牛蒡子：
到了秋天成熟，禀受了天地清凉之气，所以味道辛苦、性平、无毒。辛味能疏散结滞，苦味能清泄热邪，药气入入手太阴肺经和足阳明胃经，是疏散风邪、清泄热毒、解毒并利咽喉的圣药。它是治疗痧症全过程的必需药物，也是治疗血热型痘疹的重要药材。但是它的性质寒凉且滑利，气虚导致腹泻的人，千万不要服用。使用时需炒干后研碎，这样就不会耗散药气；如果用于牙痛，则取生牛蒡子研碎后用棉布包裹，含在患处，吐出苦水后即可痊愈。
牛蒡子，主要功效是润肺、疏散气机，治疗牙齿腐蚀疼痛、面目浮肿，退除风热引起的咽痛，以及风湿引起的瘾疹（皮肤红肿瘙痒），还有毒邪形成的疮疡。它辛能散结，苦能泻热，是治疗痘疹、利咽喉、解除阳明经热毒、消除痈肿、疏散风邪、清除内热、清理体内毒素的重要药物。
主治（结合痘疹病症）：润肺金以退除风热，利咽膈以消散各种肿胀，治疗喉痛、解散结气，发痘时能凉血，帮助药力推动痘浆生成，解除阳明经的热毒。凡是痘色红紫、热势旺盛且大便闭结的患者最适合使用。但是它通利肌肤孔窍，多服会内动中焦之气，外致表虚。如病后气血虚弱者，使用它反而会导致真元耗散。如果痘出不畅且伴有腹泻者，尤其忌讳使用。痈疽已经溃破者不要服用。
前胡：
禀受土和金的气，感应秋冬的时令，所以味道苦、辛、平，微寒，无毒。药气入手太阴肺经和手少阳三焦经。苦寒能降泄，辛平能发散，因此是下气除痰、去除结滞、疏散邪气的药物。
前胡，善于消除痰壅，治疗哮喘咳嗽、胸胁痞满、心腹结气，以及伤寒引起的寒热往来、风寒头痛，能去除风痰，清除实热。
主治（结合痘疹病症）：风邪初起发热、疑似未明朗，属于风寒咳嗽且有痰涎的患者可以使用。
按语：前胡，辛味能通畅肺气，解风寒；甘味能愉悦脾气，调理胸腹；苦味能泄厥阴之热；寒性能散太阳之邪。其性属阴主降，与柴胡的上升作用不同，长于下气，气下行则火下降，痰也随之而降。如果不是因外感引起的痰证，以及阴虚火动、气不归元、胸胁逆满的患者，切忌不要加入方剂中使用。
Burdock Fruit (Niubangzi):
It matures in autumn, inheriting the cool and clear qi of heaven and earth; therefore, its flavor is pungent and bitter, nature is neutral, and it is non-toxic. The pungency can disperse stagnation, while bitterness can drain heat; it enters the Hand-Taiyin Lung Meridian and Foot-Yangming Stomach Meridian. It is a supreme herb for dispersing wind, clearing heat, detoxifying, and benefiting the throat. It is essential throughout the course of Sha disease (sand disease) and a key ingredient for blood-heat type smallpox/rash. However, its nature is cold and slippery; those with Qi deficiency leading to diarrhea must strictly avoid taking it. When used, stir-fry until dry and grind into powder so as not to dissipate its qi. For toothache, use raw Burdock Fruit, grind finely, wrap in cotton, hold against the affected area, and spit out the bitter water to be cured.
Burdock Fruit primarily moistens the lungs and disperses Qi, treating corrosive toothache, facial edema, relieving wind-heat sore throat, wind-dampness urticaria, and toxic carbuncles. Its pungency disperses nodules, and bitterness drains heat. It is a crucial herb for benefiting the throat in smallpox/rash, resolving Yangming heat, eliminating swelling, dispersing wind, removing heat, and clearing internal toxins.
Indications (Integrating Smallpox/Rash): Moistens Lung Metal to dispel wind-heat, benefits the pharynx and diaphragm to dissipate various swellings, treats sore throat and dissipates stagnant Qi, cools blood during rash eruption, assists medicine in forming pustules, and resolves Yangming heat toxicity. It is most suitable for cases where the rash is red/purple, heat is severe, and constipation exists. However, it opens muscle pores and promotes bowel movements; excessive use moves the Middle Qi internally and causes exterior deficiency externally. In patients with Qi and Blood deficiency after illness, using it may instead consume true Yuan Qi. If eruption is slow accompanied by diarrhea, it is especially contraindicated. Do not use if carbuncles have already ulcerated.
Peucedani Radix (Qianhu):
Inheriting the Qi of Earth and Metal, and responding to the seasons of Autumn and Winter, its flavors are bitter, pungent, and neutral, slightly cold, and non-toxic. It enters the Hand-Taiyin Lung Meridian and Hand-Shaoyang Sanjiao Meridian. Bitter and cold properties descend, while pungent and neutral properties disperse; thus, it is an herb that directs Qi downward, eliminates phlegm, removes stagnation, and disperses pathogenic factors.
Peucedani Radix excels at eliminating phlegm obstruction, treating asthma, cough, chest and hypochondriac fullness, epigastric and abdominal Qi stagnation, alternating chills and fever from Cold Damage, headache due to wind-cold, removing wind-phlegm, and clearing excess heat.
Indications (Integrating Smallpox/Rash): Can be used when wind-pathogen heat is in early stages, ambiguous, or characterized by wind-cold cough with sputum.
Commentary: Peucedani Radix, with its pungency, unblocks Lung Qi and resolves wind-cold; with its sweetness, it nourishes Spleen Qi and regulates the chest and abdomen; with its bitterness, it drains Jueyin heat; with its cold nature, it disperses Taiyin/Yangming pathogens. Its nature is Yin and descending, differing from Chaihu which ascends. It is particularly effective in directing Qi downward; when Qi descends, Fire descends, and Phlegm follows. For phlegm not caused by external contraction, as well as cases of Yin deficiency with fire hyperactivity, Qi failing to return to its root, and reverse fullness in the chest and hypochondrium, it must strictly be avoided.
