Shidu (Seasonal Toxicity) refers to a condition caused by contracting the abnormal Qi of the four seasons. Its initial presentation resembles Taiyang disease (a syndrome caused by pathogenic factors affecting the Taiyang meridian). It can be fatal between the fifth and seventh days, but if it persists beyond ten days, it may resolve spontaneously even without treatment. Upon pulse diagnosis, slippery (Hua), rapid (Shu), floating (Fu), surging (Hong), deep (Chen), tight (Jin), wiry (Xian), or choppy (Se) pulses are all indicative signs. A floating and rapid pulse indicates that the pathogenic factor is in the exterior; sweating methods should be used. A deep and solid pulse indicates that the pathogenic factor is in the interior; purgative methods should be used. This condition presents as either Yin or Yang syndromes, and may require either diaphoresis or purgation. Commonly, incompetent physicians merely attribute the condition to "heat toxicity" and hastily administer cold-natured drugs, failing to recognize that diseases vary in severity and treatments must follow either counteracting or following principles. How can such matters be neglected? (Cold-natured drugs should not be used lightly.) When there is severe redness, swelling, and pain in the head, face, ears, and neck, accompanied by aversion to cold, thirst, constipation, and a rapid and forceful pulse, this constitutes an excess syndrome in both the exterior and interior. Fangfeng Tongsheng San (Windproof Unblocking Powder) is the primary formula. If there are no exterior or interior symptoms, or if swelling persists despite prior sweating or purgation, Xiaochaihu Tang (Minor Bupleurum Decoction) combined with Jiuhuang Lianqiao (Wine-processed Forsythia Fruit), Xuanshen (Scrophulariae Radix), Bohe (Menthae Haplocalycis Herba), Jiegeng (Platycodonis Radix), Niuzibang (Aubrietiae Semen/Arabis Semen - here referring to Arctii Fructus/Bullactae Fructus contextually often Arctii Fructus/Niupangzi), and Tianhuafen (Trichosanthis Radix) should be used to harmonize. If swelling is severe and painful, and does not subside after sweating or purgation, Bianci (Bian stone therapy) should be used to drain bad blood, and internal detoxifying herbs should be administered. If the pathological process cannot dissipate and suppuration is desired but the pulse is weak and the abscess fails to ulcerate, Tuoli (Supporting the Interior) methods should be employed. In years of famine, infectious outbreaks often occur due to Spleen/Stomach deficiency and irregular diet, allowing pathogens to enter via the deficiency. Treatment should be mild, employing dispersing and detoxifying methods, and Renshen (Ginseng Radix et Rhizoma) must be added to consolidate the Yuan Qi (Original Qi). For cases involving swelling of the jaw and chin (commonly known as Hamawen/Mumps, also called Zhasai), first use Baidu San (Toxin-Detoxifying Powder) to induce slight sweating, followed by frequent, slow administration of Jiuhuang Qinlian (Wine-processed Scutellariae Radix and Coptidis Rhizoma—note: if heat is not extreme and the condition is mild, Zhizi and Huangqin suffice), Xuanshen, Bohe, Lianqiao (Forsythiae Fructus), Gancao (Glycyrrhizae Radix et Rhizoma), Jiegeng, Shengma ( Cimicifugae Rhizoma), and Niuzibang. If the stool is hard and solid, Shudahuang (Prepared Rheum Palmatum Root and Rhizome) should be added. (This method is effective for such conditions regardless of whether they are epidemic.) Generally, if heat does not subside, grain foods should not be given immediately, lest they aid the pathogenic heat. If the pulse is deficient and there is no stagnation, tonification is not prohibited.

During the Taihe era, the populace suffered from epidemics. Initially, patients felt aversion to cold and heaviness of the body, which then progressed to severe swelling of the head and face, inability to open the eyes, upward panting, throat obstruction, dry tongue, and dry mouth. This was commonly called Datou Tianxing (Big Head Epidemic), and various medicines proved ineffective. Li Dongyuan stated that the upper half of the body corresponds to Heavenly Qi; when pathogenic heat lodges between the Heart and Lung, it attacks the head and face causing swelling. Purgatives are required. (Datou Tianxing involves swelling due to Damp-Heat and pain due to Wood/Liver excess. Damp-Heat follows the Yangming channel; Wood excess follows the Shaoyang channel. Pathogens in Yangming cause major head swelling; pathogens in Shaoyang affect the areas before and behind the ears.)

Grind the above into powder. Use half mixed with water, sipping frequently. Use the other half made into honey pills, to be held in the mouth until dissolved. Completion of the course leads to recovery. Alternatively, add Bohe, Chuanxiong, and Danggui, cut into pieces, take five qian per dose, decoct in water, and drink warm frequently. If the stool is hard, add one or two qian of Jiuwei Dahuang (Wine-baked Rheum) to promote bowel movement. For severe swelling, Bianci (stone puncture) is appropriate.
Xiaodu Tuoli San (Detoxification and Interior-Supporting Powder)
Used for Shidu (Seasonal Toxicity) where sweating, purgation, and detoxification have failed to reduce swelling, and the condition is progressing toward suppuration. If pus has not formed, it will dissipate; if formed, it will ulcerate.
