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

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

发颐表现为腮部肿胀疼痛，肿块如结核般坚硬，病证归属于阳明经，伴有身体发热和恶寒。若因伤寒疹毒未能通过发汗解表而透发，导致肿胀蔓延至咽喉，则调治困难。
【注】此证又名“汗毒”，发生于颐颔（下巴与脸颊）之间，归属于足阳明胃经。初起时身体出现恶寒发热，肿块像结核一样，微热微痛；随后逐渐肿大如桃李，疼痛加倍。此病由伤寒发汗不彻底，或疹形未完全透出，邪气壅积而成。初起宜用荆防败毒散发汗治疗，外用二味拔毒散敷贴即可消散。如果消肿无效，肿痛日益加重，势必化脓溃破，宜服用托里透脓汤；溃破后按照痈疽溃疡门的治法处理。如果此证失于调治，或误投寒凉克伐的药物，毒邪必然内陷，肿胀波及咽喉，痰涌气堵，连汤水都难以下咽，属于逆证（预后不良）。

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。因感受四时不正之气所致，治疗需根据患者体质的强弱进行疏解以痊愈。
【注】此证初起，症状类似伤寒，憎寒发热，令人神志恍惚不安，肢体酸痛，有时兼有咽痛。一两天内，发作于颈腮、下巴颐颌部位，肿胀无头结，渐渐发红疼痛，有的像有根的结核，有的漫肿色赤。这都是由于感冒四时不正邪气，客居于经络，酝酿结聚而成，并非病后发生的颐毒。关键在于医生要精细观察疮色，辨别虚实。治疗方法应当疏风解表，不可骤然使用寒凉药物，以免毒邪不能外发反而内攻咽喉，那样就很危险了。初服荆防败毒散发汗，如果肿胀不消，宜服用连翘消毒饮；肿胀仍不消，脓势即将形成，体质壮实者宜服用透脓散，体质虚弱者宜服用托里透脓汤，外用二味拔毒散敷贴，脓熟后用针穿刺排脓。溃破后按照痈疽溃疡门的治法处理。

Fa Yi (Parotitis) presents with swelling and pain in the parotid region, with masses hard like tubercles. The syndrome belongs to the Yangming channel, accompanied by fever and aversion to cold. If due to Shanghan (Cold Damage) or rash toxins failing to be released through sweating, leading to swelling extending to the throat, treatment becomes difficult.
[Note] This syndrome is also known as "Han Du" (Sweat Poison). It occurs between the mandible and cheek, belonging to the Foot-Yangming Stomach Channel. Initially, there is aversion to cold and fever, with a mass resembling a tubercle, slightly hot and painful. Gradually, it swells like a peach or plum, with doubled pain. This condition arises from incomplete sweating in Shanghan, or failure of the rash to fully emerge, causing stagnation and accumulation. At the onset, Jingfang Baidu San (Astragalus and Saposhnikovia Decoction for Overcoming Toxins) should be used to induce sweating, and Erwei Baidu San (Two-Ingredient Decoction for Extracting Toxins) applied externally to dissipate the swelling. If dissipation fails and swelling and pain increase daily, suppuration will inevitably occur; Tuoli Tou Nong Tang (Decoction for Supporting the Interior and Penetrating Pus) should be taken. After ulceration, treat according to the methods for Ulcerated Carbuncles and Sores. If this syndrome is neglected or mistreated with cold-cooling and draining medicines, the toxin will sink inward. Swelling extends to the throat, with surging phlegm and blocked qi, making it difficult to swallow liquids; this is a Ni syndrome (adverse prognosis).

Shi Du (Seasonal Epidemic Toxin) initially resembles Shanghan, presenting with diffuse swelling without a head in the neck region. It is caused by contracting the abnormal Qi of the four seasons. Treatment requires differentiation based on the strength or weakness of the constitution, using dispersing and resolving methods for recovery.
[Note] At the onset, this syndrome resembles Shanghan, with aversion to cold and fever, causing mental restlessness and limb soreness, sometimes accompanied by sore throat. Within one or two days, it appears on the neck, cheeks, and jaw, swelling diffusely without a head, gradually becoming red and painful. Some resemble rooted tubercles, while others are diffusely swollen and red. All result from contracting abnormal seasonal pathogens lodging in the collaterals and meridians, brewing and knotting together; it is not the Ji Du (Jaw Poison) occurring after an illness. The key lies in the physician's precise observation of the lesion's color to distinguish deficiency and excess. The treatment method must focus on dispersing and resolving; sudden use of cold-cooling herbs must be avoided to prevent the toxin from failing to exit outward and instead attacking the throat internally, which would be dangerous. Initially, take Jingfang Baidu San to induce sweating. If the swelling does not subside, take Lianqiao Xiaodu Yin (Forsythia Decoction for Disinfecting Toxins); if swelling persists and suppuration is imminent, those with strong constitutions should take Tou Nong San (Pus-Penetrating Powder), while those with weak constitutions should take Tuoli Tou Nong Tang. Apply Erwei Baidu San externally. Once the pus is ripe, puncture with a needle. After ulceration, treat according to the methods for Ulcerated Carbuncles and Sores.
