（本经中品）
界域相连，依真傍假呼卢，应六性相近也。
【气味】辛温，无毒。
【主治】主寒热鼠 瘰 ，生疮，破结聚气，下瘀血，除湿疸。
【核】曰∶假苏，即荆芥。窃似卢苏，原属野生，今为俗用，遂多种莳。二月布子生苗，
方茎细叶，似落篱而细；八月开小花，作穗成房，房如水苏，内有细子似葶苈，色黄赤，连
穗
【 】曰∶假者苏之，故名假苏。如假寒热为鼠 ，为瘰 ；假气为结，为聚；假血为
瘀；假湿为疸；假伪非真者，苏苏震行，缓散自释矣。别名疆 、荆芥。疆画界分，荆方芥
辛也。言能画疆界，殊方域，悉新以辛也。
（本经中品）
纤细虚中，宛如毛孔。故可对待满实之毛孔。
【气味】苦温，无毒。
【主治】主中风，伤寒，头痛，温疟，发表汗出，去邪热气，止咳逆上气，除寒热，破
症
【核】曰∶出荥阳、中牟、汴京者为胜。所在之处，冬不积雪。二月生苗，纤细劲直，
外黄内赤，中虚作节如竹；四月梢头开黄色花，结实如百合瓣而紧小，又似皂荚子而味甜；
根色紫赤，有雌雄两种，雌者开花结实。修治，去根及节，煮十多沸，掠去白沫，恐令人烦
根节能止汗故也。浓朴、白薇为之使。恶辛夷、石苇。
【 】曰∶表黄里赤，中虚象离，生不受雪，合辅心王，宣扬火令者也。主治寒风温疟，
标见头痛之标经，侵淫部署之首，形层之皮，致毛孔满实，逆开反阖者，宣火政令，扬液为
汗而张大之，八万四千毛孔，莫不从令，而去邪热气矣。但热非病反其本，中标之病，即寒
风炎威之气，使人毛孔毕直，皮肤闭而为热，劲切之性，仍未反乎本气之寒也。咳逆上气者，
毛孔满闭，则不能布气从开，故上逆而咳。症坚积聚者，假气成形，则不能转阖从开，故积
坚而症。盖不独本性不迁，即本气犹未变易，故仍可转入为出，易冬为春，否则妄汗亡液，
败乱心王矣。

[Jiasu (Perilla Leaf / Schizonepeta)]
Boundaries of regions are connected; relying on the "True" and attaching to the "False," it is called "Lu" (homophone for Su), because its nature is similar to one of the Six Natures.
[Flavor and Toxicity] Pungent, Warm, Non-toxic.
[Indications] Primarily treats alternating chills and fever, scrofula (lymph node tuberculosis), sores and ulcers, breaks up Qi stagnation and accumulation, descends blood stasis, and removes damp jaundice.
[Analysis] It is said: Jiasu is Jingjie (Schizonepeta). It borrows the name of Lusue (referring to a certain wild herb); originally belonging to wild plants, now widely used by common people, thus it is mostly cultivated. In February, seeds are sown and seedlings emerge; the stem is square, leaves are fine, resembling grass on a fence; in August, small flowers bloom, forming spikes with capsules like Shuisu (Water Mint), containing fine seeds resembling Tinglizi (Lepidium Seed), yellowish-red, attached to the spike.
[Commentary] It is said: "Jia" means to restore/resuscitate, hence named Jiasu. Just as "Jia" is used to treat scrofula and lymphadenopathy caused by chills and fever; to resolve Qi knotting and gathering; to dissipate blood stasis; to clear dampness-induced jaundice. What is "false" or "fake" is not true; the herb vibrates and moves, slowly dispersing, thereby naturally releasing the pathogen. Alternative names include Jiang and Jingjie. "Jiang" refers to drawing boundaries; "Jing" refers to being square/upright; "Jie" refers to pungency. This implies it can delineate boundaries, distinguish regions, and renew everything through pungency.
[Mahuang (Ephedra)]
(Shennong Bencao Jing, Middle Category)
Slender and hollow inside, resembling pores. Therefore, it can be used to counteract pores filled with excess pathogens.
[Flavor and Toxicity] Bitter, Warm, Non-toxic.
[Indications] Primarily treats wind-stroke, cold damage, headache, warm malaria, induces sweating to release the exterior, eliminates pathogenic heat, stops cough and rebellious Qi, removes chills and fever, and breaks up mass accumulations.
[Analysis] It is said: The best quality comes from Xingyang, Zhongmu, and Bianjing. In these places, snow does not accumulate in winter. Seedlings emerge in February, slender, strong, and straight; yellow outside, red inside, hollow in the middle with nodes like bamboo; in April, yellow flowers bloom at the tips, bearing fruits tight and small like lily petals, yet resembling soap pod seeds but sweet-tasting; roots are purple-red, divided into male and female types, with females flowering and fruiting. For processing, remove roots and nodes, boil for about ten boils, skim off white foam, lest it cause restlessness (as Mahuang root and nodes stop sweating). Nanpu (Magnolia Bark) and Baiwei (Cynanchum Root) act as guides. It is incompatible with Xinyi (Magnolia Bud) and Shiwei (Pyrrosia Leaf).
[Commentary] It is said: Yellow outside, red inside, hollow shape symbolizes the Li Trigram (Fire); growing without being covered by snow, it aligns with assisting the Heart King (Heart Master) and proclaiming Fire commands. It primarily treats wind-cold and warm malaria, targeting the meridians manifesting headache, invading the superficial layers of skin, causing pores to become full and solid, and disrupting the opening and closing of couli. It promotes Fire governance, raises fluids into sweat, and dilates the 84,000 pores, none disobeying the command, thereby eliminating pathogenic heat. However, heat is not the root of disease but rather a condition marked by invasion, where the fierce energy of wind-cold causes pores to close completely leading to heat; its penetrating nature has not reverted to the original cold nature of the body's Qi. Cough and rebellious Qi occur because closed pores prevent Qi distribution and exhalation, causing Qi to rebel upward. Masses and accumulations form because Qi falsely takes shape, unable to transition from closing to opening, resulting in hard masses. Not only does the inherent nature not change, but the original Qi remains unaltered, allowing it to still transform from inward to outward, changing Winter to Spring; otherwise, reckless sweating would deplete fluids and disrupt the Heart Master.
