按∶蜀椒辛宜肺部，热宜脾家，故并入之。证属寒凝，诚为要剂。然过于行散，多服令
人乏气，且发热疾，闭口者能杀人，不可不慎。
雷公云∶一名南椒，凡使须去目及闭口者不用。其椒子先须酒拌，令湿蒸，从巳至午放

枫香：味道辛、苦，性质平和，无毒，归脾经和肝经。主要作用是驱除恶气，治疗疮疡毒邪，缓解牙齿疼痛，消除风气，治愈痢疾。对霍乱退热、消退瘾疹（荨麻疹）效果最为迅速。又名白胶，又名芸香。
按语：枫香的辛味适宜入肺经以宣散，苦味适宜入脾经以燥湿，若治节功能得当，仓廪（脾胃运化）功能正常，那么恶气等病症，还担心不能痊愈吗？
蜀椒：味道辛，性质大热，有毒，归肺经和脾经。主要作用是治疗冷气引起的咳嗽气逆，心腹部的邪气，风寒湿痹痛，症瘕积聚（腹内结块）、霍乱转筋（肌肉痉挛），停留的饮邪和宿食，开通腠理，疏通血脉，坚固牙齿头发，调和关节，能够辟除瘟疫，可以清洗漆疮。微炒后能发汗。使用时需去除黄色的谷壳。
按语：蜀椒的辛味适宜入肺经，热性适宜入脾家，所以将其归入这两经。病症属于寒凝阻滞时，它确实是重要的药剂。然而它过于行气发散，多服会让人气虚乏力，而且如果患者发热且口闭不开，服用它能致人死亡，不可不谨慎。
雷公说：蜀椒又名南椒，凡是炮制都需要去掉椒目及闭口的花椒不用。其椒子先用酒拌湿，蒸制，从巳时到午时放凉。又有另一种制法：微炒至出汗，投入容器中捣碎，取红皮，去除黄谷，密封收存备用。
生姜：味道辛，性质温和，无毒，归肺、心、脾、胃四经。主要作用是通利神明，去除秽恶之气，疏散风寒，止住呕吐，消除泄泻，散开郁结，通畅脾胃，治疗痰嗽，制约半夏毒性。配伍药物时，若要发挥热性则去皮，若要保留冷性则留皮，与黄芩相畏。
按语：生姜的辛味入肺经，肺得到所胜之气（金克木，此处指肺气宣降得宜），则气机通畅宣畅，主宰精神意识，所以能通利神明。神明通则一身之气都为我所用，从而占据优势。一身之气占优势，则中焦的元气安定，脾胃受纳和排泄的功能正常，邪气就无法容身，所以能去除秽恶之气。经典说：“秋天不吃姜”，是因为秋季燥金主令，天道收敛收藏。姜味道辛，善于发散肺气。人效法天地而生，没有违背天地和谐而还能受益的。谚语说“晚上不吃姜”，也是因为夜间气机收敛而姜性发散。如果是为了治病，就不必拘泥于此，应当常用但不宜多用。
Fengxiang (Liquidambar): Flavor is pungent and bitter, nature is neutral, non-toxic. Enters the Spleen and Liver meridians. Primarily expels evil qi, treats ulcer toxins, stops toothache, dissipates wind-qi, and cures dysentery. Most effective in stopping cholera-like symptoms and retreating urticaria (wind rash). Also known as Baijiao, also known as Yunxiang.
Commentary: The pungency of Fengxiang is suitable for dispersing into the Lung; the bitterness is suitable for drying the Spleen. If the regulation (Zhi Jie) is appropriate and the granary (Spleen/Stomach transport) functions correctly, why worry that evil qi and other syndromes will not heal?
Shujiao (Sichuan Pepper): Flavor is pungent, nature is hot and toxic. Enters the Lung and Spleen meridians. Primarily treats cold qi causing cough and rebellious qi, evil qi in the heart and abdomen, bi-syndrome due to wind-cold-dampness, zheng-jia and ji-ju (abdominal masses), cholera with muscle cramps, retained fluid and old food. Opens the cou-li (pores/skin texture), unblocks blood vessels, strengthens teeth and hair, harmonizes joints, can ward off epidemics, and can be used to wash away lac poisoning. Lightly stir-fried to induce sweating. Use after removing yellow chaff.
Commentary: The pungency of Shujiao is suitable for the Lung, and its heat is suitable for the Spleen, hence it enters these two meridians. When the syndrome belongs to cold coagulation, it is indeed a crucial agent. However, it is too dispersing; excessive use causes qi deficiency. Moreover, if the patient has fever and closed mouth, it can be fatal; caution is essential.
Lei Gong said: It is also called Nanjiao. In processing, one must remove the seed eyes (mu) and those with closed shells. The pepper seeds should first be mixed with wine until moist, steamed, and cooled from Si hour to Wu hour. Another method involves lightly stir-frying until "sweating," pounding in a vessel, taking the red skin, removing the yellow chaff, and storing tightly for use.
Shengjiang (Fresh Ginger): Flavor is pungent, nature is warm, non-toxic. Enters the Lung, Heart, Spleen, and Stomach meridians. Primarily promotes clarity of the spirit, removes foul odors, disperses wind-cold, stops vomiting, eliminates diarrhea, dissipates stagnation, unblocks the Spleen and Stomach, treats phlegm-cough, and moderates the toxicity of Banxia (Pinellia Rhizome). When combining herbs, peel it if heat is desired, keep the peel if coolness is desired; it is incompatible with Huangqin (Scutellaria Root).
Commentary: The pungency of Shengjiang enters the Lung. When the Lung receives its controlling influence, qi flows freely and smoothly, governing the spirit. Thus, it promotes clarity of the spirit. When the spirit is clear, the qi of the whole body serves the individual, gaining dominance. When the qi of the whole body dominates, the primordial qi of the Middle Jiao stabilizes, and the Spleen and Stomach's functions of reception and excretion proceed normally, leaving no room for evil qi; thus, it removes foul odors. The classics state: "Do not eat ginger in autumn," because dry metal governs the season, and the heavenly way gathers and stores. Ginger is pungent and good at dispersing Lung qi. Humans are modeled on heaven and earth; none who violate the harmony of heaven and earth still receive benefit. The proverb says, "Do not eat ginger at night," because night qi gathers while ginger's nature disperses. However, when treating disease, one should not be dogmatic; it should be used commonly but not excessively.
