sores. If this condition is neglected or mistreated with cold and purgative drugs, the toxin will sink inward. Swelling extending to the throat, accompanied by surging phlegm, airway obstruction, and difficulty swallowing liquids, indicates a adverse prognosis (Ni syndrome).
Formulas: Jingfang Baidu San (See Chapter on Brain Carbuncle of the Neck); Erwei Baidu San (See Chapter on Early-stage Ulcers); Tuoli Tou Nong Tang (See Chapter on Invading Brain Carbuncle of the Head).
[Prescription Verse] Shi Du (Seasonal Toxins) initially resembles Shanghan, with diffuse swelling lacking a head, occurring in the neck region. It is caused by contracting the abnormal Qi of the four seasons. Treatment involves dispersing and resolving based on the strength or weakness of the patient's constitution to achieve recovery.
[Annotation] At onset, this condition resembles Shanghan, with aversion to cold and fever, causing mental restlessness and limb soreness, sometimes accompanied by sore throat. Within one or two days, swelling appears on the sides of the neck, cheeks, and jaw. The swelling is diffuse without a head, gradually becoming red, hot, and painful, or resembling a rooted tubercle with diffuse redness. This results from contracting abnormal pathogens of the four seasons, which lodge in the meridians and accumulate. It is distinct from post-illness parotitis. The physician must carefully observe the color of the lesion to distinguish deficiency from excess. The treatment method requires dispersing and resolving; sudden use of cold-natured drugs must be avoided, lest the toxin fail to exit outward and attack the throat internally, which would be dangerous. Initially, take Jingfang Baidu San to induce sweating. If swelling persists, Lianqiao Xiaodu Yin (Forsythia Decoction for Eliminating Toxicity) is appropriate. If swelling remains and suppuration is imminent, strong patients should take Tou Nong San (Pus-Expelling Powder), while weak patients should take Tuoli Tou Nong Tang. Apply Erwei Baidu San externally. Once pus matures, puncture with a needle. After ulceration, treat according to the methods in the Chapter on Ulcerative Sores.
